SQL TYPE MAP such as SQL_CHAR, SQL_NUMERIC , etc

Hello,

May I know where I can find some online documents about mapping the
integer values to the following SQL types please?

For example, if I have value 1 , so that I know 1 is mapped to SQL_CHAR;
if I have value 3, so that I know 3 is mapped to SQL_NUMERIC.

Thanks a lot,
Emi
