Hi I have a table of q-grams (2 letter strings). I need to join another table to this on the CHAR(2) field. Would it be faster to convert these 2-grams into a number (e.g. aa=1, ab=2, ac=3) and convert the fields in both this table and the referencing table to an INT and join using an INT rather? Kind regards Peter ...
Hello, I need to find a string in the source code (DDL) for all stored procedures in Oracle schema.

In a literal string (@"foo") in C#, backslashes aren't treated as escapes, so doing \" to get a double quote doesn't work. Is there any way to get a double quote in a literal string? (This understandably doesn't work: string foo = @"this \"word\" is escaped";) ...

I am learning about strings in C now. How come to use scanf to get a string you can do scanf("%s",str1); and for printf you can do printf("The string is %s\n", str1); I understand that for scanf it is because the string is just a character array which is a pointer, but for printf, how is it that you can just put the variable name...

I am trying to write server that will communicate with any standard client that can make socket connections (e.g. telnet client) It started out as an echo server, which of course did not need to worry about network byte ordering. I am familiar with ntohs, ntohl, htons, htonl functions. These would be great by themselves if I were trans...
I am building a language, a toy language. The syntax \#0061 is supposed to convert the given Unicode to an character: String temp = yytext().subtring(2); Then after that try to append '\u' to the string, I noticed that generated an error. I also tried to "\\" + "u" + temp; this way does not do any conversion. I am basically trying...
I am working on a project which requires working with XPath (on HTML). The (multiple) XPath is transferred to client-side inside JavaScript. Since XPath strings are long, I was wondering if there is a shorter representation which is equivalent to XPath? Perhaps one which works sort of like huffman encoding but specific to XPath. ...

Hello. Im stuck on writing Word occurrence in a string. I got some tip(in task notes) to use is compareToIgnoreCase. so I tried something like this: splitwords = StringCont.split("\\s"); for(int i=0; i<splitwords.length; i++) { if(splitwords[1].compareToIgnoreCase(splitwords[i]) == 0) splitcount++; } It is of course just w...
Hi all, I'm trying to find some code that, given a string, will allow me to iterate over each line using the for loop construct, but with the added requirement that separate for loop constructs will not reset the iteration back to the beginning. At the moment I have sList = [line for line in theString.split(os.linesep)] for line in SL...
