MySQL Append Column

This example illustrates how to append two column values of a table.
Appending columns values can be performed using CONCAT() function. By this
function, values of columns can be concatenated and made them a single value. In this example, we are concatenating the value
of "studentid", "sectionid", "courseid",
"time" columns for each row of the "mca"
table.
Table: "mca"
Table
|
+-----------+-----------+----------+----------------------------------+
| studentid | sectionid | courseid | time |
+-----------+-----------+----------+----------------------------------+
| 3 | 3 | 3 | Mon 14:30-16:00 |
| 2 | 2 | 5 | Mon 11:30-12:00, Thu 09:00-11:00 |
| 1 | 1 | 6 | Mon 09:30-11:00 |
+-----------+-----------+----------+----------------------------------+
|
Query to concatenate column values:
Query
|
select studentid, CONCAT(studentid, sectionid, courseid, time) FROM mca;
|
Output
|
+-----------+----------------------------------------------+
| studentid | CONCAT(studentid, sectionid, courseid, time) |
+-----------+----------------------------------------------+
| 3 | 333Mon 14:30-16:00 |
