java - SQLITE_ERROR - SQL 错误或丢失数据库(接近 "AUTOINCREMENT": syntax error)

Question

我正在尝试在新创建的 SQLite 数据库中创建一个表。由于某种原因，我收到 SQLException:

try {
        logger.debug("Trying to create table powerperms_permissions if not exists");
        statement.execute("CREATE TABLE IF NOT EXISTS powerperms_permissions ( "
                + "id INT NOT NULL AUTOINCREMENT,"
                + "uuid VARCHAR ( 64 ) NOT NULL,"
                + "permission VARCHAR ( 64 ) NOT NULL,"
                + "world VARCHAR ( 32 ) NULL,"
                + "PRIMARY KEY ( id ) );");
    } catch (SQLException e) {
        logger.error("Couldn't create permissions table",e);
    }

抛出

[07:49:17 ERROR]: [PowerPerms] Couldn't create permissions table
java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (near "AUTOINCREMENT": syntax error)

为什么？

Answer 1

您可以使用AUTOINCREMENT keyword仅适用于INTEGER PRIMARY KEY，而非INT NOT NULL。
