Note!

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, integer and date data types such as VARCHAR, INTEGER, NUMBER, DATE, TIMESTAMP and TIMESTAMPBOOLEAN.  

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

• User-defined structures/objects

• User-defined collections/arrays

• Spatial/Geometry

• JSON, XML
