Oracle DB中SQL Script注释的语法
- 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;
- /
11.2 documentation on all comment types 关于注释有很清楚的说明。
You can enter comments in a script in three ways:- 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.
