RE: SQL wildcard search

The underscore and percentage sign have special meaning within the LIKE
predicate. From the SQL Reference Guide:

* The underscore sign (_) represents any single character. 
* The percent sign (%) represents a string of zero or more characters. 
* Any other character represents itself. 

In order to use one of the special characters, you need to specify an
escape character. ie:

SELECT * FROM FILEA WHERE FLDA LIKE '%+_%' ESCAPE '+'

For more information, search for the LIKE predicate on the following
