    Hi, I try to update the record "2" of a table callled "test" with the UpdateRecord and UpdatedRecord2,

    I can add new records with

    DBUtils.InsertMaps(SQL1, "test", ListOfMaps) and this Add a new record.

    I try to update record with:

    For i = 0 To 150 -1
    If i <= 150 Then

            Mapa_Datos.Put((Num_campo&Num_campo2), edt_R(i).text)
            fields_list.Put((Num_campo&Num_campo2), edt_R(i).text)
    End If

    "test", ListOfFields, ListOfMaps)
    I'm using it wrong, but I dont understand what is wrong.

    Why do you check that i <= 150? It will always be true.

    UpdateRecord and UpdateRecord2 update a single record. Do you want do update multiple records?

    Because I don't know how do that!. I make that "for" to get 151 fields from the 1 record.
    And I see that cost a lot of power performance(152 queries..).

    I have a database with 152 fields, and I need to get the 151 fields in an array.
    Then I read the 152 fields from the record1, next I get the record2...

    My experience with databases is very limited, and maybe I'm using it wrong.

    In the table I save 152 questions and the next record are the answers.
    I accept suggestions if I'm making it wrong.

    And I'm using a similar code to put info in the db.

    Then I'm going to change to field "Questions" and other Fields "Answers".

    Sorry, but I don't understand your database structure. I'm not sure that your structure is the best one.
    What columns do you have in the table ?
    Can you explain it more in detail.

    Hi Klaus at the moment I have 152 Columns, then in the record 1 (id=1) they are questions I need to show to the user.
    And on the record 2, 3, 4, 5, 6, 7, 8.. I save the answers.
    And with the info from record id=2 I generate a PDF.

    Do I understand well ? You use 151 columns in record 1, but you use only 1 column with the answer in the next records ?
    Why don't you use two columns one with the questions and the second one with the answers.
    Each record has a question with its answer.
    Or am I missing something ?
