How to assign the result of a MySQL query into a variable?

Use @anyVariableName to assign the result of a query into a variable. Let us first create a table −

mysql> create table DemoTable1864      (      Id int,      FirstName varchar(20),      LastName varchar(20)      ); Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1864 values(101,'Chris','Brown'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1864 values(102,'David','Miller'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1864 values(103,'Adam','Smith'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1864 values(104,'John','Doe'); Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from  DemoTable1864;

This will produce the following output −

+------+-----------+----------+ | Id   | FirstName | LastName | +------+-----------+----------+ |  101 | Chris     |    Brown | |  102 | David     |   Miller | |  103 | Adam      |    Smith | |  104 | John      |      Doe | +------+-----------+----------+ 4 rows in set (0.00 sec)

Here is the query to assign the result of a query into a variable −

mysql> select @fName:=FirstName,@lName:=LastName      from DemoTable1864      where Id=103;

This will produce the following output −

+-------------------+------------------+ | @fName:=FirstName | @lName:=LastName | +-------------------+------------------+ | Adam              |            Smith | +-------------------+------------------+ 1 row in set (0.00 sec)
