set

问题 I would like to pass a set of values as a parameter to an Sql Statement (in vb.net). In my case: Users are allowed to upload a set of IDs, to check availability of an item. I would like to execute a statement that will return the items that match any of the IDs by doing something like the following: SELECT * FROM MyTable WHERE id IN ('123','456','789') But I cannot pass on the value ('123','456','789') as a parameter as it will be taken as an atomic value - a whole string, i.e., this will not

问题 I created 1D array which shows words and in which sentences they occur. After that I took the intersection to show which word occurs with which each of other remaining words in sentence: OccursTogether = cell(length(Out1)); for ii=1:length(Out1) for jj=ii+1:length(Out1) OccursTogether{ii,jj} = intersect(Out1{ii},Out1{jj}); end end celldisp(OccursTogether) the output of above code is as below: OccursTogether{1,1} = 4 11 14 OccursTogether{1,2} = 1 OccursTogether{1,3} = [] OccursTogether{1,4} =

问题 I want to do exactly what it was described in this question: (Copy Column Value from One table into Another Matching IDs), but in SQLite instead of MySQL. The solution provided: update t1, t2 set t1.value = t2.p_value where t1.id=t2.parent_id returns an error near ","... If I say update t1 set t1.value = t2.p_value where t1.id=t2.parent_id returns an error near "." I was not expecting the syntax of MySQL being so different from SQLite. 回答1: You could try UPDATE t1 SET t1.value = ( SELECT t2.p

问题 I made a gui and I have a code (thanks Amro) that shows me a gif file. I want to show this gif file in 'hAxes' till the gui is closed (show it with the other uicontrol). I have a folder that has 200 pictures (image1.jpg, image2.jpg... image200.jpg) and I perform some things about these images (in loading1 uicontrol). I try something like: hFigure = figure('units','pixels','position',[300 300 424 470],'menubar','none',... 'name','start processing','numbertitle','off','resize','off'); hAxes =

问题 I am looking for the most efficient way to represent small sets of integers in a given range (say 0-10) in Python. In this case, efficiency means fast construction (from an unsorted list), fast query (a couple of queries on each set), and reasonably fast construction of a sorted version (perhaps once per ten sets or so). A priori the candidates are using Python's builtin set type (fast query), using a sorted array (perhaps faster to constrct?), or using a bit-array (fast everything if I was

问题 I'm trying to define in Z3 the parthood relation (called C in the code below) between pairs of sets (defined using array). I wrote 3 asserts to define reflexivity, transitivity, and antisymmetry but Z3 returns "unknown" and I don't understand why. (define-sort Set () (Array Int Bool)) (declare-rel C (Set Set)) ; reflexivity (assert (forall ((X Set)) (C X X))) ; transitive (assert (forall ((X Set)(Y Set)(Z Set)) (=> (and (C X Y) (C Y Z)) (C X Z) ) )) ; antisymmetric (assert (forall ((X Set)(Y

问题 I wish to run random forest in parallel using caret package, and I wish to set the seeds for reproducible result as in Fully reproducible parallel models using caret. However, I don't understand line 9 in the following code taken from caret help: why do we sample 22 (plus the last model in line 12, 23) integer numbers (12 values for parameter k are evaluated)? For information, I wish to run 5-fold CV to evaluate 584 values for RF parameter 'mtry'. Any help is much appreciated. Thank you. ##

问题 I am trying to write a batch script that saves the result of a command in a variable. so I can use it later. For example I am tryin to run this on the script: sc queryex "Service" |find /i "pid" but I want to save this result in a variable. set PIDRS=sc queryex "Themes" |find /i "pid" ECHO "%PIDRS% Any Ideas? 回答1: for /f "tokens=* delims=" %%# in ('sc queryex "Themes" ^|find /i "pid"') do set "PIDRS=%%#" echo %PIDRS% This will set the entire line to PIDRS here's how to get only the pid: @echo
