Importing and Updating Form

(0) ShareShare
ReportReport
Posted on by fireblaster 40

Hi there, I want to write a code for importing csv file to my form and my code is working, but the problem is, I want to update the form and check whether the importing files existed or not, if its exist then the data is updated, if its not, then it will be inserted into the form. my form should be like this and the FormOne should not have the same ID appear more than once, so I would use my unique field which is the ID

0407.WhatsApp-Image-2021_2D00_07_2D00_27-at-10.48.11-AM-_2800_1_2900_.jpeg

and my code is like this 

private void importRunBaseBatch()
{
CommaTextIO textIO;
container c;
HeaderGrid HeaderGrid;
LineGrid LineGrid;
ImportRunBaseBatch importRunBaseBatch;
int i;
NoYes NoYes;
boolean first;
;

textIO = new CommaTextIo(path, "R");
textIO.inFieldDelimiter(",");
textIO.inRecordDelimiter("\r\n");

c = textIO.read();

while (textIO.status() == IO_Status::Ok)
{
if(first == false)
{
first = true;
c = textIO.read();
continue;
}

if(conLen(c) > 1)
{
HeaderGrid.clear();
HeaderGrid.FullName = conPeek(c,1);
HeaderGrid.ID = conPeek(c,2);
LineGrid.ID = conPeek(c,2);
LineGrid.Name1 = conPeek(c,3);
LineGrid.Name2 = conPeek(c,4);
HeaderGrid.insert();
LineGrid.insert();

a = HeaderGrid.ID;

}

i++;
c = textIO.read();
}
info(strFmt("%1 records imported.", i));

}

anyone has the idea how to solve this? very much thanks in advance

    conPeek() can't "undeclare" a variable. The variable must be declared before using the variable, and you also need to populate the container before you can extract anything from it with conPeek().

    You had the declaration in your original code - it was the second variable declaration inside importRunBaseBatch(). It seems that you've deleted it by mistake.

    I already tried both solution but seems it has a problem, the variable c after conPeek isn't declared, should I just put the method in the import class?

    A typical solution is implementing exist() method and checking if the record doesn't already exist:

    str id = conPeek(c,2);
if (!HeaderGrid::exist(id))
{
   ...
}

    Another approach, requiring less requests to database, is storing the information about already processed IDs in a collection:

    Set importedIds = new Set(Types::String);
str id = conPeek(c,2);

if (!importedIds.in(id))
{
	importedIds.add(id);
	...
}
