Hi,
需要将 null cast 成某个具体的值,比如: if(type=1,2,cast(null as int)) Best, Hailong 在 2020-11-10 19:14:44,"丁浩浩" <[email protected]> 写道: >Select > id, > name, > if(type=1,2,null) >From > user ; >当我执行上面的sql的时候提示我 >[ERROR] Could not execute SQL statement. Reason: >org.apache.calcite.sql.validate.SqlValidatorException: Illegal use of ‘NULL’ >是无法将null展示吗?
