问题 I have databse having 2 tables i.e (Installment and InstallmentPlan). In the installment table there are number of columns. I want to add one new computed column name SurchargeCalculated (SC). The calculation for SC is this SC = (Installment.Amount * Installment.days * (InstallmentPlan.InstPercentage /365 /100)) I have created user-defined function SurchargeCal having 3 parameters which are Amount, days and InstPercentage. The problem is that when i add computed column in installment table

问题 ColdFusion 8 This is as simple pseudo-code as there can be: <cffunction name="badJSON" access="remote" output="true" returntype="string" returnformat="JSON"> <cfreturn "06762" /> </cffunction> Results in: 6762.0 It should result in: 06762 Is there a way to get JSON to not convert my value to numeric? I know I can use WDDX, but that is out of the question. 回答1: Have you tried this? return javaCast("string", "06762") 回答2: Ok, so there is no real way to do this in CF8. The workaround is to add a

问题 My issue is very similar to this issue. However, I'm using SQL Server 2005 Service Pack 2 (SP2) (v9.0.3042) and the solution posted there does not work for me. I tried using both connection strings. One is commented out in my code. I realize I can store all the results in a List or ArrayList in memory and return that. I've done that successfully, but that is not the goal here. The goal is to be able to stream the results as they are available. Is this possible using my version of SQL Server?

问题 I want to be able to use some global variables in my Workbook and in the ThisWorkbook Code I have declared the following varaibles Public position_1 as string Public position_2 as string If I want to see the value of those variables I believe the need to be fully qualified so Debug.Print ThisWorkbook.position_1 Debug.Print ThisWorkbook.position_2 I have written a UDF which I will pass in an integer to represent which variable I am looking for.

问题 I'm trying to use SQL Server Profiler (2005) to track down some application performance problems. One of the calls being made is to a table-valued user-defined function. This function wraps a select that joins several tables together. In SQL Server Profiler, the call to the UDF is logged. However, the select that underlies the UDF isn't being logged at all. Because of this, I'm not getting useful data on which tables & indexes are being hit. I'd like to feed this info into the Database Tuning

问题 I want to be able to see the code associated with the User Defined Function. I can see the name etc by doing the following, select * from information_schema.routines where routine_type='function' Which is all fine and dandy but I can actually see the code. Do I need to do this in SQL Server Management Studio, and if so how? Thanks for all the help, I'm a noob when it comes to IIS/MS SQL stuff. 回答1: In SQL Server Management Studio (SSMS) look under the Programmability\Functions branch. Since
