I tried this but only got a syntax error:
<?php
$a = true;
$str = <<< EOF
{$a ? 1 : 2}
EOF;
echo $str;
Is it possible to use such kind of conditional statement inside heredoc?
I am working on a custom CRM form with numerous checkboxes, organized by sections. I would like to implement a 'select all' feature to the form and am trying to understand how to format the JavaScript. My research thus far has pointed me to the possibility of using a FOR statement to iterate through all of the elements in the section I want to process, setting their values accordingly, but am unsure of which document.getElements ... method to utilize.
Can we use Replace function in a update statement ?
If yes then How?
I have a column 'enrollno' having values like '800-00001' to '800-01800'.
I want to replace inital '800-' to '800' in all 1800 records.
(Output should be '8000001' to '80001800')
Is it possible through replace function or any other option is there in ORACLE8i ?

As I am a MySQL newbie. What does PARTITION mean in this MySQL statement?
CREATE TABLE employees (
id INT NOT NULL,
fname VARCHAR(30),
lname VARCHAR(30),
hired DATE NOT NULL DEFAULT '1970-01-01',
separated DATE NOT NULL DEFAULT '9999-12-31',
job_code INT NOT NULL,
store_id INT NOT NULL
)
PARTITION BY RANGE (store_id) (
PARTITION p0 VALUES LESS THAN (6),
PARTITION p1 VALUES LESS THAN (11),
PARTITION p2 VALUES LESS THAN (16),
PARTITION p3 VALUES LESS THAN (21)
);
I am trying to figure out how to create an 'if' statement that uses a time value as a condition. For example:
if (time <= 10:00) {
score = 3;
} else if (time <= 20:00) {
score = 5;
} else {
score = 9;
}
I know that a string of "5:23" cannot be compared this way but I don't think I can just turn a string value like that directly into an integer. Any thoughts?
What is the difference between JOIN, Inner Join, Left Join and Outer Join.
Let me put you on what i know.
JOIN Statement is used to join two tables and fetch the result.
Experienced Java programmer trying to learn Python. I have an applicaiton on Google App Engine and want to move my admin Handlers to a separate file. So now I have main.py and admin.py. I've set up app.yaml to route traffic properly, and have added the call to WSGIApplication() in each file to route to the appropriate Handler.
My question is does each script file need def main() and the corresponding if statement:
application = webapp.WSGIApplication([(r'/admin/(.*)', Admin)],
debug=True)
def main():
run_wsgi_app(application)
if __name__ == '__main__':
main()
Assume I have the following:
unsigned int *start;
unsigned int total;
#define OFF_MASK (1 << 31)
#define ON_MASK (~(1 << 31))
if (!(*start & OFF_MASK) && ((*start & ON_MASK) >= total)))
How do I change the above if statement so that it makes just one comparison like this:
if (*start >= total)
I tried to put an if statement inside an echo but this parse error came up, is it not possible to do that? should I use heredoc instead?
echo "<input name='main_branch' type='radio' value='1' <?php if($restaurant['main_branch'] == 1) { echo "checked"; } ?> />Yes
<input name='main_branch' type='radio' value='0' <?php if($restaurant['main_branch'] == 0) { echo " checked"; } ?> />No";
This is a statement referring to problem caused by page fault:(from Silberschatz 7th ed P-310 last para)
'We cant simply restart instructions when instruction modifies several different location
Ex:when a instruction moves 256 bytes from source to dest and either src or dest straddles on page boundary , then,after a partial move, if a page fault occurs, 'we can't simply restart the instructions'
My question is Why not?
Simply restart the instruction again do the same copy after page is in.
Is there any problem in it?
Class.forName("org.sqlite.JDBC");
Connection conn =
DriverManager.getConnection("jdbc:sqlite:userdata.db");
Statement stat = conn.createStatement();
ResultSet rs = stat.executeQuery("SELECT * from table WHERE is_query_processed = 0;");
How can I find out if rs is empty?
I am using OleDB for executing my queries in C#,
Is there any way I can execute multiple queries in one command statement?
I tried to separate them with semi-colon (;) but it gives error "Characters found at the end"
I have to execute a few hundreds of queries at once.
i'm trying to run a conditional statement in a class i'm placing in my App_Code folder
the condition is whether the person is logged in or not. I normally have two ways to do this in my masterpage and ASPX's
if (!User.IsAuthenticated) or if(Profile.username = "anonymous")
however neither of these things seem available to me in the .cs i'm making. anyone know what i'm missing? maybe a using namespace up top?
What was the most stupid code mistake you have ever made that had great consequences, e.g. you were fired?
For example, a friend of mine wrote a cycle with conditional statement for break that was never true, which caused one high-loaded site to hang up for the whole night.
In C# I could easily write the following:
string stringValue = string.IsNullOrEmpty( otherString ) ? defaultString : otherString;
Is there a quick way of doing the same thing in Python or am I stuck with an 'if' statement?
When i run a mysql select statement, it takes very long because i have already previously deleted a very large number of rows.
Is there a way for the table to start scanning from the bottom, as opposed to from the top?
This is a newbie configuration problem I suspect.
See return statement comment in code snippet.
[HttpGet]
public ActionResult TestService()
{
ViewBag.Message = "DataLayer Service";
Service dataLayerService = new Service {CookieContainer = new CookieContainer()};
dataLayerService.SetSessionAppName("SAND");
WebServiceModel webServiceModel = new WebServiceModel();
webServiceModel.Result = dataLayerService.GetSessionAppName();
return this.View(webServiceModel); // <== Cannot resolve View "TestService"
}
I have some code from a function
subl $24, %esp
movl 8(%ebp), %eax
cmpl 12(%ebp), %eax
Before the code is just the 'ENTER' command and afterwards there's an if statement to return 1 if ebp eax or 0 if it's less. I'm assuming cmpl means compare, but I can't tell what the concrete values are. Can anyone tell me what's happening?
Python needs a framework, so does Java (for the web). I don't know much about Ruby or Coldfusion. But is there another language out there for the web that can stand alone as it is without a need for a framework or without strict adherence to a design pattern (MVC and the likes) aside from PHP? BTW, the statement that Python and Java needs a framework to work with the web came purely from my readings on articles and books; I might be mistaken.
[root@jiaoyou ~]# test 1 = 1 -a 0 = 1
[root@jiaoyou ~]# if [1 = 1 -a 0 = 1]then echo 1;else echo 2;fi
-bash: syntax error near unexpected token `else'
Why test doesn't give any output and the if statement fails?
Can someone point out what's wrong here?
Consider the following Java source:
if( agents != null ) {
for( Iterator iter = agents.keySet().iterator(); iter.hasNext(); ) {
// Code that uses iter.next() ...
//
}
}
The agents is a HashMap.
Why does the for statement sometimes throw a NullPointerException?
Thank you.
I thought I remembered reading somewhere that IE9 would not be supporting them, but now after searching I can't find any indication that this is true.
Is anyone aware of a definitive statement, either way, about whether Microsoft will be supporting conditional comments in IE9?
I recently created around 700 attributes through script, all attributes look fine at backend.
But when I reindex, I get following error:
exception 'PDOException' with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'e.additional_information_s' in 'field list'' in /lib/Zend/Db/Statement/Pdo.php:228
Note: this attribtue exist in Database (eav_attribtue) table.
I would highly appreciate suggestion.
Looking forward to heat from you geeks.
Thanks
