sql - 插入外键时出现语法错误

Question

我一直在尝试将数据插入我的表时出错。我试过:

insert into saferdb_dot_contacts (fax, email, "dot_num_id") 
values( 'nan', 'nan', 4);

ERROR: column "dot_num_id" of relation "saferdb_dot_contacts" >does not exist

我试过:

insert into saferdb_dot_contacts (fax, email, dot_num_id) 
values( 'nan', 'nan', 4);

ERROR: column "dot_num_id" of relation "saferdb_dot_contacts" >does not exist

我试图通过

访问该字段

SELECT dot_num_id FROM saferdb_dot_contacts;

但是得到了:

ERROR: column "dot_num_id" does not exist LINE 1: SELECT dot_num_id FROM >saferdb_dot_contacts;

我试过:

SELECT 'dot_num_id' FROM saferdb_dot_contacts;

这给了我一个标有“?column?”的列的奇怪输出？

如果有帮助，dot_num_id 与另一个表具有外键关系。

编辑:我也试过:

SELECT "dot_num_id" FROM saferdb_dot_contacts;

ERROR: column "dot_num_id" does not exist LINE 2: SELECT "dot_num_id" FROM saferdb_dot_contacts; ^ SQL state: 42703

您需要注意区分大小写并使用双引号。尝试:

insert into saferdb_dot_contacts (fax, email, "DOT_Num_id") 
values( 'nan', 'nan', 4);
