Hi again with another question.

as in subject, I'm trying to show item 1 of all the lines of data from query into a scrolling list field.
the data back from query are 2 items, column "DOMANDA" and column "RISPOSTA"
I only am able to show all the 2 items so:

Code: Select all

set ItemDel to TAB
    put tRsTrovaDom  into field "txtDomTrovate"

in this way:

Code: Select all

set ItemDel to TAB
    put item 1 of tRsTrovaDom  into field "txtDomTrovate"

I've back only item 1 (column DOMANDA) but, only of the first line...

another try:

Code: Select all

 repeat for each line i in tRsTrovaDom
      put item 1 of line i of tRsTrovaDom  into field "txtDomTrovate"      -- item 1 contiene la domanda
   end repeat

stops with error:
"card "crdDomAperte": execution error at line 93 (Chunk: error in range start expression), char 1"

thanks for help

You mixed up repeat for each and repeat with

Code: Select all

repeat for each line tLine in tRsTrovaDom
      put item 1 of tLine  after field "txtDomTrovate"    
   end repeat

Or

Code: Select all

repeat with i = 1 to the number of lines of tRsTrovaDom
      put item 1 of line i of tRsTrovaDom  after  field "txtDomTrovate"    
   end repeat

By the way, watchout with "into" for a field within a loop.... It doesn't make sense (the content of the field will be replaced at each iteration of the loop).

Should be:

put item 1 of line i of tRsTrovaDom & return after field "txtDomTrovate"

... assuming each item is to be on a separate line.

Hi bangkok, Pete
I solved merging your answer both...

Code: Select all

set ItemDel to TAB
    repeat for each line tLine in tRsTrovaDom
      put item 1 of tLine  & return after field "txtDomTrovate"   
   end repeat

just one thing wrong:
I think to have in the column "RISPOSTA",in the table of the DB, some data divided in 2 or more lines. so I've a part of "RISPOSTA"(which should be ITEM 2) like ITEM 1, and show in the field "txtDomTrovate" reserved to the item1 "DOMANDE"
sorry I've forgot to clarify.... (DOMANDE mean questions, and RISPOSTA mean answer)

and how can I do in a better way?
in my case I haven't a lot of iterations but, in case of hundreds or thousand of them..... could be not the best.

ciao and thanks all

Here the problem is how you obtain the data from the DB, because your answers contain return char.
Example, if you dB is:

Code: Select all

|DOMANDA | RISPOSTA |
|--------+----------|
|1+1?    | 2        |
|--------+----------|
|names?  |Ale and   |
|        |Max       |
|--------+----------|

when you retrieve data with this code:

Code: Select all

put revDataFromQuery(tab,return,connID,tSQL) into tRecords

You obtain:

Code: Select all

1+1?    2
name?   Ale and
Max

You have to change the line separator char, for example with:

Code: Select all

put revDataFromQuery("+++","%%%",connID,tSQL) into tRecords

you get:

Code: Select all

1+1?+++2%%%name?+++Ale and
Max

This way you can separate values without problem with return char.

Hi Max,

looks like this has been solved in another thread:
