How to select records beginning with certain numbers in MySQL?

The optimal solution to select records beginning with certain numbers, use MySQL LIKE operator. Let us first create a table −

mysql> create table DemoTable
(
   ClientId bigint,
   ClientName varchar(40)
);
Query OK, 0 rows affected (0.82 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values(23568777,'Chris Brown');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable values(9085544,'John Doe');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values(9178432,'John Doe');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable values(9078482,'David Miller');
Query OK, 1 row affected (0.17 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+----------+--------------+
| ClientId | ClientName   |
+----------+--------------+
| 23568777 | Chris Brown  |
| 9085544  | John Doe     |
| 9178432  | John Doe     |
| 9078482  | David Miller |
+----------+--------------+
4 rows in set (0.00 sec)

Following is the query to select records beginning with certain numbers in MySQL −

mysql> select *from DemoTable where ClientId LIKE '90%';

This will produce the following output −

+----------+--------------+
| ClientId | ClientName   |
+----------+--------------+
| 9085544  | John Doe     |
| 9078482  | David Miller |
+----------+--------------+
2 rows in set (0.00 sec)
