I don't do too much SQL so need help with something simple.
我没有做太多SQL,所以需要简单的帮助。
I have the following Table
:
我有以下表格:
ID term value
--------------
1 term1 slug/
2 term1 slug/
3 term2 something/something
4 term2 slug/
5 term3 slash-/-something
What I want to do is to FIND /
in column value
and REPLACE with an empty string BUT only where term
is equal to term1
我想要做的是查找/列值和使用空字符串REPLACE但仅限于term等于term1
The result would be:
结果将是:
ID term value
--------------
1 term1 slug
2 term1 slug
3 term2 something/something
4 term2 slug/
5 term3 slash-/-something
I can SELECT everything in term
that is equal to term1
, and I can FIND AND REPLACE everything in value
with a /
, but I can't seem to figure out how to combine the two operations together.
我可以在术语中选择等于term1的所有内容,并且我可以使用/来查找和替换值中的所有内容,但我似乎无法弄清楚如何将这两个操作组合在一起。
Note: I recognize there's no FIND AND REPLACE operation.
注意:我认识到没有FIND AND REPLACE操作。

You just need to execute an Update
command in the database:
您只需在数据库中执行Update命令:
update yourTableNameHere
set value = replace(value, '/','')
where term = 'term1'
#2

Try this :
尝试这个 :
SELECT ID, term, CASE WHEN term = 'term1' THEN REPLACE(value, '/','')
ELSE value
END AS value
FROM tablename
