  Is there a way to use a variable for the table name in a from statement?  I'm using a cursor to loop through and run the same query on a bunch of tables but whenever I try to use a var for the table name it tells me I need to declare the variable

  Test Example:

  Declare   @Tbl_Name varchar(20)

  Set @Tbl_Name = 'My_Table'

  Select * From @Tbl Name (This gives me an error that I need to declare the variable @Tbl_Name)

  Yet Print @Tbl_Name is OK...

  TIA, Erin

  I know that using exec, you can have a variable name in the from clause.

  exec('Select * From '+ @Tbl Name)

  Hoping this helps...

  You can use dynamic sql:

   

  Declare   @Tbl_Name varchar(200)

  Declare   @sql varchar(200)

  Set @Tbl_Name = 'YourTable'

  set @sql = 'Select * From '+@Tbl_Name

  exec(@SQL)
