I am totally new to the SSIS. I have a requirement to create a text file on specified location and write the data in it which is selected from SQL table.
How to do that?
Is there any example which will help me?
The below steps should help you to get a basic SSIS package working:
Create new Integration Services Project in Business Intelligence Development Studio. There should be a default SSIS package in it called Package.dtsx. Open the package.
In the bottom of the screen, there should be an area for connection managers. Right click on it to get a list of different connection managers.
Click on New OLEDB Connection. This will be the connection manager for your source database. Set the data source (server or instance name), authentication mode and credentials and the initial catalog (database name).
Again right click in the connection managers area and select New Flat File Connection.This will be the connection manager for the destination flat file. You can create a text file (.txt or .csv) and add in the headers for your data e.g. EmployeeID,EmployeeName,EmployeeSalary. Check the "column names in the first data row" checkbox to make sure your headers are identified as such.
Now select a Data Flow Task and drag it to the Control Flow screen.
Open the Data Flow tab. Drag 2 items from Toolbox to the screen - OLEDB Source and Flat File Destination.
In the Source, use the OLEDB connection manager created earlier. Then change the Data Access mode to SQL command. Now you can type your own command to select data. Make sure that the header data in your flat file is the same as the column headers from your select query.
In the Destination, use the Flat File connection manager created earlier. Go to the Mappings section and map the columns from your query output to the headers in your text file.
Now save and run the package. You should see that the destination text file is populated with data from your query.

Export data from SQL Server to Excel and Excel file via using SSIS package :
Configure ADO.NET connection :
To create a “Source” connection, right click “Connection Managers” and select “New ADO.NET Connection”.
a. Server Name – is the hostname or IP address of the database server where SQL is installed.
b. Authentication – is an “authentication type” used to connect Server that is selected on “Server Name” drop-down box. It can be either SQL Authentication or Windows Authentication.
c. Database Name – is the name of the database which we are going to use for data extracting.
Configure ADO.NET Source :
To populate data from SQL Server table, you must configure ADO.Net source component.
Double-click on “Data flow task” to do that. The window “Configure Data flow task” will open. Alternatively, you can select “Data Flow” that is located next to “Control Flow”. As we already configured SQL connection, we will drag and drop ADO.NET Source to data flow window.
Then select “SQL Command”, it will open a multi-line text box where we can write the Ad-Hoc query to extract data from the database.
Configure excel destination
Once we configure ADO.NET source, we will configure Excel destination.
In SSIS tool-box, drag and drop excel destination in the data-flow window and rename it as “Sales Excel File”.
a. Excel connection manager – used to connect the excel file.
b. Data access method. Excel worksheet is considered as a table or view. If you select “Table or View”, drop down box “Name of excel sheet” will be filled with all worksheets that are created in the excel workbook.
c. Name of excel sheet. By default, this drop-down box is disabled. It will be enabled automatically when we select “Table or View” as data access mode. We also can select appropriate excel worksheet.
Then, choose :
a. Excel File Path – the location of the excel file.
b. Excel version – can select excel version from drop down box.
In order to export data from SQL table to excel file, you must map the fields of SQL table and Excel file.
To do that, drag blue arrow beneath the ADO.NET component and drop it on Excel Destination component.
Double click on “Excel destination” to map the fields. “Excel destination editor” will open. Select “Mappings” option from the left pane of the dialog box. In mapping, input columns will be the columns of SQL Query output and destination columns will be the columns of the excel file. It is suggested to keep the same name of SQL Query output and excel columns. This will make mapping much easier because we do not need to map fields manually. SSIS will map columns automatically.
I have created an Excel workbook with SQL server connection and loaded data using SQL commands. I want to use the same excel file in a different machine, there I want to change the database credentials. In our excel file, there are more than 10 SQL server connections and sheets, So recreate the file is very difficult. Is there any way to reuse the file with a different database?
I have copied the excel file with all .odc files, But I couldn't find an option to reset the connection to the new database.
I see two possibilities:
Edit the ODC files manually with a text editor
In Excel, use "Data" -> "Connections" to edit the connections
I have multiple packages for each location site and each site contains 5 other sub sites for which data has to be populated every month. Hence I have approx 20 excel files as a source data for which the excel file acts as a source and I need to create an excel destination. Because of so many excel file as a source I have multiple Excel connection Managers (Source + Destination) across my various packages.
The source file name and the location will change everytime and so I was thinking to automate the file path via parameter. I follow the steps mentioned in the article: https://blogs.msdn.microsoft.com/sqlgardner/2015/06/18/ssis-tip-using-a-file-path-parameter-for-multiple-flat-files/
I followed every step but I got the error when I open the excel file (source). Below is the error snapshot:
Can someone guide me what exactly I am doing wrong here?
Looks like you're using an expression on the excel connection manager "ConnectionString"
property. When that property is changed to just a file path that isn't a valid connection string for that type of connection.
With excel file connections it's a little different and you'll want to use the ExcelFilePath property, which in turn is used by the connection manager when building out the connection string.
With Flat File Connections, yes you would use the ConnectionString property, Excel Connections, slightly different, use the ExcelFilePath property.
I am using VS2017 and SSMS 2017 and imported a CSV file in FLAT FILE option in Data Flow tab in SSIS and also created anADO NET SOURCE database connection through my local server that stores the data in my database. But when am trying to create a connection between FLAT FILE and ADO NET SOURCE, by dragging the blue arrow from file option to ADO NET option, am getting this error. Can anybody provide some input on how to get rid of this error?
enter image description here
You are attempting to route the flat file source into another source component, which cannot be done. Did you mean to route the data into a destination?
Error is that you have connected Source to Source.
Fix it by connecting Source to Destination, so that the package can build successfully.
Replace your ADO.NET SOURCE with ADO.NET DESTINATION and this error will be corrected.
I have to insert data into two tables from two different excel sheets using SSIS packges.
So, please some one tell me How to import multiple Excel files into SQL Server 2008 R2 using SSIS Packages?
since you have only 2 excel files and only two tables I don't see why use a foreach loop. Just follow this link and do it directly
If you need to insert from both excel files to both databases you can use a multicast component to create a copy of a dataset
Use Foreach Loop Container --> Foreach File Enumerator. Then put your Data Flow in Foreach Loop Container.
Table structure and sheet name have to be equal in every Excel file.
Here is nice tutorial:
http://bi-polar23.blogspot.com/2007/08/loading-multiple-excel-files-with-ssis.html
You can create and use variables to hold Excel file path, then implement the package within a for-each-loop container to loop trough each excel files in the folder. Make sure that the files are having similar data format and same extension.
Create an integration service project in Visual Studio and follow the steps below:
Right Click on canvas and add Variable say "FilePath" and set type
as String
Drag a for-each loop to canvas
Right click on for-each-loop and select "Edit" and add path and file extension and then select the variable from "Variable Mapping" tab as shown:
Add a Data-flow task in to the loop and double click to open it.
Add an Excel source and OLEDB destination (if destination is SQL Server). By right clicking on these controls and choosing "Edit", you can select appropriate folder for Excel and its Data Sheet as well as specify SQL server database credentials in the destination. Connect source and destination using blue arrow. Check and modify mappings between columns, if needed.
Create an expression to read each file to the variable. This can be done by selecting created "ExcelConnectionManager" and select its "Expression" property and expand to set variables to "ExcelFilePath"
And that is it. You are ready to execute the package by coming to Control flow tab and select "Start".
