Insert query in SQL - INSERT INTO SQL

A Brief on the Insert Command in SQL

Once the table is created, the next step is to insert values into it according to its constraints. The insert statement consists of two ways.

  • Only values:

    Value of the data to be inserted is specified with the column names.

  • Column names and values:

    Column name is mentioned, and then the values are inserted.

We are using the only values method in this tutorial section. In only values, the values entered must be in an order according to the column.

Syntax

INSERT INTO tablename VALUES (value1, value2,….valueN);

where INSERT INTO and VALUES are the keywords and tablename is the name of the table; value1 to valueN are the set of values, followed by a semicolon.
Values are given for each of the columns, respectively. Whenever a variable length character appears, then the values are entered in a single quote. And when an integer appears, it is written just like that.

A Brief on the Insert Statement

  • After writing the query, click on the execute button to check for errors
  • Once the query is executed, a message appears like ‘Commands completed successfully’
  • Repeat the procedure and create 5 more sets of entries. Once you enter the records, the employee table will be displayed as follows:
e_id e_name e_salary e_age e_gender e_dept
1 sam 30000 26 male operation
2 julia 940000 27 female operation
3 anne 125000 21 female analytics
4 bob 50000 24 male support
5 jeff 20000 43 male sales
6 matt 940000 29 male operation

Finally, our table is ready with the values. We have inserted six records and, this is the way Insert query in SQL works. In the next tutorial section, we will learn how to select individual records from a table.
