SELECT * FROM Kind WHERE a = @value
is.

PositionalBindings
public RepeatedField<GqlQueryParameter> PositionalBindings { get; }
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.
