SQL2005CLR函数扩展-繁简转换

news 来源：原创 2024/5/20 1:27:37

这个方法比较简单，用Microsoft.VisualBasic命名空间下强大的字符串处理函数就可以了

c#代码如下，编译为BigConvertor.dll

using System;

using System.Data.SqlTypes;

using Microsoft.SqlServer.Server;

public partial class UserDefinedFunctions

{

[Microsoft.SqlServer.Server.SqlFunction ]

public static SqlString BigToGB(SqlString inString)

{

if (inString.IsNull) return SqlString .Null;

return (Microsoft.VisualBasic.Strings .StrConv(inString.Value, Microsoft.VisualBasic.VbStrConv .SimplifiedChinese, 0));

}

[Microsoft.SqlServer.Server.SqlFunction ]

public static SqlString GBToBig(SqlString inString)

{

if (inString.IsNull) return SqlString .Null;

return (Microsoft.VisualBasic.Strings .StrConv(inString.Value, Microsoft.VisualBasic.VbStrConv .TraditionalChinese, 0));

}

};

部署代码如下

CREATE ASSEMBLY BigConvertor FROM 'E:\sqlclrdata\BigConvertor.dll' WITH PERMISSION_SET = UnSAFE;

CREATE FUNCTION dbo. xfn_BigToGB

(

@value nvarchar ( max )

)

RETURNS nvarchar ( max )

AS EXTERNAL NAME BigConvertor. UserDefinedFunctions. BigToGB

CREATE FUNCTION dbo. xfn_GBToBig

(

@value nvarchar ( max )

)

RETURNS nvarchar ( max )

AS EXTERNAL NAME BigConvertor. UserDefinedFunctions. GBToBig

测试代码如下

LeetCode -- Minimum Size Subarray Sum

LeetCode -- Number of 1 Bits

对象属性拷贝(全匹配拷贝)

LeetCode -- Reorder List
