Returns or sets the value of the given object. Not available at design time and read/write at run time.
orafield.Value = data_value data_value = orafield.Value oraparameter.Value = data_value data_value = oraparameter.Value
Variant
Orafield.Value
Returns the value of the field as a Variant
.
data_value
=
orafield.Value
sets the contents of the field. Fields can contain Null
values. You can test the Value
property with the Visual Basic function IsNull()
to determine whether the value is null upon return. You can also assign Null
to the Value
property whenever the current record is editable. Field values are cached locally as the data is retrieved from the database. However, in the case of a LONG
or LONG
RAW
fields, some data may not be retrieved and stored locally. In these cases, data is retrieved as required using the methods described in the GetChunk
field method. The maximum size of a LONG
or LONG
RAW
field that can be retrieved directly through the Value
property is approximately 64 KB. You must retrieve data fields larger than 64 KB indirectly, using the GetChunk
method.
OraParameter.Value
Returns the value of the parameter as a Variant
.
data_value
= oraparameter.Value
sets the contents of the parameter. Note that changing the Variant
data type of the value can have significant impact on the processing of associated SQL and PL/SQL statements.
Note that fields of type DATE
are returned in the default Visual Basic format of "MM/DD/YY" even though the default Oracle date format is "DD-MMM-YY".
The Value
argument can be an Oracle Database 10g object, such as an OraBLOB
.
Similar to a dynaset, the object obtained from parameter Value
property always refers to the latest value of the Parameter
. The Visual Basic value Null
can also be passed as a value. The Visual Basic value EMPTY
can be used for BLOB
and CLOB
to mean an empty LOB, and for OBJECT
, VARRAY
, and NESTED
TABLE
to mean an object whose attributes are all Null
.
