僅供參考,如果您想閱讀: (我正在研究SQL數據庫更新程序,我有一個(舊)ICD代碼表,並且我想插入新記錄(約90k記錄),如果沒有已存在的ICD代碼,則插入,如果是,則更新。問題是要插入的數據來自表格調用IcdImportData(從.csv文件導入),我需要創建變量表包含舊錶和新IMPORTDATA表的比較值)SQL從SELECT結果插入表變量
我想諮詢一下: 我想插入值變量表,SELECT語句日在返回許多記錄。我怎樣才能做到這一點?
這是代碼:
SELECT IcdCodeID FROM
(
SELECT IcdCodeID FROM IcdImportData
UNION ALL
SELECT IcdCodeValue FROM IcdCode
) tmp
GROUP BY IcdCodeID
HAVING COUNT(*)>=2
,我想結果插入到這個變量表:
DECLARE @temp table (IcdCodeValue NCHAR(10))
INSERT INTO @temp
SELECT
(
*The code above*
)
的錯誤:
Msg 512, Level 16, State 1, Line 2 Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression. The statement has been terminated.
見'INSERT'語法爲您的RDBMS – Alexander
請表明發生故障的實際INSERT語句。另外,這是什麼數據庫? – 2014-03-27 07:31:38
