Yes, it's much faster - but still much too time-consuming to make it default (more than 10 additional seconds on ~300 MB database file). > Note that "PRAGMA quick_check" is currently an undocumented experimental > feature. It has been present for almost a year though.

You could use "PRAGMA quick_check", which is similar to integrity_check but runs more quickly. Note that "PRAGMA quick_check" is currently an undocumented experimental feature.

[sqlite] Faster (can be shallow) "integrity_check"?
I would to make automatic test of the database integrity each time before accessing, just to avoid the problems with broken files, which are resulting in error message: "database disk image is malformed". Unfortunately, "PRAGMA integrity_check" takes very long time. Does there exist any possibility to make a much shorter test, for just very obvious cases, like incomplete database file (when f.e. there has been taken just part of the database file during downloading)? -- pozdrawiam / regards Zbigniew Baniewski ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
