Question

我正在尝试创建一个mysql函数。但它不起作用，以下是错误：

错误代码1064，SQL状态42000：您的SQL中有错误句法;查看与MySQL服务器版本对应的手册使用附近的正确语法 '=（CO，CO1，CO2，CO3，CO4，CO5，CO6，CO7，CO8，CO9，CO10，CO11，CO12，CO13，co14）;' 在第58行

我试图修复但没有结果。

Answer 1

你的函数声明说它返回VARCHAR。那条线应该是：

cpt=CONCAT(co,co1,co2,co3,co4,co5,co6,co7,co8,co9,co10,co11,co12,co13,co14);

或者如果你想要它们之间的分隔符：

cpt=CONCAT_WS(',', co,co1,co2,co3,co4,co5,co6,co7,co8,co9,co10,co11,co12,co13,co14);
