SQL
`RENAME COLUMN`
Rename a column of a table:  
```sql
ALTER TABLE integers RENAME i TO j;
ALTER TABLE integers RENAME COLUMN j TO k;
```  
The `RENAME COLUMN` clause renames a single column within a table. Any constraints that rely on this name (e.g., `CHECK` constraints) are automatically updated. However, note that any views that rely on this column name are **not** automatically updated.
