Using Parameter In SP As Tablename
Jul 20, 2000
Does anyone know the syntax to reference a table in a stored procedure using a parameter? I'm trying to make a stored procedure that will "SELECT INTO" a table as the passed parameter. I keep getting an syntax error when I use this:
CREATE PROCEDURE make_table
@tablename varchar(20)
AS
SELECT * FROM old_table
INTO @tablename
I've tried it several ways, but I can't get it to work, and I haven't found any examples of this anywhere. Thanks in advance for any tips.

HiCan someone please shed some light as to how this can be done. With the below sql statement as you can see I don't want to declare the table name but would rather the table name be passed in via a parameter. I've tried declaring it as a varchar parameter but it doesnt seem to like it if I don't add a valid table name. Any ideas how this can be done. Thanks.select * from @tableName where condition = condition

Hi all.
I want something like this :
create proc myProc ( @num int ,@name varchar(80))
as
select @num = max(field1) from @name
but there is a problem that the @name is a varchar and the error is :
Server: Msg 170, Level 15, State 1, Procedure sp_myProc, Line 3
Line 3: Incorrect syntax near '@name'.
I tried
select @num = max(field1) from object_id(@name)
and the error was the same
is ther another way than :
exec ("declare @num int select @num = max(field1) insert into anotherTable values( @num) " ) ?
thx

Hi,
What is the difference between
<Tablename> . . <ColumnName> and <Tablename> . <ColumnName>
this syntax we are using in Storedprocedures.
In SQL 2000, <Tablename> . . <ColumnName> is not working
Eg:
Tablename =a
Column Name = b
Difference between a..b and a.b
Can anyone let me know.
TIA,
Ravi

I know there has already been a thread on this, but I want to push some about it.
In SQL Server, there is a command "SET IDENTITY_INSERT tablename ON".
That allows you to update IDENTITY columns, or do INSERTs that include IDENTITY columns. Although a work-around was given for this in the other thread (reset the IDENTITY seed to the desired value before each INSERT), that is a major pain.
In my database, I have a table that tracks charitable donors. They have a donornum, that is an IDENTITY column, and a year. Together, the donornum and the year form the primary key. Each year end, a copy is made of all donor records in one year, to form the next year's donors. They have to keep the same donornum, but they get a new year value of course. Adding new donors uses the donornum normally, incrementing the IDENTITY donornum value.
The advantage of this is that you can match up one year's donors with the previous year's, by joining on donornum. But I need there to be separate records, so they can have separately updated addresses, annual pledge amounts, etc.
Is there any way the SET IDENTITY_INSERT feature can be added to SQL Everywhere, or some other approach can be found that is less laborious than the existing work-around? (The problem with it is that if you have hundreds of donors to copy, you have to do one ALTER TABLE to reset the identity seed for each donor insert for the new year.)
Thanks.

I use IDENTITY(1,1)
and the help says:
SET IDENTITY_INSERT tablename ON
But if the table is an variable(virtual) table how to make it work?
Like this:
DECLARE @TEMPtable table ( ID int Identity(1,1), invar nvarchar(255)
It does not work with
SET IDENTITY_INSERT @TEMPtable ON
I get this
'Incorrect syntax near '@TEMPtable '

this error returned because max(id_no) column is absent
if you are run
select * from
(select max(name) insqlhelp 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

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

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!

Hi,
I am new to SQL Server, and this may be a silly problem .. but here goes!
I need to create tables based on the date ie FEB2000 for EOM reports, I thought I may be able to do it by
1) Check if Table Exists, if so fop it
2) Recreate Table
3) Populate it with data
Unfortunately I'm still on step 1 <sad look>
--->
CREATE PROCEDURE TEST AS
DECLARE @TableName varchar(50)
SET @Tablename = 'FEB2000'
IF EXISTS(SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME = @Tablename)
DROP TABLE @tablename
GO
<---
I would of course hand the table name as a variable, but for testing purposes used a set variable.
Thanks in Advance

I have read through BOL but am still confused by the above sql. I think it rebuilds all indexes on a table. Am I correct? (If so, if would seem to be a good thing to run it nightly on all tables in all databases. Or maybe that is too extreme)

I am doing a mass update of our SQL script files by adding dbo.to all references to the tables.The code is also adding dbo. in front of existing lines of codethat are like this:SELECT CLIENT.FIRSTNAME,CLIENT.LASTNAMEFROM CLIENT....The mass update is causing this to become:SELECT dbo.CLIENT.FIRSTNAME,dbo.CLIENT.LASTNAMEFROM dbo.CLIENT....My goal is to see FROM dbo.CLIENTbut even the column names are getting the "dbo."added, so my question is if there's any performanceloss or any other side effect if I end up all my columnswith a preceeding "dbo."?Thank you

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.

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.
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)
