Changing the statement or the expression or VBScript expression (Aviation)

The Structured Query Language (SQL) statement must be modified to change the symbols selected for a rule, or the Visual Basic Scripting Edition (VBScript) expression must be changed to accommodate new conditions within the SQL statement.
