----------------------------------------
Hi Sylvain,
I'm still in the process of reading the code and doc. I'll try to come up with
a POC for "Having a way to propagate values from the calling context to an ij
script. Using positional parameters $1, $2, etc." , the use case you mentioned
first.
Thanks,
Denis

> It would be nice to be able to parameterize ij scripts. At a high level, this
> would be akin to the $N parameters which you pass on the command line to Unix
> shell scripts. I think it would be easiest to understand if parameter
> substitution happened before the script was handed to the ij parser.
> It would be nice to write something like the following:
> connect 'jdbc:derby:$1;user=$2;password=$3';
> insert into $4( a ) values ( $5 );
> or something like this:
> connect 'jdbc:derby:${dbname};user=${user};password=${password}';
> insert into ${tableName} values ( ${intValue} );
