Re: [sqlite] Accessing sqlite3 through javascript.
I would like to thank you all first for replying to my query.. You have cleared my doubt to a great extent.However I still have somethings to be cleared.I will ask them later after studying sqlite a bit more. Its better to ask precise questions rather than vauge queries. Thank you. --- On Sat, 16/5/09, P Kishor punk.k...@gmail.com wrote: From: P Kishor punk.k...@gmail.com Subject: Re: [sqlite] Accessing sqlite3 through javascript.

One would have to use some kind of server-side js and then interact with that via the client-side js.

[sqlite] append table
howdy! Questions: suppose tables t1 t2 exits in two separate db files, d1 d2 respectively. t1 t2 have identical schemas, but different data. I want to append t2 to t1. I suppose the way to do that is to open a connect to d1, use the attach command to reference d2.t2 and issue a INSERT INTO t1 SELECT * FROM d2.t2; query. Is that correct? Is there a better way? Is this operation inefficient or pitfalls any pitfalls to watch out for? -James ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

[sqlite] Updating two tables rows in one sql statement
Hello, I'm trying to update two tables with one statement but, i'm not getting something right. can someone here help me , or guide me to the right place to get help?

The relationship between ingredients and recipes is many-to-many; consider having a THIRD table which tells what quantity of ingredient I (if any) is used in recipe R.
