SQL SERVER 2005中的自动增加VARCHAR数据类型列 [英] Auto Increasing VARCHAR data type column in SQL SERVER 2005

问题描述

您好，我想创建一个列，该列在插入其他列的数据时会自动增加.基于某些条件，此列的数据类型为varchar，格式如下:
BD/00001/99A
EX/00002/00B
PS/00003/00A
之间的数字每次插入新数据时，00001-00003将递增.其他帮助是基于条件的，通常不会改变.
任何帮助将不胜感激.

hi there,
i want to create a column that increments automatically when data for other columns are inserted. The data type for this column is varchar made of the following format based on some conditons
BD/00001/99A

the numbers between 00001-00003 will be incrementing each time a new data is inserted. others are conditions based, usually not changing.
