Result of synchronized materialized view with upper column names of the base table is wrong

[LiShuMing]

Steps to reproduce the behavior (Required)

CREATE TABLE `lineitem` (\n  `L_ORDERKEY` int(11) NOT NULL COMMENT "",\n  `L_PARTKEY` int(11) NOT NULL COMMENT "",\n  `L_SUPPKEY` int(11) NOT NULL COMMENT "",\n  `L_LINENUMBER` int(11) NOT NULL COMMENT "",\n  `L_QUANTITY` decimal64(15, 2) NOT NULL COMMENT "",\n  `L_EXTENDEDPRICE` decimal64(15, 2) NOT NULL COMMENT "",\n  `L_DISCOUNT` decimal64(15, 2) NOT NULL COMMENT "",\n  `L_TAX` decimal64(15, 2) NOT NULL COMMENT "",\n  `L_RETURNFLAG` char(1) NOT NULL COMMENT "",\n  `L_LINESTATUS` char(1) NOT NULL COMMENT "",\n  `L_SHIPDATE` date NOT NULL COMMENT "",\n  `L_COMMITDATE` date NOT NULL COMMENT "",\n  `L_RECEIPTDATE` date NOT NULL COMMENT "",\n  `L_SHIPINSTRUCT` char(25) NOT NULL COMMENT "",\n  `L_SHIPMODE` char(10) NOT NULL COMMENT "",\n  `L_COMMENT` varchar(44) NOT NULL COMMENT ""\n) ENGINE=OLAP \nDUPLICATE KEY(`L_ORDERKEY`)\nCOMMENT "OLAP"\nDISTRIBUTED BY HASH(`L_ORDERKEY`) BUCKETS 10 \nPROPERTIES (\n"replication_num" = "1",\n"in_memory" = "false",\n"enable_persistent_index" = "false",\n"replicated_storage" = "true",\n"compression" = "LZ4"\n);

create MATERIALIZED view my_test_mv2 as select L_LINESTATUS, sum(L_DISCOUNT), sum(L_TAX) from lineitem group by L_LINESTATUS

Expected behavior (Required)

l_linestatus column should not be null.

Real behavior (Required)

MySQL root@127.0.0.1:tpch>  select * from my_test_mv2 [_SYNC_MV_];

StarRocks version (Required)

• You can get the StarRocks version by executing SQL select current_version()
