我正在尝试向 SSIS 中的条件拆分转换添加条件，但条件中字符串开头的双引号字符会引发错误。
这是我的条件：
(FirstName != LkUp_FirstName) || ((ISNULL(MiddleName) ? “abc” : MiddleName) != (ISNULL(LkUp_MiddleName) ? “abc” : LkUp_MiddleName)) || (LastName != LkUp_LastName)
这是我在条件拆分转换编辑器上单击确定时收到的错误消息的开头：
Error at Data Flow Task [Conditional Split [105]]: Attempt to parse the expression "(FirstName != LkUp_FirstName) || ((ISNULL(MiddleName) ? “abc” : MiddleName) != (ISNULL(LkUp_MiddleName) ? “abc” : LkUp_MiddleName)) || (LastName != LkUp_LastName)" failed. The token " " at line number "1", character number "57" was not recognized. The expression cannot be parsed because it contains invalid elements at the location specified.
我试图通过将条件更改为：
(FirstName != LkUp_FirstName) || ((ISNULL(MiddleName) ? \“abc\” : MiddleName) != (ISNULL(LkUp_MiddleName) ? \“abc\” : LkUp_MiddleName)) || (LastName != LkUp_LastName)
但后来我收到以下错误：
数据流任务 [条件拆分 [105]] 出错：尝试解析表达式“(FirstName != LkUp_FirstName) || ((ISNULL(MiddleName) ? \“abc\” : MiddleName) != (ISNULL(LkUp_MiddleName) ? \“abc\” : LkUp_MiddleName)) || (LastName != LkUp_LastName)" 失败。无法识别行号“1”、字符号“57”处的标记“\”。无法解析表达式，因为它在指定位置包含无效元素。
