目前无法通过t.* 将嵌套的字段查询出来。
val schema = tEnv.executeSql(
"""
| SELECT t.* FROM (
| SELECT EvtParser(request) as t FROM parsed_nginx_log
| )
|""".stripMargin).getTableSchema
其中自定义函数 EvtParser 定义如下。
@DataTypeHint("ROW<evt STRING, app STRING, uid STRING, ts STRING, url
STRING, action STRING>")
def eval(line: String) = {
.....
}
详细报错信息：
java.lang.RuntimeException: Error while applying rule

[rel#63:LogicalProject.NONE.any.None:
0.[NONE].[NONE](input=RelSubset#62,exprs=[EvtParser($3).evt,
EvtParser($3).app, EvtParser($3).uid, EvtParser($3).ts, EvtParser($3).url,
