OrientDB - Insert Record

OrientDB is a NoSQL database that can store the documents and graph-oriented data. NoSQL database does not contain any table, so how can you insert data as a record. Here you can see the table data in the form of class, property, vertex, and edge meaning classes are like tables, and properties are like files in the tables.
We can define all these entities using schema in OrientDB. Property data can be inserted into a class. Insert command creates a new record in the database schema. Records can be schema-less or follow some specified rules.
The following statement is the basic syntax of the Insert Record command.
INSERT INTO [class:]<class>|cluster:<cluster>|index:<index> 
   [(<field>[,]*) VALUES (<expression>[,]*)[,]*]| 
   [SET <field> = <expression>|<sub-command>[,]*]| 
   [CONTENT {<JSON>}] 
   [RETURN <expression>]  
   [FROM <query>] 

Following are the details about the options in the above syntax.
SET − Defines each field along with the value.
CONTENT − Defines JSON data to set field values. This is optional.
RETURN − Defines the expression to return instead of number of records inserted. The most common use cases are −
@rid − Returns the Record ID of the new record.
@rid − Returns the Record ID of the new record.
@this − Returns the entire new record.
@this − Returns the entire new record.
FROM − Where you want to insert the record or a result set.
Let us consider a Customer table with the following fields and types.
You can create the Schema (table) by executing the following commands.
CREATE DATABASE PLOCAL:/opt/orientdb/databases/sales 
CREATE CLASS Customer 
CREATE PROPERTY Customer.id integer 
CREATE PROPERTY Customer.name String 
CREATE PROPERTY Customer.age integer
After executing all the commands, you will get the table name Customer with id, name, and age fields. You can check the table by executing select query into the Customer table.
OrientDB provides different ways to insert a record. Consider the following Customer table containing the sample records.
The following command is to insert the first record into the Customer table.
INSERT INTO Customer (id, name, age) VALUES (01,'satish', 25) 
If the above command is successfully executed, you will get the following output.
Inserted record 'Customer#11:0{id:1,name:satish,age:25} v1' in 0.069000 sec(s). 

The following command is to insert the second record into the Customer table.
INSERT INTO Customer SET id = 02, name = 'krishna', age = 26 
If the above command is successfully executed, you will get the following output.
Inserted record 'Customer#11:1{id:2,age:26,name:krishna} v1' in 0.005000 sec(s).

The following command is to insert the third record into the Customer table.
INSERT INTO Customer CONTENT {"id": "03", "name": "kiran", "age": "29"}
If the above command is successfully executed, you will get the following output.
Inserted record 'Customer#11:2{id:3,name:kiran,age:29} v1' in 0.004000 sec(s).

The following command is to insert the next two records into the Customer table.
INSERT INTO Customer (id, name, age) VALUES (04,'javeed', 21), (05,'raja', 29) 
If the above command is successfully executed, you will get the following output.
Inserted record '[Customer#11:3{id:4,name:javeed,age:21} v1,
Customer#11:4{id:5,name:raja,age:29} v1]' in 0.007000 sec(s).

You can check if all these records are inserted or not by executing the following command.
SELECT FROM Customer
If the above command is successfully executed, you will get the following output.
----+-----+--------+----+-------+---- 
#   |@RID |@CLASS  |id  |name   |age  
----+-----+--------+----+-------+---- 
0   |#11:0|Customer|1   |satish |25   
1   |#11:1|Customer|2   |krishna|26   
2   |#11:2|Customer|3   |kiran  |29 
3   |#11:3|Customer|4   |javeed |21 
4   |#11:4|Customer|5   |raja   |29   
----+-----+--------+----+-------+----
