子查詢返回不止一個值，不允許變量是=，=，<, <= , >，> =

四處錯誤：子查詢返回不止一個值，不允許變量是=，=，<, <= , >，> =

Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

請幫我這個查詢：

DECLARE @TYPENAME varchar(20) = 'Hardness'; 
DECLARE @MODEL varchar(20) = 'LEEB'; 
DECLARE @SPECIFICATION varchar(20) = 'Other'; 
DECLARE @EQUIPMENT varchar(20) = 'Phase II Model: PHT-18 00 S/N: PHO109112815';

該問題可能是在'CASE'表達式，其中子查詢返回不止一個值。你需要修正那裏的邏輯。 –

我不認爲@TimBiegeleisen是對的。內部選擇預計會返回一個或多個值（請參閱條件'... AND Document.Guid in ...'）。我建議你重新安排你的內部查詢到一個更可讀的佈局和檢查括號。 – FDavidov

設置[壞習慣踢 - 把NOLOCK無處不在]（http://blogs.sqlsentry.com/aaronbertrand/bad-habits-nolock-everywhere/） - 它是*不推薦*到處使用 - 完全相反！ –

您的查詢做工精細@Zohar佩萊德但性能變差，所以我自己找到了解決方案，通過分離條件整個查詢發現下面，

我很確定@TimBiegeleisen是正確的，但沒有解釋好。我認爲這裏的問題是使用case。取而代之的case，我會簡單地使用or：

（注：你可能會得到一個語法錯誤由於錯位的parenthasis，那裏有那麼多的人我有點迷路了）
