A basic mysql query structure:

mysql_query("...query here..");

A basic INSERT query:

mysql_query("INSERT INTO table_name (field1, field2) VALUES ('value1', 'value2') ");

We could again use the or die(mysql_error()) function to make it show the mysql error message when an error occurs.

So in the above example we made it insert a new row for the table ‘table_name’. For that row we gave field1 the value ‘value1′ and field2 the value ‘value2′.

Let’s have a look at an example of a table containing all user accounts (=rows):

Example table ‘users’:

[TABLE=1]

We already got one row in the table of the database, one user account. To add another one to this table we need to set values for the fields (id, )username, password, email. The ID field usually is auto_increment and primairy key, which means it’s a unique key for each row and automaticly increases for each new row that’s added and so doesn’t need to be set by ourselves. The example query would look like this ( for this table called ‘users’ ):

$new_user = mysql_query("INSERT INTO users (username, password, email) VALUES ('testuser', 'testpassword', 'test.email@hotmail.com') ");

You see we here create a new row using the INSERT query, for the table called ‘users’, giving the value ‘testuser’ to the field ‘username’, ‘testpassword’ to the field ‘passsword’ and ‘test.email@hotmail.com’ to the field ‘email’ for the new row we create ( representing a new user in this case ).

Hope you learnt something, if you have any questions, feel free to ask.
