You create table t2 with plain vanilla integer field, then create insert and 
delete triggers on t1 that update t2.

[sqlite] one column is another table's row num

2010-03-17 Thread liubin liu

I want to create two tables like:
create table t1 (id INT PRIMARY KEY, cont TEXT);
create table t2 ({select count(*) from t1} INT);

How could I do it?
