Dear Mr. Simon Slavin: I have implemented the lectura of a csv file in my program as "import". I have followed yours instructions (the last one and others previous) . Thanks for your instructions. The program works fine with csv files of one or two rows, but when I try to read a file with 9

[sqlite] Multiple sessions, page sizes and cache

Hi all, We have an application with multiple databases of different page sizes. We keep a few long-running sessions, but also open transient sessions occasionally. In an effort to reduce memory usage/fragmentation, we're trying to configure SQLite to allocate as much memory as necessary up-front

[sqlite] does integrity check ever modify the db file?

Hey all, can 'pragma integrity_check' ever modify the file? For instance in case of a journal file laying around (which was journal file of the same schema db but a bit different data)? The following is what I think happened: a.db and b.db are two sqlite dbs of size ~5mb which have same schema

Re: [sqlite] Null returned from NOT NULL column thanks to undetected corruption

My view is that the general thinking of the program here is simply: "just don't make things worse." It can't help what pragmas (ie ignore_check_constraints, writable_schema etc) others may have turned on for their connections, or what sort of junk was there when it arrived. In its head it's

[sqlite] Exiting SQLite3 from within a (.bat) file

Hello,I have a batch (.bat) file that runs a C program to pre-process a text file to a clean .csv file.  Then the batch file runs SQLite3 -init to execute dot (.) commands.  Everything works great except the last dot command ".exit" or ".quit" to close the SQLite3 program out.  I always have to
