multiple tables in a sheet and stop load script manually

Anonymous — Wed, 25 Nov 2020 16:16:04 GMT

Hi guys,

I wuold your opinion about my strategy.

This is the situation: I've an excel with one sheet and inside this there are multiple tables.

Each table is separated from the next one by two empty rows.

I want load the table from the beggining of the sheet and every time that I found an empty row I want increment a variable by 1.

Furthermore I want add where condition at the end of load script: when variable's value is >= 2 I'll stop the load script.

What do you think about this strategy?

How can I force the exit from load script?

Thanks.

Hi Andrea,

How can I force the exit from load script?

Use Exit Script function in script level.

Thanks ,

This couldn't be done with single-load else you will need a multi-step approach.

This could be for example to load the whole sheet with all the tables into a single table, identifying each sub-table (header and data separate) with various check-statements and then splitting the tables again with the help of these identifying-data whereby you need an additional step to extract the table-header and creating a mapping table for an appropriate rename-statement.

Another approach would be to use the FIRST statement in combination of the (... HEADER is n lines ...) from the file-format. But with this method you must also know when a table begins and end - this meant you need before a load which identified them by using recno(), rowno() and various check-statements maybe in combination with interrecord-functions like peek() or previous(). With this kind of data you creates a for loop which picked the first/header information into variables which is then used within the load-statements.

The second approach here is in my opinion the easier one and with a quick look in the help to the mentioned statements and functions you could start and I think with a few trials you will understand the above described logic and after them it's just a matter of adjusting the identifying routines.

Peek() or Previous() ?

RecNo or RowNo?

Loops in the Script
