I wanted to get rid off one data source in Tableau, that's why instead of using 2 different data source for one dashboard, I wanted to copy all relevant fields from one data source to other. Is there any way in Tableau, by which I can copy-paste tos field from one to other data source?
In the attached screenshot, I wanted to copy the advisor sales field in data source biadvisorSalesmonth24 to bitransactionPartnerDay365:
You cannot make schema or structure changes to a table / datasource from within Tableau. If advisor sales is not in the bitransactionPartnerDay365 data source, then you will have to keep both data sources in the workbook and join them together.
Now, if you are familiar with the datasets and know the necessary table layout, you could write a custom SQL command and use that SQL command to retrieve the desired data as a single data source.

I'm new to building SSIS packages, in fact this is my first package. I need to pull data from one DB view on Azure managed instance to an SQL on prem. I have built out the data flow and all. I'm moving data from a database view into a another database table but the destination table has a column that the source doesn't have hence my destination mapping view looks like (See attached image) How do I fix this or what are my options?
If this columns needs to stay empty in the source and you don't have it in source your best and only option is leave it like this. It basically needs to ignore it so no information will be fed. That will work.
In case you need information as current date you can add derivied column box in between your source and destination in your Data Flow where you can add current date or more columns that come from variable for example.
Its self explanatory that ignore(optional) means mapping for those columns can be ignored and if you want columns to be mapped with any calculated column you can do it by using derived column SSIS component Reference
As per your use case,try to use OLD DB component instead of ADO.NET component

I work in a sales based environment and our data consists of 'leads'.
Let's say we record CompanyName, PhoneNumber, Address1 & PostCode(ZIP). These rows a seeded with a unique ID in the schema.
The leads come in from various sources and are compiled onto a spread sheet and then imported into SQL 2012 using SSIS.
After a validation check to see if a file exists we then use a simple data flow which consists of an Excel source, Derived Column, Data Conversion and finally an OLE DB Destination.
My requirement I'm sure has a relatively simple solution. I understand what I need to achieve is the first step. I need to take a sample of data from the last rolling two months, if 2 or more fields in the source excel file match the corresponding field in the destination sql table then I want to redirect to another table.
I am unsure of which combination of components I could use to achieve this. I believe that Fuzzy lookup may not be what I am looking for as I am looking to find exact field matches, I have looked at the lookup component but I am unsure if this is the way to go.
Could anyone please provide some advice on how I can best achieve this as simply as possible.
You can use the Lookup to check for matches in your existing table. However, it will be fairly complicated to implement the requirement of checking for any two or more fields matching. Your expression would be long and complex basically consisting of:
(using pseudo code for readability)
IIF((a=a AND b=b) OR (a=a AND c=c) OR (b=b AND c=c) OR ...and so on
for every combination of two columns you want to test
I would do this by importing the entire spreadsheet to a staging table, and doing the existing rows check in a SQL stored proc that moves the data to the desired destination table.
I have a spreadsheet that lists customers, their supervisor information, and special feature codes that are listed on their account at the time the report was created.
I need to add a column to this sheet that lists the last active date that these codes were populated on the customer account.
I'm aware of how pull the info when the features were last active. However, I need to base my query based on these specific accounts and codes. What family of SQL Clauses can I use to read these preexisting values and return a corresponding date value?
Your question is a bit ambiguous. How are you populating the spreadsheet? Are you using an ETL application like SSIS or creating an Excel output from a SQL query in your database?
If you are populating an existing Excel spreadsheet, then create in that spreadsheet a new column called "Last Active Date" in preparation for populating it from the source.
If you are pulling the data from a database source, then there may be an associated history or archive table where you can find the pre-existing codes along with their corresponding dates. Here your database administrator and/or developer will be better equiped to assist you in navigating the database architecture. If the codes are no longer available in the source database, then no special SQL CLAUSE will assist. You cannot retrieve that which does not exist.
I have data in a spreadsheet which I have to upload in sql. The problem is that this data is quite crude. I need to rearrange the sheets in the excel file in terms of their relation with eachother. The first sheet has master data a colum of this sheet is to be linked to data in the other sheet. All I have is a sheet in which data is embedded. The relation between data is displayed using an expander button. Please tell me how I can rearrange this data fast? I think this can be done by running sql queries or ssis package but I'm not sure.
You can use SSIS package with multiple Source components (inside Data Flow) to access each sheet.
Once you can see both sources, you can sort all key columns using a sort component and then use a Merge Join to combine the two sets of data together
Using the subscription functionality of SSRS, I have automatically run reports in a scheduled manner and sent out e-mails with the results of the report. I have only done this using a single data source. My question is, can I do this while using multiple data sources?
My goal is to just run the same report across a collection of data sources, and then have all of the results from each data source get sent out in one e-mail as a subscription.
In my specific case, I just need a single row for each data source. My intent would be to form a table, with one row articulated for each data source.

This isn't clear because a single report can only be matched to a single subscription.

Do this in a single report that uses multiple data sources.

Sounds like you have two options here:
Use Linked Servers:
Linking Servers Link 1.
Create Linked Servers Link 2.
Write a query that returns a single line for each source and use UNION ALL to create a single result set/'table'.
Create a report that uses the multiple data sources.
Have a single row table for each source and then arrange the tables to look like a single one when rendered.
Create a single subscription for your new report that combines multiple data sources.
