在SSIS C＃脚本中的位置[关闭]

Question

我在SSIS脚本中有下面的查询。

string query = "Select distinct " + ColumnNameForGrouping + " from " + TableName + "where flag like '%investigation%'" ;

它给出了以下错误消息。

System.Data.SqlClient.SqlException (0x80131904): Incorrect syntax near the keyword 'like'.
   at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction)

我猜它不喜欢单引号或百分号。你如何使用C＃在SSIS脚本中编写WHERE - LIKE？

有关信息，在我只使用下面的查询而没有Where - LIKE子句之前，它工作正常。

string query = "Select distinct " + ColumnNameForGrouping + " from " + TableName

我正在使用Microsoft Server 2012。

谢谢大家的帮助。

韩的答案：

在那里放一个空格。它应该是+“其中标志像'％investigation％'”;如果名称包含空格或保留字，您也可以尝试在列名和表名之前添加括号。 - 汉族43分钟前
