Caizhi Weng updated FLINK-22016:
--------------------------------
Description:
Add the following test case to {{PushFilterIntoTableSourceScanRuleTest}} to
reproduce this bug:
{code:java}
@Test
public void myTest() {
String ddl =
"CREATE TABLE MTable ("
+ " a STRING,"
+ " b STRING"
+ ") WITH ("
+ " 'connector' = 'values',"
+ " 'bounded' = 'true'"
+ ")";
util().tableEnv().executeSql(ddl);
util().verifyRelPlan("WITH MView AS (SELECT CASE\n"
+ " WHEN a = b THEN a\n"
+ " ELSE CAST(NULL AS STRING)\n"
+ " END AS a\n"
+ " FROM MTable)\n"
+ "SELECT a FROM MView WHERE a IS NOT NULL");
}
{code}
The exception stack is
{code}
org.apache.flink.table.api.ValidationException: Data type 'STRING NOT NULL'
does not support null values.
