There is not non-binary values. What's 000101010101? A string "000101010101"?

According to the chart almost halfway down on this page[^], there is an implicit conversion between binary and almost all numeric types (except real and float).

If your binary value is in string (as SA asked), below code will help you:
int i = Convert.ToInt32("000101010101", 2); here 2 (second parameter) denotes the base of the first parameter (base for binary would be 2). For further help you can read the MSDN documentation for this method.

For Sql Server have a look at this link. This UDF works well when supplied digits only (in the input string) except the case when you want hexadecimal conversion, so take care of that in your calling code.

Hope that helps!
