MS SQL Server :: Using A Variable For Tablename In Select Statement?

Cannot Set A Variable From A Select Statement That Contains A Variable??? Help Please
I am trying to set a vaiable from a select statement

DECLARE @VALUE_KEEP NVARCHAR(120),

@COLUMN_NAME NVARCHAR(120)

SET @COLUMN_NAME = (SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'CONTACTS' AND COLUMN_NAME = 'FIRSTNAME')

SET @VALUE_KEEP = (SELECT @COLUMN_NAME FROM CONTACTS WHERE CONTACT_ID = 3)

PRINT @VALUE_KEEP

PRINT @COLUMN_NAME

RESULTS

-------------------------------------------------------------------------------------------

FirstName <-----------@VALUE_KEEP

FirstName <-----------@COLUMN_NAME

SELECT @COLUMN_NAME FROM CONTACTS returns: FirstName

SELECT FirstName from Contacts returns: Brent

How do I make this select statement work using the @COLUMN_NAME variable?

Any help greatly appreciated!

Using Cursor Variable As A Tablename
I am currently using a cursor to scroll through sysobjects to extract table names and then extracting relevant column names from syscolumns.

I then need to run the following script:

declare Detail_Cursor cursor for
select @colname, max(len(@colname)) from @table

The message I receive is "must declare variable @table".

Immediately prior to this script I printed out the result of @table which works fine so the variable obviously is declared and populated.

Can anyone let me know what I'm doing wrong or how I can get the same result.

Thanks

How Can You Use A Variable Tablename And Retrieve The Output From The Insert?
We are trying to create a unique key from a table with indentity set in the table. We will have a number of these tables. Therefore, we will be creating a stored procedure and passing the table as a parameter. In this example we are setting the table.

When we run the the script, the output clause from the insert should give us a unique number from the given table in the temporary table. This example stores the output in a temporary table @tTemp.

How can you use a variable table name and retrieve the output from the Insert?

declare @tTestTable varchar (20)

set @tTestTable = 'mis.test_sequence'

--DECLARE @tTestTable TABLE ( sqVal [int] IDENTITY(1,1) NOT NULL, add_date datetime)
declare @testsql varchar (4000), @testseq int

DECLARE @tTemp table (mainpk int)

set @testsql = 'DECLARE @tTemp table (mainpk int) INSERT ' + @tTestTable + ' OUTPUT INSERTED.sqVal into @tTemp VALUES (getdate() ) SELECT @testseq=mainpk FROM @tTemp'

select @testsql

EXECUTE sp_executesql @testsql, N'@testseq int output,@tTemp table (mainpk int),@tTemp table (mainpk int) ',@tTemp,@tTemp,@testseq output,@tTemp

SELECT * FROM @tTemp

Please help
Thanks Tim.

SQL Select Statement With A 'string' Variable?
I'm trying to add a 'change password' control to my site and seem to be having some issues. I have code that works if I statically define what user is displayed on the form, but I cant get it to detect the 'authenticated' user and show them the reset for for that ID.If I take the "+ myid" out of the select statement and just define the username statically the form works properly. Error:System.Data.SqlClient.SqlException: The column prefix
'System.Security.Principal' does not match with a table name or alias name used
in the query. Here's a piece of the code that is supposed to detect the current logged in user. However, it gives the error. (some of the code may be redundant but its not causing issues that I can tell) public void InitPage() { IPrincipal p = HttpContext.Current.User; String myid = HttpContext.Current.User.ToString(); SqlServer sqlServer = new SqlServer(Util.SqlConnectionString()); DataTable dt; SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings["myconnection"].ConnectionString); SqlDataAdapter cmd1 = new SqlDataAdapter("select * from USER WHERE USER_NAME = "+ myid, cnn); DataTable UIDtable = new DataTable(); cmd1.Fill(UIDtable); User_Id.Value = UIDtable.Rows[0]["ID"].ToString(); dt = sqlServer.USER_SELECT(Util.SiteURL(Request.QueryString["Pg"].ToString()), User_Id.Value);

Use A Variable Along With The FROM Clause In SELECT Statement
I have a table 'table_list' which contains two columns, table_name and a record_count. This table stores a list of tables and their corresponding record counts.

What I am trying to do is, to be able to write a select statement, that can read each table name in the 'table_name' column, execute a select count(*) for the same, and update its record_count with the result of select count(*).

This is the code in my procedure..

DECLARE @tab_list CURSOR
set @tab_list = CURSOR FOR select * from table_list
OPEN @tab_list

DECLARE @tab_name varchar(256)
DECLARE @rec_cnt int
FETCH NEXT FROM @tab_list INTO @tab_name, @rec_cnt

select count(*) from @tab_name

This select is looping around along with FETCH till all the table names are exhausted and their counts are updated from the cursor back into the table.

Problem is that, I am not able to use select count(*) from @tab_name, and its not accepting a variable there.

Please help me to construct the select statement that is similiar to

x=<table name>
select * from x
where x is a variable and the table name gets substituted.

what is the syntax for it ?

Return Variable Name As Part Of Select Statement.
hey all,

I have the following query:

ALTER PROCEDURE [dbo].[sp_SelectMostRecentArticle]

AS
BEGIN

DECLARE @article_id INT
SELECT @article_id = (
SELECT TOP 1 article_id
FROM article
ORDER BY article_id DESC
)

DECLARE @comment_count INT
SELECT @comment_count = (
SELECT COUNT(comment_id)
FROM comment
JOIN article ON article_id = comment_article_id
GROUP BY article_id
HAVING article_id = @article_id
)

SELECT TOP 1 article_id, article_author_id,
article_title, article_body, article_post_date,
article_edit_date, article_status, article_author_id
article_author_ip, author_display_name,
category_id, category_name--, comment_count AS @comment_count

FROM article

JOIN author ON author_id = article_author_id
JOIN category ON category_id = article_category_id

GROUP BY article_id, article_title, article_body, article_post_date,
article_edit_date, article_status, article_author_ip,article_author_id,
author_display_name, category_id, category_name

HAVING article_id = @article_id

END
GO

as you can see, im trying to return a comment_count value, but the only way I can do this is by defining the variable.

I have had to do it this way, because I cannot say COUNT(comment.comment_id) AS comment_count or it returns an error that it cant reference the comment.comment_id.

But when change it to FROM article, comment; I get errors about the article_author_id and article_comment_id.

And i cant add a join, because it would return the amount of rows of the comment...

unless someone could help with what i Just decribed (as i would prefer to do it this way), how would i return the variable value as part of the select statement?

Cheers

Unable To Create Variable Select Statement In For Each Loop
What I'm trying to do is this;

I have a table with Year , Account and Amount as fields. I want to

SELECT Year, Account, sum(Amount) AS Amt

FROM GLTable

WHERE Year <= varYear

varYear being a variable which is each year from a query

SELECT Distinct Year FROM GLTable

My thought was that I would need to pass a variable into a select statement which then would be used as the source in my Data Flow Task.

What I have done is to defined two variables as follows

Name: varYear (this will hold the year)

Scope: Package

Data type: String

Name:vSQL (This will hold a SQL statement using the varYear)

Scope: Package

Data type: String

Value: "SELECT Year, Account, sum(Amount) AS Amount FROM GLTable WHERE Year <=" + @[User::varYear]

I've created a SQL Task as follows

Result set: Full Result Set

Connection Type: OLE DB

SQL Statement: SELECT DISTINCT Year FROM GLTable

Result Name: 0

Variable Name: User::varYear

Next I created a For Each Loop container with the following parameters

Enumerator: Foreach ADO Enumerator

ADO Object source Variable: User::varYear

Enumeration Mode: Rows in First Table

I then created a Data Flow Task in the Foreach Loop Container and as the source used OLE DB Source as follows

Data Access Mode: SQL Command from Variable

Variable Name: User::varYear

However this returns a couple of errors "Statement(s) could not be prepared."

and "Incorrect syntax near '='.".

I'm not sure what is wrong or if this is the right way to accomplish what I am trying to do. I got this from another thread "Passing Variables" started 15 Nov 2005.

Any help would be most appreciated.

Regards,

Bill

Combing In A Cursor, A Select Statement With The WHERE Clause Stored In A Variable
Hi
I am ramesh here from go-events.com
I am using sql mail to send out emails to my mailing list

I have difficulty combining a select statement with a where clause stored in a variable inside a cursor

The users select the mail content and frequency of delivery and i deliver the mail

I use lots of queries and a stored procedure to retrieve thier preferences. In the end i use a cursor to send out mails to each of them.

Because my query is dynamic, the where clause of my select statement is stored in a variable. I have the following code
that does not work

For example

DECLARE overdue3 CURSOR
LOCAL FORWARD_ONLY
FOR SELECT DISTINCT Events.E_Name, Events.E_SDate, Events.E_City, Events.E_ID FROM Events, IndustryEvents + @sqlquery2
OPEN overdue3

I get an error message at the '+' sign
which says, cannot use empty object or column names, use a single
space if necessary

How do I combine the select statement with the where clause?

Help me...I need help urgently

this query return:

Invalid column name 'id_no'.

this error returned because max(id_no) column is absent

if you are run
select * from
(select max(name) insqlhelp from

this query return that

insqlhelp ---------------
aaa2

(1 row(s) affected)

this mean that my table name query returned table name but i cant use this name in any other query (i think because of daclaring alias "insqlhelp, insqlhelp2")

other way is

set to any other text variable to table name,
and concetanate to query,
and execute with exec

but in this way you cant set to my int variable

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

I am learing VWD as I build a site and while I can use the various controls (GridView, FormView) to set up operations and retrieve/display database information, I need to be able to codebehind to do SQL operations for retrieving data to fill paper forms and to modify the database. After I retrieve data from the database, I need to do a lot of computation befor I build a paper quote that is emailed to a customer. I have written a subroutine to which I pass my sql query statement and I can add a new entry and edit an existing entry. The problem is a simple query to read an existing database entry.

Multiple Tables Used In Select Statement Makes My Update Statement Not Work?
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

Because other reasons. I need to modify that query to:

Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
INTO AuxiliaryTable
FROM myTables
WHERE Conditions are true
ORDER BY Field01
SELECT DISTINCT [Field02] FROM AuxTable
The the results are:

Field02

----------------------

22810
8461760

And what I need is (without showing any other field):

Field02

----------------------

8461760
22810

Is there any good suggestion?
Thanks in advance for any help,
Aldo.

Using C# Variable With SQL Statement
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!

Variable In An Sql Statement
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?

USE Statement With A Variable?
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
DEALLOCATE C_cursor

Using Variable In LIKE Statement
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?

SQL Statement With Variable.
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.

Thanks

SQL Statement In Variable
Hello Everyone,
                           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
FROM         DIM_CLINIC
where load_dt > ?

I had created a variable with my SQL statement and mapped that variable in my source component.
Its giving me some error.

Parameter Information cannot be derived from SQL statement. Set parameter information before preparing command.

Please do inform me about the solution for having a parameter in my source SQL Statement.

Declaring A Table Variable Within A Select Table Joined To Other Select Tables In Query
Hello,

I hope someone can answer this, I'm not even sure where to start looking for documentation on this. The SQL query I'm referencing is included at the bottom of this post.

I have a query with 3 select statements joined together like tables. It works great, except for the fact that I need to declare a variable and make it a table within two of those 3. The example is below. You'll see that I have three select statements made into tables A, B, and C, and that table A has a variable @years, which is a table.

This works when I just run table A by itself, but when I execute the entire query, I get an error about the "declare" keyword, and then some other errors near the word "as" and the ")" character. These are some of those errors that I find pretty meaningless that just mean I've really thrown something off.

So, am I not allowed to declare a variable within these SELECT tables that I'm creating and joining?

Thanks in advance,
Andy

Select * from

(

declare @years table (years int);

insert into @years

select

CASE

WHEN month(getdate()) in (1) THEN year(getdate())-1

WHEN month(getdate()) in (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) THEN year(getdate())

END

select

u.fullname

, sum(tx.Dm_Time) LastMonthBillhours

, sum(tx.Dm_Time)/((select dm_billabledays from dm_billabledays where Dm_Month = Month(GetDate()))*8) lasmosbillingpercentage

(tx.owninguser = u.systemuserid)

where

Month(tx.Dm_Date) = Month(getdate())-1

and tx.dm_billable = 1

group by u.fullname

Using A Variable For Tablename In Select Statement?
