问题
I'm new to SAS and I'm using the PROC SQL functionality. I can not understand which is the sql language used in the PROC SQL.
It seems similar to Oracle-Sql but some functions are not available.
Can anyone clarify this point?
回答1:
PROC SQL supports the ANSI SQL definition from 1992. You can also use most SAS functions.
International Organization for Standardization (ISO): Database SQL. Document ISO/IEC 9075:1992. Also, as American National Standards Institute (ANSI) Document ANSI X3.135-1992
