[GitHub] [incubator-doris] EmmyMiao87 opened a new issue #5083: Inaccurate error message when creating materialized view
EmmyMiao87 opened a new issue #5083:
URL: https://github.com/apache/incubator-doris/issues/5083
**Describe the bug**
If user wants to create materialized view with a mv column which is transformed from original column in agg family table,
Doris will throw a inaccurate error message "Column[mv_xxx] does not exist"
This is a confusing error message, the user does not know what wrong behavior he has done.
**To Reproduce**
Steps to reproduce the behavior:
1. create agg table
```
CREATE TABLE example_table ( k1 TINYINT, k2 DECIMAL(10, 2) DEFAULT "10.5", v1 int replace, v2 int replace ) ENGINE=olap AGGREGATE KEY(k1, k2) DISTRIBUTED BY HASH(k1) BUCKETS 32 PROPERTIES ("replication_num"="1");
```
2. create materialized view
```
create materialized view mv as select k1, k2, bitmap_union(to_bitmap(v1)) from example_table group by k1,k2;
ERROR 1064 (HY000): Unexpected exception: Column[mv_bitmap_union_v1] does not exist
```
**Expected behavior**
```
ERROR 1064 (HY000): errCode = 2, detailMessage = The mv column of agg or uniq table cannot be transformed from original column[v1]
```
