Answer 1

它看起来不是很好，但它有效。它从字符串中删除任何数字

SELECT
    REPLACE( REPLACE( REPLACE( REPLACE( REPLACE( REPLACE (
    REPLACE( REPLACE( REPLACE( REPLACE('Hallo_1234567890_99','0','')
    ,'1',''),'2',''),'3',''),'4',''),'5',''),'6',''),'7',''),'8',''),'9','');


update Actress 
SET name  = REPLACE( REPLACE( REPLACE( REPLACE( REPLACE( REPLACE (
        REPLACE( REPLACE( REPLACE( REPLACE(name,'0','')
        ,'1',''),'2',''),'3',''),'4',''),'5',''),'6',''),'7',''),'8',''),'9','');

如果您使用 MariaDB，您可以使用 REGEX_REPLACE：

update Actress
 set name =  REGEXP_REPLACE(name,'[0-9]','');

样本

MariaDB [(none)]> SELECT REGEXP_REPLACE('A1B2C44','[0-9]','');
+--------------------------------------+
| REGEXP_REPLACE('A1B2C44','[0-9]','') |
+--------------------------------------+
| ABC                                  |
+--------------------------------------+
1 row in set (0.00 sec)
