Query Language Understood by SQLite
SQL As Understood By SQLite SQLite understands most of the standard SQL language. But it does omit some features while at the same time adding a few features of its own. This document attempts to describe precisely what parts of the SQL language SQLite does and does not support. A list of SQL keywords is also provided.

UPDATE
An UPDATE statement is used to modify a subset of the values stored in zero or more rows of the database table identified by the qualified-table-name specified as part of the UPDATE statement. 2.
