Updated: Feb 21, 2026

Technical Meaning

The error code ROWSNOTRELEASED (772, 0x304) indicates that the data provider requires previously fetched data to be released before additional data can be requested. This is a common scenario in database or data retrieval operations where resources are managed through explicit release mechanisms.

Error Details

This error typically arises when an application attempts to fetch more rows from a data source without properly releasing the resources associated with previously retrieved rows. The data provider expects that once data has been fetched, the application must explicitly release those resources before making further requests for additional data.

Usage Context

This error is commonly encountered in scenarios involving database operations or any API that manages data retrieval through explicit resource management mechanisms. It can occur when an application fails to follow proper protocol for releasing data resources, leading to a state where more data cannot be fetched until the previous data has been properly released.

Developer Interpretation

Developers should ensure that their applications correctly manage and release resources associated with previously retrieved data before making further requests. This is crucial for maintaining efficient and stable operation of data retrieval processes, especially in scenarios involving large datasets or high-frequency data access.
