Create parameter for a table in a procedure

  • This seems really easy but I can't find any references to what I'm doing wrong.

    Here is my code:

    CREATE PROCEDURE dbo.QryAllTable (@TableName varchar(50))

    AS

    BEGIN

    SELECT *

    FROM @TableName

    END

    GO

    The procedure won't create because it says I have invalid syntax on the From line. Can I not pass a string a string parameter to the From clause?

    Thanks for the help.

  • It ill not work.

    You are selecting from a STRING not from a table.

    If are you trying do create a generic "select * from" using a parameter to pass the name of the table you can achieve it using dynamic SQL.

    Read about it in BOL and try again.

  • You will have to have a local string variable and pass the parameter value to that local variable and execute that..

    in short, this is how it should look like..

    DECLARE @sql VARCHAR(1000)

    SET @sql = 'SELECT * FROM ' + @TABLENAME

    EXEC (@SQL)
