Question

我正在运行连接到Oracle DB和ADODB的Excel VBA代码。我可以使用以下连接字符串连接到Oracle服务器： dbConnectStr = "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST='Host')(PORT='Port'))(CONNECT_DATA=(SERVICE_NAME='service')));Data Source='Source'; User Id='User';Password='Password"

With dbConnection
    .ConnectionString = dbConnectStr
    .Properties("Prompt") = adPromptNever
    .Open ConnectionString
End With

我可以执行选择命令。

但是当我尝试执行以下SQL Update命令后面跟着＆＃34; COMMIT＆＃34;时，我收到Oracle错误：ORA-0091：无效字符。

在省略Commit时，错误消失。

   sSQL = "UPDATE EMPLOYEE SET DOJ ='31-DEC-9999' WHERE EMP_ID =55555; COMMIT;"

    With dbCommand
        .ActiveConnection = dbConnection
        .CommandText = sSQL
        .CommandType = adCmdUnknown
        .CommandTimeout = 600
    End With

    Set dbRecordset = dbCommand.Execute

有＆＃34; COMMIT＆＃34;在SQL中是我不可或缺的要求，我不能忽视或替换其他东西。

请帮忙。提前致谢 Sachin D

Answer 1

您的更新和提交是2个命令。您不能在同一个execute中执行这两个命令。你需要做2次执行。通常，您应该使用Split(sSQL, ";")之类的内容拆分脚本。这将为您提供一个字符串数组，可以使用for循环轻松遍历。

您还必须处于事务模式，以便在命令execute中接受提交。您可以使用dbConnection.BeginTrans和dbConnection.CommitTrans围绕您的循环来完成此操作。

如果您不处于事务模式，则每个执行都将立即提交。

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    AFHTTPRequestSerializer * requestSerializer = [AFHTTPRequestSerializer serializer];
    AFHTTPResponseSerializer *responseSerializer = [AFHTTPResponseSerializer serializer];

    [requestSerializer setValue:ua forHTTPHeaderField:@"User-Agent"];
    responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/xml", nil];
    manager.responseSerializer = responseSerializer;
    manager.requestSerializer = requestSerializer;

              loginViewController = [[LoginViewController alloc] init];
              [self presentViewController:loginViewController animated:YES completion:nil];

          }
          failure:^(AFHTTPRequestOperation *operation, NSError *error) {
              NSLog(@"Error: %@", error);
          }];

无法在ADODB.COMMAND中执行“提交”
