Can someone explain the syntax in the source attribute here? What the heck is "pack:" and "application:" and why 3 commas? I couldn't find any decent desciptions.
I am trying to do the following in a bit of python code:
class Parent:
class Child(Parent):
pass
And it does not work. Is there any python syntax I can use to achieve the same result?
Thanks.
Hi everyone
Iam trying to this in HQL:
select A.a A.a1, B.b,B.b1 from A,B
where A.x=B.x;
It is simple to realize the join with sql but when returninig in HQL I find a problem.
would you please give me the HQL syntax for the join
Thanks for help.
I know it's a basic question but I've tried every combination of propedit propset, etc.
In an existing project, there's a file (let's call it 'error.log) I want to ignore for all future commits. What's the command-line syntax to do so?
update p
set
p.storePrice =
CASE
WHEN
p.costPrice BETWEEN 0.00 AND 1.00
THEN p.costPrice * 1.0
CASE
WHEN
p.costPrice BETWEEN 0.00 AND 1.00
THEN p.costPrice * 1.0
ELSE
p.msrpPrice
END
FROM product p
WHERE p.type = 1
The error says:
Msg 156, Level 15, State 1, Line 9
Incorrect syntax near the keyword 'CASE'.
I can't seem to see any issue with the sql?
Reading the syntax from autohotkey, I am trying to achieve this. But the first step of selecting the entire line is not working:-
F5::
send {Shift Home}
return
I have tried few others too, but its not working. This is not sending Shift+Home combination on pressing F5 key.
Please tell me what's wrong with this?
Also if possible, what to do next?, as if I will write
send {F5}
I believe, it will recursively fire this script again and again..
Hi
I am using visual studios 2010 and created a javascript file(jscript.js) and I saw on one page saying you can make constant variables in javascript like:
const x = 20;
bu to on another page I read it says you can't. So I am confused now what is it now?
Also in Visual studios when I write "const" it underlines it in the javascript file and goes syntax error.
I've been looking into memory management a lot recently and have been looking at how events are managed, now, I'm seeing the explicit add/remove syntax for the event subscription.
I think it's pretty simple, add/remove just allows me to perform other logic when I subscribe and unsubscribe? Am I getting it, or is there more to it?
Also, while I'm here, any advice / best practices for cleaning up my event handles.
I always considered database as a storage .
but never thought it can be used for querying across tables etc.
Which is a good book for sql for a developer. not just the syntax.
How to write a query in different ways
How internally queries are executed.etc
especially related to microsoft sql server
The line cmd.ExecuteNonQuery();
cmd.CommandText
CREATE TRIGGER subscription_trig_0 ON subscription AFTER INSERT AS UPDATE user_data SET msg_count=msg_count+1 FROM user_data
JOIN INSERTED ON user_data.id = INSERTED.recipient;
The exception:
Incorrect syntax near the keyword 'TRIGGER'.
Then using VS 2010, connected to the very same file (a mdf file) i run the query above and i get a success message. WTF!
I'm have a number rows I'm inserting into a table using -insertRowsAtIndexPaths:withRowAnimation, and I would like the rows to be indented from the left to distinguish them from the rest of the cells. The indentationLevel property of UITableViewCell looks like it's exactly what I need, but it doesn't seem to do anything. Here's the code I'm using to set the indentation level (dot syntax doesn't make a difference):
[cell setIndentationWidth:10];
[cell setIndentationLevel:1];
Is indentationLevel what I want, or should I be looking elsewhere?

I was looking for a tool that can convert C code expressions for the form:
a = (A) ? B : C;
into the 'default' syntax with if/else statements:
if (A)
a = B
else
a = C
Does someone know a tool that's capable to do such a transformation?
I work with GCC 4.4.2 and create a preprocessed file with -E but do not want such structures in it.
When I read source from open source projects I often find a comment line with "$Id" at the header of the file, f. ex.:
// $Id: addappwindowa.c 30792 2009-03-07 22:40:04Z neil $
Is there an "offical" syntax for this lines? (What does "30792" means? )
Are there editors that auto-generate these "$Id"s?
Are there any tools that use this information?
Hello
I'm trying to do a request that looks like this
SELECT field1, field2, field3 = CASE
WHEN field2 = 'something' THEN 'something'
WHEN field1 IS NOT NULL and field2 IS NULL THEN 'somethingElse'
ELSE NULL
END
FROM SomeTable
WHERE field3 IS NOT NULL
This results in a syntax error. I have to rewrite the CASE in the WHERE instead of just refering to it. Is there a better way to achieve this ?
And out of curiosity, why is "WHERE field3 IS NOT NULL" refused while for example "ORDER BY field3" would pass ?

Hi
I know the spec allows both ' and " as delimiters for attribute values, and I also know it's a good practice to always quote.
However I consider " being the cleaner way, maybe it's just me having grown up with C and C++' syntax.
What is the cleanest way of quoting attribute values and why? Please no subjective answers.
I have this bash script where I am trying to change all *.txt files in a directory to their date of last modification. This is the script:
#!/bin/bash
# Renames the .txt files to the date modified
# FROM: foo.txt Created on: 2012-04-18 18:51:44
# TO: 20120418_185144.txt
for i in *.txt
do
mod_date=$(stat --format %y "$i"|awk '{print $1"_"$2}'|cut -f1 -d'.'|sed 's/[: -]//g')
mv "$i" "$mod_date".txt
done
The error I am getting is:
renamer.sh: 6: renamer.sh: Syntax error: word unexpected (expecting "do")
Any help would be greatly appreciated. Thank you for your time.
I'm relatively new to C, and am curious what this syntax means in a function declaration:
int DEFAULT_CC foo(void)
where DEFAULT_CC is probably defined somewhere else as:
#define DEFAULT_CC "cc"
Is this a direction to use a certain compiler or something?
I'd like to run git filter-branch on all children of a given commit. This doesn't seem to be an easy task, since there doesn't appear to be a way to tell git rev-list to only return children of a particular commit. Using the .. syntax won't work because it will also include the parent commits of any merge within that range. Am I missing something here?
I'm coming to C++ from a .Net background. Knowing how to use the Standard C++ Libraries, and all the syntax, I've never ventured further. Now I'm looking learning a bit more, such as what libraries are commonly used? I want to start getting into Threading but have no idea to start. Is there a library (similar to how .net has System.Threading) out there that will make it a bit easier? I'm specifically looking to do Linux based network programming.
Looking at the information under the heading "Precision can be omitted or be any of:".
The example: printf("%.*s", 3, "abcdef"); works, outputting:abc (truncating the rest of the string.)
Now, I would like to have a string with multiple parameters formatted (truncated):
printf("%.*s", "%.*s", 3, 3, "abcdef", "xyz123");
but the program crashes.
What is the correct syntax?
Thank You.
