Question

有任何问题：

DELIMITER ;;
CREATE TRIGGER `UPD_after_financialStatus` AFTER UPDATE ON `financialStatus` 
FOR EACH ROW
BEGIN
DECLARE `@grossAmountTillNow` varchar(100);
SET @grossAmountTillNow = CONCAT(
    CAST(OLD.grossAmountTillNow AS varchar(50)),
    "---",
    CAST(NEW.grossAmountTillNow AS varchar(50)));
...

它说Syntax error near 'varchar(50)),"---",CAST(NEW.grossAmountTillNow AS varchar(50))); SET @grossAmoun' at line 4 你能帮忙吗？

请比较：

SELECT CAST(CURRENT_TIMESTAMP AS VARCHAR(50))

您的SQL语法有错误;检查与MySQL服务器版本对应的手册，以便在第1行“VARCHAR（50）”附近使用正确的语法

SELECT CAST(CURRENT_TIMESTAMP AS CHAR(50))

允许的值在Cast Functions and Operators解释。

语法错误@在表触发器中输出new.value
