Hai Meng, Can you please provide the schema of uniquecatalog11 and uzone? Does the crash also happen if these two tables are empty? Otherwise, we’ll need some data to reproduce the crash as well. Thanks, Jennie

Hi Meng, how did you define unique_seq? It does not seem to exist by default ... A segfault is always a bug. Please file a bug report. Why do you declare uzone in the functions? Wouldn't these do exactly the same, but simple? create function neighbor19() returns table (ra_avg double) begin return table( select ra_avg from uniquecatalog11 as u0 where id between 10 and 20 ); end; create function neighbor20() returns table (ra_avg double) begin return table( select ra_avg from uniquecatalog11 as u0 where ra_avg between 10 and 20 ); end; create function neighbor30() returns table (ra_avg double) begin return table( select ra_avg from uniquecatalog11 as u0 where id between 10 and 20 and ra_avg between 10 and 20 ); end; Best, Stefan ----- On Jul 19, 2015, at 9:13 PM, integrity 357416268@qq.com wrote:

Hi Stefan, This is a simplified version of my real function, I make it simpler and stupid to locate problem, the actual one is: CREATE FUNCTION neighbor(ra double, decl double, radius double) RETURNS TABLE (uniqueid BIGINT) BEGIN DECLARE TABLE uzone (id bigint, ra_avg double, decl_avg double, zone smallint, x double, y double, z double); DECLARE ozone double; DECLARE zoneheig double; DECLARE ox double; DECLARE oy double; DECLARE oz double; SET zoneheig=1e1/3600; SET ozone=decl/zoneheig; SET ox=COS(RADIANS(decl)) * COS(RADIANS(ra)); SET oy=COS(RADIANS(decl)) * SIN(RADIANS(ra)); SET oz=SIN(RADIANS(decl)); INSERT INTO uzone select id,ra_avg,decl_avg,zone,x,y,z from uniquecatalog11 order by zone; RETURN TABLE( SELECT id AS uniqueid FROM uzone u0 WHERE u0.zone BETWEEN ozone-1 AND ozone+1 AND u0.ra_avg between ra-alpha(decl, radius) and ra+alpha(decl, radius) AND u0.decl_avg between decl-radius and decl+radius AND u0.x*ox+u0.y*oy+u0.z*oz > cos(radians(radius)) ) ; END; I need uzone to make the uniquecatalog11 table order by zone. I can remove the order by and don't declare temporary table, but for larger amounts of row counts in future, sorting will help, so I keep it. On my side, it exits every time for now. If I use existing table rather than temporary table, the above function definition will be successful! It exits only when using temporary table and combination of conditions.
