- colejohnson66 4y agoI think GP is saying they view SELECT as a "pure" function. A pure function doesn't modify state, so neither should SELECT.
- bombcar 4y agoYeah, from limited experience with SQL "SELECT is safe" (assuming no weirdness in sub functions or commands) but that's clearly not always the case.
