Why does this not work.....SQL
Declare @MyParam varchar (20)
Set @MyParam = 'MyTableName'
Select * from @MyParam
Seems obvious that it should, is it all TEMP TABLES needed.
|
|
|
|
|
Where exactly are you defining a temporary table in this example?
|
|
|
|

Hi, I'm not.
Just want to use a variable to access an exisiting table.
Select * from @parameter
is this not possible?
Thanks for the interest
|

ASAIK, you can only create a table[^] variable, fill it with data and then use in SELECT statements.

have the sql query in a string variable and execute using sp_executesql or EXECUTE Command. something like this should work, try...
@SqlQuery = 'Select * from ' + @MyParam<br />
EXEC sp_executesql @SqlQuery

You should always enclosed the table name in side square brackets just in case it contains any odd characters and the table name should be checked to see if the table exists first. These are very basic security precautions against invalid or maliceous data from causing problems with the database.

hi there, in this example you didn't create any table. You creating a variable and it is not possible to select from variable,
--
Declare @MyParam varchar (20)
Set @MyParam = 'MyTableName'
you can simple select like this:
SELECT @MyParam
-- it will give this result 'MyTableName'
if you want to create table, use this
Create Table #MyTableName
(
here you define the attributes
ex.
atributename varchar(20)
)
and then you can use
SELECT * FROM #MyTableName
the result --- atributename
respect

Cheers guys, job done via Dynamic SQL.
Why I can't lookup a variable table name, who knows? Seems stupid to not be able to.
Thanks again.

Because it's not part of the language specification.

Hi,
How can I add a new column in middle/(at any position) of the existing table?
How can I do that in Postgres?
Any help would be appreciated.

hi
plz make use of Sql Help
hint: you can achieve this using ALTER TABLE Command
ALTER TABLE TABLENAME ADD COLUMNNAME DATATYPE(SIZE)

Thanks for the reply.
But it will add the new column at the last.
But i want it to get added at the middle.
Is there any way to achieve this.

Column ordering is not important within a SQL server database - why do you need to do this.

If it was me I would start by questioning the requirement, because it suggests that someone either doesn't know how databases work and/or are using it incorrectly for some other purpose.
But excluding that you would have to
1. Create temporary table.
2. Copy all of the data to the temp table.
3. Delete the original table.
4. Re-create with the new column
5. Copy all of the data back to the newly created table.
6. Delete the temp table.
Obviously you will need to deal with foreign keys appropriately. And it is likely that that the database can not be active (not processing work) while this is going on.

Hi
was wondering if anybody could help me. I was maid stored procedure as following:
USE [Spacva]
GO
/****** Object: StoredProcedure [dbo].[Test] Script Date: 11/13/2007 11:12:51 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[Test]
(
@START_DATE smalldatetime,
@END_DATE smalldatetime
)
AS
BEGIN
SELECT VOZILA.ID_VOZILA, VOZILA.PROIZVODNI_POGON, VOZILA.NAZIV, VOZILA.TIP, VOZILA.REG,
SUM(TOCENJE.KOL_L) AS Quantity, SUM(TOCENJE.SATI_RADA) AS Hours, SUM(TOCENJE.PROSJEK_L_PO_H) AS Average
FROM VOZILA INNER JOIN
TOCENJE ON VOZILA.ID_VOZILA = TOCENJE.ID_VOZILA
WHERE (TOCENJE.DATUM_UNOSA BETWEEN CONVERT(SMALLDATETIME, @START_DATE, 104) AND CONVERT(SMALLDATETIME, @END_DATE, 104))
GROUP BY VOZILA.ID_VOZILA, VOZILA.PROIZVODNI_POGON, VOZILA.NAZIV, VOZILA.TIP, VOZILA.REG
END
That stored procedure I was include in my Windows C# Project, just drag and drop to Win Form. My question is, how to add footer in established DataGrid, I mean how to add SUM of all selected values from column Quantity to my DataGrid?
I'm new in SQL, Visual .NET, C# so thanks in advance for help!

You either have two options. Either manually iterate through the items in the datagrid after it is populated, do the sum and add a row. Or you can do some 'ROLLUP' functionality in the SQL query so when you pull it down into the datagrid, it already has the sum values you want in their own row(s).
