Question

我们需要创建一个tinymce.get("textfull").getBody().innerHTML = d.Description; script，insert仅新created offices和districts Data table。我们需要检查新Office District和tables Records，如果数据存在，我们需要insert。

我们已经尝试了以下语法，

IF EXISTS (
    SELECT 1
    FROM [dbo].[office] o
    LEFT OUTER JOIN [dbo].[Datatable] a ON (o.OfficeID = a.OfficeID)
    WHERE a.OfficeID IS NULL
)
OR (
IF EXISTS (
    SELECT 1
    FROM [dbo].[District] o
    LEFT OUTER JOIN [dbo].[Datatable] a ON (o.DistrictID = DistrictID)
    WHERE a.DistrictID IS NULL
)
)
BEGIN
   -- //CODE
END

但SSMS为此提供了syntax error。如何实现上述场景？

应该是... OR EXISTS(而不是OR ( if EXISTS(：

IF EXISTS
 (
     SELECT 1
     FROM [dbo].[office] o
     LEFT OUTER JOIN [dbo].[Datatable] a
        ON (o.OfficeID = a.OfficeID )
     WHERE  a.OfficeID IS NULL
 )
OR EXISTS
 (
     SELECT 1
     FROM [dbo].[District] o
     LEFT OUTER JOIN [dbo].[Datatable] a
        ON (o.DistrictID = DistrictID )
     WHERE  a.DistrictID IS NULL
 ) 
BEGIN
    //CODE
END

如何在sql server中使用带有OR子句的IF EXISTS语句
