"Is Equal To" operator is not working with custom text fields

The SQL statement generated for the "=" operator uses the "%" wildcards commonly used with the "LIKE" operator. While this works well with "LIKE", it breaks the "=" functionality.

Today, the statement generated is something like this:

UPPER( <table>.<field> ) = UPPER( '%<value>%' )

While the correct form is:

UPPER( <table>.<field> ) = UPPER( '<value>' )

The proposed patch fix this issue.
