Oracle stores it internally in a very specific arrangement of bytes and you need to still interpret it in your software. Not so. OCI has native support for Number client side via OCINumber and associated functions to convert to native C types, and can do 128-bit integer arithmetic for example even when the C/C++ native types cannot. And it's a value type, not an opaque type, so you can decode the internal well-known byte rep if you want to even. --DD ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

Hi Sorry for resurrecting an old thread. I got the where clause working for queries with byte array arguments based on this discussion. I cannot find the way to use byte arrays in where clauses for update and delete statements. I know it is terrible to use byte arrays as query arguments, I need this because of some 3rd party library problems. I also know that I can query for the row and do the update using some other column in the where clause I just find that hacky. So if there is a way to do this trick for deletes and updates please let me know.

Re: [sqlite] sqlite Issue
If you're using SQLite3.exe (or equivalent CLI - Command Line Interface) then by default the database id written to memory, not to the disk. Doing something like [ sqlite3.exe test.db3] will create a test.db3 file once you do an actual transaction like creating a table. I THINK even doing a select will make the file as well. If you're writing code in some language, as Simon suggested, ensure that you're not writing to [ :memory: ] or to a directory that the app has create and write permissions.
