我在SQL Server 2005中工作。我有一个存储过程，它创建临时表并从数据库表中提取数据。此临时表包含付款人类别的名称，余额/贷方，时间段（月份）和余额的“年龄”（当前，逾期30天，逾期60天等）。
我现在需要做的是按保险公司名称和年龄对这些数据进行分组/汇总。例如，Aetna的每条记录都减少到一条记录。那一条记录有一个当前余额的字段，一个超过到期余额30天的字段，一个超过到期余额60天的字段等.Aetna的每个当前余额应该在一个Aetna记录的第一个字段中求和。 Aetna的每30天到期余额应该在Aetna记录等的第二个字段中汇总，等等。结果表应该类似于：
Payor Class Cur 30 60 90 120 150
Aetna 1234.00 987.00 0.00 123.00 456.00 0.00
Blue Cross 3216.00 2100.00 321.00 0.00 212.00 401.00
Cigna 56123.00 30887.00 0.00 0.00 0.00 0.00
Kaiser 21003.00 1806.00 904.00 305.00 0.00 0.00
我当前的存储过程获取从应用程序（VB.NET）传入的开始日期，计算期间（即30天，什么是60天等），然后将所有余额记录拉入临时表。有一些预定的分组（医疗保险，医疗补助，私人），但任何不属于这些群体的东西都被分配给付款人类别（例如Aetna，Blue Cross等）。
我的问题是我提前不知道有多少不同的保险公司记录，所以我不确定如何根据这个和年龄分组/总结。如果我可以避免它，我宁愿不为每个循环做一个。任何帮助将不胜感激！

除非我遗漏了你的一些要求，否则以下情况应该这样做：
SELECT payor_class, SUM(balCurr), SUM(bal30), SUM(bal60), SUM(bal90), SUM(bal120),
SUM(bal150), SUM(bal180), SUM(bal210), SUM(bal240), SUM(bal270)
FROM Temp
GROUP BY payor_class
ORDER BY payor_class
如果payor_class不是保险公司名称，而只是一些代码，那么我可以将INNER JOIN添加到具有全名的表中。
