jamel / dbf Goto Github PK

Would it be possible to use this lib to read DBC (compressed DBF) files?

Hey,
I have used this library
i m getting this error
Caused by: org.jamel.dbf.exception.DbfException: Unsupported Dbf field type: 20
Can you help me to resolve this error?

Thanks

The README.md section 'Build from sources' you mentioned

...
./grablew clean build

when it should be

...
./gradlew clean build

Return null when i tried to read memo field, is not supported? How can i read it?

I am getting error unsupported Dbf field type: 32

Hi,

the read API looks really great 👍 and I would love to use it, but I also need a write API.

Any plans to implement such a functionality?
I would do it myself, if I won't be on a tight schedule

Thanks anyways,
Chris

It is giving issue
Unsupported Dbf field type: 0
Unsupported Dbf field type: 45

Could you please suggest what could be the issue? and is there any way forward.

any fix ??

The field names is init with system charset, need use default charset of DbfReader

There are empty values in Date column in file I am trying to parse, your (in other cases very helpful library) is parsing them as some "extreme Date value" with year 17793. Is it possible to update library to parse them as null, which, I think, is expected meaning? File I am parsing can be downloaded from https://liehweb.financnasprava.sk/data/export/cisOLDDBF.zip in this zip it is Subjekt2.dbf file. This code snipet should reproduce it (first expected null value is in first record).

File file = new File("src/test/resources/Subjekt2.dbf");
        try (DbfReader reader = new DbfReader(file)) {

            Object[] row;
            while ((row = reader.nextRecord()) != null) {
                Date expectedNullDate = ((Date) row[11]); // <- extreme date parsed here
                if(17000 < expectedNullDate.getYear()){ //workaround
                    expectedNullDate = null;
                }
            }
        }

Don't hurry, my workaround is OK for some time ;-)

I updated the getFieldLength() method in DbfField class with the following to fix.

public int getFieldLength() {
if (dataType == 'C' && decimalCount > 0) {
return fieldLength + (256 * decimalCount);
}
return fieldLength;
}

Hi,

When I'm reading a dbf with a record marked to be deleted it raises and error.

DbfReader reader = new DbfReader(new File("path_to_some_dbf_file"));
Object[] row;
int count = 1;
while ((row = reader.nextRecord()) != null) {
}

The error appears in reader.nextRecord() ( the line 58 of my class )

Hi,

Would be good to have ResultSet-like API for DbfReader with ability to get fields by column names, e.g.

DbfRow row;
while ((row = reader.nextDbfRow()) != null) {
    totalSum += row.getDouble("BalanceUSD");
}
