Some ij commands require identifiers. These ij identifiers are case-insensitive. They must begin with a letter in the range A-Z, and can consist of any number of letters in the range A-Z, digits in the range 0-9, and underscore (_) characters.

These identifiers exist within the scope of ij only and are distinct from any identifiers used in SQL commands, except in the case of the Get Cursor command. The Get Cursor command specifies a cursor name to use in creating a result set.

ij does not recognize or permit delimited identifiers in ij commands. They can be used in SQL commands.
