SQL Stored Procedure to Delete Zero Value Sift Fields

edited 2007-03-20 in NAV Tips & Tricks
The following SQL SP will delete the rows in SIFT tables which have zero values. It builds the SQL Statements dynamically, so if a table is modified it will automtically pick these changes up.

Then re-indexing can be scheduled in SQL alos & the NavisionOptimisation tasks are not required.

    I ran it and it worked. one issue. If company name has space inbetween, you can't run the above statement.

    Thanks again for sharing this.
