# collate3.5.* - Collation factory.

#
# These tests ensure that when a user executes a statement with an

<h4>7.1 Assigning Collation Sequences from SQL</h4>

Each column of each table has a default collation type. If a collation type
other than BINARY is required, a COLLATE clause is specified as part of the

Whenever two text values are compared by SQLite, a collation sequence is
used to determine the results of the comparison according to the following
rules. Sections 3 and 5 of this document describe the circumstances under
which such a comparison takes place.
