[nextdreamblue]

Steps to reproduce the behavior (Required)

1. CREATE TABLE test1 ( k1 int(11) NULL COMMENT "", k2 int(11) NULL COMMENT "", k3 varchar(300) NULL COMMENT "", k4 varchar(30) NULL COMMENT "", k5 date NULL COMMENT "", new_column0 int(11) NULL DEFAULT "0" COMMENT "" ) ENGINE=OLAP UNIQUE KEY(k1, k2, k3) COMMENT "OLAP" DISTRIBUTED BY HASH(k1, k2, k3) BUCKETS 1 PROPERTIES ( "compression" = "LZ4", "fast_schema_evolution" = "true", "replicated_storage" = "true", "replication_num" = "1" );

2. insert into test1 values(1,2,'a','b','2020-01-01');

3. by java prepare stmt preparedStatement = connect.prepareStatement("select * from test1 where k2 = ? and k3 = ?"); preparedStatement.setString(1, "2"); preparedStatement.setString(2, "a"); stmt.execute("ALTER table test1 ADD COLUMN new_column0 INT default \"0\";"); stmt.execute("INSERT INTO test1 VALUES(2, 3, \"aa\", \"bb\", \"2030-01-02\", 1)"); preparedStatement.setString(1, "3"); preparedStatement.setString(2, "aa"); // 执行查询 resultSet = preparedStatement.executeQuery(); will get exception by java
