Apache Derby DB在“ PARTITION”上返回语法错误

Question

当尝试在derbyDB上使用“ PARTITION BY”时，我因“语法错误”而被拒绝：遇到“ PARTITION”。

我正在尝试选择数据，并定义了以下列：

import tensorflow as tf def representative_dataset_gen(): for _ in range(num_calibration_steps): # Get sample input data as a numpy array in a method of your choosing. yield [input] converter = tf.lite.TFLiteConverter.from_saved_model(saved_model_dir) converter.optimizations = [tf.lite.Optimize.DEFAULT] converter.representative_dataset = representative_dataset_gen tflite_quant_model = converter.convert()

我还查看了以下文档：

• https://docs.microsoft.com/en-us/sql/t-sql/functions/row-number-transact-sql?view=sql-server-2017

• https://wiki.apache.org/db-derby/OLAPOperations

但是derbyDB拒绝“语法错误：遇到'PARTITION'”

我希望derbyDB支持按文档所示进行分区，并选择并显示行号。
