SQL server ignore case in a where expression

由 不羁的心 提交于 2019-11-26 19:44:29
How do I construct a SQL query (MS SQL Server) where the "where" clause is case-insensitive? SELECT * FROM myTable WHERE myField = 'sOmeVal' I want the results to come back ignoring the case In the default configuration of a SQL Server database, string comparisons are case-insensitive. If your database overrides this setting (through the use of an alternate collation), then you'll need to specify what sort of collation to use in your query. SELECT * FROM myTable WHERE myField = 'sOmeVal' COLLATE SQL_Latin1_General_CP1_CI_AS Note that the collation I provided is just an example (though it will

PostgreSQL: Case insensitive string comparison

由 放肆的年华 提交于 2019-11-26 19:26:41
问题 Is there a simple ignore-case-comparison for PostgreSQL? I want to replace: SELECT id, user_name FROM users WHERE lower(email) IN (lower('adamB@a.com'), lower('eveA@b.com')); With something like: SELECT id, user_name FROM users WHERE email IGNORE_CASE_IN ('adamB@a.com', 'eveA@b.com'); The like and ilike operators work on single values (e.g. like 'adamB@a.com' ), but not on sets. 回答1: First, what not to do, don't use ilike... create table y ( id serial not null, email text not null unique );

django-orm case-insensitive order by

问题 I know, I can run a case insensitive search from DJango ORM. Like, User.objects.filter(first_name__contains="jake") User.objects.filter(first_name__contains="sulley") User.objects.filter(first_name__icontains="Jake") User.objects.filter(first_name__icontains="Sulley") And also, I can fetch them as user_list = User.objects.all().order_by("first_name") # sequence: (Jake, Sulley, jake, sulley) user_list = User.objects.all().order_by("-first_name") # for reverse # sequence: (sulley, jake, Sulley,

Can PHP's glob() be made to find files in a case insensitive manner?

由 半腔热情 提交于 2019-11-26 17:28:45
问题 I want all CSV files in a directory, so I use glob('my/dir/*.CSV') This however doesn't find files with a lowercase CSV extension. I could use glob('my/dir/*.{CSV,csv}', GLOB_BRACE); But is there a way to allow all mixed case versions? Or is this just a limitation of glob() ? 回答1: Glob patterns support character ranges: glob('my/dir/*.[cC][sS][vV]') 回答2: You could do this $files = glob('my/dir/*'); $csvFiles = preg_grep('/\.csv$/i', $files); 回答3: glob('my/dir/*.[cC][sS][vV]') should do it.

Case insensitive std::string.find()

由 安稳与你 提交于 2019-11-26 17:27:50
问题 I am using std::string 's find() method to test if a string is a substring of another. Now I need case insensitive version of the same thing. For string comparison I can always turn to stricmp() but there doesn't seem to be a stristr() . I have found various answers and most suggest using Boost which is not an option in my case. Additionally, I need to support std::wstring / wchar_t . Any ideas? 回答1: You could use std::search with a custom predicate. #include <locale> #include <iostream>

Case insensitive comparison of strings in shell script

由 旧城冷巷雨未停 提交于 2019-11-26 17:27:34
问题 The == operator is used to compare two strings in shell script. However, I want to compare two strings ignoring case, how can it be done?

case-insensitive list sorting, without lowercasing the result?

由 戏子无情 提交于 2019-11-26 16:13:56
I have a list of strings like this: ['Aden', 'abel'] I want to sort the items, case-insensitive. So I want to get: ['abel', 'Aden'] But I get the opposite with sorted() or list.sort() , because uppercase appears before lowercase. How can I ignore the case? I've seen solutions which involves lowercasing all list items, but I don't want to change the case of the list items. The following works in Python 2: sorted_list = sorted(unsorted_list, key=lambda s: s.lower()) It works for both normal and unicode strings, since they both have a lower method. In Python 2 it works for a mix of normal and

Case insensitive string replacement in JavaScript?

由 本秂侑毒 提交于 2019-11-26 15:19:18
I need to highlight, case insensitively, given keywords in a JavaScript string. For example: highlight("foobar Foo bar FOO", "foo") should return "<b>foo</b>bar <b>Foo</b> bar <b>FOO</b>" I need the code to work for any keyword, and therefore using a hardcoded regular expression like /foo/i is not a sufficient solution. What is the easiest way to do this? (This an instance of a more general problem detailed in the title, but I feel that it's best to tackle with a concrete, useful example.) okoman You can use regular expressions if you prepare the search string. In PHP e.g. there is a function
