这是一个复杂的SELECT语句，它使用了多个表的JOIN和聚合函数来生成结果集。以下是对该语句的解释：

SELECT
	SUM( CASE WHEN A.RUNLONGTIME IS NULL THEN 0 ELSE TO_NUMBER( A.RUNLONGTIME ) END ) AS 运行时间,
	SUM( CASE WHEN A.TOTALTIME IS NULL THEN 0 ELSE 12 END ) AS 总时间,
	CONCAT( CONCAT( B.SUPUSER_ID, ':' ), B.SUPUSER_NAME ) AS 技术员,
	ROUND((
		SUM( CASE WHEN A.RUNLONGTIME IS NULL THEN 0 ELSE TO_NUMBER( A.RUNLONGTIME ) END ) / SUM( CASE WHEN A.TOTALTIME IS NULL THEN 0 ELSE 12 END )),
	4 
	) * 100 oee ,
	'2023-06-26 08:00:00' AS 开始时间,
	'2023-06-27 08:00:00' AS 结束时间,
	( CASE C.PROCESS WHEN '3' THEN '焊线A区' WHEN '5' THEN '焊线B区' WHEN '7' THEN '焊线C区' END ) AS 区域 
FROM
	RPT_EQP_STATETIME A
	LEFT JOIN BAS_USEREQP_CONFIG B ON A.EQP_ID = B.EQP_ID 
	AND A.CREATED_TIME = B.END_TIME 
	LEFT JOIN BAS_EQP_EQUIPMENT C ON A.EQP_ID = C.EQP_ID  
WHERE
	A.EQP_ID LIKE 'WB%' 
	AND A.CREATED_TIME > to_date( '2023-06-16 08:00:00', 'yyyy-MM-dd hh24:mi:ss' ) 
	AND A.CREATED_TIME <= to_date( '2023-06-26 20:00:00', 'yyyy-MM-dd hh24:mi:ss' ) 
	AND B.START_TIME >= TO_DATE( '2023-06-16 08:00:00', 'YYYY-MM-DD HH24:MI:SS' ) 
	AND B.END_TIME <= TO_DATE( '2023-06-26 20:00:00', 'YYYY-MM-DD HH24:MI:SS' ) 
	AND A.CREATED_TIME = B.END_TIME 
GROUP BY
 	B.SUPUSER_ID,
	B.SUPUSER_NAME,
	C.PROCESS 
ORDER BY
	OEE DESC

这个查询语句从表RPT_EQP_STATETIME(A)、BAS_USEREQP_CONFIG(B)和BAS_EQP_EQUIPMENT(C)中检索数据。它使用了LEFT JOIN关键字将这些表连接起来。

查询的目的是计算运行时间、总时间、技术员、OEE指数、开始时间、结束时间和区域。其中，运行时间和总时间是通过SUM函数和CASE表达式计算得出的。技术员是通过CONCAT函数将SUPUSER_ID和SUPUSER_NAME拼接而成的。OEE指数是通过运行时间除以总时间，并乘以100计算得出的。

查询还包括了一些筛选条件，例如EQP_ID的模糊匹配，CREATED_TIME的范围限制等。

最后，查询使用GROUP BY子句对SUPUSER_ID、SUPUSER_NAME和PROCESS进行分组，并使用ORDER BY子句按OEE指数降序排序结果集。
