display message in console when no rows in output file

[Anonymous]

Hello,
I would wand to know how I can control the number of rows of a file. When there is no row it displays in the console "There is no row" and if there are rows I want to display "there is (number of rows)rows"
regards,

Hello,

well in the place of the tLogRow we can use a tJava to display the value of global variable from components with the commande System.out.println();

for example like this code :

System.out.println(((Integer)globalMap.get("tRowGenerator_1_NB_LINE")));

you can use a tJava component, and connect it to your database component via a "On Subjob Ok" link
in tJava you could use something like this:

if(((Integer)globalMap.get("tFileOutputExcel_1_NB_LINE")).equals(0)) {
System.out.println("There are no rows."); 
}
else {
System.out.println("There are " + ((Integer)globalMap.get("tFileOutputExcel_1_NB_LINE")) + " rows.");
}

or, to make it grammatically correct, and easier to read:

System.out.println("");
if( ((Integer)globalMap.get("tFileOutputExcel_1_NB_LINE")).equals(0) ) {
System.out.println("There are 0 rows."); 
}
else if( ((Integer)globalMap.get("tFileOutputExcel_1_NB_LINE")).equals(1) ) {
System.out.println("There is " + ((Integer)globalMap.get("tFileOutputExcel_1_NB_LINE")) + "row.");
}
else {
System.out.println("There are " + ((Integer)globalMap.get("tFileOutputExcel_1_NB_LINE")) + " rows.");
}
System.out.println("");

or you could use If links, like in the first attached picture
Note: the "System.out.println("***tJava_#***");" lines were just to show you which tJava_# the summary line printed from, and wouldn't be necessary in your solution
If (order:1)

((Integer)globalMap.get("tFileInputDelimited_1_NB_LINE")).equals(0)

tJava_1

System.out.println("");
System.out.println("***tJava_1***");
System.out.println("There are no rows.");
System.out.println("");

If (order:2)

((Integer)globalMap.get("tFileInputDelimited_1_NB_LINE")).equals(1)

tJava_2

System.out.println("");
System.out.println("***tJava_2***");
System.out.println("There is " + ((Integer)globalMap.get("tFileInputDelimited_1_NB_LINE")) + "row.");
System.out.println("");

If (order:3)

((Integer)globalMap.get("tFileInputDelimited_1_NB_LINE")) > 1

tJava_3

System.out.println("");
System.out.println("***tJava_3***");
System.out.println("There are " + ((Integer)globalMap.get("tFileInputDelimited_1_NB_LINE")) + " rows.");
System.out.println("");
