Jing Zhang created FLINK-13503: ---------------------------------- Summary: Correct the behavior of `JDBCLookupFunction` Key: FLINK-13503 URL: https://issues.apache.org/jira/browse/FLINK-13503 Project: Flink Issue Type: Task Components: Connectors / JDBC Affects Versions: 1.9.0, 1.10 Reporter: Jing Zhang
The query template in `JdbcLookUpFunction` like: SELECT c, d, e, f from T where a = ? and b = ? If pass (null, 1) to `eval` method, it will generate the following query: SELECT c, d, e, f from T where a = null and b = ? Which always outputs empty records. Is this behavior reasonable? -- This message was sent by Atlassian JIRA (v7.6.14#76016)
