Column Chechking While Updating
Jan 3, 2004
If amc.amc2>0 then
“UPDATE amc set AMC2= AMC2 + “ & val(txtamt.text) & “where am1=1”
else if amc.amc2<0 then
“UPDATE amc set AMC2= “ & val(txtamt.text) & “where am1=1”
end if
Here I check the value of column with if condition statement. I need to check the column with out if condition statement.
What is my doubt is that how I can check value of amc2 column while updating.
eg: update amc set case when amc2>0 then AMC2= AMC2 + “ & val(txtamt.text)
like this
Is it possible with “case-when -end”?
If it is possible I can solve a big problem in my project.
Can you give me an example with this query?

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!

Please excuse my ignorance. I've researched this and it appears I am asking to do something that is ridiculous, so please let me know what is wrong with my design (or my brain). I'd like to update an ID number in a table. It is an identity column. In my solution I'm adding a lot of new entries into my table and deleting old ones. Call me anal, but It's driving me nuts that my ID numbers are growing so large so quickly and that I have so many unused ID's. If you were to look over my data ID's they would be something like 1,3,45,78,88,89,103,140,219. What I'm trying to do is renumber my data so that my data currently at say ID# 1067 can be moved to the unused ID#2, etc. So I either need a way to update an Identity column...or I need a way find the lowest unused number among a list of ID's. So is there anyway to achieve what I am trying to do? I see this guy had my same OCD issue (without a solution) :-(

Does anyone know of the SQL statement to add additional comuns to an existing table. I know i can do it through enterprise managaer, but I want to see if I can do it from query analyzer or some script to add columns without having to recreate the table. Or a way to save off the data and recreate the table then placing data back in? I hope that makes sense. I am thinking of this from the sens of doing all updates through source safe
Thanks!

Hi all,
I'm trying to update various rows in my DB with a new value once an action occurs. I am using the following code which does not throw any exceptions, but also does not change the values. Can someone steer me in the right direction?
public static void ChangeRefCode()
{
SqlConnection dbConn = new SqlConnection(ConnectDB.getConnectString());
SqlDataAdapter dataAdapt = new SqlDataAdapter("Select * from Posting",dbConn);
DataSet ds = new DataSet();
SqlCommandBuilder sqBuilder = new SqlCommandBuilder(dataAdapt);
dataAdapt.Fill(ds, "Posting");
foreach (DataRow dr in ds.Tables["Posting"].Rows)
{
dr["ref_code"] = DateTime.Today.Ticks + "-" + dr["poster"].ToString();
}
try
{
dataAdapt.Update(ds, "Posting");
}
catch (Exception ex)
{
ex.ToString();
}
finally
{
dbConn.Close();
}
}

SET Blog = 'yes'
Where Blog = '(null)'

My goal is to with one update statement, fill TABLE1.counter (currently empty) with the total count of TABLE2.e# (employee). Also, if TABLE1.e# isn't in TABLE2.e# then it sets it to "0" (TABLE1.e# 8 and 9 should have a counter of 0) This is for sqlplus.
e.g. TABLE2:
e#
--
1
2
3
4
5
5
6
7
7
1
2
3
4
5
UPDATE TABLE1
SET counter = (
SELECT COUNT(TABLE2.e#)
FROM TABLE2 INNER JOIN TABLE1 ON (TABLE2.e# = TABLE1.e#)
GROUP BY TABLE2.e#);
--^Doesn't work
so my TABLE1 should be:
e# counter
-----------
1 .. 2
2 .. 2
3 .. 2
4 .. 2
5 .. 3
6 .. 1
7 .. 2
8 .. 0
9 .. 0
(The .. is just spacing to show the table here)

I have an update where I need to replace the first two numbers of a string with SF and remove the last number - e.g.:

I have an update statement which works in Oracle, but I cannot get it to work in SQL Server. The statement is below:
UPDATE oraowner.ems_sam
SET sam_id = replace(sam_id,sam_id,'SF'||substr(sam_id, 3, length(sam_id) - 3));

This problem is strictly an SQL problem, and I am about to lose my mind over it. I have a table named Inventory that has a column named PartialQty which is of type DECIMAL(11,4). I have shortened my query for simplicity, but here it is.
DECLARE @pqty1 DECIMAL(11,4)
SELECT @pqty1 = PartialQty FROM Inventory WHERE InventoryID = @invIDPRINT @pqty1 UPDATE Inventory SET PartialQty = 6.5513 WHERE InventoryID = @invID
SELECT @pqty1 = PartialQty FROM Inventory WHERE InventoryID = @invIDPRINT @pqty1
Before this query is ran, the value in PartialQty is 1.2345. If I run this 2 times in a row, this is the output I get:
RUN 1:
1.2345
(1 row(s) affected)
(1 row(s) affected)
(1 row(s) affected)
(1 row(s) affected)
6.0000
RUN 2:
6.0000
(1 row(s) affected)
6.5513
I don't understand 2 things. One is why the first run displays (1 row(s) affected) 4 times even though there is only one record with that InventoryID.
And the other thing I don't understand is why the first time I run it, it loses all of the values after the decimal point.
Please help,
Scott

I am looking for suggestions on how to accomplish the following task with the least amount of hand keying that I can get away with.
I have a main table named Office and 4 other tables that have the Office table ID field value in them.
I have been given a new set of ID values that need to replace the values that are currently in the Office table and then update the ID field in the other 4 tables.
I have only thought of 2 solution and I don’t like either one.
1 Add a new column to the Office table and key in the new ID’s then go through the pages that reference the old ID field and change the SQL queries to use the new field.
2 Change the value of the current Office ID field to the new value. Search the other 4 tables for the old value and then update them to the new value.
Anyone got a better Idea?

If your tables contain created and modified/updated dates what is the best practice for these?
1. Should you use UTC dates?
2. Do you use a default for the creation date (I assume yes)?
3. Should you create a trigger to handle the last update date? Or do you update the column directly in your stored procedures that modify data?
Also, as an aside if you store the user who created/updated the record do you store a foreign key reference to the user table or do you store the username as a varchar? Of course I know you'd normally store the fk, but I wasn't sure if the "logging" nature of the column suggests storing a string value.

Hello,
I have the following stored procedure that inserts records and updates the new record. The parameter @rpt_id has a value of -1 when entering the procedure. It needs to be updated with the new record if (identity) once the record is inserted, bu sometimes the update does not happen. The new records ends up with -1 in the rpt_id column.
I have included the stored procedure. I will appreciate any ideas?

A123 Test

A125 Test
1
Test 9

0
but what I would like is col 1 populated As A123 until it hits A125 Â then populated A125 etc. Â I was thinking about using the iff but not getting anywhere fast.

Hello,
One more question about this Custom Calendar table I'm creating. I have a column called "IsWorkdays" which indicates if the day represented by a row is a workday or not. For our purposes, I also need to create a row that accumulates those numbers by month. So, if it is the 3rd workday of the month, this column would have a 3. This is beyond my current T-SQL ability. Does anyone know how to do this?
Thanks a lot,
Andy

I want to set a column to 0 if it is set to a certain number. There are several columns to check though, so I am wondering if I can do it all in one query, or if I have to do it in single queries?
here is an example:
account | contact_id_1 | contact_id_2 | contact_id_3
433 | 67 | 23 | 67
so I want to set any contact_id_N = 0 where contact_id_N is = 67
so in the end, the table will look like this:
account | contact_id_1 | contact_id_2 | contact_id_3
433 | 0 | 23 | 0
is there a way to do it in one statement?

Hi there.
Is there any way to update the system tables directly, to alter the collations of the columns in the user db's?
I've tried the script below:
UPDATE Syscolumns SET collation = 'SQL_Latin1_General_CP1_CS_AS' WHERE name = '<AddrCode>'
AND id = object_id('<Compliance>')
but, I get the following error message:
Server: Msg 271, Level 16, State 1, Line 1
Column 'collation' cannot be modified because it is a computed column.
Can you please help me! I need to do thousands of these, and most of them has constraints on, so my script I generated to do the ALTER TABLE.... ALTER COLUMN does not suffice.
Thanks.

CREATE TABLE EDI_data_proc_log(
ID int IDENTITY(1,1),
comment VARCHAR(3000),
time_recorded DATETIME DEFAULT GETDATE(),
run_by varchar(100),
duration int );
When a record is inserted I like the duration column to be computed.This should happen only after the first record to the table has gotten inserted.You might say a trigger would be the best.. Ok then, show me the syntax.
Or I am thinking can we write a user defined function that will compute the value for the duration column.
--By default, I would like to update the duration column as follows:
--It should record the number of seconds between the last insertion ( You can get that time from the time_recorded column from the previous record and the current time can be obtained from the getdate() function )
