DEFINE - Defining a named symbol


[ name ] [ value ]


This defines a named symbol. Symbol names must follow the slonik rules for constructing identifiers, by starting with a letter, followed by letters, numbers, and underscores.
Symbol values may contain spaces and may recursively contain symbol references.
Symbols are referenced by using a ‘@’ followed by the symbol name. Note that symbol referencing is suppressed inside string literals.


define    cluster movies;
define    sakai   1;
define    chen    2;
define    fqn     fully qualified name;
cluster name = @cluster; node @sakai admin conninfo = 'service=sakai-replication'; node @chen admin conninfo = 'service=chen-replication'; define setMovies id = 1; define sakaiMovies @setMovies, origin = @sakai;
create set ( @sakaiMovies, comment = 'movies' );
set add table( set @sakaiMovies, id = 1, @fqn = 'public.customers', comment = 'sakai customers' ); set add table( set @sakaiMovies, id = 2, @fqn = 'public.tapes', comment = 'sakai tapes' ); echo 'But @sakaiMovies will display as a string, and is not expanded';
