To view the values of these parameters, you can run the following SQL statements:
-
MySQL:
-- Show the value of a particular parameter mysql$SHOW VARIABLES LIKE '%parameter_name%'; -- Show the values of all parameters mysql$SHOW VARIABLES; -
PostgreSQL:
-- Show the value of a particular parameter postgresql=> SHOWparameter_name; -- Show the values of all parameters postgresql=> SHOW ALL;
