Force binary collation option is enabled. By default, SQL Data Compare uses the collation of a column to decide whether or not to compare data case-sensitively. Most SQL Server databases default to a case-insensitive collation, but this can be overridden using the Force binary collation option in SQL Data Compare. Feb 10, 2015 · PostgreSQL has an extension called citext. The citext extension The citext extension allows you to define insensitive-case columns, so you can avoid things like the lower function.

  1. Jan 23, 2015 · I always wonder why case insensitive indexes and comparations are no first class citizens in PostgreSQL. Of course we can use citext, but it is a contrib module and now we have a good example that some great new features are not available to those of us who need case insensitive collations. Now we have year 2016.

  6. PostgreSQL, unlike MySQL, treats strings as case sensitive in all circumstances. This includes comparison with = and LIKE collision detection in unique indexes Usually this is fine, but some strings (like emails and usernames) should typically be treated as case insensitive. There are a few wor...
  7. The approach is to create a custom collator provider which returns collator with strength of SECONDARY, which gives case-insensitive comparison for EQUAL and LIKE. Copied from the blog above:- Create a class that extends java.text.spi.CollatorProvider and returns a collator that orders strings the way you want it to
  8. Proper collation support, independent of O.S is really a nice addition to postgresql. This will make easier to port from databases that have different collations. I have one Sybase ASE and one SqlServer with collation LATIN1_CI_AI (case insensitive, accent insensitive).
  9. I believe MySQL by default searches string in case insensitive manner while using '=' and 'like' operators in SELECT statement. I have changed the default collation of the MySQL server to ''latin1_general_cs" from "latin1_swedish_ci". After doing this, the string search is case sensitive for both '=' and 'like' operators.

  26. Collation performs comparisons of the base characters only, ignoring other differences such as diacritics and case. 2: Secondary level of comparison. Collation performs comparisons up to secondary differences, such as diacritics. That is, collation performs comparisons of base characters (primary differences) and diacritics (secondary differences).
  27. PostgreSQL 12: A custom nondeterministic collation can be created to change the default text comparison behavior and sort order. DB2 & PostgreSQL 11 : Do not support case-insensitive comparisons. Consider generating an extra column with text converted to uppercase and converting your query argument to uppercase as well.

  2. The standard approach to doing case-insensitive matches in PostgreSQL has been to use the lower function when comparing values, for example SELECT * FROM tab WHERE lower(col) = LOWER(?); This works reasonably well, but has a number of drawbacks:
  3. Parameter names are case-insensitive and case-preserving in this map, like in PostgreSQL itself. So DateStyle and datestyle are the same key. As of PostgreSQL 11 the reportable parameter list, and related PgJDBC interfaces or accesors, are:
  4. Locale-aware Unicode collation algorithm-based collations were introduced in DB2 9.5 fixpack 1. These collations can be tailored to ignore case and/or accents. When a database is created with a collation that ignores case, all database operations become case insensitive. It is necessary to create a new Unicode database to use these collations.
  5. Yeah. Case insensitive searches like this are pretty much the first example given for why you might want to use an expression index. The expression in an expression index has to be immutable, but upper() is - it will always give the same output for a given input.
  6. Unicode/multi-lingual support. To quote the PostgreSQL manual: CITEXT's case-folding behavior depends on the LC_CTYPE setting of your database. How it compares values is therefore determined when the database is created. It is not truly case-insensitive in the terms defined by the Unicode standard.
  7. Case-insensitive operations are sometimes said to fold case, from the idea of folding the character code table so that upper- and lowercase letters coincide. In filesystems Edit In filesystems in Unix-like systems, filenames are usually case-sensitive (there can be separate readme.txt and Readme.txt files in the same directory).
  8. Notice that, even though the collation is case-insensitive and accent-insensitive, the database engine still lists the names with an initial capital letter first for each sorted group. You’ll find that the case-insensitive collations are not consistent in how they treat the first letter.
  9. PostgreSQL breaks ties using a byte-wise comparison. Comparison that is not deterministic can make the collation be, say, case- or accent-insensitive. For that, you need to choose an appropriate LC_COLLATE setting and set the collation to not deterministic here. Nondeterministic collations are only supported with the ICU provider.
  10. Case Sensitive. In MS SQL if a database is created with Case Sensitive COLLATION then table names and column names are case sensitive otherwise, if the database is created with a Case Insensitive Collation then identifier names are case insensitive. For Example. If you created a table in Case Sensitive Collation database, like this
  11. In stringi: Character String Processing Facilities. Description Usage Arguments Details Value References See Also Examples. View source: R/compare.R. Description. These functions may be used to determine if two strings are equal, canonically equivalent (this is performed in a much more clever fashion than when testing for equality), or to check whether they are in a specific lexicographic order.

  16. Case insensitive indexes should be used when running a case insensitive "starts with" regex like this /^searchterm/i. Currently if you make a case insensitive collation and run a "starts with" regex query like this /^searchterm/i, mongodb will not use the index. This is a real problem for any application that uses an autocomplete feature.

  20. A collation is an SQL schema object that maps an SQL name to locales provided by libraries installed in the operating system. A collation definition has a provider that specifies which library supplies the locale data. One standard provider name is libc, which uses the locales provided by the operating system C library.These are the locales that most tools provided by the operating system use.
  21. Jan 31, 2008 · One of the most annoying things for people coming from a Windows environment is that PostgreSQL is case-sensitive whereas MS Access in-general is not (except when querying case sensitive databases). Explaining this to users and training them on case sensitivity is just a lot of hassle, not to mention the time-loss of having to upper case things.
