  • Method Details

    • getPreparedStatementHandle

      com.google.protobuf.ByteString getPreparedStatementHandle()
       Opaque handle for the prepared statement on the server.
      bytes prepared_statement_handle = 1;
      Returns:
      The preparedStatementHandle.

    • getDatasetSchema

      com.google.protobuf.ByteString getDatasetSchema()
       If a result set generating query was provided, dataset_schema contains the
 schema of the result set.  It should be an IPC-encapsulated Schema, as described in Schema.fbs.
 For some queries, the schema of the results may depend on the schema of the parameters.  The server
 should provide its best guess as to the schema at this point.  Clients must not assume that this
 schema, if provided, will be accurate.
      bytes dataset_schema = 2;
      Returns:
      The datasetSchema.

    • getParameterSchema

      com.google.protobuf.ByteString getParameterSchema()
       If the query provided contained parameters, parameter_schema contains the
 schema of the expected parameters.  It should be an IPC-encapsulated Schema, as described in Schema.fbs.
      bytes parameter_schema = 3;
      Returns:
      The parameterSchema.
