Security

Avoiding SQL string concatenation: untrusted input concatenated with raw SQL query can result in SQL Injection. In order to execute raw query safely, prepared statement should be used. SQLAlchemy provides TextualSQL to easily used prepared statement with named parameters. For complex SQL composition, use SQL Expression Language or Schema Definition Language. In most cases, SQLAlchemy ORM will be a better option.

Distinct, Having, Group_by, Order_by, and Filter in SQLAlchemy can cause sql injections if the developer inputs raw SQL into the before-mentioned clauses. This pattern captures relevant cases in which the developer inputs raw SQL into the distinct, having, group_by, order_by or filter clauses and injects user-input into the raw SQL with any function besides “bindparams”. Use bindParams to securely bind user-input to SQL statements.
