If you have different names at source and different names at destination then columns will not map automatically then you have to mapped them manually. Columns names are mapped automatically by default. Next, click on the Mappings tab to check whether the source columns exactly mapped to the destination columns. Now double click on OLEDB destination to configure the connection manager settings. Next, we will select the OLEDB destination and drag it to control flow region then connect Flat file source to OLEDB destination as shown below. Now just click on OK button to close the Flat File Source Editor. In this tab, you can uncheck the unwanted columns that you do not want. Next, click on Flat File Source Editor columns tab to verify the columns. After that you can click OK button to close the Flat File Source Connection manager Editor. Next, In Preview tab you can see the preview of data. Next, In Advance tab, you can configure the column properties such as modify data type, column name, delimiter as shown below. Next, click on columns tab to preview the column data and modify the row and column delimiters as shown below. Now you need to provide a source file path.Īt this moment you can select any file from folder later we will replace that file path with expression to get file names dynamically.Īfter that, just take a look at text qualifier, row delimiters and check the option column names in first row, if the first row has column names. You can see, Flat File Connection Manager Editor window opens. Now double click on Flat File Source to configure the connection manager settings. Now double click on Data Flow Task, it opens the Data Flow tab.Īfter that, select Flat File Source and drag to Control flow region as shown below. Now, select Data Flow Task and drag it inside Foreach Loop Container as shown below. Now you can see the newly created variable as shown below. Next, we have to store the file name and extension in a variable so that it can be used in Data Flow Task.įor this, just click on Variable Mappings tab then create a new variable as shown below. Lets select the Name and Extension option as shown below. Traverse subfolders: If you want to check the subfolders, please checkmark this option.Fully Qualified: If you select this option, the Foreach loop store the path, file name, and extension in the variable such as E:\SSIS_Work\Sales\Sales1.txt.Name Only: If you select this option, the Foreach loop will store the file name in the variable such as sales1.Name and Extension: If you select this option, the Foreach loop will store the file name and extension in the variable such as sales1.txt.Next, you need to select the file name in Retrieve file name property and it has few options as follows: Once you click on Evaluated Expression you can see it displays the input folder path in Evaluated Value window which means expression is correct.Īfter that close the Property Expression Editor window. Just select the variable and drag to Expression window then click on Evaluated expression to validate the expression. In Expression Builder, expand the variables and Parameters folder under that you can see the variable that you created named InputFolderPath. Select Directory in Property dropdown after that click on ellipsis ( …) to provide the directory path. Just double click on ellipsis ( …), and you can see a Property Expressions Editor window opens as shown below. Here, we have selected Foreach File Enumerator because we want to loop through the files present in folder. Now click on Collection tab, select Foreach File Enumerator from Enumerator property. Just double click on Foreachloop Container, and you can see a Foreach Loop Editor window opens. Once you create the variable, next we will configure the Foreach Loop Container. Lets create a new variable and assign it an input folder path as shown below. Now, lets create a variable that will store the folder path from where we will be reading the files. Note: The Foreach Loop container repeats a control flow task in SSIS package. Lets open SQL Server Data Tools and create a new SSIS package.Īfter that, select and drag Foreach Loop Container into Control flow region, the Foreach loop container will reads the files present in Sales folder and loop through one file at a time and load the file data into SQL table. So the Data from all flat files will be loaded into this table. It has same number of columns that we have in flat files. Here you can see, we have a table named SalesData. Lets go step by step and see how to build a package to load all flat files into table that are present in folder Sales. csv files to a SQL Server table.Īs you can see here we have two flat files named Sales1.txt and Sales2.txt under folder Sales.įile Sales1.txt has 4 records while Sales2.txt file has 2 records only. This article demonstrate how to load multiples.
