I'm curious if anyone knows the correct way to do this pseudo-statement correctly? I want to create a stored procedure in which I send it the table name of the table I want to query.declare @tableName varchar(500)set @tableName = 'PortfolioPreferenceOwnership' select * from @tableName
View 4 RepliesHi,I'm trying to dynamically assign the table name for a SELECT statement but can't get it to work. Given below is my code: SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

CREATE PROCEDURE GetLastProjectNumber (@DeptCode varchar(20))
AS
BEGIN TRANSACTION
SET NOCOUNT ON
DECLARE @ProjectNumber int
SET @ProjectNumber = 'ProjectNumber' + REPLACE(CONVERT(char,@DeptCode),'.','')
SELECT MAX(@ProjectNumber)
FROM 'tbl_ProjectNumber' + REPLACE(CONVERT(char,@DeptCode),'.','');
END TRANSACTION Basically, I have a bunch of tables which were created dynamically using the code from this post and now I need to access the last row in a table that matches the supplied DeptCode. This is the error I get:Msg 102, Level 15, State 1, Procedure GetLastProjectNumber, Line 29Incorrect syntax near 'tbl_ProjectNumber'. Any help would be appreciated.Thanks.
Hello 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
Scott
I am running SQL Server 2000 and need to know how to write an IF else statement with a variable for a table name. I am constantly getting errors when I attempt this feat.
Code:
Use [TestDatabase]
Go
CREATE PROCEDURE UserInputAsTable
[code]....
Is it possible to have part of a table name used in a CREATE statementcontained in a variable? Here's what I'd like to do, althoughobviously the syntax of this isn't quite right or I wouldn't be hereasking:DECLARE @TblPrefix char (3)SET @TblPrefix = 'tst'CREATE TABLE @TblPrefix + TestTable (col1 int)The point there is to have a table named tstTestTableThe reason I need to do this is that my ISP will only give me onedatabase to work with and I'd like to have two copies of theapplication I'm developing running at the same time. So I'd like torun the sql script that creates the tables with TblPrefix set to "dev"and then run it again with TblPrefix set to "liv"thankseric

I've used a temporary table in the stored procedure
I've created it as DECLARE @Temp TABLE (id INT)
in select clause I've used this temp table through the joins..
But I've also used a varchar variable to store my criteria...
which I'm building in the stored procedure
so inorder to use it in the where clause I used
EXEC ('SELECT ....................
FROM @Temp T
LEFT OUTER JOIN ...
LEFT OUTER JOIN ...
WHERE ' + @Criteria )
Unfortunately this is not working.
Giving the errror
Must declare the variable '@TempT'.
I had to use Temporary table using #, which I feel is really waste of memory...
Is there a way by which I can use my Table variable in the EXEC statement.
Thanks In advance
Consider the below code: I am trying to find a way so that my select statement (which will actually be used to insert records) can randomly place values in the Source and Type columns that it selects from a list which in this case is records in a table variable. I dont really want to perform the insert inside a loop since the production version will work with millions of records. Anyone have any suggestions of how to change the subqueries that constitute these columns so that they are randomized?
SET NOCOUNT ON
Declare @RandomRecordCount as int, @Counter as int
Select @RandomRecordCount = 1000
Declare @Type table (Name nvarchar(200) NOT NULL)
Declare @Source table (Name nvarchar(200) NOT NULL)
Declare @Users table (Name nvarchar(200) NOT NULL)
Declare @NumericBase table (Number int not null)
Set @Counter = 0
while @Counter < @RandomRecordCount
begin
Insert into @NumericBase(Number)Values(@Counter)
set @Counter = @Counter + 1
end
Insert into @Type(Name)
Select 'Type: Buick' UNION ALL
Select 'Type: Cadillac' UNION ALL
Select 'Type: Chevrolet' UNION ALL
Select 'Type: GMC'
Insert into @Source(Name)
Select 'Source: Japan' UNION ALL
Select 'Source: China' UNION ALL
Select 'Source: Spain' UNION ALL
Select 'Source: India' UNION ALL
Select 'Source: USA'
Insert into @Users(Name)
Select 'keith' UNION ALL
Select 'kevin' UNION ALL
Select 'chris' UNION ALL
Select 'chad' UNION ALL
Select 'brian'
select

I have a parameter which should take multiple values into it and pass that to the code that i use. For, this i created a parameter and temporarily for testing i am passing some values into it.Using a dynamic SQL i am converting multiple values into multiple records as rows into another variable (called @QUERY). My question is, how to insert the values from variable into a table (table variable or temp table or CTE).OR Is there any way to parse the multiple values into a table. like if we pass multiple values into a parameter. those should go into a table as rows.
Greetings everyone,
I am trying to use a c# string with an SQL statement in a data adapter (.NET 03)
The code works fine and I have a variable called : string test = ..... that takes the needed values. I just need to implement this string in the sql statement. I tried adding this to my query but I only got an empty row:
WHERE (login = '" & test & "')
WHERE (login = '" + test + "')
any ideas?
PS: If I change to something like WHERE (login = 'abcdef') I get a result meaning there's something wrong with the way I am putting the variable in the sql query.
Again, I am not putting the string in a normal query in my .cs code. this is happening by right clicking the data adapter and configuring the sql statement in the designer window
THANKS!
Hi,
I've created an sql statement:
select *
from fin_installment
where key_construction = (select ser_construction from fin_construction where key_contract = ' " & variable & " ') order by int_serial
which is in an Dataset's TableAdapter.
This variable receives its value during the form init and it is an integer.
When I start the page the folowing error message is displayed:
" An error has occurred during report processing.
Exception has been thrown by the target of an invocation.
Conversion failed when converting the varchar value ' " & azonosito & " ' to data type int. "
So my question is that how can I use variables in sql statement in dataset?
Hi, I am trying to use a variable inside a LIKE statement, but it is not working as expected. It will not give a error, but it shows no results while it does show results if I replace the variable with the normal string within the LIKE statement. Here is my code:
Code:
-- this example returns results
SELECT whatever
FROM mytable
WHERE whatever LIKE 'blah%';
Code:
-- this example returns no results
DECLARE @test VARCHAR;
SET @test='blah%';
SELECT whatever
FROM mytable
WHERE whatever LIKE @test;
Any ideas why the version using the variable would not work?

I'm having some trouble modifing a script to save me tons of work. The script if from Microsoft, and it is used as step 3 in a 6 step process to move MS Great Plains users from one server to another. Anyway, the script runs on only 1 company database at a time, and for most Great Plains environments there would only be 1 or 2 company DBs. But I am administering in an ASP environment and we have over 30 company DBs to move. So, I though I would adapt thier script to iterate over each company DB to do the work (rather than creating 30 separate scripts). So I wrapped their loop with my loop to do the iteration. The problem is that T-SQL will not let me use a variable in a USE statement. I've tried to remove the USE statements, but that added a lot of complexity in the internal loop. What is the best way to do this?
Here is the modified code:
/*
** Drop_Users_Company.sql
**
** This script will remove all users from the DYNGRP in the company database
** specified. It will then drop the DYNGRP and readd the DYNGRP to the company.
** It will then add all users back to the DYNGRP based on the SY60100 table.
** NOTE: You will need to replace %Companydb% with the company database
** name.
*/
/* Instead of replacing %Companydb% (in each USE statement) with the name of the
single company database that this script is supposed to work on, I've added
@cCompany to hold the company DB name through each iteration of the outside
cursor/while loop.
*/
declare @cCompany sysname/* ADDED BY ME FOR THE OUTSIDE LOOP */
declare @cStatement varchar(255)/* Misc exec string */
declare @DynDB varchar(15)/* DB Name exec string */
declare @DYNGRPgid int/* Id of DYNGRP group */
/*
** Loop through all company databases, emptying the DYNGRP group.
*/
SET QUOTED_IDENTIFIER OFF
use DYNAMICS
/* Select all of the Great Plains database names from the DB_Upgrade table, where the DB names are conviently stored */
declare C_cursor CURSOR for select db_name from DYNAMICS..DB_Upgrade where db_name not in ('DYNAMICS')
OPEN C_cursor
FETCH NEXT FROM C_cursor INTO @cCompany
WHILE (@@FETCH_STATUS <> -1)
begin
use @cCompany
select @DYNGRPgid = (select gid from sysusers where name = 'DYNGRP')
declare G_cursor CURSOR for select "sp_dropuser [" + name+"]" from sysusers
where gid = @DYNGRPgid and name <> 'DYNGRP'
set nocount on
OPEN G_cursor
FETCH NEXT FROM G_cursor INTO @cStatement
WHILE (@@FETCH_STATUS <> -1)
begin
EXEC (@cStatement)
FETCH NEXT FROM G_cursor INTO @cStatement
end
DEALLOCATE G_cursor
/*
** Do not delete the group to attempt to preserve the permissions already
** granted to it.
*/
use @cCompany
if exists (select gid from sysusers where name = 'DYNGRP')
begin
exec sp_dropgroup DYNGRP
end
/*
** Recreate the DYNGRP group in all company databases.
*/
use @cCompany
if not exists (select name from sysusers where name = 'DYNGRP')
begin
exec ("sp_addgroup DYNGRP")
end
end

I wanted to pass a SQL statement thru a variable, and use that variable in my source component.
SELECT CLINIC_SUK, CLINIC_CODE, CLINIC_DESC, CLINIC_ARABIC, Load_DT

Hi ,
I am testing a very simple query that use variable for sort direction and sort expression
DECLARE
@SortExp nvarchar(256),
@SortDir nvarchar(10)
Set @SortExp = 'curTime'
Set @SortDir = 'DESC'
Select * from table
where recID < 20
order by @SortExp @SortDir
and i got this error...
The SELECT item identified by the ORDER BY number 1 contains a variable as part of the expression identifying a column position. Variables are only allowed when ordering by an expression referencing a column name.
Is there anyway to do this task.

Hy, i have this problem in vb.net:
I must use a variable in SQL UPDATE statement, after SET statement, and i'm getting error. This is that line of code:
Dim variable_name As StringDim variable As Integer
Dim sqlString As String = ("UPDATE table_name SET " variable_name " = " & variable & " WHERE UserID = '" & UserID & "'")Dim cmdSqlCommand As New SqlCommand(sqlString, conConnetion)
cmdSqlCommand.ExecuteNonQuery()
When I don't use a variable after SET statement, everything work fine. This code works fine:
Dim variable As Integer
Dim sqlString As String = ("UPDATE table_name SET column_name = " & variable & " WHERE UserID = '" & UserID & "'")Dim cmdSqlCommand As New SqlCommand(sqlString, conConnetion)
cmdSqlCommand.ExecuteNonQuery()
Please, if someone can help me in this...thanks..
could anyone please help me to resolve this issue?
here's my sql query which retrieve last 3 month data
t.execute(SELECT * tbl1 where nmonth >= datepart(mm,DATEADD(month, -3, getdate())) or nmonth <=datepart(mm,getdate()) and empno='"+emppip+"'")
now instead of passing 3 in this query(datepart(mm,DATEADD(month, -3, getdate())) )
i need to pass a variable to retrieve data based on user requirements.
i tried this way,
dim mno as n
mno=4
t.execute(SELECT * tbl1 where nmonth >= datepart(mm,DATEADD(month, -'"+mno+"', getdate())) or nmonth <=datepart(mm,getdate()) and empno='"+emppip+"'")

can i achieve this using stored procedure? or can i directly pass a variable to sql synatax?

I am having difficulties with some sql syntax with sql server 2000.
I am trying to write code to update a column in which the name of it is unknown. At run time, I am able to set a variable equal to the correct column name but in doing so, treats the value as a String.
Ex.
Declare @varA varchar(12)
select @varA = (select top 1 Value from #temp)
Update TableX
set @varA = y.ColTest
from TableX x, TableY y
where x.Colid = y.Colid
It sets the variable = to the last value from TableX.ColTest
I want the Update statement to update the value for the Variable which
represents the correct column to update.
Any ideas?
Thanks,
Daniel

--Open and perform initial fetch
open curdb
fetch curdb into @DataBase

Hello,
I would like to set a variable within my if exists statement, however SQL is throwing and error stating:
Incorrect syntax near '='.
If I remove the if exists, the query runs fine. Is there a reason why this is not working the way I have it and what suggestions can I use to accomplish what I am trying to do, which is store the ID into the permissionID variable
Here is my code block:
Code Snippet
declare @permissionID int;
if exists(select @permissionID = Id from Permission
where [Description] = 'SettlementReport')

I've been coding a few years and SSIS makes me feel more stupid than any program I've ever used.
I've read BOL and bought a book. Can't say either one has really helped.
I'm still a complete idiot after one week of working with it. I apologize for asking so many stupid questions.
What I'm trying to do now is parameterize a SQL statement.
I have a variable that's a string. I have a DataFlowComponent as a data source. I find references all over the Internet and this forum to something called an "ExecuteSQLTask" but I sure can't figure out what that is. In my toolbox I have data flow sources for DataReader, Excel, Flat Files, Old DB, Raw file, and XML but no Execute Sql Task.
Anyway SELECT * FROM TABLE WHERE COLUMN='Value' in the SQL Command property is simple enough. Now I want 'Value' to be a variable. You know, like in T/SQL DECLARE @Foo VarChar(25). Creating the variable is easy as pie.
I have found at least 10 different examples of specifying variables on the web, all of which claim to be SSIS examples, Is it User::Variable? @[User::Variable]? @Variable?
I want to read rows from a table, with a a variable value in the WHERE clause, and pass them to the fuzzy lookup task.
Is my approach fundamentally flawed in some way?
Hi Experts, I would like to make a stored procedure in my db: I have sql express 2005.
I get Error 164 when creating this procedure:
CREATE PROCEDURE CrossTable
@Variable1 smallint,
@Variable2 smallint,
@Value smallint
AS
BEGIN
SELECT @Variable1, COUNT(@Variable1) AS 'Haufigkeiten'
FROM SurveyData
WHERE @Variable2 = @Value
GROUP BY @Variable1
END
GO
I would like to generate a frequency chart per userdefined-variable (@variable) with a where restriction.
The GROUP BY @Variable1 seems to be problem: is there some workaround in order to use variables in a GROUP BY clause? or how can I write an sql statement which do the same as this procedure (CrossTable) without using the GROUP BY clause?
Thanks a lot for your replies
