ij accepts several commands to control its use of JDBC. It recognizes
a semicolon as the end of an ij or SQL command; it treats semicolons
within SQL comments, strings, and delimited identifiers as part of those constructs,
not as the end of the command. Semicolons are required at the end of an ij or SQL statement.
All ij commands, identifiers, and keywords are case-insensitive.
Commands can span multiple lines without any special escaping for the ends
of lines. This means that if a string spans a line, the new lines will show
up in the value in the string.
ij treats any command that it does not recognize as an SQL command
to be passed to the underlying connection, so syntactic errors in ij commands will cause them to be handed to the SQL engine and will probably
result in SQL parsing errors.
