我无法判断我的特定情况是否已经涵盖了其他问题的标题，如果答案已经存在，那么道歉。
我有一个数据库，它将值记录为字符串，另一个表记录了这些值中特定类型的运行。
我需要一个迭代值的存储过程（我理解这与游标的概念有关），将每个值记录到临时表以控制特定运行类型的计数（奇数/偶数，例如，或元音/辅音）。当给定值指示特定类型的运行已停止时（即奇数停止了偶数运行，反之亦然），运行计数，计数被插入到具有相关类型值的运行表中（0 = odd / even，1 =元音/辅音等），删除临时表内容，并将导致表计数/清除的值插入临时表。
由于我对存储过程完全不熟悉，我不知道如何构建这种过程，我发现的例子不是：
如果有任何需要澄清，请告诉我。
编辑：
正在使用的版本：MS SQL Server 2012
原始值的表结构：
ID: Int PK AI
DateTimeStamp: Datetime
SelectedValue: Char(2)
UserId: Int
值运行的表结构：
ID: Int PK AI
DateTimeStamp: Datetime
Type: Int
Run: Int
示例数据：[以下以逗号分隔的字符串显示，为简洁起见，由一位用户输入]
e，00,1，t，r，2,4,3,5,7，a，i，w，q，u，o，23,25,24,36,12，e ... < / p>
组将是：
vowels/consonants
even numbers/odd numbers
00
numbers under/over 20
numbers/letters
从上面来看，运行是：
e (vowels/consonants: vowels)
e (numbers/letters: letters)
00 (00)
1 (odd/even: odd)
1 (numbers/letters: numbers)
t, r (vowels/consonants: consonants)
t, r (numbers/letters: letters)
2, 4 (odd/even: even)
3, 5, 7 (odd/even: odd)
2, 4, 3, 5, 7 (numbers/letters: numbers)
a, i (vowels/consonants: vowels)
w, q (vowels/consonants: consonants)
a, i, w, q, u, o (numbers/letters: letters)
1, 2, 4, 3, 5, 7 (under/over 20: under 20)
23, 25 (odd/even: odd)
23, 25, 24, 36 (under/over 20: over 20)
24, 36, 12 (odd/even: even)
u, o, e (vowels/consonants: vowels)
这将使运行表的条目为
Type: vowels/consonants, run: 1
Type: numbers/letters, run: 1
Type: 00, run: 1
Type: odd/even, run: 1
Type: numbers/letters, run: 1
Type: odd/even, run: 2
Type: odd/even, run: 3
Type: numbers/letters, run: 5
Type: vowels/consonants, run: 2
Type: vowels/consonants, run: 2
Type: numbers/letters, run: 6
Type: under/over 20, run: 6
Type: odd/even, run: 2
Type: under/over 20, run: 4
Type: odd/even, run: 3
Type: vowels/consonants, run: 3

如果您对查询有效感到满意，可以将最终的SELECT替换为INSERT INTO Runs (ID, Type, Run) SELECT ID, Type, Run FROM cteFinalRuns，以便一次性填充表格。
