Sql Server添加单引号

Posted 2020-10-19 Blogger

" \' "（单引号）的运用：在sql server中，两个" \' "(单引号)在拼接字符串的情况下运用，就是表示拼接上了一个" \' "单引号字符串。

SELECT TOP 1 \'\'\'\'+CONVERT(nvarchar(50),keyid)+\'\'\'\' name1 FROM Rel_ProductStockLock with (nolock) WHERE KeyId IS NOT NULL
SELECT TOP 1 \'\'\'\'+CONVERT(nvarchar(50),keyid)+\'\'\',\' name2 FROM Rel_ProductStockLock with (nolock) WHERE KeyId IS NOT NULL
SELECT \'\'\'\' name3;
SELECT \'123\'\'\' name4;
SELECT \'123\'+\'\' name5;
SELECT  \'"123"\' name6;
SELECT TOP 1 \'123\'+AreaName name7 FROM dbo.Dim_Area;
SELECT TOP 1 \'123\'\'\'+AreaName name8 FROM dbo.Dim_Area;
SELECT TOP 1 \'123\'\'\'+AreaName+\'\'  name9 FROM dbo.Dim_Area;
SELECT TOP 1 \'123\'\'\'+AreaName+\'\'\'\' name10 FROM dbo.Dim_Area;

SELECT TOP 3 \'\'\'\'+CONVERT(nvarchar(50),d.LpnId)+\'\'\'\', d.LpnId,r.sourcebarcode,* FROM dbo.Rel_ProductStockLock r (NOLOCK)
inner JOIN dbo.Fct_ProductStockDetail d(NOLOCK) ON r.KeyId=d.ProductStockDetailId
