错误编号:3780;符号:ER_FK_INCOMPATIBLE_COLUMNS; SQLSTATE: HY000
消息:错误代码:3780。在外键约束“eval_fact_table_ibfk_3”中引用列“Geography_ID”和引用列“Geography_ID”不兼容。
最佳答案
错误 Referencing column 'Geography_ID' and referenced column 'Geography_ID' in foreign key constraint 'eval_fact_table_ibfk_3' are incompatible.
很清楚,列不兼容:
CREATE TABLE IF NOT EXISTS Geography_Dim (
Geography_ID varchar(25) not null,
CREATE TABLE Eval_Fact_Table(
... truncated
Geography_ID int(11) not null,
使它们具有相同的类型或删除外键约束。
您可以阅读有关外键约束的更多信息 in documentation ,最有趣的部分是
Corresponding columns in the foreign key and the referenced key must have similar data types.
您的情况并非如此:
varchar(25)
对比 int(11)
