由 ♀尐吖头ヾ 提交于 2019-12-10 08:52:00
问题 There's probably any easy solution for this, but I can't see it. I have a table with consecutive dates and often duplicate associated data for several of these consecutive dates: Date Col1 Col2 5/13/2010 1 A 5/14/2010 1 A 5/15/2010 2 B 5/16/2010 1 A 5/17/2010 1 A 5/18/2010 3 C 5/19/2010 3 C 5/20/2010 3 C Using MS T-SQL, I wish to find the start and end dates for each run of distinct Col1 and Col2 values: StartDate EndDate Col1 Col2 5/13/2010 5/14/2010 1 A 5/15/2010 5/15/2010 2 B 5/16/2010 5

问题 I'm trying to calculate percent off values for dollar amounts. At 50%, sometimes you get half a penny, and I need to round it to the nearest cent. In Sql, my calculation is as follows: round(retail * 0.5, 2, 0) If I take the following values I get different results: 4.39 2.49 Unrounded I get: 4.39 --> 2.195 2.49 --> 1.245 When rounded I get: 2.195 --> 2.19 1.245 --> 1.25 I'm told this is a form of "banker's rounding", but it seems like the value that is affecting the rounding direction is the

How to write a recursive query in SQL Server 2000

由 北城余情 提交于 2019-12-10 00:12:42
问题 I have a table which has a list which looks like this References R. Name LineNo. References A 1.1 (B,24.1) A 6.3 (A, 1.3), (D, 22.1) B 23.1 (A. 1.2) B 24.1 (B,23.1) C 2 (A, 1.1) D 3.12 (A, 6.3) The query should go one by one in the records and generate a value based on the references, pick first one lets say, which is Report Name A, Line No. 1.1, Now the reference is (B, 24.1), which means we need to find Report Name B, line no 24.1 and pick its value.

Unfortunately, I'm running PHP on a Linux server and using dblib to interface with Microsoft SQL Server, which doesn't support PDO::lastInsertID() . Please help! Update to include code example Here's the code I'm using: col1 is a

TSQL to know database role members

由 余生颓废 提交于 2019-12-08 18:09:04
问题 I am using SQL 2000 and SQL 2005. I want to know which logins have db_owner or db_accessadmin rights to which databases. I can click on users or database roles in every database to see that.

Thanks in advance 回答1: For SQL 2000 and still works for SQL 2005 too SELECT USER_NAME(memberuid), USER_NAME(groupuid) FROM sys.sysmembers WHERE USER_NAME(groupuid) IN ('db_owner', 'db_accessadmin') 回答2: It's sloppy and there is probably a better way, but

由 耗尽温柔 提交于 2019-12-08 13:41:35
I'm trying to add 0's to the beginning of an nchar(n) .

This won't work for numbers with more than n digits! Sorry for being slightly off-topic
