不好意思,我已经有了“transdate”专栏,为什么它说不存在?
答案 0 :(得分:8)
您的专栏名为"TransDate"
而不是transdate
。您使用列引号的双引号创建了表格,这使得它们区分大小写,您必须使用双引号所有时间:
INSERT INTO dxtest_loadprofiletosale
(id, "TransDate", "IssueDate", "CustomerNum")
VALUES
(1, '2015-03-04','2015-01-01',01);
有关SQL标识符的更多详细信息,请参见手册:
http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS
一般情况下,从不使用双引号会更好 - 从长远来看,它会给您带来更少的麻烦。
