Row

In SQL, a "row" refers to a record in a table. Each row in a table represents a set of related data, and every row in the table has the same structure.

For instance, in a table named "customers", a row may represent one customer, with columns containing information like ID, name, address, email, etc.

Here is a conceptual SQL table:

ID	NAME	ADDRESS	EMAIL
1	John	NY	john@example.com
2	Jane	LA	jane@example.com
3	Jim	Chicago	jim@example.com

Each of these line of data is referred to as a 'row' in the SQL table.

To select a row, you would use a SELECT statement. Here's an example of how you might select a row:

SELECT * 
FROM customers 
WHERE ID = 1;

This would output:

ID	Name	ADDRESS	Email
1	John	NY	john@example.com

The * in the statement refers to all columns. If you want to only select specific columns, you can replace * with the column name(s):

SELECT NAME, EMAIL
FROM customers 
WHERE ID = 1;

In this case, the output would be:

Name	Email
John	john@example.com
