Insert VALUES('') cant accept variable

[jason chan]

Hi,

I have a table with ip and time stamp

I would like to update the database if (a = b)

int a = 2;
int b = 2;

if (a == b)
{ mysql_query(connect,"insert into ipstat values(('b'),1,now())on duplicate key update hits=hits+1");
}

I have a primary key in the table having ID's 1 and 2. The problem here is that in the values('b') section, it does not recognize it as 2 and hence does not update the time stamp. However,If i physically put a values('2') it recognizes i have a ID 2 in the table and updates the time stamp.

How can i allow it to read the variable b as 2 for my case?

Thanks in advance

Jason
