[resolved] SELECT query from tPostgresqlInput and storing reult in variable?

[_AnonymousUser]

Hi.
My job is roughly this:

tFileList --(iterate)-> tFileInputDelimited --(row1)-> tMap --(out1)-> tPostgresqlOutput
   |
   |
(iterate2)
   |
   v
tPostgresqlInput (for calling SELECT function() to further process data in db)

ie. I load data from files (iterating) to a DB and after each
iteration, I call a function in tPostgresqlInput to further
process the data in the DB. The function returns a value
that I would like to write to a variable and later write to a
log file of as sort. But how do I write the value to a
variable?
Later in process the file writing part would connect to
the tFileList above with another iterate arrow ( iterate3)
to log the file name loaded and the value returned from
the function, pretty much like this:

   ...
    |
(iterate3)
    |
    v
tFileProperties-(row3)->tMap -(out3)-> tFileOutputDelimited

So basically my question is: how to write a single value
selected from tPostgresqlInput to a variable?

Hi,
You can use tJavaRow  to save each value to a variable for re-use in the next Input component.

OK, I solved this with tSetGlobalVar component like this:

tFileList --(iterate)-> tFileInputDelimited --(row1)-> tMap --(out1)-> tPostgresqlOutput
  |   |
  |   |
  | (iterate2)
  |   |
  |   v
  |  tPostgresqlInput --(row2)-> tSetGlobalVar
  |
  |
(iterate3)
  |
  v
 tFileproperties --(row3)-> tMap --(out2)-> tFileOutputDelimited 

Then in components:

tPostgresqlInput: add field in schema for the value (code)
tSetGlobalVar: "code" as key, row3.code for value
tMap: ((String)globalMap.get("code")) in out2

Please feel free to share better solutions.
