To select multiple values, you can use where clause with OR and IN operator.
The syntax is as follows −
Case 1 − Using OR
select *from yourTablename where yourColumnName = value1 or yourColumnName = value2 or yourColumnName = value3,.........N;
Case 2 − Using IN
select *from yourTableName where yourColumnName IN(value1,value2,....N);
To understand the above syntax, let us create a table. The following is the query to create a table −
mysql> create table selectMultipleValues −> ( −> BookId int, −> BookName varchar(200) −> ); Query OK, 0 rows affected (1.68 sec)
Now you can insert some records in the table with the help of insert command. The query to insert records is as follows −
mysql> insert into selectMultipleValues values(100,'Introduction to C'); Query OK, 1 row affected (0.18 sec) mysql> insert into selectMultipleValues values(101,'Introduction to C++'); Query OK, 1 row affected (0.19 sec) mysql> insert into selectMultipleValues values(103,'Introduction to java'); Query OK, 1 row affected (0.14 sec) mysql> insert into selectMultipleValues values(104,'Introduction to Python'); Query OK, 1 row affected (0.14 sec) mysql> insert into selectMultipleValues values(105,'Introduction to C#'); Query OK, 1 row affected (0.13 sec) mysql> insert into selectMultipleValues values(106,'C in Depth'); Query OK, 1 row affected (0.15 sec)
Display all records from the table with the help of select statement. The query is as follows −
mysql> select *from selectMultipleValues;
The following is the output −
+--------+------------------------+ | BookId | BookName | +--------+------------------------+ | 100 | Introduction to C | | 101 | Introduction to C++ | | 103 | Introduction to java | | 104 | Introduction to Python | | 105 | Introduction to C# | | 106 | C in Depth | +--------+------------------------+ 6 rows in set (0.00 sec)
The following is the query to select multiple values with the help of OR operator.
Case 1 − Using OR operator.
mysql> select *from selectMultipleValues where BookId = 104 or BookId = 106;
The following is the output −
+--------+------------------------+ | BookId | BookName | +--------+------------------------+ | 104 | Introduction to Python | | 106 | C in Depth | +--------+------------------------+ 2 rows in set (0.00 sec)
Case 2 − Using In operator.
The following is the query to select multiple values with the help of IN operator.
mysql> select *from selectMultipleValues where BookId in(104,106);
The following is the output −
+--------+------------------------+ | BookId | BookName | +--------+------------------------+ | 104 | Introduction to Python | | 106 | C in Depth | +--------+------------------------+ 2 rows in set (0.00 sec)
