Datatypes in MySQL: getInt for integer, what for text?

As question. We use getInt to retrieve integer types in an MySQL database and getString for varchar types and so forth.What should i use for the text datatype? There is no getText. getString too?
Second question, I have a table which needs to store paragraphs of text in a row. What should i use? Text or blob? Any special precautions i need to take when using blob? Any special steps to take or is it just like the others?
Lastly, I also have the following error, i googled it up already, but mainly the results says something about missing jar files.To be honest i dont get them at all. Can anyone please explain it to me? Thanks.

The various getters on resultset relate to the form that the data is to be used in the program, rather than the form it's stored on the database. getString is fine for text.
The choice between clobs and text is often moot, it depends on how big the entries are likely to get, CLOBs are more complicated to use, they are stored separately from the database record and are optimised for quite large blocks. I wouldn't go to CLOBs if I expected the paragraphs to be less than about 2K characters.

Beginning MySQL Tutorial
By W.J. Gilmore
April 03, 1999
Part 1: At First Glance
MySQL is most commonly entered through telnet. (A nice Telnet program, Easyterm, can be found at http://www.arachnoid.com) Once the telnet connection to the web server has been accomplished, a second command provides access to the MySQL server. The procedure to make these connection is as follows:
1. Connect to telnet. This involves the insertion of the given ISP username and password.
--------------------------------------------------------------------------------login: devshed
Password: ********
Last login: Wed Aug 12 09:49:14 from 195.103.124.222

You have new mail.
www24:mywww/devshed#
2. Connect to MySQL. This involves the insertion of the username and password given specifically for MySQL use. This information has probably been provided to you at your request to the ISP provider.
--------------------------------------------------------------------------------www24:mywww/devshed# mysql -u devshed -p--------------------------------------------------------------------------------
Syntax: mysql -h hostname -u username -p[password]
Or
mysql -h hostname -u username --password=password
The user will then be prompted for a password, as prompted by -p.
--------------------------------------------------------------------------------Enter password: *******--------------------------------------------------------------------------------
Assuming MySQL has been correctly installed and configured, the user will see output similiar to the following:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 49 to server version: 3.21.23-beta-log
Type 'help' for help.
mysql>
(Note: If an error message pertaining to "Access denied" is the result of connection attempts, you should consult the MySQL documentation included with the software, the MySQL mailing list found at http://www.mysql.com, as well as your ISP provider. These resources will aid greatly in resolving these problems.)
Once connected to the database, we are free to execute the various commands of the MySQL language. However before we are able to modify the database, we must first connect to it, via the command:
--------------------------------------------------------------------------------mysql> use devshed;
Result:
--------------------------------------------------------------------------------Database changed
Mysql>
You now are connected to the database. Note that the command was followed by a semi-colon (;). Almost all commands in MySQL are followed by a semi-colon.
At the disposition are a number of administrative commands. These commands can be viewed simply by typing help, \h or ? at the command line:
--------------------------------------------------------------------------------mysql> help
help (\h) Display this text
? (\h) Synonym for `help'
clear (\c) Clear command
connect (\r) Reconnect to the server. Optional arguments are db and host
edit (\e) Edit command with $EDITOR
exit (\) Exit mysql. Same as quit
go (\g) Send command to mysql server
print (\p) print current command
quit (\q) Quit mysql
rehash (\#) Rebuild completion hash
status (\s) Get status information from the server
use (\u) Use another database. Takes database name as argument
Connection id: 49 (Can be used with mysqladmin kill)
mysql>

Let's make this simple:
a) Your book seems to assume you're doing development remotely.
b) You are not doing development remotely.
c) Therefore, you shouldn't follow every step listed in your book (i.e. ignore the stuff about Telnet).
Assuming you installed mySQL in the standard location, you can use this batch file to start mySQL on your machine:
@echo on
cd c:\mysql\bin
mysqld
@echo off
cls
Use this batch file to shut down mySQL:
@echo on
cd c:\mysql\bin
mysqladmin shutdown
@echo off
cls
You can play around without a login or password in development. For a production environment, you're going to need to set up users and grant permissions.
Spend some time reading the mySQL documentation.

What Are My Data Options for Droid 2? What About Texts?

I'm looking over the available plans and I'm really confused.
I've had the same plan pretty much for the past 15 months but I started with a Blackberry. Now I have a Droid 2 and I REALLY need to find a way to shave off some money from this bill.
My bill is always $118 and change with never goes above $119.
I have 900 minutes, was gonna take it down to 450 but viewing my usage I have been around 431-445 the past 3 months. I also have $10 for texts which I hate, I thought there was a $5 text plan?
Insurance, yes, have to because I can't afford a landline and don't have a house to put it in anyway.
I tried to get out of my contract with Verizon when I first became really sick. They were having none of that. I have been sick since September 2010 (symptoms 3 years) and the doctors have been running tests to find out what's causing the problem.
The tricky part is I cannot work anymore, used up everything I had in savings, and even sold my car to have money to pay for medical bills. Now I'm stuck trying to get state health insurance and am without a place to live.
I don't have income from any source but a lot of debt.
I wish Verizon would work with me as even when I can't buy food, I make sure bills are paid because I need that phone on so I doctors can reach me.
I'm not sure how long I'll be unable to work and when I can not sure how long it will take to find work.
I asked them if they could take the Droid 2 back and let me have a regular phone with no data and they said "no, you'll have to pay full retail price for the phone". I believe that was over $500 (no mention of the $179.99 I paid for the broken Tours)
Now here is the back story which really **bleep** me off that they could have screwed me twice:
The only reason I have the Droid 2 is because when I upgraded after my 1st year with Verizon, I got a Blackberry Tour. That phone had so many problems I had to keep taking it in every month for a replacement. Verizon refused to exchange for a different Blackberry.
I even called RIM and they said they had "design" issues with the Tour and it's being taken off the market with the phone carriers, they said Verizon should be allowing you to get a replacement phone of same or lower cost (another Blackberry).
Well that never happened and I had to file an FCC complaint before corporate finally called to help me. I even told them the "NEW" Tour I paid for when I signed a new contract was refurbished because when I tried to send the info in for the rebate, I got an letter stating that particular phone already received it's rebate.
I should have stopped it right there, given them their used phone back and walked away but I'm thinking they are working with me and gave me the rebate ASAP, it will be OK.
WRONG!! 6 months into the contract with the **bleep**ty Tour not working and 6 replacements, they agree to give me another phone for $50. I said drop dead, no more money from me for your issue.
Then they said OK we'll give you a phone of the same value at no charge. So not knowing how the Bold was gonna work yet, I went with a Droid 2 as the Droid 1 had been out awhile and bugs worked out.
Now here is the real kicker in the whole story. After they mailed me the new Droid, I was online paying my bill and noticed Verizon re-set my contract start date from January 2010 to August 2010.
No one told me that and I couldn't get anyone to help fix that mess, they said you got a new phone, what else do you want?
What do you think happened about 2 months after I get the Droid 2?? Yes, Verizon changed the policy and replaced the Tours with the Blackberry Bold for no charge and no contract extension.
Had they told me that, I would have used my old Blackberry for 2 months and gotten the Bold and be closer to getting out of this stupid contract.
I don't know, they make it so hard for honest people who have hit hard times and dealt with bad phone after bad phone to just get a fair break.
I asked so what happens if I just want out of the contract and they said it would cost like $350. If I had $350 I wouldn't be typing this. I suppose I can fake my own death and get out of the contract that way. They make no concession for persons who become disabled and can no longer work. I don't know how long I'll be "disabled" or if I ever won't be "disabled" but I like to think things will get better.
Any ideads would be great. I did talk with someone at UCAN, they help people in CA get out of cell contracts when they have extrordinary circumstances and they gave me a number for a lady at Verizon.
I called that women for 4 months every single day, 4 times a day. She never answered her phone or called me back, ever!
So guess I work on becoming dead since that's my only option. I will never, ever, ever sign a cell contract as long as live, if I live.
I don't mean to sound like such a bitchy customer, I really feel I was screwed from the start of this contract and the screws keep coming!

Not sure why you posted this in the iPhone forum but sorry you're having such a difficult time. With that being said, unfortunately, VZW isn't obligated to assist you in difficult financial times although it would be great if they did. As far as you wanting to get into a non-smart phone to lessen your bill...you will have to look into alternative ways to obtain one if you want to avoid paying full retail. Do you have any friends with Verizon? Check and see if any of them have an old phone that they don't use. Lower your plan to less minutes and actively monitor your usage. Save non-essential personal calls until after 9:00 pm on weekdays if you're calling non-verizon customers. Even without a house phone it is not difficult to get by on a 450 min plan without going over your minutes. My mother did it for 5 years and never once went over her minutes nor did she have a landline phone to use. Text when possible to avoid using minutes. If you stay with the Droid then try to find texting apps or widgets that can help eliminate the need for a text plan. You can also check into services like Skype that can allow you to make free calls to other users...some of your friends may gladly subscribe to those services so that you can communicate and use less plan minutes. You should also talk to VZW to see what lower plan options you have.

What is the include for text variable?

Dear Friends
I am trying to add a customer exit for text variables.
I have done variable exits for things like fiscal period but not for customer exit TEXT variables.
I could not find any text variable code in the include ZXRSRU01 .
Please advise what should be the program name?
Is it found in a different include?
regards
Bass

Hi Bass,
Customer exit for text variables is also the same how we create customer exits for characterisitics variable. As per the clarity what i got from ur question.
I'll just explain a small program in customer exits which will act as a text variable.
Go to SE38 -->
Display the program ZXRSRU01 --> (This can be done only if you have added the enhancement of the system from CMOD)
Then add ur following case statement to the existing code.
After all the data declarations start ur main program
when 'YEAR_CUST'.
if i_step = 2.
    l_year1 = sy-datum+2(2). //Data declaration
    l_mon1 = sy-datum+4(2). // Data Declaration
   l_date1 = sy-datum+6(2). // Data Declaration
     case l_mon1. //case statement which has the technical name of ur Exit variable
     when '01'. // This statement generally checks the whether the given variable entry has a value '01' then enters the statement here and returns the value as JAN //
          CONCATENATE 'JAN' l_year1 into dat.
          l_s_range-low = dat.
          l_s_range-high = l_s_range-low.
          l_s_range-sign = 'I'.
          l_s_range-opt = 'EQ'.
          APPEND l_s_range TO e_t_range.
          endcase.
         ENDIF.
Hope this helps u and have given the explanation as per the understanding of your questionand can give more clarity to you.

How to prepare MySQL DB for my VDI 3.1 POC

Dear all,
I am not really knows about database. My office asked me to setup and do a simple POC based on Sun VDI 3.1.
I have executed vda-install command and its installed, VDI core, mysql, SRS and others.
Next action is "Prepare your MySQL database" and this step is before running vda-config.
Appreciate if anyone could guide me on how to perform a simple MySQL setup for me to use for my POC on VDI 3.1.
Thanks in advance.

Hi Ali_Sampras ,
1. For a POC you might want to go for Evaluation [ option 0 ].
2. Execute ./vda-install ,reboot your server .
Once the server is up , execute ./vda-config and select option 0
You will have an evaluation setup up and running.
3.
-> You can use option 1/2 for a production setup ,high availability/fail over purpose i.e if you have 3 or more servers.
-> option 3 when you have license to use InnodB engine and have only one server.[here before executing ./vda-config you need to install/configure Innodb on the VDI host] .
-> option 0 when you have a single server and don't require fail over .
HTH ,

Is there an installer for mysql 5 for 10.5 PPC?

Is there an installer for mysql 5 for 10.5 PPC? I must be missing something because I can only find it for intel.

You are not missing anything. The mysql site only lists a version for 10.5 (Intel). Your best bet is to [contact mysql|http://www.mysql.com/about/contact> with your query (try using the contact us online link for immediate gratification).

Can a ComboBox be used for Text Input ?

Hi
In Ms Access the combo box can be used for text input for creating new lines in the Database instead of just being limited to the lines already there in the drop down list. Is this possible with the combo box available in Flex 4. If it is I haven't being successful in getting it to work.
Thanks for you help in advance

Ideas for text based budget management and software

I'm looking for suggestions for text-based software or just basic scripts for tracking expenses.
For the last six months I've been recording my purchases in text files, one file for each month.
An entry looks like this:
01/01/2013,Schnucks,banana, groceries,1.00,cash
It works pretty well for recording info, no alternative system could be much faster than just adding a line to a text file.
Now that I've been recording data for about 6 months, I'm more interested in parsing through it to see what I'm spending in each month and in various categories. At the moment, I just run the files through grep and awk to get what I want. I'm contemplating writing a python program to let me filter and calculate totals and do whatever else comes to mind: importing credit card statements, generating graphs, etc. But at that point, I feel like I'm probably just re-inventing the wheel.
Does anybody want to share how they are handling a similar case?
I'm ok with changing my entry format, but I'm pretty attached to handling things as text files. I don't need anything more complex if it adds to the overhead of creating an entry.

Hey, I been doing something very similar!
Except it also will measure income, so I can know how much I have done/expend this month, week, etc.
I don't have it at hand atm, but I use : to separate the fields, and use slashes to escape it (like \:)
Yes, that is a DSV file.
I haven't dedicated time to work on it lately, but I was writing a perl script to do the calculations.
One idea I have is to create an additonal file for a list of expenses names, like this:
milk-z:Milk brand Z:milk
milk-y:Milk brand Y:milk
the first field is an unique code for the product, second field a description, and third field is a category.
That way I could see how much I have expend on milk, no matter the brand.
On the expenses file, an expense would be similar to this:
2012-12-20:expense:milk-z:5.0
The first field has the date, in the format YYYY-MM-DD; that order is important to be able to sort the file if is necessary
Second field has "expense"; it could be "income" if it was an income
Third field is the product code - if its something I don't buy regulary, I could be only a name (like "new led tv" or something), if is an income, the reason behind the income.
And fourth field is just the amount of money.
Oh, I think I'll dedicate some time to the project again

Don't see email accounts to change notifications and no notifications for TEXTS.

I have had carrier issued software release 10.2.1.2977 for awhile.
I noticed now that under Notifications --> Core Applications there is no mention of any of my email accounts.
(But I have no issue receiving or sending email via this Q10).
And although it seems that I can change notification for Text Messages, in practice there is no LED or Vibrate or Sound that happens when a text does arrive. (And again there is no issue receiving or sending texts via this Q10 BUT no notification of any type)
Any ideas to resolve these notification problems?
If not, I will be forced, albeit reluctantly to "starting fresh".
Having said that I am not sure the best and safest way to do this ie reinstall carrier OS and then restore what I have backed up using BB Link.
I would love to know of the easiest, safest way to do as I have described.
Thanks for your advice.
And yet as you can see I am able to make changes of NOTIFICATON for texts but whatever I choose I still don't get notification via LED or VIBRATION and for my email accounts which Ican't see LED and VIBRATE is working fine (but of course can't change them)!
I have had this official OS10 software for awhile...well before I noticed this problem.

Why can I no longer specify my preferred font for text which has a link attached to it?

I use TBird to send old school, professional looking business letters with logo image header and footers. Recently, I am unable to apply my preferred font to the website link part of my footer. This seems to have become an issue after one of the more recent upgrades of TBird. Its frustrating as I feel good graphic design requires uniformity in font style/type and size. This seems no longer possible. Now when I attach a hyperlink to my website address it changes my preferred font to something that looks like Arial and locks both font and size. It looks crappy.

''Kits47 [[#answer-701080|said]]''
<blockquote>
The only way I know its 12 pt. is that I copy into Word and check the font size there.
</blockquote>
Huge error number one, and probably cause of your problem in the first place.
<blockquote>
I would really like to see TBird use point size for fonts.
</blockquote>
Thunderbird uses HTML, HTML is expressed in pixels.
<blockquote>
In terms of not having Papyrus on you Linux box, I suppose that's you're choice.
</blockquote>
Licensing actually, not choice. The font is licensed and distributed by Microsoft. See http://www.microsoft.com/typography/fonts/font.aspx?FMID=1113 for a list of products your recipient can install to get the font.
<blockquote>
In my outgoing email subject line I always specify that my reply is best viewed in HTML, full screen.
</blockquote>
HTML is the default for almost all mail so that does appear to be overkill. Full screen. Personally I would be just as likely to not read mail that required full screen. Mail gets about half a screen here.
<blockquote>
Most systems will automatically substitute fonts for ones not on that system, at least in Apple and PC systems. </blockquote>
Papurus actually has a higher chance of being present on a Mac system than a windows one as Apple have distributed it with OSX since 2003.
<blockquote>
Anyway all of that is a little off topic. I wanted help with why TBird intermittently messes with font size and style when I cut and pasting email responses to people.
</blockquote>
As I said at the beginning. Do not use word. Word first converts to RTF then to HTML (All done internally) The resulting HTML is extremely complex and to put it bluntly pastes as a whole page from which Thunderbird must extract only the relevant parts. (inside the body tag) The end result is the program ends up confused about what goes where.
<blockquote>
And, if there is some reason why sometimes, again I stress sometimes, it will not let me use the font of my choice for text that has a hyperlink attached to it.
</blockquote>
If your pasting from Word the most obvious thing will be that the hyperlinked text will have it's own font tags another reason I suggest you use the program your in.
* If you want it on paper use a word processor. It is what they are designed for
* If you want it in email use the email program to actually write your mail.
* If you want to guarantee the look on delivery send PDF attachments.
