collation

问题 my output after code below is: " PHP Fatal error: Class 'Collator' not found ". I've read in php manual that for COLLATOR class , PHP version needs to be PHP 5 >= 5.3.0. My PHP version is 5.3.24. in my phpinfo() I searched 'coll' string but nothing is found. also please note that my site lang is Turkish and I am using UTF-8 So what is the reason for my fatal error output? Thanks. /* fetch values */ $etiket_bulutu = ''; while ($beyan->fetch()) { $etiket_bulutu .= $tags.', '; } $etiket_bulutu =

问题 I'm storing responses from the google geocoded into my database. One such response has an accent mark over the o. The town is Rincon. (I would put the accent mark here to show you, but I don't know how.) When the response is stored into my mySQL database it looks like this: Rincón I realize that this has to do with Collation, but I'm nervous about making changes to the database because I have so much data in there. The Collation that is currently applied to this field is utf8_general_ci. Can

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 want to perform a LIKE query which should return the output irrespective of case sensitive. Ex: if i execute a Like query to fetch the records with userName 'John' it should also return rows irrespective of case sensitive 'JOHN', 'John', 'john','joHN'. I tried using Lcase , Ucase , but I am getting the error Msg 195, Level 15, State 10, Line 4

问题 I get the following error: Illegal mix of collations (latin1_swedish_ci,COERCIBLE) and (utf8_general_ci,IMPLICIT) for operation 'find_in_set' This is the query I was trying to execute: SELECT ID FROM xs_user_profiles WHERE ID='' AND FIND_IN_SET('1',site_structure); I looked up the properties of this table and it has charset utf8 and collation utf8_general_ci. This works well with all my sites so I am not sure what's going wrong. 回答1: If you are using mysqli , issue this command right after

问题 I want to customize ICU Collation of Postgres server in my windows machine. so I created a new collation using: CREATE COLLATION digitslast (provider = icu, locale = 'ja-u-kr-latn-digit'); and expected as below. ex) # select code from table order by code collate "digitslast"; code | -----+-- a | ... A | ... 1 | ... ... | ... But result has the same order as the default order. code | -----+-- 1 | ... a | ... A | ... ... | ... Is this possible? And is there some mistake? 来源： https:/

问题 I am copying data from MySQL to SQL Server using a linked server. SELECT comment FROM openquery(my_linked_server, 'SELECT comment FROM search_data'); The text in the MySQL table column is xxx 🤘 xxx . By time I receive it in SQL Server it is xxx 🤘 xxx . The MySQL table is utf8mb4 , and I have set up the ODBC config for the linked server to use this. I am using MySQL ODBC 5.3.13 Any advice would be appreciated. the SQL Server version is 2016, I have seen examples to put do select N'🤘' etc,

问题 I know that having a different column collation impacts table performance, but I haven't been able to find any information on performance difference between table collations. Also, what if I don't have any varchar/etc. type columns in my table, in that case does it even matter what collation is my table set to? If so what's the most robust collation to have for a table that contains only number column types? 回答1: The table character set and collation are used as default values for column

问题 I am on MySQL 5.6.22 (InnoDB) on Amazon RDS. I have attempted to set all of my tables, columns, connection and database charset and collation settings to utf8mb4 / utf8mb4_unicode_ci. I can find no evidence anywhere that anything has charset latin1 , yet when I execute the following code (either via node-mysql, or directly in "Sequel Pro" app on my Mac): update MyTable m set m.Column8 = 1 where m.Column3 = 26 and m.Column4 = 76 collate utf8mb4_unicode_ci I get this error message: COLLATION

问题 I'm attempting to move a SQL Server DB which is used by a C# application (+EF6) to Postgres 12 but I'm not having much luck with getting case-insensitive string comparisons working. The existing SQL Server db uses SQL_Latin1_General_CP1_CI_AS collation which means all WHERE clauses don't have to worry about case. I understand that CIText was the way to do this previously, but is now superseded by non-deterministic collations. I created such a collation; CREATE COLLATION ci (provider = icu,
