SQL Server 2012 :: Update Table From Variable Table Column?
Oct 6, 2014I am trying to use a stored procedure to update a column in a sql table using the value from a variable table I getting errors because my syntax is not correct. I think table aliases are not allowed in UPDATE statements.
This is my statement:
UPDATE [dbo].[sessions_teams] stc
SET stc.[Talks] = fmt.found_talks_type
FROM @Find_Missing_Talks fmt
WHERE stc.sessionid IN (SELECT sessionid FROM @Find_Missing_Talks)
AND stc.coupleid IN (SELECT coupleid FROM @Find_Missing_Talks)
Using A Variable To Specify Table Column In Sql Statement??
Feb 6, 2008Hello everyone,
I'm still quite new ASP.net, Visual Web Developer 2008, and SQL. It has been a fun learning experience so far. Anyways, the site I am designing needs to allow its users to extensively search several different databases (MS SQL databases). I have followed many of the tutorials and have found it rather easy to add table adapters, gridviews and other data features that use basic SQL Select statements. One of the major database tables contains several columns which I would like to include as a search parameters from a drop down list. I was wondering if there is any way I can write a select which will pass a variable to be used as a column name to the statement? For example:
SELECT DATE, GAME, EXACT, @COLNAMEFROM HistoryWHERE @COLNAME = @SOMEVARIABLE
This obviously doesnt work, but thats the gist of what I want to do. Any suggestions? I need this to be simple as possible, Most everything I'm doing is done through the visual design mode. Im still slow to learn C# and apply it in the codebehind files unless I have very detailed step by step instuctions.
Thanks

Restarting The Identity Column On Table Variable
Jun 2, 2006In a cursor, I declare a table variable like so:
DECLARE @TempTable TABLE(RowID INT IDENTITY, valueID int)
I then insert into that table from another table. The purpose is to get a list that looks like this after the insert:
RowID valueID1 348972 345223 94822
etc....
However, the next time through my loop (cursor) I want to restart my RowID identity property, because the next batch of valueID's should then again have a RowID starting from 1.
I tried
delete from @TempTable DBCC CHECKIDENT(@TempTable , RESEED, 0)
but I get 'Must declare the variable @TempTable table' error.
Is there a way to destroy and recreate that @TempTable variable?

Problem Referencing A Column In A Table Variable In A Query.
Apr 23, 2006Hello All
I have the following problem running an sp with a table variable (sql server 2000) - the error which occurs at the end of the query is: "must declare the variable @THeader" . @THeader is the name of the variable table and the error occurs with such references as @THeader.ApplyAmt, @THeader.TransactionHeaderID, etc.
declare @THeader TABLE (
TransactionHeaderID [int] NOT NULL ,
PatientID [int] NOT NULL ,
TransactionAllocationAmount [money] NOT NULL ,
ApplyAmt [money] NULL ) - create table variable
insert into @THeader select TransactionHeaderID,PatientID,TransactionAllocationAmount,ApplyAmt from mtblTransactionHeader where PatientID = 9 - fill the table variable
UPDATE @THeader
set TransactionAllocationAmount =
(SELECT isnull(Sum(mtblTransactionAllocation.Amount),0)
FROM mtblTransactionAllocation where mtblTransactionAllocation.DRID = TransactionHeaderID or
mtblTransactionAllocation.CRID = TransactionHeaderID) from @THeader, mtblTransactionAllocation - do the updates on the table variable
Update @THeader
set ApplyAmt = (SELECT mtblTransactionAllocation.Amount
FROM mtblTransactionAllocation where mtblTransactionAllocation.DRID = TransactionHeaderID and
mtblTransactionAllocation.CRID = 187 and PatientID = 9) from @THeader, mtblTransactionAllocation - do the updates on the table variable
- below is where the problems occur. It occurs with statements referencing columns in the table variable, i.e. @THeader.ApplyAmt
UPDATE mtblTransactionHeader
SET mtblTransactionHeader.TransactionAllocationAmount = @THeader.TransactionAllocationAmount,
mtblTransactionHeader.ApplyAmt = @THeader.ApplyAmt
FROM @THeader, mtblTransactionHeader
WHERE @THeader.TransactionHeaderID = mtblTransactionHeader.TransactionHeaderID - put the values back into original table
Thanks in advance

Random Selection From Table Variable In Subquery As A Column In Select Statement

Column As Variable
Jun 2, 2004I have a problem that I'm sure is very simple to answer for anyone that knows a bit of T-SQL. In a stored procedure, I simply want to concatenate a string variable containing a column name into a Select statement.
For example:
I want to execute the following statement but using a variable for the column name:
Select * from tblmet1araw where JulianDay = 1
JulianDay is an integer
This is how I have my code set up:
declare @xxx as varchar(20)
set @theday = 'JulianDay'
select * from tblmet1araw where @theday = 1
I get the following error:
Server: Msg 245, Level 16, State 1, Line 4
Syntax error converting the varchar value 'JulianDay' to a column of data type int.

Column Name As Variable
Oct 1, 2006Greetings,
I have a table that contains various columns in it totalling 12,000 rows of data. For example;
site_ref, account_title, gl_code, period1, period2, period3 etc through to period12
I wish to write a query that will allow me to search for specific site_ref, acount_title etc and then only one of the period columns. This period column will be specified by the user at the time of submitting the query through reporting services. How do I assign a column to a variable so that the user can set it in the report parameters and then the code will run against that specific column for the period?
Example would be to see everything for site_ref = 'tb', account_title = 'gross rent' and the financial figures within the column titled 'period10' or the next time they run the report they may wish to run it against the values in period7.
Any pointers would be appreciated

Using A Variable For A Column Name In A Query
Sep 22, 2006Is it possible to use a column name variable in a Select Statement for a column name?For example I have a dropdown with FName,LName,Phone and a text box. The user can select the field to search and the criteria will go into the text box. The problem is the select doesn't like a variable for the field name. I have tried both a standard variable and a Case statement (see below). This is being used in a Stored Procedure with MSSQL. The actual select is much more complicated than this but it gets the point across. Thanks for your help in advance@Field as varchar( 50),@Value as varchar (50)SELECT *FROM customersWHERE @Field = @ValueORSELECT *FROM customersWHERE CASE WHEN @Field = 'Fname' THEN Fname = @Value END, CASE WHEN @Field = 'Lname' THEN Lname = @Value END, CASE WHEN @Field = 'Phone' THEN Phone = @Value END;

The problem is using a variable in place of a column name I can not get the data to return, only the column name.
-- Here is how I get the column name. It works great, @CName
-- reflects the column name as I use it elsewhere fine.
