For this to work, you need to modify the FINISH button to Submit the page (instead of redirecting).

I needed to know which database column was the source for each column in the spreadsheet; this was not as simple as you might think because the labels from this report (that has a bewilderingly large number of columns) were quite often very different from the database column name.

Of course, you know and I know that this is not necessarily a simple thing; it is certainly not just an option to be enabled.

Depending on what exactly they mean by upload this data it may be reasonably easy to build or it could get quite complex.

Perhaps in some odd instances the user will have received the data from some system in fixed width, XML or JSON format but this is rare as this is typically part of the build of a system integration solution and users expect these to be harder.

Knowing these will help you choose the right approach and solution.

Will the columns in the file remain the same, or might they change all the time If the structure is not amenable to automated data matching, can the file structure be changed to accommodate our program Is the structure even in tabular form (e.g.

If its an Excel file, is all the data in one sheet, or is it spread across multiple sheets Should all the sheets be processed, or should some of them be ignored Can the columns vary depending on requirement might there be some columns in one file that dont exist in other files, and vice versa.

Ive received spreadsheets where some data rows were not real data rows, but merely explanatory text or notes entered by the users since they coloured the background on those rows in grey, they expected my program to automatically filter those rows out.

Im not including the more standardised data interchange text formats in this list (e.g.

XML, JSON) as these are rarely used by end users to supply spreadsheet data.

Your Mileage May Vary so test and evaluate them to determine if they will suit your needs.

Gerald Venzl, 2019 KiBeHas CSV parser a simple CSV parser in PLSQL written by Kim Berg Hansen, 2014 (this is a simplistic parser that will not handle all CSV files, e.g.

Of course, this requires that the columns be in exactly the right order.

Since Oracle 12.1 you can use the simple FIELDS CSV syntax to parse CSV files, e.g.

Since Oracle 12.2 you can modify some of the attributes of an external table such as file name directly in the SELECT statement, without requiring any ALTER TABLE Override External Table Parameters From a Query in Oracle Database 12c Release 2 (12.2).

This can come in handy for scripting the load of a number of CSV files on an ad-hoc basis into tables that already have exactly the same structure as those CSV files.

Internally, it creates a temporary external table to load the data.

Additional parameters can be added to change the filename, delimiters, field names, and other options.

This can be very handy when your client sends you some spreadsheets and you need to quickly load the data as one or more tables.

If required you can customise the generated pages to add your own processing.

The definition determines the target table, the unique column(s) for data matching, transformation rules, and lookups (e.g.

Once this is done, the following four pages will be created for you.

The process would be set up to only run When Button Pressed NEXT and would have a Condition Item is NULL or Zero P111ERRORCOUNT.

The result is that on the Data Validation (3rd) page, after reviewing the validation summary, the user clicks Next and the data is loaded and processed.

In this case, I would add the process to the Data Load Results (4th) page, When Button Pressed FINISH.
