No. That's the safe, short answer.

Are your customers actually writing SQL for executing against a database or is your app generating SQL? If instead the app's purpose is to provide a "power interface" to access data (read only?) and generate SQL, there are better choices. Use https query parameters to map to parameterized queries (https://blog.codinghorror.com/give-me-parameterized-sql-or-g...) which are a much better design choice.
