ET_BP_FACT我想通过许多值示例（25,50,75）更新表Intent intent = new Intent(Intent.ACTION_VIEW)
Uri outputFileUri = FileProvider.getUriForFile(getActivity(), BuildConfig.APPLICATION_ID + ".provider", file);
intent.setDataAndType(outputFileUri, "application/pdf");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Intent in = Intent.createChooser(intent, "Open File");
startActivity(in);
从Cursor返回但是当我执行由（25,25,25）更新的表时
我认为循环中存在问题
答案 0 :(得分：0)
那是因为UPDATE的{{1}}子句没有“引用”游标的值。像这样：
WHERE我建议你总是在列名前面加上表别名，因为 - 查看你的代码，没有办法猜测哪个表DECLARE
CURSOR contacts
IS
SELECT month_id, org_unit_id, --> include additional columns here ...
SUM (budget) AS budget
FROM et_bp_gl_account a, et_bp_fact f
WHERE f.gl_account_id = a.gl_account_id
AND total_flag = 0
GROUP BY month_id, org_unit_id;
BEGIN
FOR r IN contacts
LOOP
UPDATE et_bp_fact
SET budget = r.budget
WHERE gl_account_id IN
(SELECT total_element
FROM et_bp_gl_account g, et_bp_fact f
WHERE f.gl_account_id = g.gl_account_id
--
AND f.org_unit_id = r.org_unit_id --> ... and reference them here ...
AND g.month_id = r.month_id);
--> ... or, possibly, here
END LOOP;
END;
和{{1属于，所以我的代码可能（或可能不）工作，但我希望你有一般的想法。
