I tried to convert that SQL Query to Link but it does not work.
SELECT
SUM([Quantity]) as qt
,[ArticleID]
FROM [DB].[dbo].[Location]
Group by ArticleID
Order by qt
List <Location> articles = contexteEF.Location.GroupBy(l => l.ArticleID).Select(a => new { qt = a.Sum(b => b.Quantity), ArticleID = a.Key }).OrderByDescending(a => a.qt).ToList();
Can you help me! Please!
Thanks
You are trying to cast a list of dynamic objects to a List<Location>
I assume that Location has the properties qt and ArticleId? In that case, don't create dynamic objects, create Locations. Code not tested, but something like:
List <Location> articles = contexteEF.Location.GroupBy(l => l.ArticleID).Select(a => new Location() { qt = a.Sum(b => b.Quantity), ArticleID = a.Key }).OrderByDescending(a => a.qt).ToList();

I am having trouble creating a data frame with the following data:
Force (N) microstrain1 microstrain2 microstrain3 microstrain4 microstrain5
24.838 9.689 -20.299 19.785 15.601 -7.681
49.691 22.610 -40.797 41.304 32.200 -15.332
75.309 33.357 -61.678 62.512 48.726 -22.422
97.227 41.944 -80.524 81.011 62.266 -30.228
121.641 52.692 -100.775 100.703 77.248 -36.884
Every time I try to use a delimiter I get the following message:
/Users/macbookpro/PycharmProjects/Projects/Lab_3/Bending.py:5: ParserWarning: Falling back to the 'python' engine because the 'c' engine does not support regex separators (separators > 1 char and different from '\s+' are interpreted as regex); you can avoid this warning by specifying engine='python'.
df1 = pd.read_csv('MEE322-thurs_1040_group1_9.5cm.txt',delimiter=' ')
Did you try the python engine instead of the c engine?:
df1 = pd.read_csv('MEE322-thurs_1040_group1_9.5cm.txt', delimiter=' ', engine='python')

I am creating a medication ordering website as part on an assignment. I have a link table that contains the users id and medication id.
When a user is logged in I want them to see their medication only
SELECT [MedicineId] FROM [Prescription] WHERE ([PatientId] = #PatientId)
I have not created a log in yet because I dont want to log in every time im testing.
[![tables][2]][2]
You can use Session for a sample patient.
Session["PatientId"] = 1453;
var SqlQuery = "SELECT [MedicineId] FROM [Prescription] WHERE [PatientId] =" + Session["PatientId"].ToString();
With SQL Parameters
var SqlQuery = "SELECT [MedicineId] FROM [Prescription] WHERE [PatientId] = #PatientId";
var connection = new SqlConnection(/* your DB connection */);
var command = new SqlCommand(SqlQuery, connection);
command.Parameters.AddWithValue(
"PatientId", Session["PatientId"].ToString());

I'm looking for a Julia function which, when applied to a module name, lists the functions available through the module.
Basically, I don't want to scour through source code and I've noticed that the documentation for many modules usually doesn't have everything.
names works, mostly:
module MyMod
test() = 3
foo() = 4
end
names(MyMod, true)
gives me
4-element Array{Symbol,1}:
:eval
:test
:foo
:MyMod
Just need to strip out the module name and eval
Expanding on the previous answer slightly, the following seems to work:
function module_functions(modname)
list = Symbol[]
for nm in names(modname)
typeof(eval(nm)) == Function && push!(list,nm)
end
return list
end
Example:
using PyPlot
module_functions(PyPlot)
produces the following output in the REPL:
165-element Array{Symbol,1}:
:contourf
:over
:xticks
:ion
:flag
:summer
:stackplot
:tricontourf
:minorticks_on
:gray
:savefig
:errorbar
:box
:figure
:vlines
:subplot_tool
:jet
⋮
:locator_params
:imshow
:pie
:sci
:axhline
:streamplot
:hist2d
:copper
:text3D
:Axes3D
:loglog
:zticks
:hexbin
:pcolor
:semilogy

Here is my code:
- (CGFloat)layoutManager:(NSLayoutManager *)layoutManager lineSpacingAfterGlyphAtIndex: (NSUInteger)glyphIndex withProposedLineFragmentRect:(CGRect)rect
{
return 20;
}
def layoutManager(layoutManager, lineSpacingAfterGlyphAtIndex:glyphIndex withProposedLineFragmentRect:rect)
20
end
Start here: http://www.rubymotion.com/developer-center/guides/getting-started/
Should be something like this:
def layoutManager(layoutManager, lineSpacingAfterGlyphAtIndex: nil, withProposedLineFragmentRect: nil)
return 20.0
end
Check the repo for examples.
Also, that method should return a float, not an int.

}
if( $c[$p]['progressbar']['enable'] ) {
$c[$p]['side'] = draw_progressbar( reset( array_keys( $c[$p]['reasons']['data'] ) ), $all );
}
Whats Wrong Here ??
You have a closing bracket on line 1.
Assuming PHP this error means that reset() expects a variable and not the result of another function (like array_keys() in your example.
See the function signature: mixed reset ( array &$array )
This means that for your problem you need to store the array in a variable:
$tmp = array_keys( $c[$p]['reasons']['data'] );
$c[$p]['side'] = draw_progressbar( reset( $tmp ), $all );
