问题 I have a folder having multiple files with the name as P04_20140326_1234.zip P04_20130324_58714.zip P04_20130808_jurhet.zip P04_20130815_85893.zip etc The name is in the format P04_systemdate_*.zip. I want to pick the folder containing currentdate in the name and unzip it first and load the data from extracted file into the table.eg : file named as A.txt goes into table A, filenamed as B goes into table B and so on... 回答1: I guess you have already done the following: Add a Data Flow Inside

问题 I got a package that runs through a folder and it's sub folders to get client data. The agreement has changed and now the client will post his data in different folder name every time. I was wondering if I can do a foreach loop on the main folder and exclude specific folders like archive . I don't have knowledge in writing scripts so I was wondering if SSIS can do that without the script. 回答1: Using Execute Script Task Get List of - filtered - files using an Execute Script Task before

问题 This is typical ForEach container behaviour: However, if I do whats shown in the image below, the Execute SQL task never executes, how can i do this behaviour? I do not have to use ForEach container if some other type of container will allow me to do this. The for each loop essentially loops through files in multiple subdirectories in a folder. Based on which folder the loop is in, it populates a variable. this variable is used in the connectors from "some script" task to "task a" and "task b

问题 I am using a for each loop container in SSIS package where I am passing a list object as enumerator to container. If the list is empty the for each loop container is getting failed. Is there any way to pass the container even if the list object is empty? 回答1: Is the List object you're passing to your container really an empty list, or is it null? The Foreach Loop container will quite happily iterate through an empty list (and do nothing), but will fail with an error message such as this if

问题 I declare two variables as "Object" named a and b, and have a simple SQL task:. select code from code_list Using Full result set, I'm trying to pass the result to the variables declared(a and b) , and use them(a and b) on Script Task with two different foreach loops 。But it didn't work. Script Task: insert the result into two different tables(A and B). 回答1: Create 3 variables of type Object, only use one as ResultSet. Then Add a Script Task, and select 3 variables as Read/Write Variables.

问题 I would like to create this in SSIS package, wherein, it will loop in the list of files in a directory or folder and check each files if it exist in a SQL queried table. If the filename does not exist in the table, it will be archive in a different folder. Thanks is advance for any help! =) 回答1: You could use a For each Loop container that can be pointed to the said directory or folder and then store the file name (Name and Extension, Fully Qualified or Name only depending on the requirement)

问题 I have used a web service task to give the following result in XML File as follows, <?xml version="1.0" encoding="utf-16"?> <Data xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Name xmlns="http://Iycon.com/WebService">Reshma</Name> <BirthDate xmlns="http://Iycon.com/WebService">1988-09-23T00:00:00</BirthDate> </Data> , now I am intended to insert two values in database, initially I worked with single value and I inserted that value into

问题 Creating a package that will loop through all the servers in our different environments(DEV, UAT, PROD). We use service accounts and there is one service account for DEV and UAT and another for PROD. I am using a ForEach Loop Container/variables to set the connection string. The issue: When the data flow in the loop trys to connect to the PROD servers they fail because they are using the DEV/UAT service account which obviously doesnt have access to PROD, which is fine. The problem is this

问题 This was my original code #include "stdafx.h" #include <string> #include <list> #include <algorithm> using namespace std; class testing { public: int value; testing(int v) { value = v; } int getval() { return(value); } }; void func(testing& ob) { printf("The value is %d\n", ob.value); } int _tmain(int argc, _TCHAR* argv[]) { std::list<testing> testvar[3]; testing t1(0); testing t2(1); testing t3(3); testvar[0].push_back(t1); testvar[0].push_back(t2); testvar[0].push_back(t3); std::for_each

问题 I need to keep a check on the iteration number for a foreach loop container task that I am running in Visual Studio 2017. How could I achieve this ? 回答1: (1) Count iterations using Expression Task Task available in SSIS 2012+ In Foreach Loop container, there is no properties that contains the iteration number. You can achieve this by creating a SSIS variable of type Int, with a initial value equal 0 . example @[User::Counter] Inside the Foreach loop container, add an Expression Task with the
