Hello list,
I need to track down the missing check numbers in a serie, table
contains a column for check numbers and series like this:
dbalm=# select doc_numero,doc_ckseriesfk from bdocs where doc_cta=1
dbalm-# and doc_tipo='CHE' order by doc_numero;
doc_numero | doc_ckseriesfk
------------+----------------
19200 | 856938
19201 | 856938
19215 | 856938
19216 | 856938
19219 | 856938
Missing numbers are:
from 19202 to 19214 and 19217,19218
Does anyone knows a way to get that done in SQL or plpgsql, thanks in
advance
