如何插入行重視

與價值觀如何插入行重視

CREATE TABLE #tbl 
    (
     id int identity(1,1), 
     object_type int , 
     object_id nvarchar(50), 
     refl nvarchar(4000) 
    )

REFL值有這樣參數應用表：

<prov><CProv><object_type>1</object_type><object_id>152</object_id></CProv></prov> 
<prov><CProv><object_type>0</object_type><object_id>150</object_id></CProv></prov> 
<prov><CProv><object_type>0</object_type><object_id>156</object_id></CProv></prov> 
<prov><CProv><object_type>1</object_type><object_id>172</object_id></CProv></prov>

我想選擇所有的數據至極是REFL另一個值declare @val nvarchar(4000)。這可能嗎？當我嘗試select @val = refl from #tbl它只選擇最後一行，我想選擇所有行。它怎麼樣？它必須像

@val = N'<prov><CProv><object_type>1</object_type><object_id>152</object_id></CProv></prov> 
    <prov><CProv><object_type>0</object_type><object_id>150</object_id></CProv></prov> 
    <prov><CProv><object_type>0</object_type><object_id>156</object_id></CProv></prov> 
    <prov><CProv><object_type>1</object_type><object_id>172</object_id></CProv></prov>'

你的意思是說有4分排在#tbl表？ – DarkKnight

@HardCoreProgrammer是有4行 – GeoVIP

試試這個

DECLARE @val NVARCHAR(4000) 
SELECT @val = COALESCE(@val + '', '') + refl 
FROM #tbl 

SELECT @val

非常感謝您節省我的時間 – GeoVIP

使用T-SQL split function，然後說

WHERE refl in IN yourSplitFunction(@val)
