Purpose
Controls how data conversions are handled for null values.
Valid Values
0
| 1
Behavior
If set to 0
, the driver does not perform
the data type check if the value of the column is null. This allows null values to be
returned even though a conversion between the requested type and the column type is
undefined.
If set to 1
, the driver checks the data
type being requested against the data type of the table column that stores the data. If a
conversion between the requested type and column type is not defined, the driver generates
an "unsupported data conversion" exception regardless of whether the column value is
NULL.
