How do I merge multiple (3+) columns into one, where there are blank or #N/A cells involved? I can use the Two-Into-One article just fine for handling blanks (or changing isblank to isna to handle #N/A values), but I haven't been able to get it to handle 3+ columns even after trying to combine the parsing of both articles together. Lines 97-98 set rngSrc, the column of data from our Source Worksheet. Since we know the column number (lngIdx, as we’re looping through the columns) as well as the last-occupied row on the Source Worksheet (lngLastSrcRowNum), we can create this Range using these cells.

You don't have to retrieve all the information from a table. You can retrieve only the information you want from the columns you want and filter out the rest.

SQL Used

Retrieving a single column:

Retrieving multiple columns:

Examples:

See all of the SQL used in SQL Basics in the SQL Basics Cheat Sheet.

In the previous video we used the selectstar from table query to retrieve all 0:00

information in a table, but you may notwant to bring back all the information. 0:05

Often you want a smallsubset of information. 0:10

This can be particularly helpful ifyou don't want to bring back sensitive 0:13

Like the addresses or dates of birth. 0:18

Let's take a look at some simpleways to retrieve only some 0:21

Let's start with all the informationfrom the patrons table. 0:26

The asterisk, or star, is short hand forall of the column named in the table. 0:34

Now, what if I wanted to retrieve onlythe emails from our patrons table? 0:39

We still want to select somethingfrom our patrons table. 0:44

All we need to do is change the asterisk,remember? 0:50

We can replace it withthe column name we want. 0:57

As you can see this selects allthe emails from our patrons table. 1:05

What if we wanted all the firstnames in our patrons table. 1:12

You just to write the name of the firstname column first underscore name 1:17

Okay, let's change that back. 1:27

Having either all columns or a singlecolumn returned back has limited utility. 1:33

Remember, the power of SQL is that youcan retrieve any subset of information 1:38

from a table without beingdestructive to the underlying data. 1:43

Nothing is deleted,it's just presented differently. 1:47

Let's say I wanted to send out a librarynewsletter talking about the new book 1:52

How do I go about retrievingboth the first name and 1:58

In other words, 2:02

how do I select two columns of datafrom the database with one query? 2:03

SQL makes this kind oftask pretty easy on us. 2:08

each column I want witha comma in the SQL query. 2:13

The great thing is that I can changethe ordering of the columns how I see fit. 2:19

Since the recap,the area between the SELECT and 2:34

the FROM keywords is the columns youwant to get the information from. 2:37

SELECT * FROM patrons is a lot shorterthan including all of the column names. 2:42

You're a better person than me if youcan remember all the column names. 2:46
