Hello,
We found and use for ESQL/C the debug feature:
ECPGdebug(int on, FILE *stream);
with very good results. Is there something similar for the psql
interpreter to debug the query of complex SQL statements like this
monster here:
SELECT ha.hnr, count(*) FROM acq_haushalt ha, acq_booking bo WHERE
ha.hjahr = 2000 AND ha.brgroup
WHERE bu.bnr = bo.bnr AND bu.band = bo.band AND bu.exemplar = ( SELECT
min(bo2.exemplar) FROM acq_booking b
WHERE bo2.hnr = bo .hnr
AND bo2.bnr = bo.bnr AND bo2.band = bo.band)
AND bu.statusrech IN (0,1) )
GROUP BY ha.hnr;
The -L logfilename flag of psql is not sufficient enough. It logs only
the query and the final result.
