aes_decrypt function should return null for null input, but returns previous result.
MySQL [mydb]> CREATE TABLE table3
-> (
-> siteid INT DEFAULT '10',
-> citycode SMALLINT,
-> username VARCHAR(32) DEFAULT '',
-> encrypt_key varchar(255) REPLACE NULL,
-> pv BIGINT SUM DEFAULT '0'
-> )
-> AGGREGATE KEY(siteid, citycode, username)
-> DISTRIBUTED BY HASH(siteid) BUCKETS 10
-> PROPERTIES("replication_num" = "1");
Query OK, 0 rows affected (0.18 sec)
MySQL [mydb]> insert into table3 values (1,1,'aaa',AES_ENCRYPT('aaapw', 'key'),1);
Query OK, 1 row affected (0.36 sec)
{'label':'insert_82138fc5d8ca4cce-acaf4a706d0ad72f', 'status':'VISIBLE', 'txnId':'3004'}

{'label':'insert_256160d07fc440a-8d8bc70988f0e67e', 'status':'VISIBLE', 'txnId':'3005'}
MySQL [mydb]> select encrypt_key,aes_decrypt(encrypt_key,'key') from table3 order by siteid;
