我想在包含多个单词的长句子上使用SOUNDEX()和函数。DIFFERENCE()到目前为止，我发现这两个功能都适用于单个单词。例如：

"Stackoverflow is a very good website"

如果我使用DIFFERENCE("Stackoverflow is a very good website")，它只会匹配句子第一个单词的差异，即“stackoverflow” - 但不匹配其余单词。我实际上是在尝试在 SQL 中构建一个拼写建议查询，如果我们输入错误，谷歌会向我们显示正确的拼写。

请帮忙。

这是我的代码：

DECLARE @Sound1 AS VARCHAR(4)
DECLARE @Sound2 AS VARCHAR(4)
DECLARE @Equals AS BIT
DECLARE @str1 AS VARCHAR(50)
DECLARE @str2 AS VARCHAR(50)
DECLARE @Difference AS INTEGER

SET @str1 = 'Stackoverflow is a very good website'
SET @str2 = 'Stackovxxflow'
SET @Sound1 = SOUNDEX(@str1) 
SET @Sound2 = SOUNDEX(@str2) 


IF(@Sound1 <> @Sound2)
BEGIN
    SET @Difference = DIFFERENCE(@str1, @str2)
    IF(@Difference <= 4)
    BEGIN
        SELECT TOP 1 [Address] FROM _Employee
        ORDER BY DIFFERENCE([Address],@str2) DESC
    END
END
