使用OCCI oracle在C ++中執行PL / SQL腳本

Question

我想從C ++程序運行SQL腳本。 我的代碼是這樣的：

int main()
{ 
//.....
sql_stmt = "Insert into t1 values ('qwerty');\nInsert into t1 values ('dothar');"
           "//and many more INSERT statements";

sql_stmt = "DECLARE\nrollback_check_counter number;\n"
"BEGIN\n"
"rollback_check_counter :=1;\n"
"SAVEPOINT sp_1;\nIF rollback_check_counter = 1 THEN\n"
"BEGIN\n"+sql_stmt+"EXCEPTION\n"
"WHEN PROGRAM_ERROR THEN\n"
"rollback_check_counter :=0;\n"
"ROLLBACK TO sp_1;\n"
"WHEN OTHERS THEN\n"
"rollback_check_counter :=0;\n"
"ROLLBACK TO sp_1;\n"
"END;\n"
"END IF;\n"
"commit;\n"
"END;";


try 
{
    Connection *conn = env->createConnection(user,passwd); //error prone
    Statement *stmt = conn->createStatement();
    stmt->setSQL(sql_stmt);
    row_count = stmt->execute(); //stmt->execute(sql_stmt);

    Connection::conn->terminateStatement(Statement *stmt);
    //con->terminateStatement(stmt);
    env->terminateConnection(conn);
    Environment::terminateEnvironment(env);
}
catch(SQLException& ex)
{}
//.....
return 0;
}

雖然當我運行這些insert語句時它們只能運行良好，但是當我形成SQL Script結構時它們似乎會失敗。 我想這樣做是因為我想實現回滾。 我想念什么？ 任何人都可以提出任何替代方案來實現它。

有; 兩次ROLLBACK TO sp_1后都丟失
