非字母字符

Question

我有一個t-sql腳本可以提取我們網站的成員，但是我在使用*，&或用戶名中有數字的用戶遇到問題。

我有例如以下數據：

''Dream A Little Dream'' 
***Unique Business Card/Sign/Logo Designs*** 
3D Visual Creations 
50dollarbanner.com 
etc.. 

我沿着頁面和用戶的頂部的英文字母可以點擊「A」，例如，它列出了所有的用戶開始用「 A」是有辦法也許再拍爲‘0’，例如，它會列出所有成員開始用數字或奇怪的字符：

這裏是我的測試腳本：

DECLARE @TotalPages INT 
DECLARE @UserName varchar(50) 
DECLARE @PG INT 
DECLARE @PageSize INT 
SET @UserName = 'Z' 
SET @PG = 1 
SET @PageSize = 70 
BEGIN 
    SELECT @TotalPages = COUNT(*)/@PageSize 
    FROM Member 
    WHERE (sbuser.sf_GetDisplayName(FirstName, LastName, BusinessName, DisplayNameTypeID) LIKE @UserName + '%') 
    AND UserName IS NOT NULL; 

    WITH FindSBMembers AS 
    (
     SELECT ROW_NUMBER() OVER(ORDER BY Claimed DESC, sbuser.sf_MemberHasAvatar(MemberID) DESC) AS RowNum, 
     MemberID,            -- 1 
     UserName,            -- 2 
     PrCity,             -- 3 
     PrStateID,            -- 4 
     sbuser.sf_MemberHasImages(MemberID) AS MemberHasImages, -- 5 
     sbuser.sf_MemberHasVideo(MemberID) AS MemberHasVideo, -- 6 
     sbuser.sf_MemberHasAudio(MemberID) AS MemberHasAudio, -- 7 
     sbuser.sf_GetDisplayName(FirstName, LastName, BusinessName, DisplayNameTypeID) AS DisplayName,   -- 8 
     ProfileTypeID,           -- 9 
     Zip,             -- 10 
     PhoneNbr,            -- 11 
     PrPhone,             -- 12 
     Claimed,             -- 13 
     @TotalPages AS TotalPages,        -- 14 
     City              -- 15 
     FROM Member 
     WHERE (sbuser.sf_GetDisplayName(FirstName, LastName, BusinessName, DisplayNameTypeID) LIKE @UserName + '%') 
     AND UserName IS NOT NULL 
     -- AND MemberID <> @MemberID 
    ) 
    SELECT * 
    FROM FindSBMembers 
    WHERE RowNum BETWEEN (@PG - 1) * @PageSize AND @PG * @PageSize 
    ORDER BY Claimed DESC 
END 

以下是包含腳本的詳細信息：

set ANSI_NULLS ON 
set QUOTED_IDENTIFIER ON 
GO 

ALTER FUNCTION [sbuser].[sf_GetDisplayName](
@FirstName varchar(50), 
@LastName varchar(50), 
@BusinessName varchar(50), 
@DisplayNameTypeID int) 
RETURNS varchar(150) WITH schemabinding 

AS 

BEGIN 
DECLARE @OUT varchar(150) 
SET @OUT = '' 
SET @FirstName = UPPER(LEFT(LTRIM(RTRIM(@FirstName)), 1)) + RIGHT(LTRIM(RTRIM(@FirstName)), LEN(LTRIM(RTRIM(@FirstName))) - 1) 
SET @LastName = UPPER(LEFT(LTRIM(RTRIM(@LastName)), 1)) + RIGHT(LTRIM(RTRIM(@LastName)), LEN(LTRIM(RTRIM(@LastName))) - 1) 
SET @BusinessName = UPPER(LEFT(LTRIM(RTRIM(@BusinessName)), 1)) + RIGHT(LTRIM(RTRIM(@BusinessName)), LEN(LTRIM(RTRIM(@BusinessName))) - 1) 
IF @DisplayNameTypeID = 2 -- FIRST/LAST NAME 
    BEGIN 
     SET @OUT = @LastName + ', ' + @FirstName 
    END 
IF @DisplayNameTypeID = 3 -- FIRST NAME/LAST INITIAL 
    BEGIN 
     SET @OUT = @FirstName + ' ' + LEFT(@LastName,1) + '.' 
    END 
IF @DisplayNameTypeID = 4 -- BUSINESS NAME 
    BEGIN 
     SET @OUT = @BusinessName + '' 
    END 
RETURN @OUT 
END 

非常感謝您的幫助。

Answer 1

如果您要包括所有非字母startcharacters條目提供的輸入參數@UserName爲「0」，那麼你可以嘗試類似的WHERE子句如下（未測試）？

這將讓你有一個「其它」類別，你可以通過調用程序與@UserName =「0」

WHERE (  
      ( sbuser.sf_GetDisplayName(FirstName, LastName, BusinessName, 
            DisplayNameTypeID) LIKE @UserName + '%' 
      )   
     OR 
      (
       PatIndex(‘[^A-Za-z]%‘, 
        sbuser.sf_GetDisplayName(FirstName, LastName, BusinessName, 
              DisplayNameTypeID) > 0 ) 
       AND 
       @UserName = '0' 
      )   
     ) 
     AND UserName IS NOT NULL 

Answer 2

使用這樣的事情在一開始（查詢之前檢索，即使用@UserName）：

IF @UserName = '0' SET @UserName = '[^a-z]'; 

如果你的排序規則是大小寫敏感的，那麼也許你應該使用'[^A-Za-z]'代替。
