Sqlite> create virtual table "a b c" using fts2 (t) įTS2 sql: CREATE TABLE main.a b c_content(c0t) A quick fix would be to make the azColumn storage be lowercase, but the core problem is that field names probably shouldn't be run through the tokenizer in the first place.Īll table names should be quoted in the FTS module code. It doesn't work because fts is keeping the column name as 'B', but the query parsing uses the results from the tokenizer, which are case-folded, and 'b' != 'B'. SELECT rowid FROM t WHERE t MATCH 'B:test' - no results SELECT rowid FROM t WHERE t MATCH 'b:test' - no results SELECT rowid FROM t WHERE b MATCH 'test' - works SELECT rowid FROM t WHERE t MATCH 'test' - works Unfortunately, fts cannot do field-level queries: INSERT INTO T (a, B) VALUES ('Second', 'Test') INSERT INTO t (A, b) VALUES ('Test', 'Columns') At the SQL level, things are case-insensitive: "Workaround" is to compile with -DNDEBUG=1, but the person who reported this to me was using the fts2 dll from .įts field-based queries are not correctly case-insensitive. sqlite/ext/fts3/fts3.c:478: dataBufferAppend: Assertion `nSource>0 & pSource!=((void *)0)' failed. Select a from test where test match ('a:gamma* OR a:delta*') The fix will submot a modified configure file with a latest version of libtool. This is the auto-config problem occured at cross-compile SQLite to xscale or arm target with certain tool-chain. The default setting will keep sam.eĬonfigure file and libtool doesnot work for cross compiling so sqlite autoconfg should allow build to generate libsqlite-2.8.6.so instead of libsqlite.so.0.0.0 as an option.
libtool do have an option "-release VERSION". so binary file and ship it with your product, you may want a stand-alone worked binary file. When you compile the sqlite by using the autoconf tools, it only produce the version control binary: libsqlite.so libsqlite.so.0 and libsqlite.so.0.0.0, and it will not work if you just want to using libsqlite.so alone. Adding releasemode option to allow libtool link release
