Hi All,

Using PostgreSQL v9.3 on Linux Red Hat...

I've got a script that I'm running from the Linux command prompt that I need to pass 2 parameter's into the psql script without using the VI Editor.  Is there an easy way to accomplish this?

psql <database> -f <scriptname> -l <log_file>



Thank you in advance.
Denise

It really depends on how you want to use the variables in the script.

psql has a '-v' option which you can use to set variables that can be
used with the ':varname' syntax inside of the script, for example:

psql -v table=abc -f script.sql

Inside of script.sql you can then have ':table', like so:

select * from :table;

and that ':table' will be replaced by 'abc' when psql is run with the
'-v table=abc' parameter.

Hope that helps!

Thanks!

Stephen

What's wrong with doing it like this, for example?

#!/bin/bash
user=$1
database=$2
table=$3
myfield=$4
logfile=$5
mysql="select $4 from $3;"
psql -U $user $database -c "mysql" -l "$5"




Then:
/tmp/myscript postgres mydb mytable myfield /tmp/mylog

See the psql command line variable options (-v, --set, --variable).
