In the last example, the names are in quotes so their case is maintained. This means you’ll get a table called “Person” with two columns called “FullName” and “Address”. Now what happens if you try to run a query with a table called “Person”? Well, using SQL like this: S...
Under such circumstances, there comes the need forcase-insensitivequeries. The case-insensitive queries will return the search results without bothering about the case. Let’s see how can we query the case-insensitive queries in PostgreSQL. How to Write Case-Insensitive Queries in PostgreSQL? There ...
Additionally, you can set thesearch_pathas a switch to make the data case insensitive if you want only part of your application to behave like case insensitive without making any changes to the application. Drawbacks You need to add thesearch_path(with theutilschema beforepg_catalog) to the ...
Now yourusernamecolumn is case-insensitive and you don’t have to worry with anything else. But if you’re running an older version, you must use theactiverecord-postgresql-citextgem. Just add it to yourGemfileand runbundle install. source'https://rubygems.org'gem'rails','4.1.9'gem'pg'g...

Now what would be the correct result for the following query in a case-insensitive collation? 1 SELECT 'Fußball' LIKE 'FUS%'; You could argue that it should be TRUE, because that's what you'd get for upper('Fußball') LIKE 'FUS%'. On the other hand, 1 2 3 4 5 6 SE...
the system doesn’t even provide a hint as to what encoding to use or expect.) The collation function just compares strings byte-wise; this works great on ASCII, and is meaningless (even for equality!) on UTF-8 or UTF-16. For functions, like case conversion, that need to know a char...
* Otherwise, everything in the query is either parallel-safe or * parallel-restricted, and in either case it should be OK to impose * parallel-mode restrictions. If that ends up breaking something, then * either some function the user included in the query is incorrectly * labelled as ...
LikeWith the whereLike scope you can do case-(in)sensitive like comparisons between a column and a value.$query->whereLike($column, $value, $caseSensitive = false); $query->orWhereLike($column, $value, $caseSensitive = false);Between Symmetric...
Finally we made some small changes to the code to ensure queries automatically use ILIKE on PostgreSQL instead oflower(some_column)as ILIKE performs quite a bit better. On MySQL a regular LIKE is used as it's already case-insensitive. ...
