  Create function [GetTableData] (@TableName varchar(50),@RowID integer)

  Declare @MySQL varchar(100);

  Set @Mysql= 'select * from ' + @TableName + ' where id = ' + @RowID

  The RETURNS clause is missing the definition of the output table. See here.

  Also, EXEC can only be used within a function to call an extended stored procedure.
