The format `$1` is the Postgres format for parameters and cannot be used in
the cypher query. Parameters in the cypher query must take the format
`$parameter_name`. When you want to pass parameters to a cypher query, you must
add a third argument to the cypher query. This argument must be a Postgres
parameter. So your query must look like:
`SELECT * FROM cypher('testgraph', $$CREATE (v:Person {name: $var_name})$$,
$1) as (a agtype);`
When executing the query the value passed to `$1` must be an agtype map,
where the key is the variable name. NOTE: All parameters in the cypher query
are passed in the map.
Also, both AGE parameters and Postgres parameters can only be used in
prepared statements. So the above query will not currently work as it is
related to the github issues: https://github.com/apache/incubator-age/issues/39
& https://github.com/apache/incubator-age/issues/28. We are currently working
on a fix for these issues.
