Flink SQL create table 关键字 table 加反引号 解析失败是什么情况？

我的数据源 json 里有 database, table 字段，想解析出来，是保留关键字，我加了反引号，但是还是报错，这是为什么呢

val bsSettings = EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build() val bsTableEnv = StreamTableEnvironment.create(env, bsSettings) val sourceTable = """CREATE TABLE my_kafak_source ( | table varchar, | database varchar, | data row < transaction_id varchar, | user_id int, | amount int, | >, | maxwell_ts bigint, | ts_watermark as TO_TIMESTAMP(FROM_UNIXTIME(maxwell_ts/1000)) |) WITH ( |)""".stripMargin

error

The program finished with the following exception:

org.apache.flink.client.program.ProgramInvocationException: The main method caused an error: SQL parse failed. Encountered "table" at line 1, column 8. Was expecting one of: "ABS" ... "ALL" ... "ARRAY" ... "AVG" ... "CARDINALITY" ... "CASE" ... "CAST" ... "CEIL" ...
