Now, lets continue to imagine that you have a corresponding table in SQL Server: So, the situation is thus; We want to update records that exist in both the table and the Excel file and insert those that exist in the Excel file but not in the table. Under Control Flow we need to add a new Control Flow Item – Data Flow. Now double click on this item, or select the Data Flow tab.
I have many workbooks that point to a single workbook A (master workbook).
Each external worksheet has a unique cell that it references in workbook A column G.
Master workbook A is in alphabetical order and column G is updated frequently.
To do this we use a conditional split where we ascertain if the UID is null (from the database table), if it is we know this is a new row and so should be inserted into the table, if it isn’t we know this row exists in the table and so the row should be updated (perhaps one of the column values has changed).
If you have already created a chart in Excel, you can embed and link it to your Power Point presentation.
When you embed an Excel chart in Power Point, any updates you make to the original Excel chart will automatically update in your presentation, as long as the files remain in the same location.This helps the data stay in sync, so you won't have incorrect or out-of-date information in your chart. An Excel spreadsheet containing the chart's source data will appear.After you have finished editing, be sure to save the chart in Excel.Once you have embedded a chart, be careful not to delete or move the original Excel file.If the location of either the Power Point presentation or the Excel file changes, you may have to embed the chart again in order for it to display correctly.I have a many to one workbook/spreadsheet situation.
