The MySQL converts NVARCHAR() to VARCHAR(). NVARCHAR stands for National Varchar in MySQL. Let us first create a table with one of the columns “StudentName” as NVARCHAR −
mysql> create table DemoTable ( StudentName NVARCHAR(40), StudentCountryName VARCHAR(50) ); Query OK, 0 rows affected, 1 warning (0.49 sec)
Let us check the description of the table −
mysql> desc DemoTable;
This will produce the following output. As you can see below, the StudentName column with NVARCHAR type is automatically converted to VARCHAR in MySQL −
+--------------------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +--------------------+-------------+------+-----+---------+-------+ | StudentName | varchar(40) | YES | | NULL | | | StudentCountryName | varchar(50) | YES | | NULL | | +--------------------+-------------+------+-----+---------+-------+ 2 rows in set (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Chris','US'); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable values('Tom','UK'); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable values('David','AUS'); Query OK, 1 row affected (0.11 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-------------+--------------------+ | StudentName | StudentCountryName | +-------------+--------------------+ | Chris | US | | Tom | UK | | David | AUS | +-------------+--------------------+ 3 rows in set (0.00 sec)
