+/// \brief Get the schema for bound parameters.
+///
+/// This should be called after AdbcStatementPrepare. This retrieves
+/// an Arrow schema describing the number, names, and types of the
+/// parameters in a parameterized statement. Not all drivers will
+/// support this. If the name of a parameter cannot be determined,
+/// the name of the corresponding field in the schema will be an empty
+/// string. Similarly, if the type cannot be statically determined,
+/// the type of the corresponding field will be NA (NullType).
Review Comment:
should we also explicitly state/define that the order of the columns in the
schema should match the ordinal position of the parameters and if a named
parameter is used multiple times in the query, it should only appear once in
the schema?
