[sqlite] CREATE INDEX
If I call CREATE INDEX on an existing table will the index be automatically updated if the table is altered or do i have to create the index again, will this occur between runs? I also notice that CREATE INDEX optionally takes a UNIQUE keyword. If I create a table from scratch how do I define the column so that it is an index but not UNIQUE.

[sqlite] error from sqlite3_get_table
I get and SQLITE_ERROR code form sqlite3_get_table. Upon checking sqlite3_errcode and sqlite3_errmsg I get 0 and 'not an error'. The command SELECT * FROM `alarm_history` ORDER BY `alarm_id`; is very simple and most of the time it workswhy am I getting an error occasionally?

Are there any docs on how to make the amalgamation. I have to make this executable smaller... 409K is too big. Gregor On 23-Jun-08, at 1:01 PM , Jay A.

[sqlite] -DSQLITE_OMIT_TRIGGER
Hi, I'm trying to compile the amalgamated src in 3.4.8 with - DSQLITE_OMIT_TRIGGER and I get the following errors: Undefined symbols: "_sqlite3TriggerSelectStep", referenced from: _sqlite3Parser in sqlite3.o "_sqlite3TriggerUpdateStep", referenced from: _sqlite3Parser in sqlite3.o "_sqlite3BeginTrigger", referenced from: _sqlite3Parser in sqlite3.o "_sqlite3FinishTrigger", referenced from: _sqlite3Parser in sqlite3.o "_sqlite3DropTrigger", referenced from: _sqlite3Parser in sqlite3.o "_sqlite3TriggerInsertStep", referenced from: _sqlite3Parser in sqlite3.o _sqlite3Parser in sqlite3.o "_sqlite3TriggerDeleteStep", referenced from: _sqlite3Parser in sqlite3.o "_sqlite3DeleteTriggerStep", referenced from: _yy_destructor in sqlite3.o ld: symbol(s) not found I get errors like this with a number of the OMIT defines. I am trying to make my executable smaller by removing stuff I do not use.

Re: [sqlite] SQL question
I did change it to: UPDATE `table` SET `id` = `id` + 32768 WHERE `id` >= x and then I decrement everything over 32768 by 32767 to get it back in line. This was required because a single update on a primary key did return an error about a key conflict when only incrementing by 1!

Re: [sqlite] SQL question
Hi, thanks this is great. Of course I forgot to mention that the id is a primary key, so I get an error about duplicate primary keys. I tried this: update binary_report_fmt set column_id = column_id + 1 where column_id = (select column_id from binary_report_fmt where column_id >= 3 order by column_id desc); but it only updates the last item. I guess I can make it a non- primary key..then it works perfectly.

[sqlite] SQL question
Sorry about this, but this is a SQL question and not a SQLite specific question. Is there a way to increment a value in a table in-situ. Without reading it, incrementing it, writing it? I need to insert an entry into a table, it has an id, all entries with id's >= the id need to be incremented to keep the id's unique ie 1 bob 2 joe 3 irene someone wants to insert 2 sarah, I need the table to look like this 1 bob 2 sarah 3 joe 4 irene Any help would be great. thanks - Gregor ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
[sqlite] quick transaction question
When doing transactional commits I do int error = sqlite3_Exec( .., "BEGIN TRANSACTION;", ... ) // can this ever return an error? int error = sqlite3_exect( ..., "some update command", ... ) if I get an error code, must I never do the "COMMIT;". what if I do?
