sqlplus 执行脚本文件时如何传参数

Answer 1

d:\test.sql脚本如下:
[sql] view plaincopy
select &1 from &2;
exit;

执行时这样传猛余弯参数:sqlplus "scott/tiger@test" @d:\test.sql sysdate dual
注意:参数必须用&[1-9]表示,不然传不进去,会提示让手动输入参数
[sql] view plaincopy
C:\>sqlplus "scott/tiger@test" @d:\test.sql sysdate dual

D:\>sqlplus "scott/tiger@test" @d:\test.sql sysdate dual

如果脚本中有重复用到毁腔相同的值,如果&1=&2:
d:\tes2.sql
[sql] view plaincopy
delete scott.emp where no=&1 or deptno=&2;
commit;

执行时,就必须传2个参数:
[sql] view plaincopy
sqlplus "scott/tiger@test" @d:\test2.sql 10 10

小窍门: 这时用procedure就可以不用传多个相同的参数,则只用传1个参数:
d:\test3.sql
[sql] view plaincopy
declare
var_no number:=&1;
begin
delete scott.emp where no=var_no or deptno=var_no;
commit;
end;

sqlplus "scott/tiger@test"枝闷 @d:\test3.sql 10
