How to quote values using MySQL group_concat?
You can quote values using concat() and grop_concat() function from MySQL. The syntax is as follows −
SELECT GROUP_CONCAT(CONCAT(' '' ', yourColumnName, ' '' ' )) as anyVariableName from yourTableName;To understand the above syntax, let us create a table. The query to create a table is as follows −
mysql> create table Group_ConcatDemo -> ( -> Id int NOT NULL AUTO_INCREMENT, -> Value int, -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (1.56 sec)
Now you can insert some records in the table using insert command. The query is as follows −
mysql> insert into Group_ConcatDemo(Value) values(100); Query OK, 1 row affected (0.24 sec) mysql> insert into Group_ConcatDemo(Value) values(120); Query OK, 1 row affected (0.22 sec) mysql> insert into Group_ConcatDemo(Value) values(234); Query OK, 1 row affected (0.11 sec) mysql> insert into Group_ConcatDemo(Value) values(2345); Query OK, 1 row affected (0.24 sec) mysql> insert into Group_ConcatDemo(Value) values(5678); Query OK, 1 row affected (0.14 sec) mysql> insert into Group_ConcatDemo(Value) values(86879); Query OK, 1 row affected (0.16 sec)
Display all records from the table using select statement. The query is as follows −
mysql> select *from Group_ConcatDemo;
The following is the output −
+----+-------+ | Id | Value | +----+-------+ | 1 | 100 | | 2 | 120 | | 3 | 234 | | 4 | 2345 | | 5 | 5678 | | 6 | 86879 | +----+-------+ 6 rows in set (0.00 sec)
Here is the query to quote values using group_concat() −
mysql> select GROUP_CONCAT(CONCAT('''', Value, '''' )) as SingleQuote from Group_ConcatDemo;The following is the output −
+-----------------------------------------+ | SingleQuote | +-----------------------------------------+ | '100','120','234','2345','5678','86879' | +-----------------------------------------+ 1 row in set (0.09 sec)
