>I have an SQL statement that LEFT joins two tables. When the table are joined a .null. is placed in fields where there was no data in the second table. One of those fields is a memo field. What I am trying to do is prevent the .null. from being placed in the memo field. Here is the code I am trying. The field extratext is the memo field.
