INSERT INTO与DB

Question

可变我想插入：

• 数据库TEST，表SUBJECT，现场aSubject当@Database = 'TS'
• 数据库TEST1，表SUBJECT，现场aSubject当@Database = 'TS1'
• 别的数据库DEMO，表SUBJECT，字段aSubject

我尝试这样做：

DECLARE @Database varchar(10) 
Set @Database = 'TS' 

INSERT INTO 
(
CASE 
WHEN @Database = 'TS' THEN 'TEST.dbo.SUBJECT' 
WHEN @Database = 'TS1' then 'TEST1.dbo.SUBJECT' 
ELSE 'DEMO.dbo.SUBJECT' END 
) (aSubject) 
SELECT 'Company' 

我得到错误：

Msg 102, Level 15, State 1, Line 5 
Incorrect syntax near '('. 

Answer 1

DECLARE @Database SYSNAME; 
Set @Database = 'TS' 

SET @Database = CASE 
        WHEN @Database = 'TS' THEN 'TEST' 
        WHEN @Database = 'TS1' THEN 'TEST1' 
        ELSE 'DEMO' 
       END 


DECLARE @sql NVARCHAR(MAX); 


SET @sql= N' INSERT INTO ' + QUOTENAME(@Database) + N'.[dbo].[SUBJECT] ' 
     + N' SELECT ''Company'' ' 

EXECUTE sp_executesql @sql
