mysql-使用关键字作为列名时出现错误1064（42000）

Question

这怎么了 在Gentoo系统上成功运行了此操作，但现在在Debian-Squeeze（Raspberry PI）上无法运行。

数据库设置正确

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| arduino1           |
| mysql              |
| performance_schema |
| test               |
| tmp                |
+--------------------+
6 rows in set (0.01 sec)

mysql>

命令是：

#mysql -u root -p******* arduino1 < arduino-tables.sql

导致：

ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(8),
    currentTime DATETIME,
    timeDiff INT(10),
    unixTime INT(10),
    currentR1 FL' at line 3

arduino-tables.sql的内容：

#cat arduino-tables.sql:

CREATE TABLE pulseLog (
    id INT(10) UNSIGNED PRIMARY KEY NOT NULL AUTO_INCREMENT,
    timeStamp TIMESTAMP(8),
    currentTime DATETIME,
    timeDiff INT(10),
    unixTime INT(10),
    currentR1 FLOAT,
    currentS2 FLOAT,
    currentT3 FLOAT,
    currentAverageR1 FLOAT,
    currentAverageS2 FLOAT,
    currentAverageT3 FLOAT,
    temp0 FLOAT,
    temp1 FLOAT,
    temp2 FLOAT,
    temp3 FLOAT,
    temp4 FLOAT,
    temp5 FLOAT,
    pulses INT,
    event char(255),
 ) CHARACTER SET UTF8;

Answer 1

您使用的是datatype关键字。 您可以使用backtick示例将其转义

CREATE TABLE pulseLog (
    id INT(10) UNSIGNED PRIMARY KEY NOT NULL AUTO_INCREMENT,
    `timeStamp` TIMESTAMP(8),
    `currentTime` DATETIME,
    `timeDiff` INT(10),
    `unixTime` INT(10),
    currentR1 FLOAT,
    currentS2 FLOAT,
    currentT3 FLOAT,
    currentAverageR1 FLOAT,
    currentAverageS2 FLOAT,
    currentAverageT3 FLOAT,
    temp0 FLOAT,
    temp1 FLOAT,
    temp2 FLOAT,
    temp3 FLOAT,
    temp4 FLOAT,
    temp5 FLOAT,
    pulses INT,
    event char(255),
 ) CHARACTER SET UTF8;

Answer 2

在那里有一些拼写错误，例如timestamp是一个关键字，在event char(255),之后出现了一个逗号。

尝试这个：

    CREATE TABLE pulseLog (
    id INT(10) UNSIGNED PRIMARY KEY NOT NULL AUTO_INCREMENT,
    `timeStamp` TIMESTAMP,
    `currentTime` DATETIME,
    `timeDiff` INT(10),
    `unixTime` INT(10),
    `currentR1` FLOAT,
    `currentS2` FLOAT,
    `currentT3` FLOAT,
    `currentAverageR1` FLOAT,
    `currentAverageS2` FLOAT,
    `currentAverageT3` FLOAT,
    `temp0` FLOAT,
    `temp1` FLOAT,
    `temp2` FLOAT,
    `temp3` FLOAT,
    `temp4` FLOAT,
    `temp5` FLOAT,
    `pulses` INT,
    `event` char(255)
 ) CHARACTER SET UTF8;

这是SQL小提琴演示
