SQLError Mapping

  • Artikkeli

When an application calls SQLError through an ODBC 3.x driver, the call to

SQLError(henv, hdbc, hstmt, szSqlState, pfNativeError, szErrorMsg, cbErrorMsgMax, pcbErrorMsg)

is mapped to

SQLGetDiagRec(HandleType, Handle, RecNumber, szSqlstate, pfNativeErrorPtr, szErrorMsg, cbErrorMsgMax, pcbErrorMsg)

with the HandleType argument set to the value SQL_HANDLE_ENV, SQL_HANDLE_DBC, or SQL_HANDLE_STMT, as appropriate, and the Handle argument set to the value in henv, hdbc, or hstmt, as appropriate. The RecNumber argument is determined by the Driver Manager.
