I would like to update a varchar field with an update statement that appends information to what is currently stored in the field, for example in the Statement field I may currently have a name (Mark) and I want to add a unique identifier to the end of the name so that it may look like, Markq1572, is there a way to do this in an update statement?

I'm having a problem updating a varchar(4000) column in Enterprise Manager when I open the table and try to update one particular row directly. Most of my rows have approx. 100-500 characters in this column, and I can update all of them them, but one row which has 1976 characters in this varchar column doesn't let me change data by typing directly into this column, although it will let me update other columns in the same row. Altogether, my row size has a max. of approx. 5000, below the 8060 limit, so I doubt that's the problem. What Is?
Thanks,
Sarah
Hi,
What is the difference updating a null value to char/varchar type column
versus empty string to char/varchar type column?Which is the best to do and why?
Could anyone explain about this?
Example:
Table 1 : tCountry - Name varchar(80) nullable
Table 2 :tState - Name char(2) nullable
Table 3 :tCountryDetails - countryid,state (char(2) nullable) - May the country contain state or no state
So,when the state is not present for the country ,i have two options may be - null,''
tCountryDetails.State = '' or tCountryDetails.State = null?
Hi,I have a website using a SQL Server database to store all of it's data.Retrieving data and writing basic data back is fine, however, when i goto update one table that has a text field in it the update fails ifthe amount of data being passed to the text field is too large.Is there a way around this or a particular update i should be using?Any information would be greatly appreciated.CheersBj
View 8 Replies View RelatedI'm having some problems importing data from a memo column (Access) into varchar column in SQL Server.
My idea was to use slowly changing dimesion to identify modified and new rows. No matter what data type I use to convert the memo column (using Data Conversion Transformation) and then using the converted column in SCD, I get the following error :
'The SCD transform does not allow mapping between columns of different types except for DT_STR and DT_WSTR.'
What do I have to do to get Memo column 'to behave' as a string?
Same problem with a different data type - decimal (18,5) in sql server - no matter what datatype I use in Data Conversion Trans, I get the same error trying to generate scd.
Thank you for your answers.

I am trying to update records based on the results of a query with a subquery.
The result set being produced shows the record of an item number. This result produces the correct ItemNo which I need to update. The field I am looking to update is an integer named Block.
When I run the update statement all records are updated and not the result set when I run the query by itself.
Below you will find the code I am running:
create table #Items
(
ItemNovarchar (50),
SearchNo varchar (50),
Historical int,
Blocked int
[Code] ....
Below is the code I am using in an attempt to update the block column but it updates all records and not the ones which I need to have the Blocked field set to 1.
Update #items set Blocked = 1
Where Exists
(
SELECT ItemNo=MAX(CASE rn WHEN 1 THEN ItemNo END)
--,SearchNo
--,COUNT(*)
[Code] ...
Why is the update changing each record? How can I change the update to choose the correct records?
Am converting varchar field to float and summing using group by and next inserting to varchar field(table).
while inserting float value it is converting to exponential ex:1.04177e+006 but if i execute only select statment actual float value will get display ex:1041765.726
My question is why it is converting while inserting ? and how to avoid it.
select query : SUM(CONVERT(float,(rtrim(REPLACE(REPLACE( column1, CHAR(13), ' '), CHAR(10), ' '))))) as AggregateValue
i want to import/copy a varchar field numeric data in to number field pls suggest the solution

Hello,
I have a table with a column that is currently a varchar(50), but I want to convert it into an int. When I try to just change the type in design mode I get an error that conversion cannot proceed. When I look at the field it appears some of the entries have special characters appended at the end, I see a box after the value.
How can I remove all speical characters and then convert that field to an int?
Also I tried the following query which did not work as well, same error about conversion.
UPDATE myTable SET field = CAST(field AS int)
I'm trying to find a specific string (a name) and replace it with another inside of a VARCHAR(7000) field. Unfortunately, there are names like Ted and Ken that I'm trying to replace. I would like to leave words like Broken, admitted, etc... intact.
UPDATEtbl
SETBody = LEFT(REPLACE(tbl.Body, pm.OldFirstName, p.FirstName), 7000)
FROM Table tbl
JOIN Person p ON p.PersonID = tbl.PersonID
JOIN PersonMap pm ON pm.PersonID = p.PersonID AND LEN(pm.OldFirstName) > 2
WHEREtbl.Body LIKE '%[^a-z]'+pm.OldFirstName+'[., ]%
'The problem I'm running into is that the '[, ]%' in the LIKE excludes any record that ends with the FirstName because it is requiring either a space, comma or period after the name. Is there some way to add an empty string to the list of acceptable characters as that would cover any scenario in the data? I would prefer not to add all characters except space, comma and period, but I guess I could do that.
I am really lost understanding using SQL Server 2000 with ASP.net Webb apps. If you are dong windows apps, the form builder wizard will either build you a page with a grid for displaying multiple records, or a single record page with text boxes.
All well and good.
With ASP.net web apps, though, you only get the option for making the gred/multiple record page.
So I try to make a page with textboxes to use to update my table in Sequel Server. I do my data binding, and fill my adapter, and viola, the data from my first row appears in the text boxes.
Here is the problem. I have a "Next" button and a "Previous" button that I want to use to move forward or backward through the rows in the table. What code do I put behind the buttons?
I created a windows app and used the dataform wizard to make a single record form. The code it puts behind the "Next" button is
Private Sub btnNavNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNavNext.Click
Me.BindingContext(objDS_SclRcd, "IMA_School").Position = (Me.BindingContext(objDS_SclRcd, "IMA_School").Position + 1)
Me.objDS_SclRcd_PositionChanged()
End Sub
I tried to incorate the logic into my ASP web page, but can't figure out how to do it.
It seems like it ought to be simple, like position = position + position, but I can't figure it out.
Also, after I enter data changes, how do I save the updated data from the screen to the data set before moving on to the last record?
Last, how do I tell the dataset to go back and update the connextion server?
I really want to be able to update SQL data from a remote client usuing ASP web page, but none of my manual address how to do it.
Any help would be great.
Thanks
Jim
I have a textbox that is receiving a date in the format mm/dd/yyyy. The field in the database is VarChar size 10. I purposely don't want to use the DateTime data type for various reasons. When I extract the text from that textbox:
Example:4/11/2005
I do my INSERT. When I look in the database at that field, it shows up like:April 11, 2005 12
The database's field is VarChar! How/why is it doing automatic DateTime formatting?
Greeetings!

I need to update one row in a SQL Server 6.5 DB from a row in SQL 2000 server DB. What would be the best way to do this?

Hi All,I'm a relatively newbie to SQL Server 2000, having come from a MySQLbackground.I'm creating my first Trigger statement on a table, and I'd like toknow how I go about performing an update on the row that was changedwhen the trigger was fired.To explain, I have 2 columns, one which contains a member number, theother which contains a flag that is supposed to indicate whether ornot the member number in the row has changed since the last time thetable was processed for updates.So, whenever the value in the member number field [memnum] is updated,I want to set the flag [igproc] to true.The best I've been able to do is:CREATE TRIGGER [updateignoreprocflag] ON [dbo].[dd_testtable]FOR UPDATEASdeclare @key as intIF UPDATE (memnum)select @key = recid from insertedUPDATE dd_testtable set igproc=1 where recid=@keyThis seems to work, but I'd like to know if there's a better way ofretrieving the recid value of the changed row to pass to the UPDATEstatement? Also, I read somewhere in passing that using SELECTstatements and variable assignments within triggers can cause problemswhen called from other applications; in this case it will either be aweb site using ASP.or an application developed in FOXPRO. I can't findwhere I read this originally, so it's entirely possible I imagined itor misunderstood it, but I'd very much appreciate it if someone couldconfirm whether or not this is the case?Many, many thanks in advance!Much warmth,Murray

I need immediate help with a query that I am trying to write. I want to sum the values in a query but the field has a type of varchar and it has decimal numbers too. So if I do the query something like that, that converts the field to int, I get the error message.
I tried converting it into real or float but I get error message on that too. I need help with adding the calculatedValues and getting there sum. I would appreciate any help with that.
Thanks

After reading Dan Guzman's blog entry (http://weblogs.sqlteam.com/dang/archive/2008/02/21/Dont-Bloat-Proc-Cache-with-Parameters.aspx) I started modifying some of my code to try it out and ran into a stumbling block. What size would you specific for a varchar(MAX) field?
Since a varchar max field can hold up to 2 billion chracters I really don't think I need to specify 2 billion as the size. Anyone have any ideas?
I have a varchar column which containd comma delimited values like
Rec# Fruits
1 Apple, Peach, Strawberry
2 Orange, Mango
3 Banana, Grape
...........
Now i have to add search facility so that a user could search for more than 1 fruit at a time. I have a Stored Procedure which returns records from this table. that SP has a Parameter @SearchFruit Varchar(500) and the user could pass in values like 'Apple, Mango' to this parameter.
Now how should i write the SQL so that i get back the records Rec# 1 & 2 since apple is there in 1st record and mango is there in the 2nd ??
I know if a put the comma delimited values as individual records in a temporary table and also do the same for the parameter values then i can get the desired results. But i want to avoid doing that. Any other way ?
Thanks

I'm importing data from a text file into SQL as a varchar, and I'm leaving it a varchar in its final destination table. It is essentially a price, i.e., $25.65. I'm using this price field (varchar) to perform a calculation...
Everything seems to work OK, but I'm not sure about using this varchar field to perform this calculation. Is this doable, or should it absolutely be converted to say, decimal?
Hi guys,
How do you convert a date varchar field which looks like 20080525 to 2008/05/25?
What's the maximum number of characters that varchar field will take? I read somewhere that it's 8k, but I may have misunderstood.
I have to potentially store 100k+ chars in a field.
What's the best way to do this?

I am setting up a database that will receive a lot of data from twoseparate telephone centers, the log table will in a short time haveover 1 million lines, and I was wondering if I should use 1 identifyfield or two:case 1:[Id] [int] IDENTITY (1, 1) NOT NULL[ServerId] [int] NOT NULLcase 2:[Id] [varchar(20)] IDENTITY NOT NULLWhere in case 1 I would just use a combination of Id and ServerId toidentify the line, where in case 2 I would have the Id field a varcharthat would look something like A-000001, A-000002 for server 1 andB-000001, B-000002 for server 2Which solution will be faster when searching for a record when thewill have over 1 million lines?

where [Year] = 2006
ORDER BY [Month]
Returns:
2006, 10
2006, 11
2006, 12

All other fields are updating ok and I'm not getting an error.I am trying to update a date and time (smalldatetime) using a stored procedure.First, the info to be updated comes from a datagrid.

Public Function updateData(ByVal sDate As DateTime, ByVal sp As String) 'Some items snipped for easier read
Dim command As SqlCommand = New SqlCommand(sp, conn) 'Where sp is the stored procdure name
command.Parameters.Add("@date", sDate)'And so on.....And then the stored procedure....@num VARCHAR(256),@date SMALLDATETIME,@contact VARCHAR(256),@notes VARCHAR(8000),@media VARCHAR(256) ASBEGIN DECLARE @errCode INT

-- UPDATE THE RECORDS UPDATE dbo.tblData SET fldDate = @date, fldContact = @contact, fldNotes = @notes, fldMedia = @media WHERE fldNum = @num
<sniped>Like I said, all other fields are updated with no problems, but not the date.The date format being passed into the sp is {0:MMM dd, yyyy hh:mm tt} or Aug 05, 2005 04:39 PM Is it the format of the date? Or something else I'm not seeing...Thanks all,Zath
