here are the details:
CREATE TABLE DATA (
STOCK VARCHAR(55),
SYMBOL VARCHAR(8),
DATA DATE,
OPN FLOAT,
HIGH FLOAT,
LOW FLOAT,
CLS FLOAT,
VOL FLOAT);
/* Indices */
CREATE INDEX DATA_1DX1
ON DATA(STOCK);
CREATE INDEX DATA_IDX2
ON DATA(SYMBOL);
CREATE INDEX DATA_IDX3
ON DATA(DATA);
Total records: 800,000 rows, 8 fields.
exact query: SELECT STOCK FROM DATA GROUP BY STOCK ORDER BY STOCK
pc spec: p4 2.4, 512 mb
I appreciate the help. Thanks.
