我正在以oracle形式10g使用TEXT_IO过程,并且在按下按钮时触发了此过程
我在oracle表单上有很多参数。我想在下面的代码中使用表单参数。
PROCEDURE GEN_EXCEL IS
IN_FILE TEXT_IO.FILE_TYPE;
VC_HEAD Varchar2(32000);
vc_file_path Varchar2(50) := 'C:\';
BEGIN
IN_FILE := TEXT_IO.FOPEN(vc_file_path||'Test'||'.CSV','W');
TEXT_IO.PUT_LINE(IN_FILE,'YOUR_TITLE'||chr(10));
VC_HEAD := 'header1,header2,header3,header4';
TEXT_IO.PUT_LINE(IN_FILE,VC_HEAD);
FOR C1 IN ( SELECT column1, column2, column3, column4
FROM Table_name)
LOOP
TEXT_IO.PUT_LINE(IN_FILE,C1.col1||','||C1.col2||','||C1.col3||','||C1.col4);
END LOOP;
TEXT_IO.FCLOSE(IN_FILE);
MESSAGE('Excel file has been created!');
MESSAGE('Excel file has been created!');
EXCEPTION
WHEN Others THEN
TEXT_IO.FCLOSE(IN_FILE);
MESSAGE('Error while writing file.');
MESSAGE('Error while writing file.');
END;
如何以oracle 10g形式实现此目标?
