建立function時
出錯資訊:
ERROR 1418 (HY000): This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable)
原因:
這是我們開啟了bin-log, 我們就必須指定我們的函數是否是 1 DETERMINISTIC 不確定的 2 NO SQL 沒有SQl語句,當然也不會修改資料 3 READS SQL DATA 只是讀取資料,當然也不會修改資料 4 MODIFIES SQL DATA 要修改資料 5 CONTAINS SQL 包含了SQL語句
其中在function裡面,只有 DETERMINISTIC, NO SQL 和 READS SQL DATA 被支援。如果我們開啟了 bin-log, 我們就必須為我們的function指定一個參數。
解決方案:
-
