Prepared Statement functions - Efficiently execute statements multiple times and has support for failover
Database Bulk functions - Bundle multiple queries into one SQL statement
All database-related APL functions use a db connection pool, and they pick a connection from the pool for each invocation. Connection properties, such as the transaction state, are handled internally by each function and are never visible in APL.
These database functions are currently designed to work with the following database data types;character,string,integeranddatedata types such as VARCHAR, INTEGER, NUMBER, DATE and TIMESTAMP.
Other database data types are restricted for APL database functions. The list below contains examples of such types, usually very large data types or custom objects, structures and similar types.
Large object data types such as BLOB/CLOB
PostgreSQL does not support BLOB/CLOB. The BLOB equivalent for PostgreSQL will be BYTEA and CLOB equivalent will be TEXT.
