In this article we will show you, How to transfer SQL Server User Defined Functions from one Database to another Database using Transfer SQL Server Objects task. If you want to transfer the Stored Procedures then please refer Transfer SQL Server Stored Procedures in SSIS article.
Transfer SQL Server User Defined Functions Using Transfer SQL Server Objects Task in SSIS
If you observe the below screenshot there is one Database called [Duplicate AdventureWorks2014]. We already Transferred the tables from [AdventureWorks2014] using Transfer SQL Server Objects task. Please refer Transfer SQL Server Tables with Data in SSIS article to understand, How to Transfer SQL server tables.
In this example, we are going to transfer the User Defined Functions (Both Table Valued Functions and Scalar Valued Functions) from [AdventureWorks2014] to [Duplicate AdventureWorks2014] using Transfer SQL Server Objects task.
Before we start creating the package, Let us see the User Defined Function in [AdventureWorks2014]
From the above screenshot you can observe that, [AdventureWorks2014] Database holds one Table Valued Functions and 10 Scalar Valued Functions. Our job is to transfer one Table Valued Functions and 9 Scalar Valued Functions (except ufnLeadingZeros Functions) from [AdventureWorks2014] to [Duplicate AdventureWorks2014] using Transfer SQL Server Objects task.
Now let us see the Destination Database
From the above screenshot you can observe that, [Duplicate AdventureWorks2014] Database holds one Scalar Valued Functions.
STEP 1: Open BIDS and Drag and drop the Transfer SQL Server Objects Task from the toolbox to control flow.
Double click on the Transfer SQL Server Objects will open the Transfer SQL Server Objects Task Editor to configure it.
General Tab
In this tab you can write your own Name and description as per the project requirements.
Here we haven’t changed any. Click on the Objects Tab
STEP 2: Select the SourceConnection property and click on it to create New connection. If you already created then select it.
Once you click on <New connection…> an SMO Connection Manager Editor window will be opened to configure the connection.
STEP 3: For this example, we are selecting our localhost instance and we are using Windows Authentication. If you are working for an organization then select the SQL Server Authentication and provide the credentials.
Click on the Test connection button to check whether the connection is throwing errors or not.
STEP 4: Click on the SourceDatabase option and select the database you want to use. For now we are selecting [Adventureworks2014] as shown below.
STEP 5: Select the DestinationConnection property and click on to create New connection. If you already created then select it.
We already mentioned localhost instance in SourceConnection and here also we are going to use the same instance. If you want to create new one then click on will open SMO Connection Manager Editor window to configure the connection.
STEP 6: Click on the DestinationDatabase option and select the database you want to use. For now we are selecting [Duplicate AdventureWorks2014] as shown below.
STEP 7: If your requirement is to copy all the objects (views, function, stored procedures, tables) from the source database then set CopyAllObjects option to True. In this example, We are going to send User Defined Functions only so we leave it to default False.
If we set CopyAllObjects option to False, next property ObjectsToCopy will get enabled.
STEP 8: Click on the ObjectsToCopy property to configure it. ObjectsToCopy property will explore many options of the Transfer SQL Server Objects Task. Let us concentrate on options that belong or related to this example. In this example, Our requirement is transferring the User Defined Functions so we have to understand options such as CopyAllUserDefinedFunctions and UserDefinedFunctionsList.
If your requirement is to copy all the User Defined Functions from the source database then set CopyAllUserDefinedFunctions option to True.
STEP 9: Click on the UserDefinedFunctionsList option and click on the collections. Once you click on the (…) button besides Collections, it will open the Select User Defined Functions window to select the available User Defined Functions from the source connection.
For this example we are selecting all of them except ufnLeadingZeros Functions but you can try with different options.
STEP 10: Click ok to close the Select User Defined Functions window and then click ok to finish configuring the Transfer SQL Server Objects Task.
Let us run the package to see whether we successfully transferred the SQL Server User Defined Functions from source to destination.
Let’s open the SQL Server Management Studio and check for the User Defined Functions.
From the above screenshot you can observe that, We successfully transferred the SQL Server User Defined Functions. They include one Table Valued Functions and 9 Scalar Valued Functions.
