Hi,

In addition, filter formating differs throughout the program. The 
"Filtered features (SQL GDBMS)" option in the "Label class properties" 
throws up an error if you use quotation marks " rather than ' in the 
SQL. This does not appear to be a problem in 'Filter' commands used in 
the symbology tab --> Expressions --> [New filter] dialog or the Table 
Filter dialog used in the [Filter] button of the "toolbar" menu. The SQL 
used throughout the program should be standardized and error capturing 
routines established to avoid illegal characters being inserted into a 
SQL command. alternatively don't allow the user to enter commands 
directly but use a builder such as the one used in the Table filter.

Cheers Simon
