Overview
Instance Attribute Summary collapse
-
#allow_literals ⇒ true, false
When false, the query string must not contain any literals and instead must bind all values.
-
#named_bindings ⇒ Hash{String => Google::Datastore::V1::GqlQueryParameter}
For each non-reserved named binding site in the query string, there must be a named parameter with that name, but not necessarily the inverse.
-
#positional_bindings ⇒ Array<Google::Datastore::V1::GqlQueryParameter>
Numbered binding site @1 references the first numbered parameter, effectively using 1-based indexing, rather than the usual 0.
-
#query_string ⇒ String
A string of the format described here[https://cloud.google.com/datastore/docs/apis/gql/gql_reference].

#named_bindings ⇒ Hash{String => Google::Datastore::V1::GqlQueryParameter}
Returns For each non-reserved named binding site in the query string, there must be a named parameter with that name, but not necessarily the inverse.

#positional_bindings ⇒ Array<Google::Datastore::V1::GqlQueryParameter>
Returns Numbered binding site @1 references the first numbered parameter, effectively using 1-based indexing, rather than the usual 0.
For each binding site numbered i in +query_string+, there must be an i-th numbered parameter. The inverse must also be true.
