Develop: Editing Data Save
Estimated reading time: 65 minutesOverview
In this example you will build from the previous report where you built a Data Pull. Here, you will walkthrough the steps in order to Save Data using the Interject function ReportSave. This function makes it convenient to modify the data source right inside of your Excel report without having to edit the data source directly.
In this Editing Data Save example, you will set up a data save that will allow you to edit a customer's contact name and title right from within the Excel report.
Note: The Customer Aging Report used in this example is a report that displays a customer's outstanding balances. It is not normally used to edit a customer directly. However, for this walkthrough demonstration purpose, you will modify the report in order to do so.
This walkthrough involves 6 main steps:
- Set up a Data Connection (completed already)
- Set up a Data Portal
- Setting up the report to handle the save
- Set up the ReportSave function
- Set up the Stored Procedures (SP) to handle the save
- Test the Stored Procedure & ReportSave
Note: This example uses Microsoft's Northwind Database. To download a minimized copy of the Northwind database for use in these labs, see here.
Setting Up the Data Connection
For the Data Connection for this example, you will use the connection previously set up here.
Setting Up the Data Portal
Step 1: Navigate to https://portal.gointerject.com and log in. Click on Data Portals on the left side bar and then the NEW DATA PORTAL button.
Step 2: Enter the following details on setting up the new data portal and click "CREATE DATA PORTAL".
- Data Portal Code: NorthwindEditingData_Save
- Description: Data portal for editing data save
- Category: Demo
- Connection: NorthwindExampleDB_MyName (replace "MyName" with your name)
- Command Type: Stored Procedure
- Stored Procedure/Command: NorthwindEditingDataSaveSP
Note: You will create the "NorthwindEditingDataSaveSP" Stored Procedure later
Step 3: After creating the data portal, scroll down and click Click here to add a System Parameter and ensure the Interject_RequestContext parameter is set.
The System Parameter Interject_RequestContext will transfer contextual data to the Stored Procedure you will set up later. In this example you will not need this info but it is a good practice to set this parameter for all your Stored Procedures.
Setting Up the Report
Begin by opening up the report that was completed in the Data Pull. You will modify this report to set up the ReportSave.
Step 1: Ensure Market is entered as a Company Name filter and pull the data:
Step 2: Unfreeze the panes (if they are frozen):
Step 3: Highlight the first two rows, right click within the selection and click Copy:
Step 4: Right click row 3 and click Insert Copied Cells:
Step 5: Copy & paste the same 2 rows again this time by right clicking row 5 and Insert Copied Cells:
Step 6: Set up the configuration section:
- Enter [clear] in the last column (This will clear the messages when pulling)
- Clear all values in row 4 except the CustomerID, ContactName and ContactTitle (These are the column names that will be used to save to the data source)
- Enter MessageToUser in the last column on row 6 (The save will return a message in this column if necessary)
- Add a row below the row containing the ReportRange function (You will add the ReportSave function on this new row)
Setting Up the ReportSave Function
The only thing left to set up in this report is the actual ReportSave function.
Step 1: Click on the cell below the "ReportRange" function and enter =ReportSave() and click the fx button to bring up the Function Wizard:
Step 2: Enter the following details in the Function Wizard:
- Data Portal: Enter the Data Portal you set up in the beginning.
- RowDefRange: This range defines the unique keys in the data source for each row. In this case it is the CustomerID. Enter the single column range for the CustomerIDs and be sure to select one row beyond the last ID (to allow expansion).
- ColDefRange: Enter 4:4. This range contains the columns that will be saved.
- ResultsRange: Enter 6:6. This range represents the return message to the user.
Everything is now ready for the ReportSave. You can further customize your report with styling and colors if you like:
Setting Up the Stored Procedure
Now that the ReportSave function is completed, Interject can use it to generate an example Stored Procedure for your save.
Step 1: First click on the cell that contains the ReportSave. Ensure the Advanced Menu is displayed. Click on System and then View SQL Template For ActiveCell:
Step 2: Highlight the SQL code in the new window and copy the contents to the clipboard:
Step 3: Open up the database you want to use and paste the copied SQL code into a new query:
Add the RequestContext_Parse Stored Procedure
The template that is created by Interject references a Stored Procedure called "RequestContext_Parse". This SP will process the XML data that is passed to your SP via the "Interject_RequestContext" parameter. After processing this data, you will have SP variables you can use within your SP (e.g. "@Interject_UserID", "@Interject_LoginDateUTC"). In order for the Data save Stored Procedure to work, you will need this Stored Procedure. If you do not currently have it, you can create it. In your database, open up a new query and execute the following code:
/****** Object: StoredProcedure [dbo].[RequestContext_Parse] Script Date: 12/20/2022 11:23:26 AM ******/

Modifying the Stored Procedure
The SQL auto generated template by Interject is formatted based on the ReportSave function within your report. It includes the definitions you set in that function to build the Stored Procedure. It also includes some example code. Some of this code you may choose to use depending on your purposes but other code you will not need and can delete. The following walks you through the major sections of the code with instructions on the changes. Deletions are marked with red highlight, changes are marked in yellow.
Parameters
There are 2 parameters in the SP. The first one, Interject_RequestContext
, was the System Parameter you set up previously in the Data Portal. Again, this XML contextual information will be passed by Interject to the SP upon execution.
The second parameter is a TestMode
bit. If you are testing, you can set the value to 1 to print out detailed information upon execution. This will also rollback any changes so your database remains unchanged during testing.
Testing
The next section is a commented out code used for testing. If you want to test your SP, you can simply highlight the text within and execute it. Notice at the end the ContactName and ContactTitle data are sent for each row in your report. You can change this data if you desire for testing purposes.
Context Parameters
This section declares and sets variables with the RequestContext_Parse SP. This SP takes in the XML data sent by Interject and parses it into variables that you can use within your SP.
Error Message
The ErrorMessageToUser is declared as blank to begin with. If the execution of the SP encounters any errors, it will set this variable with a message.
Data To Process
This section declares a table variable (@DataToProcess
) that will be used to store all the data that will be processed in the save. Each record includes the corresponding row in Excel (_ExcelRow
), and a message (_MessageToUser
) that can be sent back to the user.
The last two columns (ExampleColumnKey
and ExampleColumnValue
) are just examples used to validate the data coming in. They are not used in this example so delete them. You also need to change the data types and size to match your data.
Inserting the Data to Process
This section will take the XML data sent by Interject from your report and put it into the @DataToProcess
table. Again, you can delete the ExampleColumnKey
and ExampleColumnValue
columns and change the data types and size to match your data.
Validations
Now that you have all the data from your report into a table, you can do some validations on it before your target data source is updated. This section will run through certain validations and marks the _MessageToUser
upon a check. This is example code. You can use and modify it to match your report and data or you can delete it. There are 5 parts:
- Validating a parameter is a certain value (not used in this example)
- Validating the data to save does not contain duplicate keys (change data type and size to match your data)
- Validating a required column is not blank (not used in this example)
- Validating a column has certain text (not used in this example)
- If any validation checks recorded a message, this SP will GOTO the end and not update any records (it will show the user the message on the corresponding row)
ChangeLog
You can delete the "CREATE TABLE #ExampleTableToUpdate" part, it is not used in this example.
Next, another table variable is declared. The @ChangeLog
table will be filled with information regarding the changes to the data, such as the row in the Excel report, the type of change that was done, and the corresponding key.
Merge
This section is where the data from your report (located in the @DataToProcess
table), is merged with the target table in your database. It first declares a transaction. This is so the following changes can either be committed if no errors or rolled back if there is an error.
Next it merges by joining the tables on your key and updating the desired columns when there is a change detected.
Finally, it outputs the change information to the @ChangeLog
table.
Set Message To User
This section sets the message that will be displayed to the user by comparing the action values in the @ChangeLog
table. You can change the message to anything you like.
Final Response To User
This last section simply returns the message on each row back to the user. This could be an "Update" or an error message if it was set previously.
It also raises an error message if the parameter @ErrorMessageToUser
was set.
Final Stored Procedure
Now that the Stored Procedure is finished, execute it to save it.
The following is the finished SP:
CREATE OR ALTER PROC [dbo].[NorthwindEditingDataSaveSP]
-- System Params not in formula
@Interject_RequestContext nvarchar(max)
,@TestMode bit = 0 -- used only for testing the stored procedure directly. It will show more results when set to 1.

Testing the Stored Procedure
Now you can test the SP by using the test code. For example, make a change to the data in the test code and execute the test. Because the @TestMode
bit is set to 1, it will display all kinds of information about the SP process. Notice the changes and message to user that would be displayed.
Note that when using the test script, no actually changes are being made to the database since the transaction of the merge is rolled back:
Testing the ReportSave
The only thing left to do is test the SP by running the ReportSave function within the Excel report.
First pull the data:
Next make a change to a Contact Name or Contact Title and run the Report Save:
Notice the results!:
