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!

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

I'm relatively new to SQL, and I'm trying to write some procedure.. but this wasn't working.. :(
I tried to make several smaller tables from one big table based on some value of one of the column. Here's my procedure:
USE WAREHOUSE
DECLARE
@COUNTER NUMERIC,
@TBLTTL CHAR(11)
SELECT @COUNTER = 1
WHILE (@COUNTER <40)
BEGIN
SET @TBLTTL= 'Inventory' + CAST(@COUNTER AS char(2))
SELECT *
INTO @TBLTTL <== *error refers to this line*
FROM MAIN
WHERE invtype=@COUNTER
SELECT @COUNTER = @COUNTER +1
END
The error message that I got was:
Incorrect syntax near '@TBLTTL' (look at * above)
What should I do if I want to create a loop which would create (or later update) new smaller tables automatically? Any suggestions are welcomed.
Thx,
Ferdinand.

I believe this is quite elementary but here goes
can you run a query like
SELECT * from Table where Item IN @variable
where @ variable is a varchar containing a list of items in quotes,seperated by a comma
THANKS

Hi,
I am writing a sproc that has simple search functionality, basically if someone selects ALL, then the sql should be the following
IF(@grade = 'ALL')BEGIN SET @gradeChoice = '1,2,3,4,5' END
ELSE BEGIN SET @gradeChoice = @grade END
Then i have
SELECT * from table where grade IN @gradeChoice
It doesnt seem to work as normal. I thought it would work the same with a variable?
Thanks for any help

I just want to get the sum of a table's column into a variable, in a stored procedure. The best I can do is
SET @TotalBalance = SELECT SUM(Balance) FROM AccountDetails
Not good enough, of course.

Hi,
I am trying to get the login name of a user, trim off some characters, which works fine, convert this to a string variable, which works fine and then use this variable in an sql select parameter.
I've tried countless things and am not sure why my variable @NewString is not working in the Select command. If I add a default value I know is present, it works, but it can't seem to pick up the variable value of NewString. It prints out as expected in the response.write statement, but I really need it to connect to the corresponding value in the database.
Any ideas are greatly appreciated-code below.
Thanks,
Liz

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);

I'm still having a problem getting a select statement to work. I have posted the script on a web site, along with the table definitions, and sample output at the bottom. The problem is when I set @total_debits, I get 0 instead of 11580.95. I think the problem is that the format of the @end_date or the @balance_date is the problem. Please take a look at it. I posted a question on Friday about this, and tried to give a "snippet" and mistyped it. So here it is. Please give me all feed back.

I'm trying to build a select statement for a CURSOR where part of the SQL statement is built using a variable.
The following fails to parse:
Declare Cursor1 Cursor
For
'select table_name from ' + @database + '.Information_Schema.Tables Where Table_Type = ''Base Table'' order by Table_Name'
Open cursor1
That doesn't work, I've also tried using an Execute() statement, no luck there either. Any ideas or suggestions are greatly appreciated.

I want to be able to have a single select statment:
SELECT TOP 1 Call.JobNum, Call.CallID, Call.Company, Call.LastCallTime
FROM ClientJob INNER JOIN Client ON ClientJob.ClientID = Client.ClientID
INNER JOIN Call INNER JOIN Login ON Call.JobNum = Login.JobNum ON ClientJob.JobNum = Login.JobNum
WHERE (Login.LoginID = 3) AND (Call.Status = 0) AND (DATEDIFF(hh, Call.LastCallTime, getdate()) > 10)
ORDER BY Call.CallID
but with this select statment I also want to set a variable:
declare @variable int
SELECT TOP 1 Call.JobNum, @variable = Call.CallID, Call.Company, Call.LastCallTime
FROM ClientJob INNER JOIN Client ON ClientJob.ClientID = Client.ClientID
INNER JOIN Call INNER JOIN Login ON Call.JobNum = Login.JobNum ON ClientJob.JobNum = Login.JobNum
WHERE (Login.LoginID = 3) AND (Call.Status = 0) AND (DATEDIFF(hh, Call.LastCallTime, getdate()) > 10)
ORDER BY Call.CallID
Now SQL Server does not like this, can not set a variable in a multiple select statment. I NEED to do this all in one step if possible. Any suggestions?

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 ?

I can't seem to get a cursor to work when I'm passing in a variable for a column name of the select statement. For example:
declare @col varchar(50)
set @col = 'Temperature'
declare notifycurs cursor scroll for
select @col from Table
Obviously this won't work correctly (since the result will simply be 'Temperature' instead of the actual float value for temperature). I tried to use quotes for the entire statement with an EXEC
(ie. exec('select '+@col+' from Table' )
but that gave me an error.
Is there a way to pass in a variable for a column name for a curor select statement????

Hi this is probably a very stupid question, but I still need to know.
How do I set the result of a 'SELECT' statement to a variable? I know I can use CURSOR, but I am certain the SELECT statement will return either 1 record or NULL. Can I use something else apart from CURSOR?

Hi all
Imagine we have a table as follow:
Create Table Test(
Pkey int not Null identity Primary Key,
Name varchar(20) not null,
Famil varchar(30) not null
)
now is there anyway to Run following Script:
declare @FLDName varchar(10)
set @FLDName='Name'
Select @FLDName from Test
in the other hand is there anyway to use Local variables in a SELECT statements as above?
to tell you the truth , what really motivated me to do this , was being able to declare a User-Defined-Function and passing some fields as an String and then use them in a SELECT statement or any other T-Sql codes!!!
Could anyone help me.?
Kind Regards.
