如何正确地将导入的 SQL 查询转换为 SSRS 中的表达式字符串

Question

很抱歉打扰大家，这应该是一个微不足道的问题，但我需要将一个 SQL 查询导入到 SSRS 的报表生成器中，然后将其转换为一个表达式（以便我可以使用它的连接运算符将参数的值连接到搜索字符串中）。

作为第一阶段，我将我的查询（我知道它有效）复制并粘贴到 SSRS 中，运行顺利进行。但是，一旦我将表达式放在引号中，并在整个表达式前加上“=”前缀，我就会收到一些非常无用的语法错误消息。

这是我在导入 SSRS 之前的（正常运行的）查询：

DECLARE @From Date='1/1/2015'
DECLARE @To Date='1/3/2020'
DECLARE @Doctors varchar(5)='ABC'
DECLARE @Intents varchar(20)='RoutineRad-Cat2'
DECLARE @DiagnosisTypes varchar(20)='ICD-10'

SET transaction isolation level read uncommitted;

    x.Expression1 as 'Intent',
    x.IntentCategory,
    x.StartDateTime as 'Ready To Start Treatment Date',
    x.LastName as 'Surname',
    x.PatientId as 'Patient ID',
    x.DoctorId as 'Primary Oncologist',
    x.TreatmentStartTime as 'First RT Treatment Date',
    datediff(dd, x.StartDateTime, x.TreatmentStartTime) as 'Wait in days',
    x.TargetMet,
    x.Delayed,
    x.TxStartSortDate

...但我只收到错误消息“关键字 'VALUES' 附近的语法不正确。 ')' 附近的语法不正确。"

我不知道如何着手解决这个问题，因为我知道我的 SQL 很好。我已尝试将查询导入 Scite 并查看行结尾/特殊字符，但这看起来也不错。

有人可以帮我吗？

祝福

Answer 1

看来您需要将每一行都用引号引起来，并且 link 和 & 引起来才能完成这项工作。我一直无法弄清楚为什么。我还使用换行符将结果查询中的行分开。

="SET transaction isolation level read uncommitted; " & VBCRLF 
" " & VBCRLF 
"SELECT " & VBCRLF 
"    x.Expression1 as 'Intent', " & VBCRLF 
"    x.IntentCategory, " & VBCRLF 
…

在 Notepad++ 中，您可以找到 \r\n 并替换为 " & VBCRLF & \n" 以自动添加它们 - 尽管您需要执行第一个和最后一个。
