| SQL / SQLite trigger question Hey all,
I'm writing a server app and client app in C# to handle some file caching.
I have these two tables:
mycommand.CommandText = "CREATE TABLE IF NOT EXISTS 'cache' (id INTEGER PRIMARY KEY, md5 VARCHAR(32), filename char(255), timeAdded TIMESTAMP, timeLastRef TIMESTAMP, fileize INTEGER, filedata BLOB)";
mycommand.ExecuteNonQuery();
mycommand.CommandText = "CREATE TABLE IF NOT EXISTS 'info' (totalFiles INTEGER, totalFileSize INTEGER)";
mycommand.ExecuteNonQuery();
I want to update the 'info' table's totalFiles and totalFileSize whenever a DELETE or INSERT is done on 'cache'. I need to use triggers since they are an atomic operation as far as SQLite is concerned.
Does anyone know the correct syntax for something like that? I googled it and came up with very very little info that applies to my specific case.
Thanks in advance! |
