mysql -ugenome -hgenome-mysql.cse.ucsc.edu mm9 -A I start mysql with the above command. Then I want to select the rows from the result of the following query, provided that for any rows that have the same symbol, chrom and strand should be the same (basically, discard the rows that have the same symbols but different chrom and strand). Could anybody show me how to do it?
select geneName as symbol, name as refSeq, chrom, strand, txStart from refFlat group by refSeq having count(*)=1; I think that something like SELECT name FROM (SELECT name, type_id FROM (SELECT * FROM foods)); works for sqlite3 (in terms of syntax). But the following do not work for mysql. Is this a difference between mysql and sqlite3? (I'm always confused by the difference between different variants of SQL) select * from (select geneName as symbol, name as refSeq, chrom, strand, txStart from refFlat group by refSeq having count(*)=1); -- Regards, Peng -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql?unsub=arch...@jab.org
