MySQL select UTF-8 string with '=' but not with 'LIKE'
After seeing Marcus Adams' answer I realized that the REPLACE function could be the solution for this problem, although he didn't mentioned this function. As I have only two different combining characters (acute and tilde), combined with other ASCII characters, for example j with tilde, j with acute, m with...

How to apply a custom collation to specific columns of an SQLite database?

User-defined functions and collations are a feature of the ADO.NET driver, not the ORM that sits on top of it.

Is it ok to mix storage engines on same database?
mysql,opencart,collation,mariadb,storage-engines
Its OK if you know what you're doing and why you are doing it. Different engines use memory and disk storage very differently. For an OLTP type system InnoDB is usually more sensible than MyISAM (did you check the contention before trying a different engine?). But any memory you add...

SQL Server : collation set to insensitive is ignored
I found the solution! I found out that, collation has impact only for ordering. I'm using fulltext search so I need to change fulltext indexes. Here is how I did if anyone else need do the same.. IF EXISTS (SELECT 1 FROM sys.fulltext_indexes WHERE object_id = object_id('Product')) DROP FULLTEXT INDEX...
Using COLLATE on peewee queries
You can specify a collation by building up the SQL clause and passing it to order_by(). For example: collated = Clause(MyModel.field, SQL('COLLATE NOCASE')) MyModel.select().order_by(collated, MyModel.other_field) For the index unfortunately you will need to create that by hand as peewee does not know how to add collation information to the CREATE...
Danish letters MySQL output
If things are working in phpMyAdmin, but not on your own web pages, it's likely to be a problem with the character encoding of your web pages. Assuming you're using an HTML5 doctype, try just adding: <meta charset="utf-8"> to the <HEAD> section of your site. Basically, from your comments and...
SQL - “incrementing” a char value causes collation error
sql,sql-server,sql-server-2008,collation
From one of the comments, sounds like you may have already hit on this, but here's what I would recommend: UPDATE TABLE SET VALUE = CAST((CAST(VALUE AS INT) + 1) AS VARCHAR) OUTPUT inserted.VALUE WHERE NAME = 'SOME_NAME' This will output the new value like a SELECT statement does. You...

COLLATION is not valid for CHARACTER SET not corresponding to my settings
What is the datatype of kat.kategorie ? GROUP_CONCAT( kat.kategorie ORDER BY CONVERT(kat.kategorie USING utf8) COLLATE utf8_czech_ci ) You may also need a call to CAST(... AS CHAR). In the future, do not mix CHARACTER SETs. GROUP_CONCAT, and a couple of other functions that involve combining things, have a problem in...
Collation of mysql import differs when exec from php
php,mysql,bash,utf-8,collation
I assume your input file is encoded in utf8. If not, change the encodings below appropriately. Just a guess but maybe for scripts executed by PHP a wrong LANG is set or it is missing and the default is not utf-8. Try to set LANG explicitly in your import.sh: export...
Highlighting Search Results: RegEx Character Collation?
php,mysql,regex,collation,unicode-normalization
Here's what I ended up doing. Seems to have negligible impact on performance. (I noticed none!) First, a function that converts the query word into a regular expression iterating the variants: function iast_normalize_regex($str) { $subst = [ 'a|ā', 'd|ḍ', 'e|ӗ', 'h|ḥ', 'i|ī', 'l|ḷ|ḹ', 'm|ṁ|ṃ', 'n|ñ|ṅ|ṇ', 'r|ṛ|ṝ', 's|ś|ṣ', 't|ṭ', 'u|ū' ];...
Python MySQLdb change string encoding

I think that your MYSQLdb python library doesn't know it's supposed to encode to utf8 and is encoding to the default python system-defined charset latin1. When you connect() to your database, pass the charset='utf8' parameter. This should also make a manual SET NAMES...
Difference between database, table, column collation
MySQL's character sets and collations can be interpreted as a top-down list of prioritized items. The topmost is least priority and the bottommost is most priority. Order of precedence with topmost being least precedence: Server collation Connection-specific collation Database collation Table collation Column collation Query collation (using CAST or CONVERT)...
Char encoding and SQL in C#
c#,sql-server,character-encoding,collation
Apparently, "\xCA" is a non-breaking space on the Mac — the same as "\xA0" on Windows and in ISO-Latin-1, and " " in HTML. http://use.perl.org/use.perl.org/commentsf6b4-3.html?sid=18447&op=reply&threshold=0&commentsort=0&mode=thread So when using UTF-8 encoding it just knows that this is a nonsense char and can be skipped, so the strings are equal using (StreamReader...
Generic solution for SQL Server 2008 collation conflict issue
If you migrate a database by backing it up and restoring it, it will maintain its collation as well as the collation for all objects it contains, so that in itself will not cause a problem if you do it for all databases. If you migrate by scripting objects and...

Select statement returns nothing when column collation SQL_Latin1_General_CP1_CI_AS in T-sql
sql-server,collation,string-comparison
In T/SQL the string constant 'БHО' is an ANSI string, and 'Б' is not available so you'll get the question marks that @EduardUta queried. You need to work with Unicode strings, using the N prefix for string constants and nvarchar. Try this; SELECT Veri from tblTest where CAST(Veri COLLATE SQL_Latin1_General_CP1_CI_AS...

Collations are not working fine in Solr
solr,collation,spell-checking,search-suggestion
I got the answer of my question. After depth reading, I found the logic behind collations. 1) spellcheck.maxCollations: It just make collation candidates to test against the index. 2) spellcheck.maxCollationTries : It evaluates the collations that builds at the time of spellcheck.maxCollations. If we set the value of spellcheck.maxCollationTries low,...

Is it safe to change Collation on Postgres (keeping encoding)?
Perfectly safe -- the collation is just telling Postgres which set of rules to apply when sorting text. You can even set it dynamically on a query basis in the order by clause, and should be able to alter it without needing to dump the database....
