#includeIn this code example, after setting up the ODBC connection, a SQLTransaction object is created, and the transaction is initiated using the Begin method. Multiple SQL queries are executed, and the transaction is committed using the Commit method. Package/Library: SQLTransaction is not a standard part of the C++ language; rather, it is implemented as a part of a specific package or library. The package/library that contains the SQLTransaction class depends on the database management system (DBMS) being used. For example, you might find SQLTransaction in libraries like ODBC, ADO.NET, or JDBC, depending on the language and database you're using.#include #include #include int main() { SQLHENV henv; SQLHDBC hdbc; SQLRETURN ret; SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &henv); SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION, (SQLPOINTER) SQL_OV_ODBC3, SQL_IS_INTEGER); SQLAllocHandle(SQL_HANDLE_DBC, henv, &hdbc); SQLAllocHandle(SQL_HANDLE_STMT, hdbc, &hstmt); ret = SQLConnect(hdbc, (SQLCHAR*) "dsn", SQL_NTS, (SQLCHAR*) "user", SQL_NTS, (SQLCHAR*) "password", SQL_NTS); SQLTransaction htrans; htrans.Begin(); SQLExecDirect(hstmt, (SQLCHAR*) "INSERT INTO customer VALUES (1, 'John Doe', '[email protected]')", SQL_NTS); SQLExecDirect(hstmt, (SQLCHAR*) "INSERT INTO customer VALUES (2, 'Jane Doe', '[email protected]')", SQL_NTS); htrans.Commit(); SQLFreeHandle(SQL_HANDLE_STMT, hstmt); SQLDisconnect(hdbc); SQLFreeHandle(SQL_HANDLE_DBC, hdbc); SQLFreeHandle(SQL_HANDLE_ENV, henv); return 0; }
