Security
Security Notice This class generates SQL queries for the given database. The SQLDatabase class provides a getTableInfo method that can be used to get column information as well as sample data from the table. To mitigate risk of leaking sensitive data, limit permissions to read and scope to the tables that are needed. Optionally, use the includesTables or ignoreTables class parameters to limit which tables can/cannot be accessed.
