string-concatenation

Its late and I probably should sleep on this. Easy one I have 3 fields in a form which a user fills in. Once they click the create button these records are saved to the database. Simple. However I want the data from these three fields at the same time to be concatenated together, nothing fancy..and inserted to the database at the same time as the other records. This should reflect back to the user on the show page after they create. So I need an action to concatenate 3 db columns lets say column names are firstname, surname and DOB. table name PeopleDetails I have tried building the model

I have the next two tables: CREATE TABLE #SalesByStore ( Brand VARCHAR(10), StoreName VARCHAR(50), Sales DECIMAL(10,2) ) CREATE TABLE #SalesByBrand ( Brand VARCHAR(10), TotalSales DECIMAL(10,2) ) I am trying to build an HTML table body using recursive string concatenation, and I need to show the sales by store ordered by brand, and after each group of stores from a same brand show the sales subtotals for that brand, like this: I am doing it the following way: DECLARE @tableBody NVARCHAR(MAX), @lastBrand VARCHAR(10); SELECT @tableBody=''; SELECT @tableBody = @tableBody + CASE WHEN @lastBrand IS

This question already has an answer here: Making a string concatenation operator in R 5 answers What's the most straight forward way of overloading '+' for characters? I have defined '%+%' <- function(...) paste(...,sep="") : str <- "aa"%+%"bb"%+%"cc" #str="aabbcc" But I don't like the syntax. I think str <- "aa"+"bb"+"cc" would be nicer. (I am building long SQL queries to use with RODBC, the usual paste is not very handy in such situations. Any suggestions?) I think that using two arguments is better than the dots: '%+%' <- function(x,y) paste(x,y,sep="") "a"%+%"b"%+%"C" [1] "abC" If you

This question already has answers here : Closed 9 years ago . Possible Duplicate: How should I concatenate strings? There are several ways to concat strings in everyday tasks when performance is not important . result = a + ":" + b result = string.Concat(a, ":", c) result = string.Format("{0}:{1}", a, b); StringBuilder approach ... ? what do you prefer and why if efficiency doesn't matter but you want to keep the code most readable for your taste? It depends on the use. When you just want to concat two strings, using a + b is just much more readable than string.Format("{0}{1}", a, b) . However

If I have two char arrays like so: char one[200]; char two[200]; And I then want to make a third which concatenates these how could I do it? I have tried: char three[400]; strcpy(three, one); strcat(three, two); But this doesn't seem to work. It does if one and two are setup like this: char *one = "data"; char *two = "more data"; Anyone got any idea how to fix this? Thanks Martin Ingvar Kofoed Jensen If 'one' and 'two' does not contain a '\0' terminated string, then you can use this: memcpy(tree, one, 200); memcpy(&tree[200], two, 200); This will copy all chars from both one and two

Possible Duplicate: Should I use Java's String.format() if performance is important? I was wondering if is good to use String.format in Java apps instead of StringBuilder ... so, I just write a simple test, like this: public static void main(String[] args) { int i = 0; Long start = System.currentTimeMillis(); while (i < 10000) { String s = String.format("test %d", i); i++; } System.out.println(System.currentTimeMillis() - start); i = 0; start = System.currentTimeMillis(); while (i < 10000) { String s = new StringBuilder().append("test ").append(i).toString(); i++; } System.out.println(System
