Updating Rows Of A Column
Apr 10, 2008
Hi, I need to update column week14 in table PastWeeks with data from Eng_Goal and then result of some calculation from table AverageEngTime in the row Goal and Used respectively. I used the following and was not successful. Please advice. Thank you.
Update Pastweeks
set
week14 = (SELECT Eng_Goal,((Mon_Day + Mon_Night + Tue_Day + Tue_Night + Wed_Day + Wed_Night + Thu_Day + Thu_Night + Fri_Day + Fri_Night + Sat_Day + Sat_Night + Sun_Day + Sun_night)* 100/168) FROM AverageEngTime where Shifts = 'Average')
where Weeks = ('Goal','Used' )

I'm looking for some performance assistance on updating a column value in a table that contains approximately 50 million rows. I have a permanent table in another database that has the key column and value to be set. My query is listed below, but I'm afraid it will run quite awhile. Any suggestions would be appreciated.
update mytable
set column2 = b.column2
from mytable as a
join mytable1 as b
on a.column1 = b.column1
There is a one to one relationship between the two tables.

Hi,
I am working on a SQL Server table designed by a partner company and cannot change the data structures. There is a table with a list of people available for calling out to a security system (keyholders).
From a web form, I need to allow my users to change the telephone calling order of the keyholders in the table.
The two important fields are AccountCode nVarChar and CallOrder nVarChar - where AccountCode + CallOrder must be unique.
As an example, the table may contain records with the following data..
1234, 1, Fred
1234, 2, Bert
1234, 3, Bob
If the user wants to make Bob the number 1 keyholder, Fred number 2 and Bert number 3 - what is the best practice for me to approach the update ?
Is this a job for ADO.Net or T-SQL ?
Thanks in advance.
Steve.

Does anybody have a sample SQL script that will select table A and compare it to table B. If a row exists in both table A and table B, it will update the columns in table B with the columns in table A. If the row does not exist in table B, it will insert a row in table B using the row in table A. Is this possible?
Thanks Mitch

I am new here, and I am sure this is a simple query, but im being forcefed database chores from my job, so i have to teach this stuff to myself/get help from places like this,
I need help with a query,
lets say that there are columns a,b,c,d,e,f,g
if columns c,d,e are the same, than I want the info in column g changed to the info in column b in the first record of that group
the reason I am doing this is,
I have like items (sku's) grouped in my database, and i want to create a blanket part number for skus that have matching descriptions which is the information in colums c,d,e,
I want to link them to the part number of the first product with that description, and add that part number in a new column at the end of the grouped SKU's record
this is what i start out with
a b c d e f g
2 4 5 6 9 8
2 5 5 6 9 9
2 7 5 6 0 5
1 2 3 4 5 6
1 3 3 4 5 7
1 4 3 4 5 8
1 5 3 4 5 9
i want to end up with
a b c d e f g
2 4 5 6 9 8 4
2 5 5 6 9 9 4
2 7 5 6 0 5 7
1 2 3 4 5 6 2
1 3 3 4 5 7 2
1 4 3 4 5 8 2
1 5 3 4 5 9 2

I have put this thread on as a follow up discussion to some concepts that surfaced here:http://www.dbforums.com/showthread.php?t=1208316here:http://www.dbforums.com/showthread.php?t=1604936and also here:http://www.dbforums.com/showthread.php?t=1606555 The gist is: Is it ever correct excusable advisable to pass a non-normalised csv list of data to a stored procedure? When I first asked this I thought it was simply an implementation issue. Pat thinks it is but he also holds an ideological objection too. If I seem a little obsessed with this topic it is simply thata) I don't want to hijack yet another threadb) I am Anyway - I PMed Pat about this and he (quite rightly) suggested I post publicly. So here we go: I think I have struggled a little getting my head round the concepts you are using. And here (I think) is why: Normalisation starts with a logical model and ends with the physical implementation of the database (as I see it...). Relational theory pervades these two but extends further to SQL and database objects (views, sprocs etc). I work exclusively (with the exception of some legacy I stuff I simply must update) with the sproc database-API methodology. As such, my databases are abstracted from the other tiers. Now - I think this is the crux of it for me - I typically think of the sproc API as another tier (perhaps tier 1.5). Although the database itself and the objects that manipulate it are housed by a single application I don't actually think of the sprocs as part of the database. They are dependant upon it and inextricably intertwined with it but they are not a part of it in my eyes. As such, I don't worry about producing denormalised output and I have never (up until you got me thinking about it) worried about accepting non-normalised input. The sproc is not the database. The sproc is just a code procedure that acts upon the database. As such - if it accepts a typless, denormalised input but subsequently types (validates) it and normalises it before it makes any changes to the data within the database then I struggle to see the scale of the problem. I am writing as something of a stickler for normalisation myself - I think that rather than querying how closely one should adhere to normalisation principles I am pondering at what point these principles come into play. As a follow up question - if SQL Server sprocs were to accept (for example) a table variable as an argument would this meet your requirement (since the data is verified and normalised before it gets to the sproc) or would you require a solution like this to be an ANSI Standard too? So - that's the nub of it - comments welcome ona) The practicality of passing csv lists to sprocs and subsequently parsing them and b) How "correct" or "incorrect" this is. Blindman and Pat both object on both counts (I think).Thrasmachus didn't have a problem with it (however to be fair that was a very early response to a specific question I asked). I don't hold a particularly strong opinion either way – in fact the “loop through the changes at the client and fire the sproc n times” route is probably much easier to code in any case - I'm just interested in the idea that it violates relational theory in some way.

Hi,
I am preparing a project that contains multiple tables, because of huge operations to be performed, so i split these into two forms. I used one form for "Inserting Data in the multiple tables" and another form used for "Updating and Deleting Data from the multiple tables". I used a common identification number in all the tables are "License_Number" for inserting, retreving, updating and deleting the data. I used tabcontrol to place lot of controls on it.
The form-1 which is used for Inserting, works fine.
The problem occuring in the second form which i used for updating.
The following code fill the data into the Textboxes and as well as in the datagridview. Below two tables "SetBack_Details" and "Far_Details" are fill the data in datagridview.
Private Sub FillDataFromAllTables(ByVal LicenseNumber As Long)
Try
'Fill Owner Personal Details Data
CheckOwnerID = RetrieveOwnerIDFromPD(LicenseNumber)
Me.Owner_Personal_DetailsTableAdapter.Fill(Me.LicenseFARModifyDataSet.Owner_Personal_Details, CheckOwnerID)
'-------------------------------------------------------------------
'Fill Project Details Data
Me.ProjectDetailsTableAdapter.Fill(Me.LicenseFARModifyDataSet.ProjectDetails, LicenseNumber)
'-------------------------------------------------------------------
'Fill Consultant Details Data
Me.Consultant_DetailsTableAdapter.Fill(Me.LicenseFARModifyDataSet.Consultant_Details, LicenseNumber)
'Fill Applicant Details Data
Me.Applicant_DetailsTableAdapter.Fill(Me.LicenseFARModifyDataSet.Applicant_Details, LicenseNumber)
'-------------------------------------------------------------------
'Fill Property Details Data
Me.Property_DetailsTableAdapter.Fill(Me.LicenseFARModifyDataSet.Property_Details, LicenseNumber)
'-------------------------------------------------------------------
Me.SetBack_DetailsTableAdapter.Fill(Me.LicenseFARModifyDataSet.SetBack_Details, LicenseNumber)
'-------------------------------------------------------------------
Me.FAR_DetailsTableAdapter.Fill(Me.LicenseFARModifyDataSet.FAR_Details, LicenseNumber)
Catch ex As Exception
MessageBox.Show(ex.Message.ToString, "Project Details")
End Try
End
The data which i retrieves in a single record easily updated but problem occurs in DataGridView.
The data which binds to textboxes is easily updating because of a single record. Example is below
UPDATE PROJECTdETAILS SET PNAME=@PNAME, ZONE=@ZONE, ZONEAREA=@ZONEAREA WHERE LicenseNumber=@LicenseNumber
The data which binds to datagridview is problem. I know the following statement is not appropriate to update the data rows in datagridview.
UPDATE SETBACK_DETAILS SET DIRECTION=@DIRECTION, BORDERS=@BORDERS, DIMENSION=@DIMENSION WHERE LICENSENUMBER=@LICENSENUMBER
What happening to the above statement is , all rows with this LICENSENUMBER contains same data. Before updating data contains in different information but after updating which ever last row is updating, it contains the last row values to all records.
Example :
101 xyzcompany X-Road X-Area
101 xyzcompany X-Road X-Area
101 xyzcompany X-Road X-Area
101 xyzcompany X-Road X-Area
101 xyzcompany X-Road X-Area
.
.
The following code i used to save the data
Private Sub SaveData()
Me.ValidateChildren()
Me.ProjectDetailsBindingSource.EndEdit() 'EndEdit for Project Details
Me.Consultant_DetailsBindingSource.EndEdit() 'EndEdit for Consultant Details
Me.Applicant_DetailsBindingSource.EndEdit() 'EndEdit for Applicant Details
Me.Property_DetailsBindingSource.EndEdit() 'EndEdit for Property Details
'Me.SetBack_DetailsBindingSource.EndEdit() 'Endedit for SetBack_Details
Me.ProjectDetailsTableAdapter.Update(Me.LicenseFARModifyDataSet.ProjectDetails) 'Update Project Details
Me.Consultant_DetailsTableAdapter.Update(Me.LicenseFARModifyDataSet.Consultant_Details) 'Update Consultant Details
Me.Applicant_DetailsTableAdapter.Update(Me.LicenseFARModifyDataSet.Applicant_Details) 'Update Applicant Details
Me.Property_DetailsTableAdapter.Update(Me.LicenseFARModifyDataSet.Property_Details)
'Me.SetBack_DetailsTableAdapter.Update(Me.LicenseFARModifyDataSet.SetBack_Details)
End Sub
Please help me in the regard how to update the data in DataGridView which contains multiple recrods with different information for a single LicenseNumber. I try so many times with different sort of techniques but i fails, sometimes i get concurrency violation error and many more.
Hope anybody understand my problem. Please help me in this regard.
Thanks.
Best Regards,
Kashif Chotu

I need to update a empty column in our SQL database with the login ID for employees of our company.The table is called SY01200 and were I need to put the login ID is column INET5, and the login ID is just me stripping off the company's email address(removing the @company.com), and I need to update the INET5 column only where Master_Type = 'EMP'
And here is the Query that I am using to strip the email select LEFT(convert(varchar(40),EmailToAddress),LEN(convert(varchar(40),EmailToAddress))-14) As LoginName from sy01200 where Master_Type = 'emp'And here is what I thought the Query would be to update however I got and error saying more than 1 arguement returned
UPDATE sy01200
SET INET5 = (select LEFT(convert(varchar(40),EmailToAddress),LEN(convert(varchar(40),EmailToAddress))-14) As LoginName from sy01200 where Master_Type = 'emp')

I have a production table with 400 million rows.
I have a staging table which has 48 million rows. This data is the same as the production data, except one column has a different value.
Create Table Production
(
Id Int Identity(1,1),
Code Varchar(20),
ReferenceSequence int
)
-- Staging Table
Create Table Staging
(
Code Varchar(20),
NewSequence int
)
I need to update the production table with the newSequence value from staging to replace the ReferenceSequence. I.e:
Update Production
Set ReferenceSequence = Staging.NewSequence
From Staging
where Production.Code = Staging.CodeHowever, updating 48 million rows at once will generate a lot of logging!
How can I do 1 million rows at a time, commit the changes then do the next million?
I've tried some of the examples on the following page [URL], but they look to just update the tables with the same values.

Hi,
I have a table called "tblProducts" with following fields:-
ProductID(Pk, AutoIncrement), ProductCode(FK), ProdDescr.
So to the above table I have added a new field/column named "ProdLongDescr(varchar, Null)"
So, I need to populate this newly added column with specific values for each row depending on "ProductCode" which is different forevery row. The problem is that I have 25 rows.So instead of Writing 25 individual update scripts, is there a way in which single query will do the same job instead of writing one update query for each row ?. If so can some one guide me how to achieve that OR point to me a good resource.
Below are a couple of Individual update scripts I Wrote. "ProductCode" is different for all 25 rows.
Update tblValAdPackageElement SET ProdLongDescr = 'Slideshows' WHERE ProductCode = 'SLID'
And szElementDescr='Slideshow'
if @@error <> 0
begin
goto ErrPos
end
Update tblValAdPackageElement SET ProdLongDescr = 'CategorySlideshows' WHERE ProductCode = 'SLDC'
And szElementDescr='CategorySlideshow'
if @@error <> 0
begin
goto ErrPos
end

1> Sort the table based on Start Date (the picture shown is already sorted..) for example first 6 rows for AK - Anchorage
2> select the rows with same city (rows 1-6)
3> Select the rows with distinct start date (rows 1-3-5)
4> Change the End Date of the second selected row (row 3 in this case) to I day below the start date of 1 selected row. (4/1/2007 €“ 1 day = 3/31/2007)
5> proceed till end of selected rows.. 1-3-5
6> do the same thing for rows 2 and 4.
7> follow the same procedure for rest of the file.
The selected file should look like this when done..

I need to update about 1.3 million rows in a table of mine.
I am getting the data from one of the columns of the same table and
updating the new column.
I am doing this using a cursor which I have put in a stored procedure.
As this is a production table which users might be accessing.It is a
web based application and I can't slow the system down.
So I am willing to run the stored prcedure during off peak hours.
However, do I need to put this in a transaction?
If I did put it in a transaction what type of isolation level should I
opt for?
Data integrity is very important for me and I don't mind to compromise
on the performance.
I am doing this because one of the columns which has "short description"
entry is has become too small for business purposes and we want to increase it's
length from varchar(100) to varchar(150).
As this is SQL 6.5, I can't increase the lenght of the column.
So Iadded a new column and will run the stored proc.
What precautions are to be taken?
This is on a high priority basis and very important too.
Thanks in advance...
Stored procedure code:
USE DB_Registration_Dev
GO
IF EXISTS (SELECT NAME FROM SYSOBJECTS WHERE NAME='usp_update_product' AND TYPE='P')
DROP PROCEDURE usp_update_product
GO
CREATE PROC usp_update_product
AS
DECLARE @short_desc varchar(100)
DECLARE @prod_id int
DECLARE sdesc_curs CURSOR
FOR
SELECT [Product].[product_id] , [Product].[short_description]
FROM Product
OPEN sdesc_curs
FETCH NEXT FROM sdesc_curs
INTO @prod_id, @short_desc
WHILE @@FETCH_STATUS = 0
BEGIN
UPDATE Product
SET [Product].[sdesc] = @short_desc
WHERE Product_id=@prod_id
FETCH NEXT FROM sdesc_curs
INTO @prod_id, @short_desc
IF @@FETCH_STATUS <> 0
PRINT ' Finished Updating the table...go ahead and have fun ...! '
END
DEALLOCATE sdesc_curs
GO

Hi I haven't included DDL etc as this is theoretical at this time. I can rustle up an illustrative example if required.Following applies to disconnected environment. In general, most edits are broad (i.e. n fields affected) against a single record. However, there are certain circumstances where a single field will be edited against a deep (n) set of records. So business request:User needs to access and edit n records at a time (for arguments sake n is unlikely to be enourmous - say 50 max) but only editing one single field, and always the same field. The values for this edited field will differ for each record. Initially retrieving data for the app is no problem, nor is identifying those records that have been edited. What is the best means of updating the table? There are, to my mind, three ways of dealing with the latter senario - 1) Client calls the server n times editing a record at the time.2) Client creates a csv string and passes to sproc. Sproc parses string using some UDF split function (probably chucking into table variable) and updates using a single set set based operation.3) Client creates some flat file or other that is BULK inserted (or similar) by SQL Server. 3 - I think would only be an option if n was a very large number and or having the changes immediately reflected in the data is not priority.1 - would create a chatty app and presumably put the most load on the server. So I am left thinking 2 is (depending on circumstances) the best method. Is this fair? Are there any particular considerations gotchas I should be aware of? I know where to get hold of as many TSQL split functions as I could want so I'm not looking for code just opinions. OR - am I just plain wrong? Is there a better alternative or am I dismissing the other two methods prematurely? Thanks in advance

I'm using a stored proceedure which should update a number of rows in atable depending on a key value supplied (in this case 'JobID').

Hello All
I am trying to figure out if what i am attempting to do is possible and whether or not my approach is wrong to begin with.
I am trying to build a custom report for our accounting system which is Traverse from Open systems. This is what i have done in the stored procedure thus far
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS ON
GO
ALTER PROCEDURE rptArFLSalesByCustItemized_sp
@custId pCustID,
@dateFrom datetime,
@dateThru datetime,
@itemIdFrom pItemId,
@itemIdThru pItemId
as
set nocount on
-- define some variables for previous year
declare @LYqty int, @LyAmt money, @LYfrom datetime, @LYthru datetime
-- set defaults
SET @itemIdFrom=ISNULL(@itemIdFrom,(SELECT MIN(itemId) FROM tblInItem))
SET @itemIdThru=ISNULL(@itemIdThru,(SELECT MAX(itemId) FROM tblInItem))
SET @LYfrom=DATEADD(YEAR,-1,@dateFrom)
SET @LYthru=DATEADD(YEAR, -1, @dateThru)
-- create small temp table to hold customer info
Create Table #tmpArCustInfo
(
custId pCustID,
custName VARCHAR (30),
)
-- populate customer temp table with info
Insert into #tmpArCustInfo
select custId, custName
from tblArCust
WHERE custId = @custId
-- create a temp table to hold the Data for each Item
Create Table #tmpArSalesItemized
(
itemId pItemId,
productLine VARCHAR (12),
pLineDesc VARCHAR (35),
descr VARCHAR (35),
LYQtySold int,
LYTDQtySold int,
QtySold int,
LYTDsales money,
totalSales money,
LastInvDate datetime,
)
-- populate the temp table with all of the inventory items
insert into #tmpArSalesItemized
select ii.itemId, ii.productLine, ip.Descr, ii.Descr, 0,0,0,0,0, NULL
from tblInItem ii, tblInProductLine ip
where ip.productLine = ii.productLine
AND ii.itemId BETWEEN @itemIdFrom AND @itemIdThru
-- update table with this years quantities
update #tmpArSalesItemized
SET QtySold = (select SUM(QtyOrdSell) from tblArHistDetail hd
where TransId IN (select TransId from tblArHistHeader where custId = @custId)
AND orderDate IN (select OrderDate from tblArHistHeader where OrderDate BETWEEN @dateFrom AND @dateThru)
AND hd.partId BETWEEN @itemIdFrom AND @itemIdThru
GROUP BY hd.partId
)
-- Return the temp tables results
select * from #tmpArSalesItemized, #tmpArCustInfo
drop table #tmpArSalesItemized, #tmpArCustInfo
return
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
My problems begin where i want to start updating all of the Qty's of the QtySold field. I have managed to get it to write the same sum in every field but i cannot figure out how to update each row based on the sum of the qty found for that item in the tblArHistDetails table, trouble is too that there is no reference to the custId in that table either. The custId resides in tblArHistHeader and is linked to the details table via the TransId column. So really i need to update many rows based on criteria from 2 other tables.
Can anyone please help? I dont have a clue how to make this work, and most of what i have learned about sql thus far has been from opening other stored procs etc in the accounting system and just reading to see how the developers have done things.
Thanks
Jamie

I have to write a couple scripts that will update a couple columns in two separate tables and also insert a new row with the same data except for a few calculated or provided values ...... see specs below ...
1. tGradeHist Table Script One (Needs to be run first)
a. Read tGradeHist Table and Select rows with GradeEndDate = NULL and GradeStartDate = '1/1/2007 12:00:00 A.M.'
b. Calculate New Step Amount = StepAmount * Incr% (Round To Nearest Whole Dollar)
c. Create New Row for this table using information from row read above and insert new information where indicated :
GradeCode - Same
GradeLocationCode - Same
Step - Same
GradeStartDate - '7/1/2007 12:00:00 A.M.'
GradeEndDate - NULL
GradeCurrencyCode - Same
StepAmount - Result of b (above)
GradeFrequencyCode - Same
RangeMaximumAmount - Same
RangeMidAmount - Same
RangeMinimumAmount - Same
GradeCurrentFlag - 'True'
MarketMaximumAmount - Same
MarketMidAmount - Same
MarketMinimumAmount - Same
GradeGUID - Same
TSCOL - Same
d. Update Row read in a (above) with GradeEndDate = '6/30/2007 12:00:00 A.M.' and GradeCurrentFlag = 'False'
2. tPersonBasePayHist Table Script Two (Needs to be run second)
a. Read tPersonBasePayHist Table and Select rows with PersonBasePayEndDate = NULL
b. Calculate New PersonBasePayAmount = PersonBasePayAmount * Incr% (Round To Nearest Whole Dollar)
c. Create New Row for this table using information from row read above and insert new information where indicated :
PersonGUID - Same
PersonBasePayStartDate - '7/1/2007 12:00:00 A.M.'
PersonBasePayEndDate - NULL
PersonBasePayCurrencyCode - Same
PersonBasePayAmount - Result of b (above)
PersonBasePayFrequency - Same
PersonBasePayPayrollFrequencyCode - Same
BasePayReasonCode - 'SA'
ConductedBasePayReviewDate - Same
ScheduledBasePayReviewDate - Same
PayrollCode - Same
PersonBasePayCurrentFlag - 'True'
ApprovedByPersonGUID - Same
PersonBasePayGUID - Same
TSCol - Same
d. Update Row read in a (above) with PersonBasePayEndDate = '6/30/2007 12:00:00 A.M.' and PersonBasePayCurrentFlag = 'False'

This question is extension from the topic Updating table Rows with overlapping dates:Â [URL] .....
I am actually having a table as following:
Table Name: PromotionList
Note that the NULL in endDate means no end date or infinite end date.
ID PromotionID StartDate EndDate Flag
1 1 2015-04-05 2015-05-28 0
2 1 2015-04-23 NULL 0
3 2 2015-03-03 2015-05-04 0
4 1 2015-04-23 2015-05-29 0
5 1 2015-01-01 2015-02-02 0
And I would like to produce the following outcome to the same table (using update statement): As what you all observe, it merge all overlapping dates based on same promotion ID by taking the minimum start date and maximum end date. Only the first row of overlapping date is updated to the desired value and the flag value change to 1. For other overlapping value, it will be set to NULL and the flag becomes 2.
Flag = 1, success merge row. Flag = 2, fail row
ID PromotionID StartDate EndDate Flag
1 1 2015-04-05 NULL 1
2 1 NULL NULL 2
3 2 2015-03-03 2015-05-04 1
4 1 NULL NULL 2
5 1 2015-01-01 2015-02-02 1
The second part that I would like to acheive is based on the first table as well. However, this time I would like to merge the date which results in the minimum start date and End Date of the last overlapping rows. Since the End date of the last overlapping rows of promotion ID 1 is row with ID 4 with End Date 2015-05-29, the table will result as follow after update.
ID PromotionID StartDate EndDate Flag
1 1 2015-04-05 2015-05-29 1
2 1 NULL NULL 2
3 2 2015-03-03 2015-05-04 1
4 1 NULL NULL 2
5 1 2015-01-01 2015-02-02 1
Note that above is just sample Data. Actual data might contain thousands of records and hopefully it can be done in single update statement.
Extending from the above question, now two extra columns has been added to the table, which is ShouldDelete and PromotionCategoryID respectively.
Original table:
ID PromotionID StartDate EndDate Flag ShouldDelete PromotionCategoryID
1 1 2015-04-05 2015-05-28 0 Y 1
2 1 2015-04-23 2015-05-29 0 NULL NULL
3 2 2015-03-03 2015-05-04 0 N NULL
4 1 2015-04-23 NULL 0 Y 1
5 1 2015-01-01 2015-02-02 0 NULL NULL
Should Delete can take Y, N and NULL
PromotionCategoryID can take any integer and NULL
Now it should be partition according with promotionid, shoulddelete and promotioncategoryID (these 3 should be same).
By taking the min date and max date of the same group, the following table should be achieve after the table is updated.
Final outcome:
ID PromotionID StartDate EndDate Flag ShouldDelete PromotionCategoryID
1 1 2015-04-05 NULL 1 Y 1
2 1 2015-04-23 2015-05-29 1 NULL NULL
3 2 2015-03-03 2015-05-04 1 N NULL
4 1 NULL NULL 2 Y 1
5 1 2015-01-01 2015-02-02 1 NULL NULL

Hi,
I have an application where I'm filling a dataset with values from a table. This table has no primary key. Then I iterate through each row of the dataset and I compute the value of one of the columns and then update that value in the dataset row. The problem I'm having is that when the database gets updated by the SqlDataAdapter.Update() method, the same value shows up under that column for all rows. I think my Update Command is not correct since I'm not specifying a where clause and hence it is using just the value lastly computed in the dataset to update the entire database. But I do not know how to specify a where clause for an update statement when I'm actually updating every row in the dataset. Basically I do not have an update parameter since all rows are meant to be updated. Any suggestions?
SqlCommand snUpdate = conn.CreateCommand();
snUpdate.CommandType = CommandType.Text;
snUpdate.CommandText = "Update TestTable set shipdate = @shipdate";
snUpdate.Parameters.Add("@shipdate", SqlDbType.Char, 10, "shipdate");
string jdate ="";
for (int i = 0; i < ds.Tables[0].Rows.Count - 1; i++)
{
jdate = ds.Tables[0].Rows[i]["shipdate"].ToString();
ds.Tables[0].Rows[i]["shipdate"] = convertToNormalDate(jdate);
}
da.Update(ds, "Table1");
conn.Close();
-Thanks

Hi,Its probably simple but.. How do I update a column by just '1'..for example - heres my code: protected void Button1_Click(object sender, EventArgs e) { SqlConnection con = new SqlConnection(); con.ConnectionString = "HiddenConnection"; con.Open(); SqlCommand command = new SqlCommand(); command.Connection = con; Label productIDLabel = (Label)DataList1.FindControl("productIDLabel"); command.CommandText = "UPDATE Items SET numberclickedin = numberclickedin + 1 WHERE productID=@productID"; command.Parameters.Add("@productID", productIDLabel.Text); command.ExecuteNonQuery(); con.Close(); command.Dispose(); } As you can see in the bold text, I want to add 1 to the numberclickedin column.. and in my primative way Ive just typed +1What should I use instead?Thanks in advance,Jon

How can I create an update statement that will allow me to fill in a column if the previous column already has data in it? I am trying to do and UPDATE/SET command that allows me to extract information and populate columns within a table. However, the UPDATE/SET has to make sure that it is not overwriting information that is already in the column and if there is, to populate the column next to it, and so on until all the columns are populated.
Here is my table:
Code:
create table #add_diags(
add_diag_1 varchar(10) null,
add_diag_2 varchar(10) null,
add_diag_3 varchar(10) null,
add_diag_4 varchar(10) null,
add_diag_5 varchar(10) null,
add_diag_6 varchar(10) null,
add_diag_7 varchar(10) null,
add_diag_8 varchar(10) null
)
In my UPDATE/SET I am pulling data from another table to populate into the 'add_diag' columns however, I'm not sure how to write in SQL the ability to monitor all the columns, and if for example the first three are full to then populate into the fourth and so on.
Here is my UPDATE/SET statement (while involved, I think I need something in my WHERE clause in order for this to be resolved):
Code:
update ad
set add_diag_1=dsm_code
from #add_diags ad
join Doc_Entity de
on ad.patient_id=de.patient_id
and ad.episode_id=de.episode_id
and doc_code = 'DCDIAG'
join Patient_Assignment pa
on de.patient_assignment_id = pa.patient_assignment_id
and convert(char(8),de.effective_date,112) = convert(char(8),pa.date_discharged,112)
left outer join Doc_Diag_Axis_I_III dx1
on de.doc_session_no=dx1.doc_session_no
and de.current_version_no=dx1.version_no
where dx1.sequence_no=2
and de.is_locked = 'Y'
and dx1.rule_out = 'N'
and is_billable = 'Y'
and dx1.axis_type IN ('1','2')
and de.status in ('CO' , 'SA')
Any ideas? Thanks!
