MySQL query to append a number of stars based on string length?
For this, you can use RPAD(). Let us first create a table −
mysql> create table DemoTable1626 -> ( -> Name varchar(20) -> ); Query OK, 0 rows affected (0.37 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1626 values('Chris'); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable1626 values('Bob'); Query OK, 1 row affected (0.34 sec) mysql> insert into DemoTable1626 values('Robert'); Query OK, 1 row affected (0.13 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1626;
This will produce the following output −
+--------+ | Name | +--------+ | Chris | | Bob | | Robert | +--------+ 3 rows in set (0.00 sec)
Here is the query to append number of stars based on string length −
mysql> select rpad(Name,if(length(Name) >= 5,10,7),'*') from DemoTable1626;
This will produce the following output −
+-------------------------------------------+ | rpad(Name,if(length(Name) >= 5,10,7),'*') | +-------------------------------------------+ | Chris***** | | Bob**** | | Robert**** | +-------------------------------------------+ 3 rows in set (0.00 sec)
