Parameterized queries can be reused and mitigate SQL injection attacks. You can execute SELECT and other SQL data manipulation statements as parameterized queries. Parameterized queries take arrays as input.

Example: Searching Epicor Kinetic

The following example macro executes a parameterized search: When you run the macro, you are prompted to enter a search value.
