Question

我想将信息从carti插入domeniu但我收到错误消息。

CREATE TRIGGER trigger_UpdateItemDetails ON carti
FOR INSERT AS
BEGIN

INSERT INTO 
domeniu
(
    cod_d,
    materia,
    result
)
SELECT 
    id
    domeniu
    nr_exemplare
FROM 
   carti
END

错误消息：＃1064 - 您的SQL语法出错;校验与您的MySQL服务器版本对应的手册语法使用附近＆＃39; ON结果FOR INSERT AS BEGIN INSERT INTO domeniu （＆＃39;第1行

Answer 1

问题是int min = 2; int max = 26; int count = 10; double inc = (max - min) / (double) (count - 1); int[] weeks = new int[count]; double init = min; for (int i = 0; i < count; i++) { weeks[i] = (int) Math.round(init); init += inc; } System.out.println(Arrays.toString(weeks));。它应[2, 5, 7, 10, 13, 15, 18, 21, 23, 26]。检查 MySQL Documentation是否有FOR INSERT AS语法。看起来你混淆了BEFORE INSERT AS语法。 CREATE TRIGGER是MSSQL语法。

Answer 2

您应该使用以下命名约定命名触发器：

(BEFORE | AFTER)_tableName_(INSERT| UPDATE | DELETE)

例如after_tableName_insert

请参阅以下教程以创建触发器。 http://www.mysqltutorial.org/mysql-trigger-implementation.aspx
