The UNIX redirection symbols, “ <” and “>”, provide a similar mechanism to the
-i and -o options.
For example:
isql -Usa < input > output
You can direct
isql to take input from the terminal, as shown in this
example:
isql -Usa -Ppassword -Sserver_name << EOF > output use pubs2
go
select * from table
go
EOF
“
<<EOF” instructs
isql to take input from the
terminal up to the string “
EOF.” You can replace “
EOF”
with any character string. Similarly, the following example signals the end of input with
Ctrl-d:
isql -Usa << > output
