sql - Derby SQL插入

Question

我正在尝试在我的数据库中插入值
这是我尝试执行的语句:

insert into leverancier (id,naam,straat,nr,postcode,plaats,telefoon) 
    values (1,"stef","bosstraat",88,9240,"Zele",null);

我收到以下错误:

ERROR 42X04: Column 'stef' is either not in any table in the FROM list or appears within a join specification and is outside the scope of the join specification or appears in a HAVING clause and is not in the GROUP BY list. If this is a CREATE or ALTER TABLE  statement then 'stef' is not a column in the target table.

问题是什么？

Answer 1

要插入字符串，例如 "stef" ，不要使用双引号，而是使用单引号: 'stef' 。声明应该是这样的:

INSERT INTO leverancier 
  (id, naam, straat, nr, postcode, plaats, telefoon) 
VALUES 
  (1,'stef', 'bosstraat', 88, 9240, 'Zele', NULL);

您收到 Column 'stef' is either not in any table ... 的错误是因为表名和列名使用了双引号。因此，阅读 "stef" 时，解析器假定您指的是名为 stef 的列。
