In the recent version, it is getting better with some of the support, but overall, PostgreSQL is not easy to deal with when there are set of codes and one has to execute them in succession. Specifically the 4D SQL function DATE_TO_CHAR. However, the SQL standard has an odd mix of date and time types and capabilities. openssl pkcs12 -export -in postgresql. Although the @DateFormat local variable is declared at the beginning of the script, there is a GO command just before the group of statements that prints the current date into the different date formats. To make a trigger in PostgreSQL we need to declare a stored function and then declare a trigger. A vendor I'm working with uses PostgreSQL and it is so strange.
