zhengbm updated FLINK-11862:
----------------------------
Summary: many differents query on same stream cause second condition of
where of second query error (was: 在同一条流上进行多次不同的sql，第二个sql的where条件不可用)

>
> Key: FLINK-11862
> URL: https://issues.apache.org/jira/browse/FLINK-11862
> Project: Flink
> Issue Type: Bug
> Components: API / Table SQL
> Affects Versions: 1.7.2
> Environment: flink 1.7版本 java 1.8
> Reporter: zhengbm
> Priority: Major
>
> List<String> fields = Lists.newArrayList("rawMessage","timestamp");
> Schema schema = new Schema();
> for (int i = 0; i < fields.size(); i++)
> { schema.field(fields.get(i), Types.STRING()).from(fields.get(i)); }
> tableEnvironment.connect(new Kafka()
> .version("0.8")
> .properties(properties)
> .topic("raw_playtime_h5_source")
> .startFromLatest()
> )
> .withFormat(new Json().failOnMissingField(false).deriveSchema())
> .withSchema(schema)
> .inAppendMode()
> .registerTableSource("t1");
> Table table2 = tableEnvironment
> .sqlQuery("select maps,`timestamp`,CARDINALITY(maps) AS maps_length ,1 as
> flash from t1 ,LATERAL TABLE(split(rawMessage,'
> t')) as T(maps) ");
> tableEnvironment.registerTable("t2", table2);
> Table table = tableEnvironment.sqlQuery("select `timestamp`,maps_length from
> t2 where maps_length>0");
> TypeInformation typeInformation = table.getSchema().toRowType();
> String[] columns = table.getSchema().getFieldNames();
> DataStream<String> dataStream = tableEnvironment
> .toAppendStream(table, typeInformation)
> .map(new PhysicTransformMap(columns, 0));
> dataStream.print();
> try
> { env.execute(); }
> catch (Exception e)
> { e.printStackTrace(); }
> {color:#d04437}注：kafka中的数据流格式如下\{"timestamp" :
> "xxxx","rawMessage":"xxx\txxx\txxxx\t"}（如果where条件换成timestamp则可用，或者把where条件去掉程序运行正常）函数split是把一条string切分为map结构{color}
