Oracle SQL Tutorial 30 - UTF-8 and UTF-16 Character Sets
 
04:01
A few videos ago we discussed UTF-8 and UTF-16 encoding, but when we are working with a database we do not worry about encodings as much as we do character sets. That's because a specific character set is going to have a specific encoding. The reason I am making this video is to introduce you to the most common character sets and to teach you the differences. That’s because as we go into the national character sets we need to understand the information taught in this video. So the first character set I am going to teach you about is AL32UTF8. AL32UTF8 is a character set that uses the uff-8 encoding and each character can take up to 4 bytes with the utf-8 encoding. There is another character set (not encoding) called utf8 (no hyphen) which is also encoded with UTF-8. This can be a little confusing because UTF8 is the name of an encoding and a character set, but bear with me. Both of these character sets are UTF-8 encoded, but UTF8 uses an older version of UTF-8 encoding. Generally, they work about the same, but the way certain characters are stored is slightly different, specifically way certain characters are stored is slightly different, specifically what are known as supplementary characters, which take up 4 bytes. The max size for a UTF8 character set is 3 bytes, as they do not directly support the supplementary characters as 4 bytes but instead store them across 2 groups of 3 bytes each. Oracle recommends that you use AL32UTF8 for all future development instead of the archaic UTF8 character set. There is another character set that you should know about, and that is AL16UTF16, which uses the UTF-16 encoding. Watch my video over UTF-8 and UTF-16 to learn more about UTF-16. Lastly, there is a character set known as UTFE, which uses an encoding known as UTF-EBCDIC. This is like a super archaic character set, and I'm not even going to talk about it. I thought I would at least mention it as it is going to come up a bit in the next video's topic. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 31 - NCHAR Part 2
 
03:12
This video is going to be part 2 of NCHAR. That's because I have a bit more things to say about it before we move on to other data types. The first thing I wanted to mention is that if you declare an NCHAR(50), it is going to always be 50 characters. You do not need to use the CHAR or BYTE keyword in parenthesis to specify which you would like. We've said that NCHAR uses Unicode, but as we've learned in the last video, there are many character sets that use Unicode. Which character set is NCHAR going to use? That decision is based off of what your database's national character set is. So for every database you can declare a database character set and you can declare a national character set. The national character set is what is used for this data type. There are two options for the national character set, AL16UTF16, and UTF8. The default is AL16UTF16, which uses the utf-16 encoding. The Oracle docs has a lot of pros and cons for each one, but in general the defaults are default for a reason, so AL16UTF16 usually works fine. Now, a few videos ago I made a comment about the CHAR and NCHAR data types and how they might not be recommended. Why so? The reason is that CHAR is secretly just a VARCHAR2 that is padded to take up a full length. It does not save space nor improve performance in the database, so the chances are you are never going to want to use it. That being said, everything you've learned has not been a waste because a lot can be applied to the VARCHAR2 and NVARCHAR2 data types. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

This is simple requirement. You might think to use OLE DB Source and then use Flat file destination. But there is small problem. The definition of Stored Procedure can change anytime, that means the number of columns returned by Stored Procedure can change. You need to develop an SSIS Package in such a way that you don't have to reopen and remap the columns every-time the definition of Stored Procedure change. link to script used in the video http://www.techbrothersit.com/2016/04/how-to-create-text-or-csv-file_7.html Check out http://www.techbrothersit.com/ for free Technology Tutorials /Interview Questions SQL Server Integration Services(SSIS) Tutorial SQL Server Reporting Services (SSRS) Tutorial SQL Server / TSQL Tutorial SQL Server DBA Tutorial Team Foundation Server Microsoft Dynamics AX

SQL Server Data Compression

Have you heard of the data compression feature in Enterprise Editions of SQL Server 2008 and later? It promises great savings on storage space. But did you know it can also improve I/O performance and enhance SQL Server memory? It also has costs too, in particular, it costs additional CPU to compress data on the fly. But how much CPU is spent on data compression overhead? Is it too much to be worth your time? Or is it an acceptable cost for the big gains in storage space, I/O performance, and memory improvements? To find out all about this cool technology, join Kevin Kline (@kekline) and Melissa Connors (@melikanokaoi) for this case study webinar. They’ll show how data compression works, how to choose the tables and indexes to compress, and the positive and negative performance impact of implementing data compression. Attend this webinar to learn the important ways that data compression affects workloads.

MySQL 25 - CHAR Data Type
 
04:47
The first category of data types that we are going to cover in this MySQL series are the string data types, or character data types. There are two that I am going to talk about in this video, CHAR and VARCHAR. We'll start with CHAR. CHAR is a string data type where you specify how many characters are allowed in parenthesis after you declare the column as this type. For example, we can say CHAR(50) to allow up to 50 characters for each value in that column. The thing to know about CHAR though is that it is a fixed-length string. That means every single value inside of that column is actually going to be whatever you declare the length as. So if you say CHAR(50), every string is going to be 50 characters long. If, for example, you have a row that only uses 40 characters, MySQL will pad the right side of the string with spaces until it fills 50 characters. Now, the highest value you can put in here is 255. The 255 refers to characters. This means that you can have strings with up to 255 characters. How does the computer know how to store these characters? That has to deal with the character set and the encoding of the characters. By default, MySQL is going to use UTF-8. We are not going to discuss UTF-8 in detail for a while but essentially UTF-8 says that each character can take up to 3 bytes of storage. 255 comes from the max number you can count to using binary. So if we are keeping track of how many values are in this column in an 8 bit number, 255 is the highest. If you don't know what I'm talking about it, we'll worry about it later. You can actually make the column CHAR(0). In this situation, the only thing you could put in as a value for this column is an empty string (''). When retrieving variable length CHAR data from a database it may not look like the database pads the value. That's because MySQL actually strips spaces from the value when presented. If you want to keep all of the spaces that have been added when you retrieve the value, you can do that. Look up PAD_CHAR_TO_FULL_LENGTH online. In the next video we are going to discuss VARCHAR. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)
