| Description: | ||||
|
If the only row in an FTS table is updated and the rowid/docid value is not changed, then the FTS index may become corrupt.
For example:
$ ./sqlite3 x
SQLite version 3.7.9 2011-10-13 16:36:29
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> CREATE VIRTUAL TABLE t USING fts3;
sqlite> INSERT INTO t VALUES('xxx');
sqlite> .quit
Then:
$ ./sqlite3 x SQLite version 3.7.9 2011-10-13 16:36:29 Enter ".help" for instructions Enter SQL statements terminated with a ";" sqlite> UPDATE t SET content = 'yyy'; sqlite> SELECT * FROM t WHERE t MATCH 'yyy'; Error: database disk image is malformed dan added on 2011-10-13 17:33:07: dan added on 2011-10-13 17:34:50: | ||||
