What is the SQL syntax for creating a new table in MySQL?
The SQL syntax for creating a new table in MySQL is as follows:
1 2 3 4 5 6 |
CREATE TABLE table_name ( column1 datatype constraint, column2 datatype constraint, ... columnN datatype constraint ); |
Here, table_name
refers to the name of the table you want to create, and column1
, column2
, ..., columnN
are the names of the columns in the table. datatype
represents the type of data to be stored in each column, and constraint
refers to any additional conditions or rules you want to impose on the columns.
For example, let's say we want to create a table called employees
with columns for id
, name
, age
, and salary
. The SQL statement would look like this:
1 2 3 4 5 6 |
CREATE TABLE employees ( id INT PRIMARY KEY, name VARCHAR(50) NOT NULL, age INT, salary DECIMAL(10,2) ); |
In this example, id
is the primary key column, name
is a non-null varchar column limited to 50 characters, age
is an optional integer column, and salary
is a decimal column with a precision of 10 and a scale of 2.
