Question

我的表格包含lastName

的字段UNICODE

我需要实现SOUNDEX功能，但它不会起作用，因为它只需要latin。所以我尝试将其转换为latin但仍然得到相同的错误only latin letters allowed

这是我试过的

SEL * 
FROM tab_test
WHERE SOUNDEX(REGEXP_REPLACE(lastName, '[^A-Z]', '')) = 'smith' 



SEL * 
FROM tab_test
WHERE SOUNDEX(TRANSLATE(lastNameUSING unicode_to_latin)) = 'smith'

如何更正问题

编辑

这就是我所尝试的，正如dnoeth所暗示的那样。但它仍然无效

     SEL * 
     FROM tab_test
     WHERE SOUNDEX(TRANSLATE(REGEXP_REPLACE(
     lastName,'[^a-zA-Z]','') USING   
     UNICODE_TO_LATIN))  = 's530'

以下是无效的查询

 SEL  lastName, REGEXP_REPLACE(lastName, '[^a-zA-Z]', '') lastName_regex 
 FROM (SEL * 
 FROM tab_test
 WHERE personId < 10 
 ) der 
 WHERE SOUNDEX(REGEXP_REPLACE(lastName, '[^a-zA-Z]', '')) = 's530'

REGEXP子查询的结果如下

SEL  lastName, REGEXP_REPLACE(lastName, '[^a-zA-Z]', '') lastName_regex 
 FROM (SEL * 
 FROM tab_test
 WHERE personId < 10 
 ) der

结果直接从teradata sql assistant

复制

    LASTNAME    lastName_regex
1   Smith                   Smith              
2   Smith                   Smith              
3   Smith                   Smith              
4   Smith                   Smith              
5   Smith                   Smith              
6   Smith                   Smith              
7   Smith                   Smith              
8   Smith                   Smith

Answer 1

你的正则表达式也删除了小写的a到z。

所以试试

REGEXP_REPLACE(lastName, '[^a-zA-Z]', '') -- explicitly add lowercase

或

REGEXP_REPLACE(lastName, '[^A-Z]', '',1,0,'i')) -- do a case insensitive comparison

顺便说一下，SOUNDEX('smith')的结果不是'史密斯'，而是's530'。

尝试使用UNICODE_TO_LATIN和ERROR

如何在Teradata中将unicode转换为拉丁语？
