TVecColumn::WriteDataset Method

Writes the contents of the Vector vector to dataset.

Writes the contents of the Vector vector to dataset. Depending on TMtxDataset::ReadWriteMode the following operation is performed:

• wmRecord => write all TVecColumn::Vector properties to current record position. The underlying dataset field must be BLOB field, otherwise an exception is raised.
• wmColumn => write TVecColumn::Vector values to dataset. If Vector is complex then each complex value is saved as real + imaginary part on two consecutive places in dataset. Dataset must have at least Vector.Length (or Vector.Length *2 if Vector is complex) records, otherwise an exception is raised. The underlying dataset field must be numeric, otherwise an exception is raised.
