[sqlite] Update in SQLite
Hi, I would like to test the SQLite in some linux embedded system. I read the limitation document and it says "To change a table you have to delete it (saving its contents to a temporary table) and recreate it from scratch." (Stated in http://www.hwaci.com/sw/sqlite/omitted.html) Does it mean when I use the "UPDATE ..." SQL statement, the table will actually be deleted and recreated by SQLite automatically? Thanks! Regards, Cai Yuan

No, the docs are talking about altering the definition of a table, not updating a row. Dave Cook

It works on the 'data' stored in the table, not the table structure itself. Scott -- POPFile, the OpenSource EMail Classifier http://popfile.sourceforge.net/ Linux 2.6.5-7.104-default x86_64
