[sqlite] sqlite compound keys
If I have a table: create table tmp ( x integer, y integer ) And a an index with compound key: create unique index idx on tmp (x, y); And I did a query: select * from tmp where x = 9 Would sqlite know how to use the index to find records where x = 9? Or would it opt for a scan instead? ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
Re: [sqlite] Possible bug when rebuilding amalgamation without triggers or altertable
In response to Stepheen Beal's previous comments I do understand that not all combinations of -DSQLITE_OMIT statements will work, and past experience has shown its usually because the dependencies between the various options are not clear in the documentation. However someone has invested the effort to write the -DSQLITE_OMIT_ALTERTABLE and -DSQLITE_OMIT_FOREIGN_KEY functionality, and the person who did that may be concerned that these features do not work in current builds of SQLite, or they may have a fix which isn't part of the source distribution yet, or they may know other dependencies that need to be resolved. Those are the people I am attempting to reach via this list. If that isn't you or your not interested in a solution, then I would ask that you please don't discourage others from responding.

[sqlite] [solution] - Re: Possible bug when rebuilding amalgamation without triggers or altertable
I looked into the problem more tonight and found all of the references to the omitted functions were from the auto-generated parser. I looked at the parser source and it was checking for omits in all the right places so the functions should have have been referenced. I checked the Makefile and found that OPT_FEATURE_FLAGS still had the default settings. I manually changed OPT_FEATURE_FLAGS in the Makefile and rebuilt sqlite3.c - this time I was able to use all of the omit features and create a usable binary. So root cause of my delima seems to be that OPT_FEATURE_FLAGS isn't populated by passing in to configure as my notes had indicated, but by manually editing the Makefile and adding the desired flags to OPT_FEATURE_FLAGS.
