这个 SQL 语句可能是在 Microsoft SQL Server 中使用的,根据你提供的语句,它应该是可以正常执行的。但是,如果它给出了错误信息,可能是由于以下原因之一:
1. 数据库中没有 `B_DAM_WATER_LEVEL` 或 `setting_single_coordinate` 表,或者表名错误。
2. 表中没有与查询条件匹配的数据。
3. `B_DAM_WATER_LEVEL` 表中的 `UPLOAD_TIME` 列的格式不正确。
4. `setting_single_coordinate` 表中不存在 `set_type` 或 `sys_type` 列,或者列名有误。
5. SQL 语句的语法错误。
请检查以上情况并确定是否有误。如果错误仍然存在,请提供错误信息以便更好地解决问题。

你提交的 SQL 语句中使用了两个 FROM 子句,这是错误的。正确的写法是将子查询放到一个括号中,并为其指定一个别名,然后在该别名后面使用 INNER JOIN 子句。请尝试使用以下 SQL 语句:
```
SELECT *
FROM
(
SELECT SENSOR_ID, DAM_ID, LEFT(UPLOAD_TIME, 10) AS UPLOAD_TIME, WATER_TOP, WATER_LEVEL, HOLE_DEPTH, (HOLE_DEPTH - WATER_LEVEL) AS BURIED_DEPTH
FROM B_DAM_WATER_LEVEL
WHERE ID IN (
SELECT MAX(ID)
FROM B_DAM_WATER_LEVEL
WHERE LEFT(UPLOAD_TIME, 10) = '2023-05-16'
AND SENSOR_ID = 1
GROUP BY LEFT(UPLOAD_TIME, 19)
)
) AS t1
INNER JOIN setting_single_coordinate ssc ON t1.DAM_ID = ssc.dam_id
WHERE ssc.set_type = 0
AND sys_type = 3;
```
SELECT ssc.dam_name, t1.SENSOR_ID, t1.DAM_ID, left(t1.UPLOAD_TIME,#{index3,jdbcType=INTEGER}) as UPLOAD_TIME, t1.WATER_TOP, t1.WATER_LEVEL, t1.HOLE_DEPTH, ( t1.HOLE_DEPTH - t1.WATER_LEVEL ) AS BURIED_DEPTH FROM ( SELECT SENSOR_ID, DAM_ID, left(UPLOAD_TIME,#{index3,jdbcType=INTEGER}) as UPLOAD_TIME, WATER_TOP, WATER_LEVEL, HOLE_DEPTH, ( HOLE_DEPTH - WATER_LEVEL ) AS BURIED_DEPTH FROM B_DAM_WATER_LEVEL WHERE ID IN ( SELECT MAX ( ID ) FROM B_DAM_WATER_LEVEL WHERE left(UPLOAD_TIME,#{index1,jdbcType=INTEGER}) = #{uploadTime,jdbcType=VARCHAR} and SENSOR_ID = #{sensorId,jdbcType=INTEGER} group by left(UPLOAD_TIME,#{index2,jdbcType=INTEGER})) ) ) AS t1 INNER JOIN setting_single_coordinate ssc ON t1.DAM_ID = ssc.dam_id WHERE ssc.set_type = 0 AND sys_type = 3; 索引下标7越界
根据你提供的SQL语句,我可以看到其中有三个参数:#{index1,jdbcType=INTEGER}、#{index2,jdbcType=INTEGER}和#{index3,jdbcType=INTEGER},而且这些参数都是整数类型。从错误信息来看,似乎是索引下标7越界了,这可能是因为你在执行SQL语句时传入的参数个数或者参数位置不正确导致的。
建议你检查一下你传入的参数是否与SQL语句中的参数一一对应,并且位置是否正确。如果还是无法解决问题,你可以将完整的错误信息和相关代码以及数据表结构等信息提供给开发人员进行调试。
