SQLTransact Mapping

  • Článok

SQLTransact is now replaced by SQLEndTran. The major difference between the two functions is that SQLEndTran contains an argument HandleType, which specifies the scope of the work to be done. The HandleType argument can specify the environment or the connection handle. The following call to SQLTransact:

SQLTransact(henv, hdbc, fType)

is mapped to

SQLEndTran(SQL_HANDLE_DBC, ConnectionHandle, CompletionType);

if ConnectionHandle is not equal to SQL_NULL_HDBC. The ConnectionHandle argument is set to the value of hdbc.

SQL_Transact is mapped to

SQLEndTran (SQL_HANDLE_ENV, EnvironmentHandle, CompletionType);

if ConnectionHandle is equal to SQL_NULL_HDBC. The EnvironmentHandle argument is set to the value of henv.

In both of the preceding cases, the CompletionType argument is set to the same value as fType.
