Perform a Case insensitive Like query in a case sensitive SQL Server database

由 混江龙づ霸主 提交于 2021-02-07 13:38:55
问题 This is my scenario. SQL Server 2014 Standard edition, I have a database with a collation SQL_Latin1_General_CP437_BIN2 which is case sensitive.

I tried using Lcase , Ucase , but I am getting the error Msg 195, Level 15, State 10, Line 4

Getting BeautifulSoup to catch tags in a non-case-sensitive way

由 人盡茶涼 提交于 2021-02-07 08:36:30
问题 I want to catch some tags with BeautifulSoup: Some <p> tags, the <title> tag, some <meta> tags. But I want to catch them regardless of their case; I know that some sites do meta like this: <META> and I want to be able to catch that. I noticed that BeautifulSoup is case-sensitive by default. How do I catch these tags in a non-case-sensitive way? 回答1: You can use soup.findAll which should match case-insensitively: import BeautifulSoup html = '''<html> <head> <meta name="description" content=

How to make a CaseInsensitiveConcurrentMap?

由 倾然丶 夕夏残阳落幕 提交于 2021-02-04 17:14:47
问题 How can I implement class CaseInsensitiveConcurrentMap<V> implements ConcurrentMap<String , V> which works just like ConcurrentHashMap<String , V> except that the keys are compared case-insensitively? The keys should not be converted to lowercase or uppercase. Note that Collections.synchronizedMap(new TreeMap<String, new MyCaseInsensitiveComparator()) is no solution as it allows no concurrency and misses the additional methods. Creating a String-like class with case-insensitive equals and

Python case insensitive file name?

由 落爺英雄遲暮 提交于 2021-02-04 14:56:11
问题 I need to load a file given it's name, but the name I get is case insensitive. "A.txt" could actually be "a.txt". How to do this the fast way (not generate all possible names and try each)? 回答1: You could list the directory the file's in ( os.listdir ), and see if there are matches for your filename. The matching can be done by lower-casing both filenames and comparing. 回答2: You can't do it without taking a directory listing and taking both the item you're looking for and each in the

Gremlin case insensitive search

由 自作多情 提交于 2021-01-29 17:45:41

These vertices have a property "name" associated with them. I need to find out if there is a vertex that has a certain name. This check has to be case insensitive. Suppose I was to do this in a relational database, I could write the following query: SELECT * FROM device d WHERE LOWER(d.name) = 'mydevice' I am searching for a function similar to

How can I use automapper to map 2 enums that use different casing

由 我与影子孤独终老i 提交于 2021-01-28 20:33:18
问题 I have many enums that I want to keep all caps that I have to map to another system that has no standard at all (caps, no caps, pascal, camel). I can't find an automapper flag to tell it to ignore case for enums. I could use a custome converter for each enum but I would prefer a generic converter since there are so many. Some answers here have implied that automapper does this already. I don't get that from my testing. If I have these enums: public enum AllCaps { VALUE1, VALUE2, VALUE3 }
