To drop the NOT NULL constraints from a table in SQL, you would need to use the ALTER TABLE statement. However, you cannot directly drop a NOT NULL constraint in SQL. You have to change the column's data type to allow NULLs. Here's how you can do it:

1. First, identify the column name and its data type. You can do this by using the DESCRIBE statement. For example:

```sql
DESCRIBE EMP;
```

This will give you a list of all the columns in the EMP table along with their data types and whether they are nullable or not.

2. Once you have identified the column, you can modify it to allow NULLs. For example, if you have a column named 'column_name' of type 'column_type' and you want to drop its NOT NULL constraint, you would do:

```sql
ALTER TABLE EMP MODIFY column_name column_type NULL;
```

Replace 'column_name' and 'column_type' with the actual column name and its data type.

Please note that you need to have the ALTER privilege for the table. Also, this operation will commit the current transaction, and may take a long time if the table has many rows.
