Mysql中如何插入VarBinary二进制类型

把bina做一次编码，比如bin2hex

#include <math.h>
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
 
#define FirstDigit 48
 
void BinToHex(char* BinData, char* HexData)
{
   long int Number = 0;
   int BinLength = strlen(BinData);
 
   for(int i=0; i<BinLength; i++)
   {
      Number += ((BinData[BinLength - i - 1] - FirstDigit) * pow(2, i));
   }
 
   ltoa(Number, HexData, 16);
}
 
int main()
{
   char* BinBuffer = "11110101";
   char HexBuffer[256];
 
   BinToHex(BinBuffer, HexBuffer);
   printf("Bin: %s\nHex: %s", BinBuffer, HexBuffer);
   getch();
   return 0;
