问题 hi im having trouble trying to get the following function to work. CREATE FUNCTION test ( @nt_group VARCHAR(128) ) RETURNS @nt_usr TABLE ( [name] [nchar](128) NULL , [type] [char](8) NULL , [privilege] [char](9) NULL , [mapped login name] [nchar](128) NULL , [permission path] [nchar](128) NULL ) AS BEGIN INSERT INTO @nt_usr EXEC master.dbo.xp_logininfo 'DOMAIN\USER', @nt_group RETURN END As far as i know i should be allowed to call an extended stored procedure, im getting the following error

问题 All, This is a follow up for my question here. My setup: Visual Studio 10 Language C# Excel 2007+ Windows XP+ What I would like to achieve is this: Create VSTO addin for Excel with a custom Ribbon component and a custom Task Pane Create an RTD server Create some UDF's that wrap the =RTD() -calls for the Excel users Have the clients install the Addin through a ClickOnce installation Apart from the last requirement, I am basically done. The only problem I have is to get the RTD server and the

问题 This question already has answers here : SQL Server 2008 - How do i return a User-Defined Table Type from a Table-Valued Function? (4 answers) Closed 4 years ago . Is it possible that a multi-statement UDF return a User Defined Table Type, instead of a table that is defined within it's return param? So instead of: CREATE FUNCTION MyFunc ( @p1 int, @p2 char ) RETURNS @SomeVar TABLE ( c1 int ) AS I would like to do: CREATE FUNCTION MyFunc ( @p1 int, @p2 char ) RETURNS @SomeVar MyTableType AS

问题 I am trying to count the number of times the current row's value for a specific column 'df1' falls between the low-high range values in the previous 5 rows (in 2 side by side columns). This is a follow-up question - Dickster has already done the heavy lifting here. The Series().between() method is not cooperating, complaining that AttributeError: 'Series' object has no attribute 'columns' . I don't understand how I am involving the columns attribute. list1 = [[21,101],[22,110],[25,113],[24

问题 I assume this is not deterministic simply because DB_NAME() is not deterministic? If DB_NAME() is not deterministic, why is it not deterministic? ALTER FUNCTION [TheSchema].[udf_IS_PRODUCTION] () RETURNS bit WITH SCHEMABINDING AS BEGIN RETURN CASE WHEN DB_NAME() = 'PRODUCTION' THEN CONVERT(bit, 1) ELSE CONVERT(bit, 0) END END Update: This version works, is deterministic, allows the same code to be used in any database and removes the hardcoding of the database name (which also allows me to

问题 I have a function that splits up a string (pasted at the end for clarity). This function works as expected when used alone. Example: SELECT value FROM dbo.mg_fn_Split('2#1','#') Returns -- value -- -- 2 -- -- 1 -- ----------- But when used in a "WHERE IN" clause, as in this example (more on tableA later on): SELECT * FROM TableA WHERE TableA.id IN ( SELECT value FROM dbo.mg_fn_Split('2#1','#') ) I get the error: "Invalid length parameter passed to the LEFT or SUBSTRING function." TableA is

问题 Chrome V8 - the JavaScript engine - recently added support for BigInt - arbitrary precision large integers: https://developers.google.com/web/updates/2018/05/bigint Can I use these BigInt in BigQuery? 回答1: Yes! BigQuery runs one of the latest versions of V8, so it already supports BigInts. To use them: CREATE TEMP FUNCTION testBigInt() RETURNS ARRAY<STRING> LANGUAGE js AS """ return [ Number.MAX_SAFE_INTEGER , Number.MAX_SAFE_INTEGER+2 , Number.MAX_SAFE_INTEGER+1 , Number.MAX_SAFE_INTEGER+100

问题 I am trying to load up my own UDF in pig. I have made it into a jar using eclipse's export function. I am trying to run it locally so I can make sure it works before I put the jar on HDFS. When running it locally, I get the following error: ERROR 1070: Could not resolve myudfs.MONTH using imports: [, org.apache.pig.builtin., org.apache.pig.impl.builtin.] Script REGISTER myudfs.jar; --DEFINE MONTH myudfs.MONTH; A = load 'access_log_Jul95' using PigStorage(' ') as (ip:chararray, dash1:chararray

问题 G'Day, I want to use the Windows API Postmessage() call from inside a MySQL UDF on MySQL 5.1.51 (XP SP3). I know the UDF (Written in Delphi 2006) is working by setting a bogus result for the UDF. The syntax of the UDF takes two integer params, one for a window handle and the other for a message number. However a call to PostMessage() from inside my UDF causes an exception in mysqld and the service stops. Any ideas or pointers? Alternatively if anyone can tell me how I am able to simulate IB
