Syntax error Get rows that have common value from the same table with different id in MySQL

Get rows that have common value from the same table with different id in MySQL

For this, you can use GROUP BY HAVING clause. Let us first create a table −

mysql> create table DemoTable1467
   -> (
   -> Id int,
   -> Name varchar(20)
   -> );
Query OK, 0 rows affected (0.64 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1467 values(100,'Chris');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable1467 values(110,'David');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable1467 values(120,'Mike');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable1467 values(100,'Chris');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable1467 values(130,'Carol');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable1467 values(100,'Chris');
Query OK, 1 row affected (0.20 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1467;

This will produce the following output −

+------+-------+
| Id   | Name |
+------+-------+
|  100 | Chris |
|  110 | David |
|  120 | Mike  |
|  100 | Chris |
|  130 | Carol |
|  100 | Chris |
+------+-------+
6 rows in set (0.00 sec)

Here is the query to get rows that have common value from the same table with different id −

mysql> select Id,Name,count(*) as IdCount from DemoTable1467
   -> group by Id
   -> having IdCount > 2;

This will produce the following output −

+------+-------+---------+
| Id   | Name |  IdCount |
+------+-------+---------+
|  100 | Chris |       3 |
+------+-------+---------+
1 row in set (0.00 sec)
