I need to make a query that involves 2 tables (the classic master-detail), I need all the records on the master table that match the where clausa but just the first record of the detail table, how can this be done with Firebird?

Thanks in advance

$result=ibase_query($conn,”SELECT FIRST 10 SKIP 20 soid,itemno,quantity,unitprice,itemovdesc,itemreserved1,itemreserved2,itemreserved3 from SODET”);

it’s not work
Warning: ibase_query() [function.ibase-query]: Dynamic SQL Error SQL error code = -104 Token unknown – line 1, char 13 10 in C:\AppServ\www\phpfirebird\sodet.php on line 12

how fixed?

Thanks for the perfect hint!
By the way, if you check this on a relativly big table (100k records), using indexes for your query, the result is confusing. While the query without ROWS or FIRST-SKIP runs in milliseconds (using the indexes), the query with the ROWS or FIRST-SKIP doesn’t use the indexes and takes 1-2 seconds to retrieve the result. It’s a bit annoying. Any comments?

Thanks Scott, it was indeed an useful tip.

I agree with you regarding Firebird documentation: it’s really really incomplete.
The community should realize how important is to have up2date docs: indeed is a major key to success.

In FirebirdSQL 2 also:

SELECT column1, column2, column3 FROM foo ROWS 10 TO 20

You are absolutely right. Guess how long I have not been using PostgreSQL…

Actually the PostgreSQL equivalent is:

SELECT column1, column2, column3 FROM foo LIMIT 10 OFFSET 20;

as you could see from here – http://www.postgresql.org/docs/8.1/static/sql-select.html#SQL-LIMIT .
