Question

以下是我创建代码的代码，如下所示。

 CREATE or REPLACE TRIGGER sms_trigger
    AFTER INSERT ON student
    FOR EACH ROW
    ENABLE
    DECLARE lclcmd CHAR(255);
    DECLARE res VARCHAR(255);
     BEGIN

      SET lclcmd = CONCAT("php C:/xampp/htdocs/sample/sms_send.php");
      SET res = sys_exec(lclcmd);

    END;

运行上述代码后，出现如下错误

of the following:     begin function pragma procedure subtype type <an 
identifier>    <a double-quoted delimited-identifier> current cursor delete

2) Error(4,11): PLS-00103: Encountered the symbol "LCLCMD" when expecting 
one of the following:     transaction <a SQL statement>

Answer 1

检查以下内容，请注意，您已在concat中添加了一个字符串..，concat函数是错误的。

请注意，您不必再使用一次声明，也不必添加,Case When DATEPART(MM,CT.TransactionDate) = DATEPART (MM,Dateadd(mm, -3, getdate())) and DATEPART(YY,CT.TransactionDate) = DATEPART (YY,Dateadd(mm, -3, getdate())) and ct.SalControlValueInBaseCurrency <> 0 Then ct.SalControlValueInBaseCurrency End AS [Month4+]，并且在分配值时必须放置SET。
