MySQL query to update all records to capitalize only the first letter and set all others in lowercase
Let us first create a table −
mysql> create table DemoTable2017 -> ( -> Name text -> ); Query OK, 0 rows affected (0.55 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable2017 values('JOHN SMITH,MYSQL');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable2017 values('DAVID MILLER,MONGODB');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable2017 values('CHRIS BROWN,JAVA');
Query OK, 1 row affected (0.11 sec)Display all records from the table using select statement −
mysql> select *from DemoTable2017;
This will produce the following output −
+----------------------+ | Name | +----------------------+ | JOHN SMITH,MYSQL | | DAVID MILLER,MONGODB | | CHRIS BROWN,JAVA | +----------------------+ 3 rows in set (0.00 sec)
Here is the query to set only the first letter in capital and rest in lower case −
mysql> update DemoTable2017 -> set Name=REPLACE(CONCAT(UPPER(LEFT(Name, 1)), LOWER(SUBSTRING(Name, 2))),' , ', ', '); Query OK, 3 rows affected (0.16 sec) Rows matched: 3 Changed: 3 Warnings: 0
Let us check the table records once again −
mysql> select *from DemoTable2017;
This will produce the following output −
+----------------------+ | Name | +----------------------+ | John smith,mysql | | David miller,mongodb | | Chris brown,java | +----------------------+ 3 rows in set (0.00 sec)
