Question

我有一个SQL查询从数据库中提取客户名称，创建一个具有该名称的客户文件夹。在查询中，我正在查杀斜杠和句点，我也将包含MCDONALD的任何结果更改为SIMPLY“MCDONALDS”。所以MCDONALDS＃123就像MCDONALDS一样出现。这是我的询问。

SELECT 
    CASE WHEN CHARINDEX('MCDONALD', cust_name) = 0
        THEN REPLACE(REPLACE([cust_name],'.',''),'--','-')
        ELSE 'MCDONALDS'
    END  cust_name
FROM job,dbo.cust cust_name
WHERE job.cust_id_bill_to = cust_name.cust_code AND
job.job_id = '44321' AND
job.sub_job_id = '2'

所以，结果现在是：

MCDONALDS,
BRISTOL-MYERS,
TRUMP-CASINO

期望的结果是每个单词的大写和小写..像这样：

Mcdonalds,
Bristol-Myers,
Trump-Casino

我知道这很简单，但对我而言，如何让它与我的查询的其余部分一起工作，到目前为止，我正在努力工作。

DELIMITER $$

DROP FUNCTION IF EXISTS `test`.`initcap`$$

CREATE FUNCTION `initcap`(x char(30)) RETURNS char(30) CHARSET utf8
BEGIN
SET @str='';
SET @l_str='';
WHILE x REGEXP ' ' DO
SELECT SUBSTRING_INDEX(x, ' ', 1) INTO @l_str;
SELECT SUBSTRING(x, LOCATE(' ', x)+1) INTO x;
SELECT CONCAT(@str, ' ', CONCAT(UPPER(SUBSTRING(@l_str,1,1)),LOWER(SUBSTRING(@l_str,2)))) INTO @str;
END WHILE;
RETURN LTRIM(CONCAT(@str, ' ', CONCAT(UPPER(SUBSTRING(x,1,1)),LOWER(SUBSTRING(x,2)))));
END$$

DELIMITER ;

用法：

选择initcap（'这是测试字符串'）;

对于Sql Server，您可以使用this

INITCAP用户定义的功能代码

IF OBJECT_ID('dbo.InitCap') IS NOT NULL
    DROP FUNCTION dbo.InitCap;
  GO

 CREATE FUNCTION dbo.InitCap (@inStr VARCHAR(8000))
  RETURNS VARCHAR(8000)
  AS
  BEGIN
    DECLARE @outStr VARCHAR(8000) = LOWER(@inStr),
         @char CHAR(1), 
         @alphanum BIT = 0,
         @len INT = LEN(@inStr),
                 @pos INT = 1;        

    -- Iterate through all characters in the input string
    WHILE @pos <= @len BEGIN

      -- Get the next character
      SET @char = SUBSTRING(@inStr, @pos, 1);

      -- If the position is first, or the previous characater is not alphanumeric
      -- convert the current character to upper case
      IF @pos = 1 OR @alphanum = 0
        SET @outStr = STUFF(@outStr, @pos, 1, UPPER(@char));

      SET @pos = @pos + 1;

      -- Define if the current character is non-alphanumeric
      IF ASCII(@char) <= 47 OR (ASCII(@char) BETWEEN 58 AND 64) OR
      (ASCII(@char) BETWEEN 91 AND 96) OR (ASCII(@char) BETWEEN 123 AND 126)
      SET @alphanum = 0;
      ELSE
      SET @alphanum = 1;

    END

   RETURN @outStr;         
  END
  GO

测试：

SELECT dbo.InitCap('new york');

结果：纽约

查询

SELECT 
    dbo.InitCap(CASE WHEN CHARINDEX('MCDONALD', cust_name) = 0
                    THEN REPLACE(REPLACE([cust_name],'.',''),'--','-')
                    THEN 'MCDONALDS'
               END)  cust_name
FROM job,dbo.cust cust_name
WHERE job.cust_id_bill_to = cust_name.cust_code AND
job.job_id = '44321' AND
job.sub_job_id = '2'

将案例改为Upper＆amp;在SQL Query SELECT中降低
