Hello, I just switched over from c++ and I was wondering what the different data types in DBP were.

There are 8 basic types in all. Here is the list - DBPro on the left, and the C++ equivalent on the right.

integer - int
float - float
string - char*
byte - unsigned char
word - unsigned short
dword - unsigned int
double integer - long long
double float - double

Ah Thankyou

Thats reassuring because after reading some tutorials, I hadn't come across the "AS (DATATYPE)" form of declaring variables. I thought that just using a name creates an int, $ creates string, and # creates float. I thought only these three existed!

I always thought the reason that large projects compiled in c++ performed better than large projects in DBPro because DBPro only had 3 datatypes! Now, I know that is not the case so....

Why will large c++ projects perform better than large DBPro projects?

Could be that the tutorials you have been reading were DB Classic tutorials - which does only have those three variable types.

As you can see form IanM's post, DB Professional has a few more!

There are no DBPro equivalents to signed char, short, or long double. They don't seem to be missed by anyone.

BTW, are you talking DBC or DBPro?

I've been referring to DBPro. Does anyone know why large projects in c++ have better performance than in DBPro? No-one has answered yet
