How to set a string with hyphen and numbers in MySQL varchar?
To set a string with hyphen and numbers, you need to use single quotes. For example, 'Customer-1234-899', 'Customer-9383-901', etc.
Let us first create a table −
mysql> create table DemoTable -> ( -> CustomerId varchar(100) -> ); Query OK, 0 rows affected (0.70 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Customer-1234-899');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('Customer-8373-900');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable values('Customer-9383-901');
Query OK, 1 row affected (0.20 sec)Display all records from the table using select statement −
mysql> select *from DemoTable
Output
This will produce the following output −
+-------------------+ | CustomerId | +-------------------+ | Customer-1234-899 | | Customer-8373-900 | | Customer-9383-901 | +-------------------+ 3 rows in set (0.00 sec)
Here is the query to display how we can select a single value −
mysql> select *from DemoTable where (CustomerId='Customer-8373-900');
Output
This will produce the following output −
+-------------------+ | CustomerId | +-------------------+ | Customer-8373-900 | +-------------------+ 1 row in set (0.00 sec)
