def resolverExpression(resolvablesExpression: String, queryString: String, errorMessage: String): String

Returns resolver expression string - db function call to check resolver result and throw exception when result is not unique or is missing.

Returns resolver expression string - db function call to check resolver result and throw exception when result is not unique or is missing. This is important to avoid silent deletion of data from db. Default implementation is

s"checked_resolve(_, array($queryString), $errorMessage)"

For postgresql bigint and string resolvers checked_resolve db function can be defined as:

create or replace function checked_resolve(resolvable text, resolved bigint[], error_message text)
  returns bigint as $$
begin
  if array_length(resolved, 1) > 1 or resolvable is not null and resolved[1] is null then
    raise exception sqlstate '235BX' using message = error_message;
  else
    return resolved[1];
  end if;
end;
$$ language plpgsql immutable;

create or replace function checked_resolve(resolvable text, resolved text[], error_message text)
  returns text as $$
begin
  if array_length(resolved, 1) > 1 or resolvable is not null and resolved[1] is null then
    raise exception sqlstate '235BX' using message = error_message;
  else
    return resolved[1];

end;
