在 MySQL 中，`ALTER TABLE` 语句的 `ADD COLUMN` 语法不支持 `IF NOT EXISTS`，你需要修改你的语句。正确的方式是首先检查列是否存在，然后再进行添加。不过，你可以通过一个简单的方法在 MySQL 中动态执行这个检查，然后添加列。以下是修改后的语句：

-- 检查并添加 fuel 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `fuel` INT(10) DEFAULT \'100\';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'fuel');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 重复以上过程为每一列
-- engine
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `engine` INT(10) DEFAULT \'1000\';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'engine');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- ... 依此类推，为其他所有列执行相同的步骤 ...

-- 为了方便，这里可以将所有的列添加过程放在一个存储过程或批处理脚本中。

在 `CREATE TABLE` 语句中，`IF NOT EXISTS` 是可以使用的，你当前的 `CREATE TABLE` 语句是正确的。

整体思路是，MySQL 不支持在 `ADD COLUMN` 时检查列是否存在，因此需要先查询列的存在情况，然后再决定是否执行添加操作。

请根据以上示范手动为每个列检查并执行，如果有很多列的话，可以考虑写一个存储过程来自动化这个过程。

因为 MySQL 不支持在 `ALTER TABLE` 中使用 `IF NOT EXISTS` 语法，所以你需要将每个列的添加操作分开，并使用查询来检查列是否已经存在。你可以使用一个存储过程或一系列 SQL 语句来实现。以下是修改后的完整 SQL 语句示例：

-- 检查并添加 fuel 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `fuel` INT(10) DEFAULT ''100'';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'fuel');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 检查并添加 engine 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `engine` INT(10) DEFAULT ''1000'';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'engine');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 检查并添加 body 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `body` INT(10) DEFAULT ''1000'';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'body');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 检查并添加 damage 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `damage` LONGTEXT DEFAULT '''';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'damage');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 检查并添加 in_garage 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `in_garage` TINYINT(1) DEFAULT ''1'';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'in_garage');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 检查并添加 garage_id 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `garage_id` VARCHAR(255) DEFAULT ''Legion Square'';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'garage_id');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 检查并添加 job_vehicle 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `job_vehicle` TINYINT(1) DEFAULT ''0'';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'job_vehicle');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 检查并添加 job_vehicle_rank 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `job_vehicle_rank` INT(10) DEFAULT ''0'';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'job_vehicle_rank');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 检查并添加 gang_vehicle 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `gang_vehicle` TINYINT(1) DEFAULT ''0'';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'gang_vehicle');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 检查并添加 gang_vehicle_rank 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `gang_vehicle_rank` INT(10) DEFAULT ''0'';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'gang_vehicle_rank');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 检查并添加 impound 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `impound` INT(10) DEFAULT ''0'';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'impound');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 检查并添加 impound_retrievable 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `impound_retrievable` INT(10) DEFAULT ''0'';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'impound_retrievable');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 检查并添加 impound_data 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `impound_data` LONGTEXT DEFAULT '''';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'impound_data');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- 检查并添加 nickname 列
SET @sql = (SELECT IF(
    COUNT(*) = 0,
    'ALTER TABLE `owned_vehicles` ADD COLUMN `nickname` VARCHAR(255) DEFAULT '''';',
    'SELECT ''Column exists'';'
) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'nickname');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

请你逐个执行这些语句，确保所有新列都能正确添加。上述代码片段通过动态构建 SQL 语句来检查列的存在性，并相应地执行 `ALTER TABLE` 来添加列。

在 MySQL 中，`ALTER TABLE` 的语法不允许在 `ADD COLUMN` 中使用 `IF NOT EXISTS`。要将该行改为正确，你可以执行以下 SQL 语句来检查列是否存在后再进行添加。由于无法直接在单行中实现，下面是你需要的 SQL 语句：

SET @sql = (
    SELECT IF(
      COUNT(*) = 0,
      'ALTER TABLE `owned_vehicles` ADD COLUMN `damage` LONGTEXT DEFAULT '''';',
      'SELECT ''Column exists'';'
    )
    FROM INFORMATION_SCHEMA.COLUMNS
    WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'damage'
);

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

这个语句会先检查 `owned_vehicles` 表中是否存在名为 `damage` 的列，如果不存在则执行添加该列的操作。如果列已存在，则不会做任何动作。你可以将其放入你的脚本中以实现正确的操作。

在 MySQL 中，`ALTER TABLE` 的 `ADD COLUMN` 语句确实不支持 `IF NOT EXISTS`。你需要手动检查列是否存在后再进行添加。

你可以使用以下 SQL 语句来替代原来的 `ALTER TABLE` 语句。以下是一个检查并添加列的示例：

SET @sql = (
    SELECT IF(
      COUNT(*) = 0,
      'ALTER TABLE `owned_vehicles` ADD COLUMN `fuel` INT(10) DEFAULT 100;',
      'SELECT ''Column exists'';'
    )
    FROM INFORMATION_SCHEMA.COLUMNS
    WHERE TABLE_NAME = 'owned_vehicles' AND COLUMN_NAME = 'fuel'
);

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

你可以用类似的方式将其他的列添加到 `owned_vehicles` 表中。这里的步骤是先检查列是否存在，如果不存在则执行添加操作。这样就可以避免出现 SQL 语法错误。

重复这个过程为其他列（如 `engine`、`damage` 等），确保所有列都能被正确添加。

在 MySQL 中，`BLOB`、`TEXT`、`GEOMETRY` 和 `JSON` 类型的列是不允许设置默认值的。所以你在创建 `damage` 列时不能使用 `DEFAULT ''`。

你可以直接去掉默认值，像这样：

ALTER TABLE `owned_vehicles` ADD COLUMN `damage` LONGTEXT;

如果你想为现有行的 `damage` 列设置一个特定的值，可以在添加列后使用 `UPDATE` 语句来进行调整，示例如下：

-- 创建列
ALTER TABLE `owned_vehicles` ADD COLUMN `damage` LONGTEXT;

-- 选则性地更新已有数据
UPDATE `owned_vehicles` SET `damage` = '' WHERE `damage` IS NULL;-- 仅对于 NULL 值

这样，你就能成功添加列而不会遇到默认值的问题。请更新你的 SQL 语句。
