更換CHAR（0）NVARCHAR Latin1_General_CI_AS整理

在SQL Server中，我試圖取代CHAR(0)與''，但它不工作作爲我的領域其實是一個NVARCHAR場，我的整理是Latin1_General_CI_AS但是當我轉換爲SQL_Latin1_General_CP1_CI_AS它僅適用於VARCHAR而不是NVARCHAR。更換CHAR（0）NVARCHAR Latin1_General_CI_AS整理

SELECT val, REPLACE(val , CHAR(0), 'x') 
FROM (
     SELECT 'a' + CHAR(0) + 'b' AS val 
     ) AS X

返回a | a

SELECT val, REPLACE(CAST(val COLLATE SQL_Latin1_General_CP1_CI_AS AS varchar(100)), CHAR(0), 'x') 
FROM (
     SELECT 'a' + CHAR(0) + 'b' AS val 
     ) AS X

返回a | axb

SELECT val, REPLACE(CAST(val COLLATE SQL_Latin1_General_CP1_CI_AS AS varchar(100)), CHAR(0), 'x') 
FROM (
     SELECT CAST('a' + CHAR(0) + 'b' AS NVARCHAR(100)) AS val 
     ) AS X 
SELECT val, REPLACE(CAST(val COLLATE SQL_Latin1_General_CP1_CI_AS AS nvarchar(100)), CHAR(0), 'x')

返回a | axb

FROM (
     SELECT CAST('a' + CHAR(0) + 'b' AS NVARCHAR(100)) AS val 
     ) AS X 
SELECT val, REPLACE(CAST(val COLLATE SQL_Latin1_General_CP1_CI_AS AS varchar(100)), nCHAR(0), 'x')

返回a | a

FROM (
     SELECT CAST('a' + CHAR(0) + 'b' AS NVARCHAR(100)) AS val 
     ) AS X 
SELECT val, REPLACE(CAST(val COLLATE SQL_Latin1_General_CP1_CI_AS AS nvarchar(100)), nCHAR(0), 'x')

返回a | a

FROM (
     SELECT CAST('a' + CHAR(0) + 'b' AS NVARCHAR(100)) AS val 
     ) AS X

返回a | a

有，我可以''替換0x0000字符，而不是失去我NVARCHAR狀態

編輯方式：預期值爲a | axb爲最後一個查詢（或我類似但會支持NVARCHAR。

這也許[文章]（http://stackoverflow.com/questions/10451684/convert-char-columns-to-nvarchar-按順序改變代碼頁的語言enco）可能是一些幫助:) – bonCodigo

使用二進制整理條款，也沒有必要CAST

;WITH T 
    AS (SELECT CAST('a' + CHAR(0) + 'b' AS NVARCHAR(100)) AS val) 
SELECT val, 
     REPLACE(val COLLATE Latin1_General_100_BIN, nCHAR(0), 'x') 
FROM T
