How can I use datetrunc in plpgsql function with quote 'day'?
e.g.
str_QuerySql = ''SELECT 1 FROM ot_Source WHERE source_code = ''
|| quote_literal(str_Source ) ||
'' and status = ''
|| quote_literal(str_ACT) ||
'' and (current_date - date_trunc('day', effective_date) ) >= 0 '' ||;
open cursor_source FOR EXECUTE str_QuerySql;
FETCH cursor_source INTO int_RtnVal;
I got error on date_trunc('day', effective_date) because the 'day'. How can I quote
it? I have tried quote_literal() function like this:
str_day = ''day''
'' and (current_date - date_trunc('' || quote(str_day) || '', effective_date) ) >= 0 '' ||;
but show "attribute day not found"
Please help.
