This will default the scope of the added variables to be "Foreach Loop Container". Before adding new variables, click on the Foreach Loop Container so it is chosen. Right click on the package area and choose Variables, a Variables window will appear on the left panel where the Toolbox normally locates. In the Control Flow tab, add a Foreach Loop Container from the Control Flow Items under Toolbox. ![]() A variable, "run", was also added to enable/disable the import of a certain file. The variable "path" was used in case the two files are saved in different locations. Table 1 illustrates the variables and their values. Thus, a set of variables need to be setup for them. Declare variables to be used by the Foreach Loop ContainerĪs mentioned earlier, I have two Excel files to import which means there are two source files, two select queries, and two destination tables.Add code to Script Task to import data from Excel.Map values to variables in Foreach Loop Container.Declare variables to be used by the Foreach Loop Container.I had two Excel files to load, so I used a Foreach Loop Container to load the two files. This method is to use Script Task inside SSIS to open the Excel as a connection, query the data from the spreadsheet, and then load them to SQL. This method is fast but needs some manual work. If your Office is an older version, you can create a new column next to it and use the Text() function to make the conversion. If you convert it by right click on the column and choose convert to Text, then SSIS will be able to see all the data correctly. And the values in Zip_Code were aligned to the right indicating it was a value field. ![]() As you can see in Figure 1, the values in SSN were aligned to the left which means it was a text field. The quick fix is to convert the values in the Zip_Code column to TEXT format in Excel. I chose to go with the second method so that the process is completely automated. After spending a few hours trying different methods and reading articles online, below are the two solutions I found. ![]() I tried to save the file as CSV format or bulk insert the data to SQL in Script Task, however, they did not solve the problem. Obviously, the Zip_Code field was considered as a number field and any values having a dash were replaced by NULL.īecause our client could not provide the data in other formats and we must return the same zip codes to them, I had to find a way to resolve this problem. This happens because the driver samples the first eight rows of data and determines the data types of the fields (according to Excel Inserts Null Values by Allen Mitchell). Figure 1 and Figure 2 show one example: cell I11 in the Excel file (Figure 1) appears as NULL in SSIS if you preview the file in SSIS (Figure 2). Some DBAs or developers may have experienced that the Excel Source of SSIS would load NULL values of some columns even though the Excel file has real values. I was assigned a project to import two Excel files to our SQL 2005 server.
