Instance Attribute Details

#allow_literals ⇒ Boolean Also known as: allow_literals?

When false, the query string must not contain any literals and instead must bind all values. For example, SELECT * FROM Kind WHERE a = 'string literal' is not allowed, while SELECT * FROM Kind WHERE a = @value is. Corresponds to the JSON property allowLiterals

Returns:

  • (Boolean)

  @allow_literals
end

#named_bindings ⇒ Hash<String,Google::Apis::DatastoreV1::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. Key must match regex A-Za-z_$*, must not match regex __.*__, and must not be "". Corresponds to the JSON property namedBindings

Returns:

def named_bindings
  @named_bindings
end

#positional_bindings ⇒ Array<Google::Apis::DatastoreV1::GqlQueryParameter>

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. Corresponds to the JSON property positionalBindings

Returns:
