But it does <a href="omitted.html">omit some features</a>while at the same timeadding a few features of its own. This document attempts todescribe precisely what parts of the SQL language SQLite doesand does not support. A list of <a href="lang_keywords.html">keywords</a> is also provided.</p><p>In all of the syntax diagrams that follow, literal text is shown inbold blue. Non-terminal symbols are shown in italic red. Operatorsthat are part of the syntactic markup itself are shown in black roman.</p><p>This document is just an overview of the SQL syntax implementedby SQLite. Many low-level productions are omitted. For detailed informationon the language that SQLite understands, refer to the source code andthe grammar file "parse.y".</p><p>SQLite implements the follow syntax:</p><table width="100%" cellpadding="5" border="0"><tr><td valign="top"><ul><li><a href="lang_altertable.html">ALTER TABLE</a></li><li><a href="lang_analyze.html">ANALYZE</a></li><li><a href="lang_attach.html">ATTACH DATABASE</a></li><li><a href="lang_transaction.html">BEGIN TRANSACTION</a></li><li><a href="lang_comment.html">comment</a></li><li><a href="lang_transaction.html">COMMIT TRANSACTION</a></li><li><a href="lang_createindex.html">CREATE INDEX</a></li><li><a href="lang_createtable.html">CREATE TABLE</a></li><li><a href="lang_createtrigger.html">CREATE TRIGGER</a></li><li><a href="lang_createview.html">CREATE VIEW</a></li><li><a href="lang_createvtab.html">CREATE VIRTUAL TABLE</a></li><li><a href="lang_delete.html">DELETE</a></li><li><a href="lang_detach.html">DETACH DATABASE</a></li><li><a href="lang_dropindex.html">DROP INDEX</a></li><li><a href="lang_droptable.html">DROP TABLE</a></li></ul></td><td valign="top"><ul><li><a href="lang_droptrigger.html">DROP TRIGGER</a></li><li><a href="lang_dropview.html">DROP VIEW</a></li><li><a href="lang_transaction.html">END TRANSACTION</a></li><li><a href="lang_explain.html">EXPLAIN</a></li><li><a href="lang_expr.html">expression</a></li><li><a href="lang_insert.html">INSERT</a></li><li><a href="lang_conflict.html">ON CONFLICT clause</a></li><li><a href="pragma.html">PRAGMA</a></li><li><a href="lang_reindex.html">REINDEX</a></li><li><a href="lang_replace.html">REPLACE</a></li><li><a href="lang_transaction.html">ROLLBACK TRANSACTION</a></li><li><a href="lang_select.html">SELECT</a></li><li><a href="lang_update.html">UPDATE</a></li><li><a href="lang_vacuum.html">VACUUM</a></li></ul></td></tr></table><hr><small><i>This page last modified 2008/04/15 19:31:05 UTC</i></small></div></body></html>⌨️ 快捷键说明
