Using A Variable For Tablename In Select Statement?

Sep 19, 2007

I have a stored procedure that accepts the table name as a parameter. Is there anyway I can use this variable in my select statement after the 'from' clause. ie "select count(*) from @Table_Name"?

When I try that is says "Must declare the table variable @Table_Name". Thanks!

Using Cursor Variable As A Tablename

Oct 12, 2005

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?

Aug 28, 2007

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?

Apr 16, 2008

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

Dec 28, 2004

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 ?

Is it possible to add a variable in SSIS like

Return Variable Name As Part Of Select Statement.

Mar 9, 2008

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

Apr 24, 2007

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

if you are run
select * from

sysobjects where name like 'aa%') insqlhelp2

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

please help me thanks for all

Combing In A Cursor, A Select Statement With The WHERE Clause Stored In A Variable

Mar 28, 2000

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

Transact SQL :: How To Turn Select Aggregate Function Statement Into A Variable

May 26, 2015

I tend to learn from example and am used to powershell. If for instance in powershell I wanted to get-something and store it in a variable I could, then use it again in the same code. In this example of a table order items where there are order_num, quantity and item_prices how could I declare ordertotal as a variable then instead of repeating it again at "having sum", instead use the variable in its place?

Any example of such a use of a variable that still lets me select the order_num, ordertotal and group them etc? I hope to simply replace in the "having section" the agg function with "ordertotal" which bombs out.

select order_num, sum(quantity*item_price) as ordertotal
from orderitems
group by order_num
having sum(quantity*item_price) >=50
order by ordertotal;

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

Nov 7, 2007

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)

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.
If I write a simple command : Cmd = SELECT PartNumber, PartName, PartsAvailable FROM Inventory WHERE PartNumber = "P7226" , the command is executed but the return data falls on the floor somewhere as I dont know how to code to put the results in an array or in fact, have any idea on how to find the returned data. Can anyone help with this simple(?) problem?  My sub that handles the sql command is shown below.
I have also been looking for the way to code in VB to cause existing controls like GridViews to access, edit, and insert but I havent been able to find a paper or tutorial. If anyone has seen this information, it would be helpful also.Protected Sub CallSQL(ByVal Cmd As String)
Dim conn As New SqlConnection("Data Source=.SQLExpress;AttachDbFileName=C:Documents and SettingsaMy DocumentsVisual Studio 2005WebSitesWebSite5App_DataPINEMgt.mdf; Integrated Security=True;Connect Timeout=30;User Instance=True") 'Data Source=.SQLEXPRESS;AttachDbFilename="C:Documents and SettingsaMy DocumentsVisual Studio 2005WebSitesWebSite5App_DataPINEMgt.mdf";Integrated Security=True;Connect Timeout=30;User Instance=True)Dim sql As String = String.Empty
sql = Cmd
'Open the connection to the database and execute he SQL
conn.Open()Dim command As New SqlCommand(sql, conn)
command.ExecuteNonQuery()
conn.Close()
End Sub

Hello... im having a problem with my query optimization....

I have a query that looks like this:


SELECT * FROM table1
WHERE location_id IN (SELECT location_id from location_table WHERE account_id = 998)


it produces my desired data but it takes 3 minutes to run the query... is there any way to make this faster?... thank you so much...
