Purpose

Determines how the driver returns column metadata when retrieving results with ResultSetMetaData methods.

Valid Values

true | false

Behavior

If set to true, the driver makes an additional roundtrip to the database to retrieve actual values for column metadata. For example, the driver returns nullability as IS_NULLABLE, NOT_NULLABLE, or NULLABILITY_UNKNOWN, depending on the actual status of the column.

If set to false, the driver returns only the values for column metadata hardcoded in the driver. For example, the driver returns nullability as NULLABILITY_UNKNOWN.

Notes

Setting ExtendedColumnMetadata to enabled may diminish performance because an additional roundtrip to the database is required to retrieve actual values for the column metadata.
