如何使用 INSERT() 函数将新字符串插入 MySQL 表的列值中?

To do this, we need to use the column name as the first parameter of the INSERT() function, that is, at the position of the original string. The following example will demonstrate it:

Example

Suppose we want to add "/Old" to the value of the "year_of_admission" column of the "Student" table, then we need to write the following query:

mysql> Select INSERT(year_of_admission,5,0,'/Old')As 'Old Admissions' From Student;

+-----------------+
| Old Admissions  |
+-----------------+
| 2001/Old        |
| 2010/Old        |
| 2009/Old        |
| 2017/Old        |
| 2000/Old        |
+-----------------+

5 rows in set (0.00 sec)

We can also use WHERE clause in the above query as shown below, -

mysql> Select INSERT(year_of_admission,5,0,&#39;/Old&#39;)As &#39;Old Admissions&#39; From Student WHERE year_of_admission < &#39;2017&#39;;

+----------------+
| Old Admissions |
+----------------+
| 2001/Old       |
| 2010/Old       |
| 2009/Old       |
| 2000/Old       |
+----------------+

4 rows in set (0.00 sec)
