Question

我尝试过在线查看，但仍然继续运行此问题

CREATE TABLE CANDYINVENTORY
(
     CANDY CHAR(40),
     SOLD INT
);

INSERT INTO CANDYINVENTORY (CANDY, SOLD)
VALUES('POLARICE', 1);

无法执行查询。

错误：数据库中已经有一个名为“ CANDYINVENTORY”的对象。

Answer 1

您已经在系统中创建的表现在只需执行插入查询

INSERT INTO CANDYINVENTORY
(CANDY, SOLD)
VALUES('POLARICE',1);

Answer 2

您不需要每次都运行create table查询。创建表后，只需执行插入。

尝试创建此数据库时，为什么总是收到此查询错误？
