Thread: Truncate String

  1. #1

    Default Truncate String

    hi everybody

    i have a little problem while i do a transformation

    i have a string field named DESCRIZ string(40) and with SelectedValues step i rename it into ART_DESCRIZIONE1 string(30), but i see that some records are not trunced

    why this happens?

    if i specify a lesser length into SelectValues step, doesnt Kettle truncate the field? how can i truncate the string i need to be shorter?

    Ooh... one of my favorite questions Have a look at for the answer.

    Kettle does not limit the values to the size of the metadata, conversion is only done at the very last stages.

    If you really want to cut... you can use e.g. javascript step or use the trimcut step that can be downloaded at (trimcut only if you're using v3 of Kettle)

    i checked some rows he wrote in the destination DB

    i see that the strings are trunced in automatic

    any way... there is a problem now..

    the trasformation is ok, when i VERIFY it, there is no error...

    but after somer rows it crashes

    the input database is a MDBaccessDB

    the output database is a ACUCoboldDB, to which i refer through an access file, made with linked tables

    in both connection option i set
    Database type MSAccess - useCursorFetch - true
    Database type MSAccess - defaultFetchSize - 10

    in table output step i set Commit Size = 10

    this is the text of the error log file

    This is not a Kettle problem... it's a driver problem while outputting the rows it seems.
    Hardly anyone gets out of those besides upgrading the driver or moving to another way of accessing the database.

    i solved the crash using another DNS

    another question i have is
    the destination DB has 226 fields

    but the fields i need to insert into are just 11

    i made ModifiedJavaScript create the other fields

    but this slow down the trasformation

    it is possible to generate query with TableOutput that insert only the fields that i need?

    i cannot drop the other fields because the app needs the table as it is...

    extra columns can't be dropped yet... there's a JIRA open for it (already since a year or so).

    I'm sympathetic to this "Table Output" cause, but we just didn't find the time yet.
    Same for the "Table Input" case of doing explicit and strict tables, field names, data types and join specifications for the suspicious people among us.
