How to add a where clause in a MySQL Insert statement?
You need to use UPDATE statement for this.
The syntax is as follows
update yourTableName set yourColumnName1=yourValue1,yourColumnName2=yourValue2,....N where yourCondition;
Let us create a table for our example
mysql> create table addWhereClauseDemo -> ( -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> StudentName varchar(30), -> StudentPassword varchar(40) -> ); Query OK, 0 rows affected (0.45 sec)
Insert some records in the table using insert command.
The query is as follows
mysql> insert into addWhereClauseDemo(StudentName,StudentPassword) values('John','John123456');
Query OK, 1 row affected (0.14 sec)
mysql> insert into addWhereClauseDemo(StudentName,StudentPassword) values('Carol','99999');
Query OK, 1 row affected (0.24 sec)
mysql> insert into addWhereClauseDemo(StudentName,StudentPassword) values('Bob','OO7Bob');
Query OK, 1 row affected (0.16 sec)
mysql> insert into addWhereClauseDemo(StudentName,StudentPassword) values('David','David321');
Query OK, 1 row affected (0.26 sec)Display all records from the table using select statement.
The query is as follows
mysql> select *from addWhereClauseDemo;
The following is the output
+-----------+-------------+-----------------+ | StudentId | StudentName | StudentPassword | +-----------+-------------+-----------------+ | 1 | John | John123456 | | 2 | Carol | 99999 | | 3 | Bob | OO7Bob | | 4 | David | David321 | +-----------+-------------+-----------------+ 4 rows in set (0.00 sec)
Here is the query to add a where clause i.e. updating the records
mysql> update addWhereClauseDemo -> set StudentName='Maxwell',StudentPassword='Maxwell44444' where StudentId=4; Query OK, 1 row affected (0.18 sec) Rows matched: 1 Changed: 1 Warnings: 0
Let us check the table records once again.
The query is as follows
mysql> select *from addWhereClauseDemo;
The following is the output
+-----------+-------------+-----------------+ | StudentId | StudentName | StudentPassword | +-----------+-------------+-----------------+ | 1 | John | John123456 | | 2 | Carol | 99999 | | 3 | Bob | OO7Bob | | 4 | Maxwell | Maxwell44444 | +-----------+-------------+-----------------+ 4 rows in set (0.00 sec)
