Re: using text search

Hi Rafal

This function returns the position where the substring is found, so you could do a query with clause
position(table1.fieldin table2.field) 

The 0 result is not found and maybe, in your case, is faster the use of internal text functions instead of like
comparison...hope helps. 

Bye
