SQL Server Error Mapping

This page lists how native SQL Server database or driver errors are represented as TsSqlErrorReason values. The table uses the same row catalog and row order as the other native database pages, so a - means this semantic case is not currently mapped for SQL Server.

Database error shows the values exposed through databaseErrorCode and databaseErrorNumber when both are available. Connector-only signals include the connector inline. SQL_UNKNOWN is intentionally the last row.

SQL Server engine errors are number-first. Microsoft documents Database Engine failures by error number or message_id, with related attributes such as severity, state, procedure, line, and message text. When those engine errors come through mssql, they are commonly exposed as a RequestError with code equal to EREQUEST; the same error object carries the native SQL Server number in number. For rows such as EREQUEST / 2627, EREQUEST tells you the error came through the driver request wrapper, and 2627 is the SQL Server-specific discriminator used by the mapper. Driver-only signals such as ETIMEOUT, ELOGIN, or EARGS are listed by their textual code because they are not SQL Server engine numbers.

Exact mapper-known codes are listed individually. Broad class, range, or message-pattern fallbacks are kept when the mapper intentionally handles an open-ended family of errors; if the same native code appears in more than one row, the driver message determines the final mapped reason.
