How to add field column name to dataset in C#

HDF5 Library
12

It seems that there is an issue with the VariableTransientRegister method. As a workaround, please use the VariableRegister method instead like the following:

public class HDFqlExample
{
    public static void Main(string []args)
    {

        int[,] values = new int[100, 2];
        int number;

        number = HDFql.VariableRegister(values);

        for (int i = 0; i < 100; i++)
        {
            values[i, 0] = i;
            values[i, 1] = 100 - i;
        }

        for (int iIndex = 0; iIndex < 15; iIndex++)
        {
            string sFileName = "painters" + iIndex.ToString() + ".h5";

            HDFql.Execute("CREATE FILE " + sFileName);

            HDFql.Execute("USE FILE " + sFileName);

            HDFql.Execute("CREATE GROUP picasso ORDER TRACKED");

            HDFql.Execute("CREATE ATTRIBUTE picasso/subject AS UTF8 VARCHAR VALUES(\"Les Demoiselles d'Avignon\")");

            HDFql.Execute("CREATE DATASET picasso/guernica AS COMPOUND(X_column AS INT, Y_column AS INT)(100) VALUES FROM MEMORY " + number);

            HDFql.Execute("CREATE ATTRIBUTE picasso/guernica/subject AS UTF8 VARCHAR VALUES(\"guerra civil española\")");

            HDFql.Execute("CLOSE FILE");
        }

        HDFql.VariableUnregister(values);

    }
}

FYI, we will release a new version of HDFql containing a fix for this issue as soon as the HDF5 library version 1.8.22 is released - which should happen still this year.
