我有这段代码:
CREATE TABLE works_on (
works_on_id INT PRIMARY KEY,
jobid INT,
branchid INT,
employeeid INT,
CONSTRAINT jobid FOREIGN KEY REFERENCES job(jobid),
CONSTRAINT branchid FOREIGN KEY REFERENCES brahc(branchid),
CONSTRAINT employeeid FOREIGN KEY REFERENCES employee(employeeid)
);
CREATE TABLE manages (
managerid INT,
works_on_id INT,
CONSTRAINT managerid FOREIGN KEY REFERENCES manager(id),
CONSTRAINT works_on_id FOREIGN KEY REFERENCES works_on(id)
)
我试图从表单插入db,但是我收到了这个错误:
致命错误:在布尔值中调用成员函数bind_param() 第17行的C:\ wamp64 \ www \ gdlwebcamp \ admin \ insertar-admin.php
我已经调查了,因为准备返回假(我想是这样),尝试改变思考并逐个尝试但是不起作用,我该如何解决?感谢。
