REM Single line comment
-- Single line comment
/* Single line comment */
/*
Multi Line
comment
*/
补充:REM是REMARK的缩写
那么REM和--的区别是什么?
--或者/* */可以用于PL/SQL,但REM[ark]不可以。
下边这段可以在SQL*PLUS中执行成功
REM comment -- comment /* comment */ begin DBMS_OUTPUT.PUT_LINE(\'Test\'); --comment DBMS_OUTPUT.PUT_LINE(\'Test\'); /* comment */ end; /但下边这段就不行
begin DBMS_OUTPUT.PUT_LINE(\'Test\'); REM comment end; / begin REM comment DBMS_OUTPUT.PUT_LINE(\'Test\'); end; /

using the SQL*Plus REMARK command for single line comments.
using the SQL comment delimiters /*... */ for single or multi-line comments.
using ANSI/ISO (American National Standards Institute/International Standards Organization) comments - - for single line comments.
