Re: [sqlite] Porting SQLite to another operating system (not supported out of the box)

this contains a very basic vfs implementation; kinda uses internal file abstraction stuff so a lot can be stripped out and replaced with fopen/fread/etc... https://code.google.com/p/c-system-abstraction-component-gui/source/browse/src/sqlite/sqlite_interface.c maybe it's more cryptic than I think

Re: [sqlite] sqlite journal file question

I don't think it can be done, and if it could be done, it would not be wise. The journal is owned and specific to a connection. a hot Journal for connection A on DB 1 cannot ever be used to roll back or affect in any way connection B on DB 2. However, when you say the "standby is syncing", I

Re: [sqlite] sqlite journal file question

I would say no. The journal file stores pages referenced by page no and when replayed will write those pages back to the main DB at the appropriate physical offset. Although the content of your DB's at a logical level may be the same, it is unlikely that they will be exact copies at a binary level

Hi All We have two systems which are running in active/standby configuration. The active machine, is actively writing sqlite transactions to a file abcd.db. The standby is syncing the abcd.db file from the active machine on a communication channel and writing the delta records to the abcd.db

I just want to inject my $.05. As for me, binding an array or table is very well aligns with a syntax of WITH clause. So example query might look like: WITH array(x) AS ?001 SELECT x FROM array Or WITH my_table(x, y, z) AS ?001 SELECT * FROM my_table T
