For this, use MySQL MIN(). Let us first create a −mysql> create table DemoTable1414 -> ( -> BookTitle varchar(40), -> BookPrice int -> ); Query OK, 0 rows affected (0.82 sec)Insert some records in the table using insert −mysql> insert into DemoTable1414 values('Deep dive using java', 560); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable1414 values('C++ in depth', 360); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable1414 values('Data structure in C', 590); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable1414 values('Algorithm in C++', 1090); Query OK, 1 ...

For this, use Regular Expression in MySQL as in the below syntax −select * from yourTableName where yourColumnName regexp '^[^ ]+[ ]+[^ ]+$';The above query will work when the two words are separated by a space. Let us first create a −mysql> create table DemoTable1412 -> ( -> Name varchar(40) -> ); Query OK, 0 rows affected (0.52 sec)Insert some records in the table using insert −mysql> insert into DemoTable1412 values('John Adam Carol'); Query OK, 1 row affected (0.09 sec) mysql> insert into DemoTable1412 values('Mike Sam'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable1412 ...

For this, use FIND_IN_SET() in MySQL and use the value from a custom variable. Let us first create a −mysql> create table DemoTable1411 -> ( -> Value int -> ) -> ; Query OK, 0 rows affected (0.50 sec)Insert some records in the table using insert −mysql> insert into DemoTable1411 values(10); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable1411 values(50); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable1411 values(60); Query OK, 1 row affected (0.08 sec)Display all records from the table using select −mysql> select * from DemoTable1411;This will produce ...

To mask data fields, use CONCAT() along with REPEAT(). Here, we will mask data fields with #. Let us first create a −mysql> create table DemoTable1410 -> ( -> Password varchar(80) -> ); Query OK, 0 rows affected (0.51 sec)Insert some records in the table using insert −mysql> insert into DemoTable1410 values('John12345678'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable1410 values('Carol_897'); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable1410 values('David_5647383'); Query OK, 1 row affected (0.17 sec)Display all records from the table using select −mysql> select * from DemoTable1410;This will produce ...
