SQLGetDiagField

  • Artikel

The SQL Native Client ODBC driver specifies the following additional diagnostics fields for SQLGetDiagField. These fields support rich error reporting for SQL Server applications and are available in all diagnostics records generated on connected ODBC connection handles and ODBC statement handles. The fields are defined in sqlncli.h.

Diagnostics record field Description

SQL_DIAG_SS_LINE

Reports the line number of a stored procedure generating an error. The value of SQL_DIAG_SS_LINE is meaningful only if SQL_DIAG_SS_PROCNAME returns a value. The value is returned as an unsigned, 16-bit integer.

SQL_DIAG_SS_MSGSTATE

The state of an error message. For information about the error message state, see RAISERROR. The value is returned as a signed, 32-bit integer.

SQL_DIAG_SS_PROCNAME

Name of the stored procedure generating an error, if appropriate. The value is returned as a character string. The length of the string (in characters) depends on the version of the SQL Server. It can be determined by calling SQLGetInfo requesting the value for SQL_MAX_PROCEDURE_NAME_LEN.

SQL_DIAG_SS_SEVERITY

The severity level of the associated error message. The value is returned as a signed, 32-bit integer.

SQL_DIAG_SS_SRVNAME

The name of the server on which the error occurred. The value is returned as a character string. The length of the string (in characters) is defined by the SQL_MAX_SQLSERVERNAME macro in sqlncli.h.

SQL Server-specific diagnostic fields that contain character data, SQL_DIAG_SS_PROCNAME and SQL_DIAG_SS_SRVNAME, return that data to the client as null terminated, ANSI, or Unicode strings. If necessary, the count of characters should be adjusted by the character width. Alternately, a portable C data type such as TCHAR or SQLTCHAR can be used to ensure correct program variable length.

The SQL Native Client ODBC driver reports the following additional dynamic function codes that identify the last attempted SQL Server statement. The dynamic function code is returned in the header (record 0) of the diagnostics record set and is therefore available on every execution (successful or not).
