Following is my code.I have used class in my website.But i am getting error as "Incorrect syntax near ',' ".....can anyone tell me what is wrong in the code..
protected void btnadd_Click(object sender, EventArgs e)
{
s1 = "Update tckt_tbl Set class='" + ddlclass.Text + "',dist=" + lbldist.Text + ",no_of_adults=" + ddladults.Text + ",no_of_senior=" + ddlsenior.Text + ",n1='" + txtn1.Text + "',";

s1 += "gen1='" + txtgen1.Text + "',gen2='" + txtgen2.Text + "',gen3='" + txtgen3.Text + "',gen4='" + txtgen4.Text + "',gen5='" + txtgen5.Text + "',gen6='" + txtgen6.Text + "',";

con.ExecQuery(s1);
Response.Redirect("tcktbook_itckt.aspx");
}
First off, it is a really bad idea to build a query from user input. I suggest you use a parameterized query instead.
Try outputting s1 to see what the query looks like.
Chances are good that you have an unbalanced quote.
On third line there is problem.
s1 += "ag1=" + txtag1.Text + ",ag2=" + txtag2.Text + ",ag3=" + txtag3.Text + ",ag4=" + txtag4.Text + ",ag5=" + txtag5.Text + ",ag6=" + txtag6.Text + ",";
I think here commas and semicoluns are not given properly.
I suggest you use Parameter Query, rather than concatenate everything. But before that, are you sure that you already give all value? Because if you didn't give any value for numeric field, it should show an error, since the query become:
..cag1=,cag2..

I am trying to add equations to my code which are quite long. When I do so, R does not quite grasp where the end of the equation is and when I go to the next line filled with whitespace, it puts the cursor to the middle of the line rather than the beginning, as usually.
When I run the code, it ignores the end of the long equation, as one can tell from the console output
+ # 3.b) Initialize ODEs
+ initialstate <- c(
Error: unexpected symbol in:
"# 3.b) Initialize ODEs

# 3.b) Initialize ODEs
initialstate <- c(*[...some other cade that work unless you add the long equation above...])*
Bizarrely, if I write more than one of these longer equations, it recognises the end of exactly every second one, i.e. it pairs two, which leads to the issue. For the ones that it does not pair, it also has the > rather than + in the respective place in the console. I could get it to work fine for 5 short equations.
As I am exporting the equations from Matlab (as I need to use the symbolics toolbox to find the solution), I checked whether any of
cutting whitespaces out online, incl. equation by equation, so line by line
pasting the many equations into Word to see whether there is a difference in the tabs/new lines etc. between the equations for which the pasting interrupts between equations appropriately versus not (no both are the same)
past into text editor before moving to R, incl. equation by equation, so line by line
using my local version of R studio rather than the R studio workbench I was using previously
would help but they did not.
I have tried for a long time now and would be super grateful for any insight!
R is built with a maximum line length of 4096 characters as shown in this thread. Lines that are longer than that will need to be broken.

For a particular small data set containing 7 items, I have created the following new array:
f.rhs <- c((-orig_qty + looped_data$TOTAL_EFFECT[1])/looped_data$MULTIPLE_ORDER_QTY[1],
(-orig_qty + looped_data$TOTAL_EFFECT[1] + looped_data$TOTAL_EFFECT[2])/looped_data$MULTIPLE_ORDER_QTY[1],
(-orig_qty + looped_data$TOTAL_EFFECT[1] + looped_data$TOTAL_EFFECT[2] + looped_data$TOTAL_EFFECT[3])/looped_data$MULTIPLE_ORDER_QTY[1],
(-orig_qty + looped_data$TOTAL_EFFECT[1] + looped_data$TOTAL_EFFECT[2] + looped_data$TOTAL_EFFECT[3]+ looped_data$TOTAL_EFFECT[4])/looped_data$MULTIPLE_ORDER_QTY[1],
(-orig_qty + looped_data$TOTAL_EFFECT[1] + looped_data$TOTAL_EFFECT[2] + looped_data$TOTAL_EFFECT[3]+ looped_data$TOTAL_EFFECT[4] + looped_data$TOTAL_EFFECT[5])/looped_data$MULTIPLE_ORDER_QTY[1],
(-orig_qty + looped_data$TOTAL_EFFECT[1] + looped_data$TOTAL_EFFECT[2] + looped_data$TOTAL_EFFECT[3]+ looped_data$TOTAL_EFFECT[4] + looped_data$TOTAL_EFFECT[5] +looped_data$TOTAL_EFFECT[6])/looped_data$MULTIPLE_ORDER_QTY[1],
(-orig_qty + looped_data$TOTAL_EFFECT[1] + looped_data$TOTAL_EFFECT[2] + looped_data$TOTAL_EFFECT[3]+ looped_data$TOTAL_EFFECT[4] + looped_data$TOTAL_EFFECT[5] +looped_data$TOTAL_EFFECT[6] + looped_data$TOTAL_EFFECT[7])/looped_data$MULTIPLE_ORDER_QTY[1])
As you can see, this code is very very ugly. Essentially what's happening is at each new value, we are taking the previous values and adding some new stuff to it from the next line of data(incremental calculations essentially).
How would I go about doing this same process and making this row for a dataset containing an arbitrary amount of observations?
Using cumsum() would help you. Something like this maybe:
f.rhs = (-orig_qty + cumsum(looped_data$TOTAL_EFFECT)) / looped_data$MULTIPLE_ORDER_QTY[1]
I need help simplifying the following to the simplest terms. Boolean algebra just doesn't quite click with me yet, any help is appreciated.
(!A!B!C)+(!AB!C)+(!ABC)+(A!B!C)+(A!BC)+(AB!C)
I got it to the following, but I don't know where to go from here:
!A(!B!C + B!C + BC) + A(!B!C + B(XOR)C)
If you are curious and want to check my previous work, I got the original equation from the truth table:
Initially we have A(~B~C + ~BC + ~CB) + ~A(~B~C + B~C + BC)
First Term: A(~B~C + ~BC + ~CB)
= A(~B(~C + C) + ~CB)
= A(~B(True) + ~CB)
= A(~B + ~CB)
= A((~B + ~C)(~B + B))
= A((~B + ~C)(True))
= A(~B + ~C)
Second Term: ~A(~B~C + B~C + BC)
= ~A(~C(~B + B) + BC)
= ~A(~C(True) + BC)
= ~A(~C + BC)
= ~A((~C + C) (~C + B))
= ~A((True) (~C + B))
= ~A(~C + B)
So First Term + Second Term becomes: ~A(~C + B) + A(~B + ~C)
= ~A~C + ~AB + A~B + A~C
= AxorB + ~A~C + A~C
= AxorB + ~C(~A + A)
= AxorB + ~C(True)
= AxorB + ~C
Hence we end up with AxorB + ~C
