I need sql query to search correct user id from db even if its given in any format
select hr_id from users where hr_id LIKE '%\$user_ID %';
I want to delete user id ab123c
. If user provides aBc123C
with any case format it should search and find ab123c
itself from db, as the id provided will be unique.
the user ID can be AB12C , ab12c or 'ab12c ' any of them not sure. only the known thing is the alphabet and number provided in id will be in same sequence as provided and would be unique.
尝试这样的事情,如果您确定名称是唯一的,则将它们都转换为小写:
select hr_id from users where LOWER(hr_id) LIKE LOWER('%\$user_ID%');
You can try that:
SELECT hr_id FROM users WHERE hr_id LIKE '%\$user_ID %' COLLATE utf8_general_ci;
Or even:
SELECT hr_id FROM users WHERE LOWER(hr_id) LIKE LOWER('%\$user_ID %');
If you're using PostgreSQL:
SELECT hr_id FROM users WHERE hr_id ILIKE '%\$user_ID %';
Tell your shell user_ID is lowercase:
typeset -l user_ID
read user_ID
echo ${user_ID}
