<h1 align="center">SQL As Understood By SQLite</h1><p><a href="lang.html">[Top]</a></p><h2>DROP TABLE</h2><h4><a href="syntaxdiagrams.html#drop-table-stmt">drop-table-stmt:</a></h4><blockquote> <img alt="syntax diagram drop-table-stmt" src="images/syntax/drop-table-stmt.gif"></img> </blockquote>
123
<p>The DROP TABLE statement removes a table added with the
124
<a href="lang_createtable.html">CREATE TABLE</a> statement. The name specified is the
125
table name. The dropped table is completely removed from the database
126
schema and the disk file. The table can not be recovered.
127
All indices and triggers
128
associated with the table are also deleted.</p>
130
<p>The optional IF EXISTS clause suppresses the error that would normally
131
result if the table does not exist.</p>
133
<p>If <a href="foreignkeys.html">foreign key constraints</a> are enabled, a DROP TABLE command performs an
134
implicit <a href="lang_delete.html">DELETE FROM <tbl></a> command before removing the
135
table from the database schema. Any triggers attached to the table are
136
dropped from the database schema before the implicit DELETE FROM <tbl>
137
is executed, so this cannot cause any triggers to fire. By contrast, an
138
implicit DELETE FROM <tbl> does cause any configured
139
<a href="foreignkeys.html#fk_actions">foreign key actions</a> to take place.
140
If the implicit DELETE FROM <tbl> executed
141
as part of a DROP TABLE command violates any immediate foreign key constraints,
142
an error is returned and the table is not dropped. If
143
the implicit DELETE FROM <tbl> causes any
144
deferred foreign key constraints to be violated, and the violations still
145
exist when the transaction is committed, an error is returned at the time
