The used select statements have a different number of columns. It’s the way we type the statements that makes them unique.
The code is more than just a series of statements you type, it’s also a series of statements you have to actually read. If you want, you can actually type out the entire statements and have them be displayed on the screen. The code that we see on screen is simply what’s displayed on the screen to the user.
The last two columns are the numbers that mark the number of the selected statements. They are just a few numbers. The numbers are in the middle of the statements, and the number of statements is the one that you have to type out. In our case, the numbers are in the middle of the statement, and the number of statements is the number of the statements you have to type out. So a simple use of the statements on the screen to the user and your computer is pretty clear.
Some people think that the number of columns is important, but I find that to be a bit of a misdirection. When I type “12” into the number box, the number of columns is just there as a visual cue to tell me that there are 12 columns available.
It makes it easier for me to type the statements out.
When I type a word in the statement box, I don’t have to type the number of clauses as I do with the select statement. It’s a much clearer way of expressing what I am trying to say.
Like us, you’re probably wondering about the difference between a select statement and a select list. Think of a select statement as a list that you put together in your mind. You then type whatever you want in the select statement box, and the computer just fills in the lines for you. It puts the words in different places.
A select statement is similar to the list. You put the words in different places, but it doesn’t start until you reach the end. You then type the number of clauses, and the computer does it for you. So the select statement is like the list except you put the words in different places and it keeps going until you reach the end, so it’s like a list of multiple select statements.
Select statements can be used to create multiple clauses. There are a few different things you can do with them. For example, you could say, “I want to create a clause that if the value of a column is greater than 7, then I get the value and the column number for that row.” You could also say, “If the value of column B is greater than 10, then I get the value of column B and the column number for that row.
One way to create multiple statements is to use the select statement directly. Another is to use the join statement. I’ve seen both used on the same page in other documents, so I’ll explain both in the same paragraph.
