由 青春壹個敷衍的年華 提交于 2019-12-02 19:53:56
Is it possible to combine the CASE statement and the LIKE operator in a MySQL SELECT statement? For Example, I am trying to query a database that stores data in a single column in either one of two formats (this is awful and hurts my head, but I cant change the data so it is what it is.). So sometimes the column numbers would have data like "6901xxxxxxxx" and sometimes it would have data like "91xxxxxxxxxxx". What I would like to do is query the data like so - SELECT CASE digits WHEN LIKE "6901%" THEN substr(digits,4) WHEN LIKE "91%" THEN substr(digits,2) END as "digits", FROM raw This

TSQL CASE with if comparison in SELECT statement

由 陌路散爱 提交于 2019-12-02 17:53:28
I would like to use CASE statement in SELECT. I select from user table, and (as one attribute) I also use nested SQL: SELECT registrationDate, (SELECT COUNT(*) FROM Articles WHERE userId = Users.userId) as articleNumber, hobbies, ... FROM USERS and then I would like to do a CASE statement to get rank of user (rank is dependent on articleNumber). I tried like this: SELECT registrationDate, (SELECT COUNT(*) FROM Articles WHERE Articles.userId = Users.userId) as articleNumber, ranking = CASE WHEN articleNumber < 2 THEN 'Ama' WHEN articleNumber < 5 THEN 'SemiAma' WHEN articleNumber < 7 THEN 'Good'

What are the different kinds of cases?

由 纵然是瞬间 提交于 2019-12-02 17:01:24
I'm interested in the different kinds of identifier cases, and what people call them. Do you know of any additions to this list, or other alternative names? myIdentifier : Camel case (e.g. in java variable names) MyIdentifier : Capital camel case (e.g. in java class names) my_identifier : Snake case (e.g. in python variable names) my-identifier : Kebab case (e.g. in racket names) myidentifier : Flat case (e.g. in java package names) MY_IDENTIFIER : Upper case (e.g. in C constant names) Nils von Barth Names are either generic, after a language, or colorful; most don’t have a standard name
