<p>The REINDEX command is used to delete and recreate indices from scratch.
This is useful when the definition of a collation sequence has changed, or
when there are <a href="expridx.html">indexes on expressions</a> involving a function whose definition
has changed.
</p>

<p>If the REINDEX keyword is not followed by a collation-sequence or database 
object identifier, then all indices in all attached databases are rebuilt.

</p><p>If the REINDEX keyword is followed by a collation-sequence name, then
all indices in all attached databases that use the named collation sequences
are recreated. 

</p><p>Or, if the argument attached to the REINDEX identifies a specific 
database table, then all indices attached to the database table are rebuilt. 
If it identifies a specific database index, then just that index is recreated.

</p><p>For a command of the form "REINDEX <i>name</i>", a match
against <span class='yyterm'>collation-name</span> takes precedence over a match
against <span class='yyterm'>index-name</span> or <span class='yyterm'>table-name</span>.
This ambiguity in the syntax may be avoided by always specifying a
<span class='yyterm'>schema-name</span> when reindexing a specific table or index.
