Statement Object Interface Statement object is a dynamically allocated object, created by the statement method of a database object command. The object provides the following methods. The methods are called as commands after the statement object identifier. Command run executes the statement and returns the whole result set immediately. The command may be followed with the list of sql arguments, if the statement expects them.
Empty argument is interpreted as null value.
Notice that the arguments are given as a list of arguments. Safest way to create argument lists is through the tcl list command. This is the default command. It should be used when it is possible that given argument value may be one of the other command keywords. Method execute executes the given statement, but does not return the result set.
