Please execute the following in SQL Database Browser and in your iPad app: SELECT sqlite_version() It's okay that the results from the two pieces of software are different, but knowing what they are might help us figure out what's going on. Please also copy the database to your computer, and use the SQLite shell tool to execute the same query. The shell tool is as close to canonical as anything is: whatever result that gets is the 'right' result. Could you possibly reduce your database to just a few records -- just enough that it correctly reproduces your problem ? You can use the SQLite shell tool to .dump the database which will let you post a complete copy for our testing.

Re: [sqlite] Query runs in SQLite Database Browser but not in iPad app
Hi Rolf, There's nothing inherently different about SQLite execution in Objective-C or on iPad. Please post a full (though brief) sample schema, including data, that demonstrates the issue, so we can test.

[sqlite] Query runs in SQLite Database Browser but not in iPad app
I have this select statement which returns the correct results (count = 2) when run in SQL Database Browser, but not in my Objective-c iPad app (count = 0). select count(orderdata.order_id) from orderdata, custdata, orderinfo where custdata.customer_id = orderinfo.cust_id and orderdata.order_id = orderinfo.cust_id and custdata.Bus_name = 'Albertsons' I have also tried it this way using JOINs, but get the same results… select count(orderdata.order_id) from orderdata join custdata on custdata.customer_id = orderinfo.cust_id " join orderinfo on orderdata.order_id = orderinfo.order_id " where custdata.Bus_name = 'Albertsons' Any ideas why? ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
Re: [sqlite] [PATCH] add malloc and alloc_size attributes to allocation functions
The list strips attachments... you might try sqlite-dev?

The malloc attribute specifies that a function behaves like malloc (i.e., it returns a fresh pointer to an allocated block). It's mainly used for optimization purposes.

Clang will also take advantage of this when instrumenting code for run-time buffer overflow detection.

[sqlite] tclsqlite.c: MD5Final() typo
Hi, I think there's a small typo in the MD5Final() function in tclsqlite.c. line 3388 says: memset(ctx, 0, sizeof(ctx));/* In case it is sensitive */ I think you wanted to write sizeof(*ctx) there instead. (I'm looking at sqlite 3.7.12.1 sources) Nuno ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
