will be helpful for those in need I have a query which is working fine and returns -1: , this will work:
code :
select decode((select -1 from dual),-1,'no_doc','anything') from dual;
 select decode((SELECT -1 FROM (select SUM(column1), column2 
 from documents where column2 is NULL group by column2) aa
 where aa.column2_rid = rid and typ_doc in (4,2) and rownum = 
 1),-1,'no_doc','anything') from dual;

Does that help i am trying to take entered values from textboxes and convert them to strings, total the amount, and then set the innerHTML of a to that value. , You're Doing It Wrong
For starters.
code :
function addBills(){
    var 
        hundreds = parseInt($("#input100").innerHTML(),10)*100;
function addBills(){
   var hundreds = Number(document.getElementById('input100').value)*100
   ,   fifties = Number(document.getElementById('input50').value)*50
   ,   twenties = Number(document.getElementById('input20').value)*20
   ,   tens = Number(document.getElementById('input10').value)*10
   ,   fives = Number(document.getElementById('input5').value)*5
   ,   ones = Number(document.getElementById('input1').value)
   ,   regTotal = hundreds+fifties+twenties+tens+fives+ones
   ; //end local
   document.getElementById('totalCount').innerHTML=regTotal;
}

fixed the issue. Will look into that further I can think of two approaches.
The first is to use a bunch of nested replace() statements:
code :
select replace(replace(replace(col, '$', ''), '£', ''), 'n/a', '')
select cast(left(substring(col, patindex('%[0-9]%', col), 1000),
                 patindex('%[^0-9]%', substring(col, patindex('%[0-9]%', col), 1000)) - 1
                ) as int)

To fix the issue you can do You can identify this error (overflow) in your error-handling block using the Description property of the intrinsic Err object:
code :
100:
MsgBox "Failed to convert """ & v1 & """ to an integer." & vbCrLf & Err.Description, , "Aborting - Failed Conversion" 
End
Dim tempArray As Variant
Dim arraySize As Double
arraySize = (Len(v1) - 1)
ReDim tempArray(arraySize)
Sub foo()
Dim lrg As New cLarge

MsgBox lrg.LargeAdd("105501008962100001", "205501231962100003")
End Sub

this one helps. Your main problem is that you define a variable on the stack, locally in the function, and then return it.
After the function returns, the char* will point to "somewhere", to an undefined position. That is a major bug. You have also other bugs that have been commented on already. Like sprintf(szHex, "0x%s", szHex);, which is undefined behaviour (UB) or sprintf(szHex, "%s%s", hex[nTemp], szHex); which has the same problem + additionally a wrong format string.
code :
#include <iostream>
#include <string>
#include <iomanip>
#include <sstream>

std::string toHexString(unsigned int hexValue)
{
    std::ostringstream oss;
    oss << "0x" << std::hex << hexValue;
    return std::string(oss.str());
}

int main()
{
    std::cout << toHexString(15) << '\n';
    // or directly
    std::cout << "0x" << std::hex << 15 << '\n';

    return 0;
}
#include <stdio.h>
#include <iostream>

char* toHexCharP(unsigned int hexValue, char *outBuffer, const size_t maxSizeOutBuffer)
{
    snprintf(outBuffer,maxSizeOutBuffer-1,"0x%X",hexValue);
    return outBuffer;    
}

constexpr size_t MaxBufSize = 100U;

int main()
{
    char buf[MaxBufSize];
    std::cout << toHexCharP(15, buf, MaxBufSize) << '\n';
    return 0;
}

it should still fix some issue If you use re.sub() to do the replacing, you can pass a function as the second argument rather than a plain string. The function will receive a match object based on what the regex matched. You can then use some thinking like itertools.count() (or your own object) to produce increasing numbers.
For example:
code :
import re
from itertools import count

button_number_count = 1;
htmlString = "this is sometext with more sometext and yet another sometext"

counter = count(button_number_count)

// replace sometext with sometext1, sometext2...
new_string = re.sub(r'sometext', lambda x: x.group(0) + str(next(counter)), htmlString )
'this is sometext1 with more sometext2 and yet another sometext3'
