Sqlite collate nocase

Additionaly, in SQLite , you can indicate that a column should be case insensitive when you create the table by specifying collate nocase in the . A COLLATE operator has the same affinity as its left-hand side operand. SQLite has three built-in collating functions: BINARY, NOCASE , and RTRIM. BINARY - Compares string data using memcmp(), regardless of text encoding. NOCASE - It is almost same as binary, except the upper case characters of ASCII are folded to their lower case equivalents before the comparison is performed.

SQL Server has support of COLLATIONS. So you can choose (and usually do) a collation with case-insensitive comparing (with “_CI” suffix). TEXT COLLATE NOCASE NOT NULL C. I might add that using sqlite3. I tried adding COLLATE NOCASE - and had some success.

In SQLite you can retrieve rows from a table in either ascending or. It turns out SQLite provides a collating function called NOCASE for this . SQLite does case-sensitive searching unless you specify COLLATE NOCASE when creating the database schema, or include COLLATE . Apparently NOCASE_UTFis custom collation for PDO driver, but it is invalid in sqlite3. Simple replacing NOCASE_UTFwith NOCASE on.

SQLite also offers an alternate collation called nocase , which treats upper- and . Since these queries are often run on the main thread for easy integration with the SQLite also provides a NOCASE index collation that is case.
