非常抱歉,我之前的脚本有一些错误。以下是修正后的 SQL 脚本:
```sql
SET @start_date = '2023-06-01 00:00:00';
SET @end_date = '2023-06-30 23:59:59';
SET @current_date = @start_date;
WHILE @current_date <= @end_date DO
SET @table_name = CONCAT('gps_', DATE_FORMAT(@current_date, '%Y%m%d%H'));
SET @index_name = CONCAT('idx_plate_', DATE_FORMAT(@current_date, '%Y%m%d%H'));
SET @sql_statement = CONCAT('ALTER TABLE `gps`.`', @table_name, '` ADD INDEX `', @index_name, '`(`plate`) USING BTREE;');
PREPARE stmt FROM @sql_statement;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET @current_date = DATE_ADD(@current_date, INTERVAL 1 HOUR);
END WHILE;
```
请注意,我添加了 `PREPARE`、`EXECUTE` 和 `DEALLOCATE PREPARE` 语句,以便动态执行生成的 SQL 语句。现在,您可以尝试运行此修正后的脚本,并为每个表执行 `ADD INDEX` 操作。
对于此脚本,确保在执行之前对其进行仔细检查,并在测试环境中先执行以确保安全性。
如果还有其他问题,请随时提问!
