collation

问题 Total NOOB trying to solve this error. I recently switched servers and suddenly a table / sql query which used to work perfectly is now displaying the following error: Illegal mix of collations (utf8_general_ci,IMPLICIT) and (latin1_swedish_ci,NUMERIC) for > operation '<>' SQL=SELECT... I have a structure in the table which includes TIME fields and INT fields. When I switch the time field datatype to INT and not TIME the error disappears. Unfortunately so does the time data (it displays 0:00)

问题 In a C# application that uses iBATIS.NET to map data to an SQLite database I want to be able to sort specific columns by an alphabet that slightly differs from the English alphabet (there are some special characters and the order of some characters is different). I want to get from the database the results that are already sorted, because sorting in the application itself is impossible due to pagination. After some research I concluded that applying a custom collation may be the only option

问题 I have 2 table and I want to do join those tables. But one table collation is utf8_turkish_ci another is utf8_general_ci . These tables are big (2.9GB / 550MB) So I don't want to use " COLLATION " keyword in query because it's decelerated to my query. My question is: if I change the table COLLATION from utf8_turkish_ci To utf8_general_ci so garble or change any character in rows? Thanks 回答1: Collation changing do not change characters. The collation is a rule (or rules) which say how to

问题 I need to make a get query like: obj = Current.objects.get(Code='M01.C0001') But the query giving "Multiple Objects Returned' error because of the database has another record with similar unicode string 'M01. Ç 0001' [<obj: M01.Ç0001>, <obj: M01.C0001>] I try to fetch data with field lookup functions, but it does not work anyway. I googled around but I didn't find a way to temporarily set the Collation for this query. Is it possible to temporarily set collation during executing a get query in

问题 I'm an IT consultant that usually manages hardware and networks but our programmers are on leave at the moment. I've made some modifications to a MSSQL query that runs over two databases on each of our 15 site's Practice Management Software servers and I'm getting an error on a few of the servers relating to a collation conflict. On most of our site's servers it runs fine, but there is 4 out the 15 servers that appear two have the databases using different collation for some reason. I've

问题 I have created some new databases in SQL Server 2008 Express (10.0.1600.22) and I have also restored one from SQL Server 2005 Express (9.00.1399.06). The collations for these are different and I cannot execute queries across them as a result. So I am trying to change the restored database collation from: SQL_Latin1_Genral_CP1_CI_AS to: Latin1_General_CI_AS However the new collation does not appear in the list of options. Not sure if this is possible. BTW - workarounds that are not options: I

问题 I was granted with the beautiful task ;-) to design some tables in a MySQL Database which should hold human names. Criteria: I have only the full names. (There is no separation for e.g. prename, surname and so on) The storage should be diacritic sensitive. (The following names stand for different persons) "Voss" and "Voß". "Joel" and "Joël". "franc" and "Franc" and "Fránc". A search should return all similar names to the search string: E.g: Search for "franc" should return ["franc", "Franc",
