OleDbError

OleDbError is a class in the System.Data.OleDb namespace of the .NET Framework. It represents a single error that occurred during an OleDb operation. When an OleDb operation fails, it can return a collection of OleDbError objects, accessible through the OleDbErrorCollection property of an OleDbException.

Each OleDbError object contains details about the specific error, including an error code, a description of the error, and the source of the error. The ErrorCode property provides a unique numerical identifier for the error, which can be useful for programmatic handling and logging. The Message property offers a human-readable explanation of what went wrong. The Source property indicates the component or module that generated the error, often identifying the OleDb provider.

Developers typically encounter OleDbError objects when interacting with databases using OleDb providers, such as when executing SQL queries or performing data modifications. By examining the properties of OleDbError objects within an OleDbException, developers can diagnose and resolve issues related to database connectivity, invalid SQL syntax, or data integrity problems. Handling these errors gracefully is crucial for building robust and reliable applications that interact with data sources.
