How to Update Rows in Oracle SQL

How to Update Rows in Oracle SQL 

Update Command

Update Command is used to update existing records or rows of a database table. Update Command is applied when some changes happens in records. Suppose in case of an employee if he changes his city ,then his record in database must be updated. Another example could be for annual increments in salaries of all the employees, we need update command.

The general syntax of Update Command is give below

Update table name set column name=new value;

Example

Suppose you want to change present city of employee named Adam to Chandigarh

Update employee set ecity=’Chandigarh’ where ename=’Adam’;

You can also use arithmetic operators in update, like increment the salary of all the employees by 100.

The update statement will be like this:

Update employee set salary=salary+100;

Next : Select From Where

How to Delete Rows in Oracle SQL

How to Delete Rows in Oracle SQL

How to delete rows or records from a table in SQL

Delete Command

Delete Command is used to delete records from a database table, we can delete any number of records at a time in a single Delete Command. Delete Command of SQL uses Delete keyword.

The general syntax of Delete Command is as given below

Delete table name [where condition];

Example

Delete employee;

This will delete all the records from employee table.

We can delete particular rows or records  of a table.

Delete employee where ename=’Smith’;

This will delete record of Smith only.

We can use multiple conditions in Delete Command.

Suppose we want to delete records of all that employees whose city is Chandigarh and name is Smith.

The SQL delete statement will be like this:

Delete employee where ename=’Smith’ and ecity=’Chandigarh’;

How to Insert Values into Table in Oracle Sql

How to Insert Values into Table in Oracle Sql

Insert command

The insert command is used to insert records or rows in database table. Insert command is very simple in SQL, Insert keyword is used for inserting data in the database tables. Insert command of SQL inserts one record or row at a time.

The general syntax of insert command is as given below:

Insert into table name values( value1,value2,…);

Example

Insert into employee values(‘E001’,’ADAM’, ‘SYDNEY’);

In response to the above insert command , sql will generate the  message “1 row(s) created”.

By this way you can insert as many records as you wish.
