collation

问题 This question "Need a case insensitive collation where ss != ß" solves it for varchar type column, but mine has to be nvarchar . As far as I can gather, SQL_Latin1_General_Cp437_BIN differentiates between ß and ss . But it is also case-sensitive. Mine is a primary key column which also needs to be case INsensitive: I need e.g. weiß / Weiß to be considered equal, and also weiss / Weiss , but NOT weiß / weiss nor Weiß / Weiss nor weiß / Weiss etc. I've searched a lot for this, and is it really

问题 I have a list of words and want to find which ones already exist in the database. Instead of making tens of SQL queries, I decided to use "SELECT word FROM table WHERE word IN(array_of_words)" and then loop through the result. The problem is database collation. http://www.collation-charts.org/mysql60/mysql604.utf8_general_ci.european.html There are many different characters, which MySQL treats as the same. However, in Ruby code string1 would not be equal to string2. For example: if the word

问题 I have SQL Server on hosting, clients are mobile applications. I have logic that user creates data and store it on server. Some of the data is text. However user can enter english, hebrew or any other languages his client supports. Which Collation I need to specify to the tables to support all languages? Regards Yoav 回答1: you need to store it as nvarchar and make sure to prefix the text with N example declare @n nchar(1) set @n = N'文' select @n GO declare @n nchar(1) set @n = '文' select @n

问题 After a lot of reading and experimentation, it seems like I want PRIMARY strength for searching, but TERTIARY or IDENTICAL for ordering. Main question: Is that possible to achieve with H2 (or any other DB)? Secondary question: Am I the only one here or would any of you also like the above combination? Some confirmation would be helpful for my sanity. Background: It seems like the collation can only be set at the very beginning when creating the database. So I want to make sure to pick the

问题 I'm installing a new SQL Server 2008 server and are having some problems getting any usable information regarding different collations. I have searched SQL Server BOL and google'ed for an answer but can't seem to be able to find any usable information. What is the difference between the Windows Collation "Finnish_Swedish_100" and "Finnish_Swedish" ? I suppose that the "_100" -version is a updated collation in SQL Server 2008, but what things have changed from the older version if that is the

问题 The cmp operator works on code numbers, or at least that's what I think it does because the docs aren't explicit on that and don't mention any localization stuff. Can I make it sort by other collations? I know I tell sort how to compare, but I figure it must be in there already (somewhere). 回答1: Collation is available as an experimental feature: my @list = <a ö ä Ä o ø>; say @list.sort; # (a o Ä ä ö ø) use experimental :collation; say @list.collate; # (a ä Ä o ö ø) $*COLLATION.set(:tertiary

问题 I have read the following from Collator's Javadoc. "The exact assignment of strengths to language features is locale dependant. For example, in Czech, "e" and "f" are considered primary differences, while "e" and "ê" are secondary differences, "e" and "E" are tertiary differences and "e" and "e" are identical." Does this mean that I should set the STRENGTH based on the language I am using? If so can someone suggest the defaults for the locales: us_en, us_es, ca_fr, spain_spanish, chile
