Create a dynamic table name from current year in MySQL like 2019


To create a table name like year (2019), use PREPARE statement. Let us first create a table −

mysql> create table DemoTable1959
   (
   UserName varchar(20)
   );
Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1959 values('Chris');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1959 values('David');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1959 values('Bob');
Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1959;

This will produce the following output −

+----------+
| UserName |
+----------+
| Chris    |
| David    |
| Bob      |
+----------+
3 rows in set (0.00 sec)

Here is the query to create a dynamic table name from current year

mysql> set @dynamicQuery = CONCAT('create table `', date_format(curdate(),'%Y'), '` as select UserName from DemoTable1959');
Query OK, 0 rows affected (0.00 sec)
mysql> prepare st from @dynamicQuery;
Query OK, 0 rows affected (0.00 sec)
Statement prepared
mysql> execute st;
Query OK, 3 rows affected (0.00 sec)
Records: 3  Duplicates: 0  Warnings: 0

Display all records from the table using select statement. Here the current year is 2019 −

mysql> select * from `2019`;

This will produce the following output −

+----------+
| UserName |
+----------+
| Chris    |
| David    |
| Bob      |
+----------+
3 rows in set (0.00 sec)
