SQLSetDriverConnectInfo Function

  • Artikkeli

Conformance
Version Introduced: ODBC 3.81 Standards Compliance: ODBC

Summary
SQLSetDriverConnectInfo is used to set the connection string into the connection info token for an application's SQLDriverConnect call.

Syntax

  
SQLRETURN SQLSetDriverConnectInfo(  
                SQLHDBC_INFO_TOKEN   hDbcInfoToken,  
                WCHAR *              InConnectionString,  
                SQLSMALLINT          StringLength1 );

Arguments

TokenHandle
[Input] Token handle.

InConnectionString
[Input] A full connection string (see the syntax in "Comments" in SQLDriverConnect), a partial connection string, or an empty string.

StringLength1
[Input] Length of *InConnectionString, in characters if the string is Unicode, or bytes if string is ANSI or DBCS.

Returns

SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_ERROR, or SQL_INVALID_HANDLE.

Diagnostics

Same as SQLDriverConnect related to any input validation error, except that the Driver Manager will use a HandleType of SQL_HANDLE_DBC_INFO_TOKEN and a Handle of hDbcInfoToken.

Remarks

Whenever a driver returns SQL_ERROR or SQL_INVALID_HANDLE, the Driver Manager returns the error to the application (in SQLConnect or SQLDriverConnect).

Whenever a driver returns SQL_SUCCESS_WITH_INFO, the Driver Manager will obtain the diagnostic information from hDbcInfoToken, and return SQL_SUCCESS_WITH_INFO to the application in SQLConnect and SQLDriverConnect.

Applications should not call this function directly. An ODBC driver that supports driver-aware connection pooling must implement this function.

Include sqlspi.h for ODBC driver development.
