Name Description
data array

Optional. Data for populating the Message object.
↳ query_string string

A string of the format described here.
↳ allow_literals bool

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.
↳ named_bindings array|Google\Protobuf\Internal\MapField

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_$][A-Za-z_$0-9]*, must not match regex __.*__, and must not be "".
↳ positional_bindings array<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.
