Dynamic Execution of Stored Proc

  • Can someone please advise on the following:

    DECLARE @Database varchar(250)

    SET @Database = 'MBX_AE'

    use @Database;

    GO

    DECLARE @DependentObject varchar(250)

    SET @DependentObject = 'usp_stars_expand_sup_payout_matrix'

    DECLARE @Database varchar(250)

    SET @Database = 'MBX_AE'

    DECLARE @ThreePartIdentifier varchar(250)

    SET @ThreePartIdentifier = @Database + '.dbo.' + @DependentObject

    use @Database;

    GO

    SELECTb.xtype,

    b.name,

    a.definition

    FROMMBX_AE.sys.sql_modules a

    JOINMBX_AE.sys.sysobjects b

    ONa.[object_id]

    =b.id

    ANDb.name = @DependentObject

    exec sp_depends @ThreePartIdentifier

    Error Messages

    Msg 102, Level 15, State 1, Line 8

    Incorrect syntax near '@Database'.

    Msg 137, Level 15, State 2, Line 9

    Must declare the scalar variable "@DependentObject".

    Msg 137, Level 15, State 2, Line 12

    Must declare the scalar variable "@ThreePartIdentifier".

  • I think batch seperator is what is causing the problem and the USE statement, try this,

    DECLARE @ChangeDatabase nvarchar(250)

    Declare @database nvarchar(100)

    SET @database = 'SQLSERVERCENTRAL'

    SET @ChangeDatabase = 'USE ' + @database

    exec sp_executesql @ChangeDatabase;

    DECLARE @DependentObject nvarchar(250)

    SET @DependentObject = 'sp_addalias'

    DECLARE @ThreePartIdentifier nvarchar(250)

    SET @ThreePartIdentifier = @Database + '.sys.' + @DependentObject

    SELECTb.xtype,

    b.name,

    a.definition

    FROMSQLSERVERCENTRAL.sys.sql_modules a

    JOINSQLSERVERCENTRAL.sys.sysobjects b

    ONa.[object_id]

    =b.id

    ANDb.name = @DependentObject

    exec sp_depends @ThreePartIdentifier

  • what PP- said.. you can't USE a variable.. you have to build it into a string and execute the string..

    annoying from time to time.. but oh well 🙂

    I long for a job where my databases dont have any pesky users accessing them 🙂
