GrainGenes SQL Interface

This page allows you to perform raw SQL queries directly. This is the ultimate power query. We don't know of any other Web-accessible databases that open this privilege to their users. It entails some risk but we're confident that it's minimal because we know our users are responsible. But, we hope, not timid. We want this interface to be used. Please click here for full information on how to use it.

Premade Queries:
SQL query:	-- Loci near a specified locus, on any map select distinct locus_1.name as Query, map.name as Map, locus_2.name as Locus, p2.begin as Position, ROUND(ABS(p2.begin-p1.begin),1) as Distance from locus locus_1 inner join maplocus p1 on locus_1.id = p1.locusid and p1.begin is not null and locus_1.name like 'wmc283' inner join map on p1.mapid = map.id -- Include only those maps that use cM units. inner join mapdataremark on map.mapdataid = mapdataremark.mapdataid and mapdataremark.type = 'Map_units' and mapdataremark.remark like '%cM%' -- First get the nearby loci on this map: left join maplocus p2 on p1.mapid = p2.mapid and ( ABS(p2.begin - p1.begin) < 10 ) -- Then get the names of these nearby loci: left join locus locus_2 on p2.locusid = locus_2.id where -- Don't list locus_1 if there are no neighbors: locus_2.name is not null order by locus_1.name, map.name, p2.begin
