The XDB Server receives and processes SQL commands as continuous, nondelimited strings. Comments can be included anywhere in an SQL command, provided they are bracketed by the characters /* and */. The XDB Server ignores all characters enclosed between these special characters. For example, the following command statement has the comment string "info on parts & suppliers" attached:
SELECT *
FROM partsupp /* info on parts & suppliers */
An alternative means of entering comments is provided in SQLWizard, where users may place comments at the end of a statement line, separating them from the statement text by a double hyphen (--). Anything on the line after the double hyphen is ignored by the system.
