What would be the syntax for putting a single row from a cursor into a
variable? I have tried:
FETCH INTO left left_cursor;
which says syntax error, and
left = FETCH left_cursor;
which gives the error 'ERROR: missing datatype declaration at or near "="'
Have to declare Left variable as record data type declaration part of the
function
It is.
CREATE OR REPLACE FUNCTION overlap_gene_primer() RETURNS SETOF RECORD AS $$
DECLARE
left location;
retval RECORD;
BEGIN
DECLARE left_cursor NO SCROLL CURSOR FOR SELECT location FROM location,
gene WHERE location.id = gene.id ORDER BY objectid, start, end;
left = FETCH left_cursor;
END;
$$ LANGUAGE plpgsql;
