[jira] [Commented] (FLINK-27965) EXPLAIN PLAN FOR does not work for insert clause with static partition
[ https://issues.apache.org/jira/browse/FLINK-27965?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17553119#comment-17553119 ]
Jane Chan commented on FLINK-27965:
-----------------------------------
Another case
Add "explain plan for" under TableSinkJsonPlanTest
{code:java}
@Test
public void testPartitioning() {
String sinkTableDdl =
"CREATE TABLE MySink (\n"
+ " a bigint,\n"
+ " b int,\n"
+ " c varchar\n"
+ ") partitioned by (c) with (\n"
+ " 'connector' = 'filesystem',\n"
+ " 'format' = 'testcsv',\n"
+ " 'path' = '/tmp')";
tEnv.executeSql(sinkTableDdl);
util.verifyJsonPlan("insert into MySink partition (c='A') select a, b from MyTable"); // ok
tEnv.explainSql("insert into MySink partition (c='A') select a, b from MyTable"); // ok
tEnv.executeSql(
"explain plan for "
+ "insert into MySink partition (c='A') select a, b from MyTable")
.print(); // throw exception
} {code}
