hello All
I tried the following commands:
ponto=# explain select * from horarios where funcionario>10000;
NOTICE: QUERY PLAN:
Seq Scan on horarios (cost=0.00..176.21 rows=2432 width=132)
EXPLAIN
ponto=# explain select * from horarios where funcionario=10000;
NOTICE: QUERY PLAN:
Index Scan using horarios_func_data on horarios (cost=0.00..55.37 rows=73
width=132)
EXPLAIN
So my question is why in the first case the postgre did'nt use the index
and made a seq scan ??
thanks and sorry about my english...
