How to output MySQL query results in CSV format and display it on the screen, not a file?
To get the output MySQL query result in CSV format, use concat(). The syntax is as follows −
mysql> select concat(StudentId,',',StudentName,',',StudentAge) as CSVFormat from CSVFormatOutputs;
To understand the above syntax, let us create a table. The query to create a table is as follows−
mysql> create table CSVFormatOutputs -> ( -> StudentId int not null auto_increment, -> StudentName varchar(20), -> StudentAge int, -> PRIMARY KEY(StudentId) -> ); Query OK, 0 rows affected (1.15 sec)
Insert some records in the table using insert command. The query is as follows −
mysql> insert into CSVFormatOutputs(StudentName,StudentAge) values('Mike',23);
Query OK, 1 row affected (0.26 sec)
mysql> insert into CSVFormatOutputs(StudentName,StudentAge) values('John',26);
Query OK, 1 row affected (0.19 sec)
mysql> insert into CSVFormatOutputs(StudentName,StudentAge) values('Sam',19);
Query OK, 1 row affected (0.20 sec)
mysql> insert into CSVFormatOutputs(StudentName,StudentAge) values('Carol',27);
Query OK, 1 row affected (0.59 sec)
mysql> insert into CSVFormatOutputs(StudentName,StudentAge) values('Bob',24);
Query OK, 1 row affected (0.15 sec)Display all records from the table using select statement. The query is as follows−
mysql> select *from CSVFormatOutputs;
The following is the output −
+-----------+-------------+------------+ | StudentId | StudentName | StudentAge | +-----------+-------------+------------+ | 1 | Mike | 23 | | 2 | John | 26 | | 3 | Sam | 19 | | 4 | Carol | 27 | | 5 | Bob | 24 | +-----------+-------------+------------+ 5 rows in set (0.00 sec)
Here is the MySQL query to get the output in CSV (Comma Separated Value) format to the screen using contact() method−
mysql> select concat(StudentId,',',StudentName,',',StudentAge) as CSVFormat from CSVFormatOutputs;
The following is the output displaying the CSV format records−
+------------+ | CSVFormat | +------------+ | 1,Mike,23 | | 2,John,26 | | 3,Sam,19 | | 4,Carol,27 | | 5,Bob,24 | +------------+ 5 rows in set (0.00 sec)
