Question

你能指点我的错误吗？顺便说一下，有没有SQLite语法荧光笔？感谢。

    sqlite> .schema recordtypes
    CREATE TABLE recordtypes (record_id text primary key);
    sqlite> .schema headers
    CREATE TABLE headers (header_id text primary key);
    sqlite>                                
    sqlite> 
    sqlite> CREATE TABLE record_to_headers (id INTEGER, recordid TEXT, FOREIGN KEY(recordid) REFERENCES recordtypes(record_id), headerid TEXT, FOREIGN KEY(headerid) REFERENCES headers(header_id));
    Error: near "headerid": syntax error

Answer 1

我相信您需要定义所有字段然后将它们映射到外键，如下所示：

CREATE TABLE record_to_headers (id INTEGER, recordid TEXT, headerid TEXT, FOREIGN KEY(recordid) REFERENCES recordtypes(record_id), FOREIGN KEY(headerid) REFERENCES headers(header_id));

如果有效，请告诉我。

Answer 2

在列定义之后放置约束：

CREATE TABLE record_to_headers (
    id INTEGER,
    recordid TEXT,
    headerid TEXT,
    FOREIGN KEY(recordid) REFERENCES recordtypes(record_id),
    FOREIGN KEY(headerid) REFERENCES headers(header_id)
);

Sqlite语法错误，请告诉我它在哪里？
