Oracle PL/SQL历程调试的输出办法-PLSQL[Oracle防范]

declare

output varchar2(200);

begin

output:='...'; //赋值

DBMS_OUTPUT.PUT_LINE(output);

end;

(1) create table my_output{
id number(4),
txt varchar2(4000)  
);

(2) declare
output varchar2(4000);
strSql varchar2(4500);
count number(4):=0;
begin
strSql:='delete * from my_output';
EXECUTE IMMEDIATE strSql;

output:='...'; //赋值
count:=count+1;
strSql:='Insert into my_output value (count,'''||output||''')';
--''在单引号中相当于字符'
EXECUTE IMMEDIATE strSql;
end;

(1) create or replace directory TMP as 'd:\testtmp';

--成立一个文件夹途径

(2) declare

file_handle UTL_FILE.FILE_TYPE;

output varchar2(30000);

begin

output:="....";

file_handle := UTL_FILE.FOPEN('TMP', 'output.txt', 'w',[1-32767]);

--四个参数:目录,文件名,翻开方法,最大行数(默许为2000)

UTL_FILE.PUT_LINE(file_handle, output);

UTL_FILE.FCLOSE(file_handle);

exception

WHEN utl_file.invalid_path THEN

raise_application_error(-20000, 'ERROR: Invalid path for file or path not in INIT.ORA.');

end;
