Some options such as

\fB\-\-create\fR

\fB\-\-query\fR

enable you to specify a string containing an SQL statement or a file containing statements\&. If you specify a file, by default it must contain one statement per line\&. (That is, the implicit statement delimiter is the newline character\&.) Use the
|

\fB\-\-delimiter\fR

option to specify a different delimiter, which enables you to specify statements that span multiple lines or place multiple statements on a single line\&. You cannot include comments in a file;
