附近有語法錯誤「取代」

Question

下面的SQL語句顯示與打印，但與EXEC堅實的成果，給了我附近有語法錯誤「取代」

USE EPDB 

DECLARE @Table as nvarchar(100) 
DECLARE @Column as nvarchar(100) 
DECLARE @Select as nvarchar(375) 
DECLARE @Where as nvarchar(275) 

SET @Table = 'TableABC' 
SET @Column = 'ColumnABC'`enter code here` 
SET @Select = 'SELECT * FROM INFORMATION_SCHEMA.COLUMNS' 
SET @Where = 'CRITERIA = ''VALUE''' 


-- EXEC ('SELECT * FROM INFORMATION_SCHEMA.COLUMNSWHERETABLE_NAME = ' + @Table + '''') 

PRINT @Select + ' WHERE ' + REPLACE(REPLACE(@Where,'CRITERIA','TABLE_NAME'),'VALUE',@Table) 

EXEC (@Select + ' WHERE ' + REPLACE(REPLACE(@Where,'CRITERIA','TABLE_NAME'),'VALUE',@Table)) 

不知道是怎麼回事就在這裏

Answer 1

試試這個：

DECLARE @sSQL varchar(1000) 

SET @sSQL = @Select + ' WHERE ' + REPLACE(REPLACE(@Where,'CRITERIA','TABLE_NAME'),'VALUE',@Table) 

EXEC (@sSQL) 

我相信EXEC（）接受字符串變量或字符串常量，但不接受組合。
