Can I use two where clauses like “SELECT * FROM table WHERE condition1 and condition2” in MySQL?
Yes, you need to use AND or OR operator. The syntax is as follows −
select *from yourTableName where yourColumnName1=yourValue AND yourColumnName=yourValue';
For AND condition, both conditions must be true otherwise you will get an empty set.
To understand the above syntax, let us create a table. The query to create a table is as follows −
mysql> create table WhereDemo -> ( -> Id int, -> Name varchar(20) -> ); Query OK, 0 rows affected (0.56 sec)
Now you can insert some records in the table using insert command. The query is as follows −
mysql> insert into WhereDemo values(101,'Maxwell'); Query OK, 1 row affected (0.14 sec) mysql> insert into WhereDemo values(110,'David'); Query OK, 1 row affected (0.21 sec) mysql> insert into WhereDemo values(1000,'Carol'); Query OK, 1 row affected (0.18 sec) mysql> insert into WhereDemo values(1100,'Bob'); Query OK, 1 row affected (0.47 sec) mysql> insert into WhereDemo values(115,'Sam'); Query OK, 1 row affected (0.23 sec)
Display all records from the table using select statement. The query is as follows −
mysql> select *from WhereDemo;
The following is the output −
+------+---------+ | Id | Name | +------+---------+ | 101 | Maxwell | | 110 | David | | 1000 | Carol | | 1100 | Bob | | 115 | Sam | +------+---------+ 5 rows in set (0.00 sec)
Here is the query to select all records from the table with more than one condition −
mysql> select *from WhereDemo where Id=1100 AND Name='Bob';
The following is the output −
+------+------+ | Id | Name | +------+------+ | 1100 | Bob | +------+------+ 1 row in set (0.00 sec)
