Used to enable dynamic data reading and reduce memory consumption during data retrieval.

Unit

Syntax

Remarks

Allows reading data of the VARCHAR2, NVARCHAR2, and RAW types. If a column size is greater than or equal to the value specified in this option, data will be fetched using the OCI_DYNAMIC_FETCH mode. While this mode can significantly reduce memory consumption during data retrieval, it may also negatively impact performance.

The default value is 0, which disables reading data in the OCI_DYNAMIC_FETCH mode.
