If you are willing to impose a clause like that above, then just require
something similar in a comment preceding the statement in the mapper
file. Then your generic engine can look for such comments and apply the
constraints before invoking the query. Something like this:
<!-- @NotNull=col2Value, col3Value -->
<select id="sampleQuery" parameterType="Map" resultType="Map">
select column_1 from foo where column_2 = #{col2Value}
</select>
