How to quote values of single column using GROUP_CONCAT and CONCAT with DISTINCT in MySQL?
For this, you can use group_concat() along with replace(). Let us first create a table −
mysql> create table DemoTable1799 ( EmployeeId varchar(20) ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1799 values('101,102,103,104');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1799 values('106,109');
Query OK, 1 row affected (0.00 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1799;
This will produce the following output:
+-----------------+ | EmployeeId | +-----------------+ | 101,102,103,104 | | 106,109 | +-----------------+ 2 rows in set (0.00 sec)
Here is the query to quote values of single column using group_concat and concat with distinct −
mysql> select group_concat(distinct concat("'", replace(EmployeeId, "," , "','") , "'")) as Output from DemoTable1799;
This will produce the following output −
+-------------------------------------+ | Output | +-------------------------------------+ | '101','102','103','104','106','109' | +-------------------------------------+ 1 row in set (0.00 sec)
