SAS EG Tip 1: Deleting a Duplicate Row
This morning I needed to remove a single row from a 2.8 million-row dataset. Since I had a suspicion the row was an exact duplicate of the row above it, manually opening the dataset with SAS Enterprise Guide and deleting the row would be easier. I did have full rights to the dataset and the library – so this trick can be influenced by that fact. I am recreating what I did here with the CANDY_SALES_SUMMMARY dataset, which is part of the SAS Enterprise Guide sample library that I noted when discussing sample data sources.
After using PROC PRINT to determine the observation number for OrderID 4801, which was 12461, I did this:
- Opened the dataset and clicked the area above the row numbers and next to the column names. (Ctrl+G also works.)
- In the Go To Cell, type the row number from the Obs column. You can also select the specific column you want to view from the drop-down.
- Ta dah! I scrolled through the row and it was an exact duplicate. [The example does not show a duplicate record, so you’ll just have to take my word that was what happened. 😉 ]
To remove the row with code was going to create a lot of typing and a waiting. Using Update mode, you can directly add, edit, or delete the information in a single cell or row. In this case it was much quicker and I knew that I could regenerate the data if I needed to. Thus this was a low risk solution.
- To start Update mode, right-click a cell in the row. If you have ReadWrite permission, EG asks if you want to switch to Update mode. This is mainly a sanity check – Are you sure? This is because once done – it cannot be undone. Since this was a duplicate row, I was not worried.
- Right-click the row number to see a pop-up menu of options, such as Insert, Append, and Delete.
- Select Delete rows to remove the row.
Note: Delete cannot be “Undone”! Use your new found magic with caution young wizards!
SAS EG Tip 2: Editing a Cell
Once you have entered Update Mode (explained in Tip 1), you can make edits directly to the cell. For instance, if I wanted to change the region for this particular row, I just need to click in the cell and make the edits. This trick can be handy when you have a table that you use for formats, permissions, and so on.
SAS EG Tip 3: Inserting/Appending a Row
In Update Mode, right-click for the pop-up menu and select Insert Row. A window appears that prompts you for the location and number of rows you want to add. Then you can add the information you want in the row.
Note: If you want to add a row where there is only a few differences, just copy the row and paste it into your new row. Then make the needed edits.
