Hi,
Its good but can u guide me ,how to compare the values of foreign key with primary key.
Ex:
Am doing an app and have struck at a point based on sqlite database.
At first I have to create two tables on same view.In that tables I have to insert values from sqlite database tables.
In first table i have to get the values from first table.And in second table i have to get the values from second table by comparing with the foreign key.

table1 table2

id name id id2 name1
1 Mohammed 1 1 ABC

2 Rafiq 2 1 DEF

3 2 ghi

in first table i need values Mohammed,Rafiq.
And when i click on Mohammed i used to get ABC,DEF in second table or if select Rafiq then ghi must display.
I am sending an app see tht and remodule it searching from a week.
and the selected data must be displayed in text fields.
I havent sen any answer for this.If needed I have called values from database to uitable views but not able to compare and diffrentiate .I can post if any one needed.
if any one gets this post to smrafiqsmd@gmail.com
Thank u

Thomas,

It’s been so long since I wrote this post that I couldn’t tell you. I am sure I found them by searching the requisite terms on Google, however.

Hey, I just found this post while browsing a bit. It’s was very informative. I’m an iPhone app developer myself, but I’ve never used phpMyAdmin before. You said there were other tutorials out there that had a more code oriented style, would you mind pointing me to any of them?

Nice info.

Also: CONSTRAINTs / FOREIGN KEYs can be added to the Table creation as seen here, resetting INDICE counts for primary keys won’t work (e.g. “ALTER TABLE “” ALTER COLUMN “id” RESTART WITH 101;”), cration of CACHED tables won’t work and of course non-supported types have to be replaced. For BOOLEAN type one might choose INTEGER while replacing INSERT-values of FALSE with 0 and 1 resp. for TRUE.. etc.

Cheers and thanks for the heads up!
Recoding UTF-8 source can be done with native2ascii e.g. “native2ascii -revert infile outfile” for replacing \u…-encoded utf-8 with the native utf-8 encoding w/i sqlite. Or use iconv (“man iconv”) for other cases.
