Re: [MonetDB-users] Combined table is not really combined after all

Tried the whole process. Still the same problem (table_combined has the same scheme as table_1): insert into table_combined select * from table_1; insert into table_combined select * from table_2; select count(*) from table_combined; this gives ONLY the number of records in table_1, but table_combined as roughly same size as the other two combined. NONE OF THE TABLE HAS ANY INDEXING Could someone please confirm if this is a bug? Both table_1 and table_2 has over 200million rows of data. On Sat, Mar 21, 2009 at 4:47 PM, Yue Sheng wrote:

(1) There's no index or key or anything on the table.(2) The combined table is the size of table_1 + table_2. But only table_1 shows up in query

Hi Yue,

is there any chance that you have set uniqueness in the table specs and thus not inserting duplicate tuples from table_1 and table_2? If not, then I would guess that this is a bug and it needs further investigation.

two tables: table_1 and table_2 both have exactly the same schema.

has 2.15MM rows of data, table_2 has 3.35MM row of data. No indexing created a new table: table_combined using same schema as table_1 insert into table_combined select * from table_1; (30 minutes later) insert into table_combined select * from table_2;

(40 minutes later) select count(*) * 1 from table_combined; this give ONLY 2.15MM rows with same rows as table_1 What happened to table_2?!? Yes, I've check dfarm size. It equals 2*(table_1 + table_2 ) So it's there but "just not seeing it"
