Re: ERROR: SELECT query has no destination for result data

Sorry, try

select into numRegistros count(*) from base.emissor_ponto_venda where
id = PontoVenda_Emissor;

The thing you are selecting into needs to match what you are
selecting. So in your examples below, record is needed when you use
"* from ...". If you just need to look at one value:

select into num_em_pdv id from base.emissor_ponto_venda where id =
PontoVenda_Emissor;
