Create a table if it does not already exist and insert a record in the same query with MySQL
Use CREATE TABLE IF NOT EXISTS for this as shown in the below syntax −
create table if not exists yourTableName ( yourColumnName1 dataType, yourColumnName2 dataType, yourColumnName3 dataType, . . N ) as select yourValue1 as yourColumnName1 , yourValue2 as yourColumnName2 , yourValue3 as yourColumnName3,.............................N;
Let us first create a table and insert value if the table does not already exist −
mysql> create table if not exists DemoTable ( id int, FirstName varchar(20), LastName varchar(20) ) as select 100 as id, 'John' as FirstName , 'Smith' as LastName; Query OK, 1 row affected (0.65 sec) Records: 1 Duplicates: 0 Warnings: 0
Let us now display the records −
mysql> select *from DemoTable;
This will produce the following output −
+------+-----------+----------+ | id | FirstName | LastName | +------+-----------+----------+ | 100 | John | Smith | +------+-----------+----------+ 1 row in set (0.00 sec)
