My first step is to select out the sql need to be execute from table SQL_Stored. I tried to get the SQL by using a simple select statement such as:

Select Download_Sql As Query From SQL_Stored
Where ID=@ID AND TableName=@TableName

Try this:

DECLARE @download_sql VARCHAR(MAX)
Select
    @download_sql = Download_Sql
From
    SQL_Stored
Where
    AreaID = @AreaID
    AND TableName = @TableName

EXEC (@download_sql)
