+<blockquote><pre>
+int sqlite3_deserialize(
+ sqlite3 *db, /* The database connection */
+ const char *zSchema, /* Which DB to reopen with the deserialization */
+ unsigned char *pData, /* The serialized database content */
+ sqlite3_int64 szDb, /* Number bytes in the deserialization */
+ sqlite3_int64 szBuf, /* Total size of buffer pData[] */
+ unsigned mFlags /* Zero or more SQLITE_DESERIALIZE_* flags */
+);
+</pre></blockquote>
+<p>
+The sqlite3_deserialize(D,S,P,N,M,F) interface causes the
+<a href="../c3ref/sqlite3.html">database connection</a> D to disconnect from database S and then
+reopen S as an in-memory database based on the serialization contained
+in P. The serialized database P is N bytes in size. M is the size of
+the buffer P, which might be larger than N. If M is larger than N, and
+the SQLITE_DESERIALIZE_READONLY bit is not set in F, then SQLite is
+permitted to add content to the in-memory database as long as the total
+size does not exceed M bytes.</p>
+
+<p>If the SQLITE_DESERIALIZE_FREEONCLOSE bit is set in F, then SQLite will
+invoke sqlite3_free() on the serialization buffer when the database
+connection closes. If the SQLITE_DESERIALIZE_RESIZEABLE bit is set, then
+SQLite will try to increase the buffer size using sqlite3_realloc64()
+if writes on the database cause it to grow larger than M bytes.</p>
+
+<p>The sqlite3_deserialize() interface will fail with SQLITE_BUSY if the
+database is currently in a read transaction or is involved in a backup
+operation.</p>
+
+<p>It is not possible to deserialized into the TEMP database. If the
+S argument to sqlite3_deserialize(D,S,P,N,M,F) is "temp" then the
+function returns SQLITE_ERROR.</p>
+
+<p>If sqlite3_deserialize(D,S,P,N,M,F) fails for any reason and if the
+SQLITE_DESERIALIZE_FREEONCLOSE bit is set in argument F, then
+<a href="../c3ref/free.html">sqlite3_free()</a> is invoked on argument P prior to returning.</p>
+
+<p>This interface is omitted if SQLite is compiled with the
+<a href="../compile.html#omit_deserialize">SQLITE_OMIT_DESERIALIZE</a> option.
