How to use tfilterrow

Anonymous — Sat, 16 Nov 2024 14:15:53 GMT

Hi
I'm a new talend's user.
I have 1 excel file (input) and 1 excel file (out put) - very simple
I want to filter a column by numeric and by text.
For numeric, it's OK - it's ==
But, for the text filter, it's a real problem for me. I try to do a "like" because my text begin by "impaye.....". I want every line with "impaye..." begin.
I hope somebody understand me.
My english is too bad.
Thanks you

Why don't you try spelling it with a lower case "s" : startsWith instead of StartsWith ?

It appears that some of the rows in your input data have an empty field (in the column that you're filtering). You can use a try catch to reject the rows in which the field is empty.
I would make a routine with the method startsWithImpaie(String).
It could be like this :
public static boolean startsWithImpaie(String field) {
try {
return field.startsWith("impaye");
}
catch ( NullPointerException npe ) { return false; }
}
And then call it in my tFilterRow like this :
routineName.startsWithImpaie(row1.Column5)

I have an Excel spreadsheet and I want to ONLY retrieve rows for two types of references.

Reference = "A", "AB", "D","FF"....

I only want rows where Reference IN ("A", "FF"). Plus, once I have the rows who match I want to use t Map in order to massage the information into an output file

Can this be accomplished using tFilterRow
