SQL Server automatically generates phonetic first letter functions _mssql

Create a query that executes the following statement generation function fn_getpy

Copy Code code as follows:

--Generate phonetic first code
CREATE function fn_getpy (@str nvarchar (4000))
Returns nvarchar (4000)
--with encryption
As
Begin
DECLARE @intLen int
declare @strRet nvarchar (4000)
declare @temp nvarchar (100)
Set @intLen = Len (@str)
Set @strRet = '
While @intLen > 0
Begin
Set @temp = '
Select @temp = case
When substring (@str, @intLen, 1) >= ' 帀 ' Then ' Z '
When substring (@str, @intLen, 1) >= ' ya ' Then ' Y '
When substring (@str, @intLen, 1) >= ' XI ' then ' X '
When substring (@str, @intLen, 1) >= ' 屲 ' Then ' W '
When substring (@str, @intLen, 1) >= ' he ' then ' T '
When substring (@str, @intLen, 1) >= ' sa ' then ' S '
When substring (@str, @intLen, 1) >= ' 呥 ' Then ' R '
