Question: using the value of a field as field name in Script

[obmk]

Hello,

I'd like to know please if there is a way to use the Value/Content of a field as field name in the AS of a LOAD statement.

Example:

In a Table 'Maschinen' there is (among many others) a field 'MaschID' like
'TP01_01_01'
'TP01_01_02'
...
'TP_02_01_01'
...

In al LOAD statement, I check the MaschID and collect data like this:

TempData:
load

foo1 as bar2,
foo2 as bar3
...

resident Maschinen
where left(MaschID, 4) = 'TP01';

So far. Now, I want to use the value/content of each 'MaschID' to build a reference with the "... AS ... " to another table 'ProductionSites' which has some colums named exactly like the value of MaschID. i.e. (in pseudo code):

TempData:
load
... as getTheValueOf(MaschID)

resident Maschinen
...

Unfortunately, getTheValueOf(MaschID) does not work.... 🙂

Does anybody know a/the solution?

Thanks a lot in advance

Hello Snoman,

One workaround may be to load a table with all possible values from your field, then do a for loop and for any possible value of that first table, load a second table with renamed fields. Using for will take a lot of time though. It should look like (untested)

FieldWithValues:LOAD MaschID RESIDENT Maschinen;FOR i = 1 TO NoOfRows('FieldWithValues') SET vTempFieldName = FieldValue('MaschID', $(i)); TempData: LOAD TempField as $(vTempFieldName) RESIDENT Maschinen;NEXT

Thanks for the quick response Miguel and thanks for this idea. It'll gonna really time comsuming because I have quite huge tables... but your idea brought me to some more searching and I got this posting from John Witherspoon touching the topic under "dynamically load".

I'll build my lines and will then post them here.

Thanks!

Best
