MySQL Append String

We use CONCAT() function to append the values of columns.

MySQL Append String

     

This example illustrates how to append string of different column.

We use CONCAT() function to append the values of columns.

In this example, we are concatenating:

1. The value of "time" column,
2. String ", section" and
3. The value of "sectionid" column

for each row of the "mca" table.

Query to create table "mca":

Query

CREATE TABLE mca (
    studentid  INT NOT NULL,
    sectionid  INT NOT NULL,
    courseid   INT NOT NULL PRIMARY KEY,
    time       VARCHAR(50)
 );

Query to insert values in table:

Query

INSERT INTO mca (studentid,sectionid,courseid,time) VALUES (1,1,6,'Mon 09:30-11:00');
INSERT INTO mca (studentid,sectionid,courseid,time) VALUES (2,2,5,'Mon 11:30-12:00, Thu 09:00-11:00');
INSERT INTO mca (studentid,sectionid,courseid,time) VALUES (3,3,3,'Mon 14:30-16:00');

Query to concatenate value to column values:

Query

SELECT studentid, CONCAT(time, ', section ', sectionid) AS ClassDetails FROM mca;

Output

+-----------+---------------------------------------------+
| studentid | ClassDetails                                |
+-----------+---------------------------------------------+
| 3         | Mon 14:30-16:00, section 3                  |
| 2         | Mon 11:30-12:00, Thu 09:00-11:00, section 2 |
| 1         | Mon 09:30-11:00, section 1                  |
+-----------+---------------------------------------------+
