Examples of SQLLongint

org.apache.derby.iapi.types.SQLLongint

SQLLongint satisfies the DataValueDescriptor interfaces (i.e., OrderableDataType). It implements a bigint column, e.g. for * storing a column value; it can be specified when constructed to not allow nulls. Nullability cannot be changed after construction, as it affects the storage size and mechanism.

Because OrderableDataType is a subtype of DataType, SQLLongint can play a role in either a DataType/Row or a OrderableDataType/Row, interchangeably.

We assume the store has a flag for nullness of the value, and simply return a 0-length array for the stored form when the value is null.

PERFORMANCE: There are likely alot of performance improvements possible for this implementation -- it new's Long more than it probably wants to.

      null, 0, null, null, 0);


    // Create the template for the index. This method "knows" that
    // all rows in the base table have one IntCol
    T_AccessRow template = new T_AccessRow(2);
    SQLLongint col0 = new SQLLongint(0);
    RowLocation col1 = sc.newRowLocationTemplate();
    template.setCol(0, col0);
    template.setCol(1, col1);


    DataValueDescriptor[] baseRow = new DataValueDescriptor[1];
