## Proposed changes
Issue Number: close #xxx
<!--Describe your changes.-->
```sql
CREATE TABLE test1 (
x varchar NOT NULL,
id varchar NOT NULL
)
ENGINE=OLAP
UNIQUE KEY(`x`)COMMENT "OLAP"
DISTRIBUTED BY HASH(`x`)
BUCKETS 96
PROPERTIES (
"replication_num" = "1",
"enable_unique_key_merge_on_write" = "true"
);
insert into test1 values("a", "a"), ("bb", "bb"), ("ccc", "ccc");
delete from test where length(x) = 2
```
after delete, the table will be empty because the expression is analyzed
when build insert stmt. We fix it by copying the expression and analyze the
copy.
