MySQL is by far the most popular database management system for small- to medium-sized web projects. In this course, Bill Weinman provides clear, concise tutorials that guide you through creating and maintaining a MySQL database of your own. Bill explores the basic syntax, using SQL statements to create, insert, update, and delete data from your tables. He also covers creating a new database from scratch, as well as data types, transactions, subselects, views, and stored routines. Plus, learn about the multi-platform PHP PDO interface that will help you connect your database to web applications.

Topics include:
  • Writing queries
  • Creating and updating databases and tables
  • Using MySQL built-in functions
  • Sorting and filtering data
  • Updating tables with triggers
  • Working with subselects and views
  • Creating and using a stored function
Subjects:

Inserting rows

The insert into statement is used to add a row or rows to a table. We'll select the scratch database here for this lesson. And I'm going to start by creating a temporary table. I'll just call it test. And we'll give it a couple of columns here. A INT, b TEXT and c TEXT. And now we'll insert a row into the table. INSERT INTO. So, I'm typing all of these.

Statements and I'm going to execute them all at once. So we're going to insert into test values one this right here and then we'll use a select statement to view what's in the table. Which should be one row. Now when I press the go button it will create the table and insert a row into the table. And then display it with the select. And there is the row that we created. So the insert into statement resulted in a new row in the table. And that's this statement right here, the second one.

The values clause is used to list the data values for the new row. So it says values and then in parentheses here it has those values for the new row, One, this one right here, and there they are in the table. Now you don't need to specify all of the columns in your values clause. You may optionally list the columns you want to provide in your values data. So, I'm just going to replace these two lines. We'll leave the select statement there, and I'll insert another row.

And here I'm going to list a couple of columns, just the B column and the C column. And just give values for that for those columns that and over there. So, this is a different form of an insert statement where before we just had values and we listed all three columns. In this one we're specifying. Two columns before the keyword values b and c and just the values for those two columns. So when I press go we get null and that end over there.

So the A column which is the int column has a null because there's nothing specified for it. So notice the result for the a column. This is null. Null is a state it's not actually a value, it's different and it's distinct from zero or an empty string. Null is a special state that represents no value. We'll talk more about null later on in this chapter. There's one more form of the insert into statement that's worth knowing about. You can use the results of a select statement in place of the values clause.

So, for example, I can say insert into test, like this and I can list some columns, a, b and c. And instead of the values clause I can say select ID name and description from item. Like that. And so this will take all of the rows from item. And take the id, name and descriptions columns and it will insert them into the test table.

And then we'll leave that select there so we can see the results. And here we have four rows from the item table. In the scratch database and their id name and description columns are mapped into the a b and c columns in the test table and select star from test it shows those results. So the results of the select statement are being used as the value. For the insert into statement.

This is a valuable technique for storing temporary or persistent results from a query. The insert into statement is very simple. There are several forms that allow you to specify what columns to populate and even to add rows from the results of a query. I'm going to leave this test table alone for now and the next lesson I'll show you how to update rows.
