这个 SQL 查询语句是一个复杂的查询,它从多个表中检索数据,并使用 LEFT JOIN 连接这些表。以下是对该查询的分析:
查询主要目的: 这个查询的目的是检索出满足一定日期范围条件的数据,并将结果返回。查询涉及到了几个表,包括 be_UserDoBatchRecord、ix_jnml01、ix_jnml02 等。
子查询 t1: 第一个子查询 (t1) 从 be_UserDoBatchRecord 表中选取数据。其中,使用 DATE_FORMAT 函数将 CreateDate 字段转换成指定格式的日期,并将结果作为 CreateDate 列的值。然后,使用 GROUP BY 按照 UserID、CreateDate 和 BatchState 进行分组,计算出每个分组的 InputDataCount(InputDataCount 的计算使用了 SUM 聚合函数)和 Qty(Qty 的计算也使用了 SUM 聚合函数)。
子查询 t2: 第二个子查询 (t2) 是一个 UNION ALL 的组合查询,从多个表中选取数据。每个子查询都使用了相同的日期范围条件,并计算每个日期与用户的匹配数 (InputDataCount),然后按照日期和用户 (IX_ZLRQ 和 IX_ZLR) 进行分组。
LEFT JOIN 连接: 最后,将子查询 t1 和 t2 使用 LEFT JOIN 连接,并通过 t1 的 CreateDate 和 UserID 与 t2 的 CreateDate 和 UserID 进行匹配。匹配成功的记录将包含在查询结果中,并返回包含 t1 和 t2 列的结果集。
