MySQL INSERT INTO Query
The INSERT INTO query in MySQL allows you to add new
records or rows to a table in a database. It is a fundamental operation when it
comes to populating a table with data. In this tutorial, we will guide you
through the syntax and usage of the INSERT INTO query in MySQL.
Syntax
The basic syntax for the INSERT INTO query is as
follows:
Here's a breakdown of the syntax elements:
Examples
Let's explore a few examples to understand how the INSERT
INTO query works.
Example 1: Inserting Values into All Columns
To insert values into all columns of a table, you can omit
the column names in the query. The values will be inserted in the order of the
columns defined in the table's structure.
INSERT INTO employees
VALUES (1, 'John Doe', 'Software Engineer', 5000.00);
In this example, the values 1, 'John Doe', 'Software
Engineer', and 5000.00 are inserted into the respective columns of the employees table.
Example 2: Inserting Values into
Specific Columns
If you want to insert values into specific columns, you need
to provide the column names in the query. The values will be inserted into the
corresponding columns in the specified order.
INSERT INTO
employees (employee_id, employee_name, job_title, salary)
VALUES (2,
'Jane Smith', 'Data Analyst', 4000.00);
In this example, the values 2, 'Jane Smith', 'Data Analyst',
and 4000.00 are inserted into the employee_id,
employee_name, job_title, and salary columns of the employees
table.
Example 3: Inserting Multiple Rows
at Once
You can also insert multiple rows of data in a single INSERT INTO query by providing
multiple sets of values.
INSERT INTO employees (employee_id, employee_name, job_title, salary)
VALUES (3, 'Mark Johnson', 'Marketing Manager', 5500.00),
(4, 'Emily Davis', 'Graphic
Designer', 3500.00),
Take the next step |
(5, 'Michael Brown', 'Sales
Executive', 4500.00);
In this
example, three rows of data are inserted into the employees table, each with its own set of values.
Conclusion
Congratulations! You now have a solid understanding of the INSERT INTO query in MySQL. You can
use this query to add new records to a table, whether you want to insert values
into all columns or specific columns. Keep in mind the correct syntax and the
order of the values when executing the INSERT
INTO query. Enjoy populating your MySQL tables with data!
MySQL INSERT INTO query is used to insert records into a database table. The INSERT INTO statement comes in two forms: the first form doesn't specify the column names where the data will be inserted and the second form specifies the column names. There are a few things to keep in mind when using the INSERT INTO statement:
First the order of the values in the INSERT INTO statement must match the order of the columns in the table. Second if you don't specify a column list you must enter data for all columns in the table (in the order they appear in the table). Third MySQL automatically adds a NOT NULL constraint to any column that doesn't allow NULL values. Finally remember to always include a semicolon at the end of your SQL statements!
The MySQL INSERT INTO statement is used to insert new rows of data into a MySQL table. The MySQL INSERT INTO statement is used to insert new rows of data into a MySQL table. The syntax for the MySQL INSERT INTO statement is as follows:
MySQL INSERT INTO query is used to insert records into a table in a database. The syntax for this query is:
INSERT INTO table_name (column1 column2 column3 ...) VALUES (value1 value2 value3 ...);
The table_name is the name of the table into which you want to insert records. The column names are the names of the columns in which you want to insert values. The values are the actual data that you want to insert into the columns.
MySQL INSERT INTO query is used to insert records into a MySQL table. The INSERT INTO statement is used to add new rows of data to a table in the database. The insert statement is written as follows:
INSERT INTO table_name (column1 column2 column3,...columnN)
VALUES (value1 value2 value3,...valueN);
The number of columns and values must be the same. If you are inserting data into a table with more columns than values you must specify which columns you want to insert data into. You can do this by listing the column names after the INSERT INTO clause like this:
INSERT INTO table_name (column1 column2 column3)
VALUES (value1 value2 value3);
