Each Loader command comprises one or more keywords, arguments, and options.
The syntax used for Loader commands is the Backus Naur Form (BNF) with the following conventions:
<Rule name> ::= <Rule section>
The terms in angle brackets represent syntactical units. Each rule name must be resolved by a rule section.
A rule section is any combination of rules and end symbols. End symbols are numbers, literals, or keywords and are not resolved further.
Rule sections set in angle brackets indicate an optional user input.
The keywords used in the commands are written in uppercase for the sake of clarity. They can be specified by the user in upper or lower-case letters.
Blank characters are allowed in commands. These are not interpreted by the Loader.
End symbols that start with val stand for values that must be specified by the user. Remember that values for 'valLITERAL' (as specified in the syntax rules) must be placed in single quotation marks.
If you use keywords as names of columns, tables, or database users, you must place them in double quotation marks.
