The DROP tables action will delete the Tables and Indexes in your target database. These would have been registered by the TABLES and GetKeys actions and created in the target database by the PREPENV Action.
You will only drop the Tables and Indexes if a mistake has been made. For instance, if you have accidentally specified the wrong Source or Staging Database. Typically, you will not need to Drop and Re-Register tables to perform Subsetting iteratively. You can instead begin your next Subset by Truncating the existing Data Subset.
To run DROP, open The VIP Server Controller from your desktop or start menu. You must open it as an administrator.
Load your re-usable Config file for the current Subset. You should have created this when you ran a previous Action for the same Subset. Instructions for working with Config files are provided in this article.
Next, make sure the relevant .vip workflows are Put in Memory. See this article for instructions.
Next, complete the mandatory parameters in the "Run Flow" tab. If working from a Config file created for the current Subset, you should only need to update the parAction argument and enter any additional optional parameters. You will need to update
Specify "Drop" for parACTION:
Complete any optional parameters. See this Knowledge Base article for a full list of Arguments and example parameters.
Once you have parameterized the DROP Action, make sure your Configuration Spreadsheet, Subset Report and Log file are all shut. Next, click "Create File" and then click "Start" to run the action.
In the output dialogue, you will see "Flow execution completed on remote server. Please check logs for details." once the DROP Action is complete":
If you receive an error message in your output dialogue or log, please refer to this article to troubleshoot common issues. You can also run your Action on debug mode for a more detailed log. You can also check the Log File and Subset Report at this stage, to check that the Actions have performed correctly.
Check your Database to make sure the Tables and Indexes have gone.
Next, update your Configuration sheet in your Control Spreadsheet to specify the correct Source Database and Schema, and the correct Target Database and Schema.
Next, re-register the metadata and create the tables and indexes in your target database. Re-perform the following actions to do so:
Run DROP from the Command Line
To run DROP from the Command Line, first open your re-usable .cmd script in a text editor.
If you have already configured a .cmd script for one Subset Action and wish to edit and re-use that script, you should only need to set "DROP" for "Action".
Otherwise, configure all mandatory parameters in the .cmd script.
You can also specify optional parameters at this stage.
Make sure your Control Spreadsheet, the Subset Report, and any Log Files are closed.
Run the script to delete the Tables and Indexes from the Staging Database.
