Mryange opened a new pull request, #57376:
URL: https://github.com/apache/doris/pull/57376
### What problem does this PR solve?
The following code can compile:
```C++
void foo(const ColumnInt64& bit_col) {}
void test() { int64_t a = 123; foo(a); }
```
This is because we have the following constructor: ColumnVector(const size_t
n) : data(n) {}
The make_set function incorrectly uses this pattern, causing wrong results.
before
```
mysql> SELECT id, make_set(1, col2, 'default1', 'default2') FROM test_local;
+------+-------------------------------------------+
| id | make_set(1, col2, 'default1', 'default2') |
+------+-------------------------------------------+
| 1 | default1,default2 |
| 3 | default1,default2 |
| 5 | default1,default2 |
| 2 | default1,default2 |
| 4 | default1,default2 |
+------+-------------------------------------------+
```
now
```
mysql> SELECT id, make_set(1, col2, 'default1', 'default2') FROM test_local;
+------+-------------------------------------------+
| id | make_set(1, col2, 'default1', 'default2') |
+------+-------------------------------------------+
| 2 | boundary_value |
| 4 | zero_value |
| 3 | negative_boundary |
| 5 | null_value |
| 1 | test_string |
+------+-------------------------------------------+
```
To prevent this from happening again, I made the constructor explicit.
