Function Documentation

int kdbc_driver_available ( kdbc_driver driver )

Check if a driver's native library is available on this system.

Triggers a dlopen attempt on first call for the given driver. The result is cached — subsequent calls are cheap.

Parameters

driver The driver to check.

const char * kdbc_driver_name ( kdbc_driver driver )

Get the human-readable name of a driver.

Parameters

driver The driver to query.

kdbc_gk_strategy kdbc_driver_gk_strategy ( kdbc_driver driver )

Get the default generated-key strategy for a driver.

This is the compile-time default. For a connection-specific strategy (which may differ based on server version), use kdbc_conn_gk_strategy().

Parameters

driver The driver to query.

kdbc_gk_strategy kdbc_conn_gk_strategy ( kdbc_conn * conn )

Get the generated-key strategy for an open connection.

May differ from the driver default based on server version. For example, Oracle 12c+ returns KDBC_GK_BY_NAME while Oracle 11g returns KDBC_GK_NONE.

Parameters

conn	An open connection.

int kdbc_driver_supports_release_savepoint ( kdbc_driver driver )

Check if a driver supports RELEASE SAVEPOINT.

Oracle and MSSQL do not support releasing savepoints. Call this before using kdbc_release_savepoint().

Parameters

driver The driver to query.
