Prototype

SQLRETURN SQLDisconnect(SQLHDBC    ConnectionHandle);

Parameters

Table 1 SQLDisconnect parameter

Keyword

Description

ConnectionHandle

Connection handle, obtained from SQLAllocHandle.

Return Values

  • SQL_SUCCESS indicates that the call succeeded.
  • SQL_SUCCESS_WITH_INFO indicates that some warning information is displayed.
  • SQL_ERROR indicates major errors, such as memory allocation and connection failures.
  • SQL_INVALID_HANDLE indicates that invalid handles were called. This value may also be returned by other APIs.

Precautions

If SQLDisconnect returns SQL_ERROR or SQL_SUCCESS_WITH_INFO, the application can call SQLGetDiagRec, with HandleType and Handle set to SQL_HANDLE_DBC and ConnectionHandle, respectively, to obtain the SQLSTATE value. The SQLSTATE value provides the detailed function calling information.
