Removes query selection criteria from the QueryString property that were added by assignQuerySelection.

Location: query.p

Parameters:

INPUT pcColumns AS CHARACTER

A comma separated list of column names that are the subject part of a phrase to be removed.

INPUT pcOperators AS CHARACTER

The operator (one for all columns):

A blank defaults to (EQ).
A slash is used to define an alternative string operator (EQ/BEGINS, and so forth).
A comma separated list for each column/value.

Notes: This procedure modifies the QueryString property and is designed to run on the client and called several times before QueryString is used in a QUERY–PREPARE method to modify the database query. openQuery prepares the query using the QueryString property. The removal of the expression is done by finding the value of which position and length is stored in the QueryColumns property.
