'REPLACE'附近的語法不正確

Question

以下SQL語句顯示了PRINT但使用EXEC的可靠結果，使我在'REPLACE'附近的語法不正確

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))

不知道這是怎么回事

Answer 1

嘗試這個：

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。
