MAJORDatabase query built from text
Database query built from text
A SQL statement is assembled by inserting values into the query text. If any of those values comes from a user or from model output, as in text-to-SQL agents, it can rewrite the query.
Pass values as bound parameters and allow-list identifiers such as table and column names.
