Returns the value of a particular element of the array at the specified index.
OraParamArray.Get_Value(array, index)
The arguments for the method are:
Arguments | Description |
---|---|
[in ] array |
A String representing the name of the array. |
[in ] index |
An Integer representing the index value of the object. |
The OraParamArray.Get_Value
method returns the value of the field as a Variant
. The value of data_value
=
oraparameter.Value
sets the contents of the parameter.
Note that fields of type DATE
are returned in the default Visual Basic format as specified in the Control Panel, 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
object. For Put_Value
, a copy of the object is made at that point in time, and Get_Value
must be accessed to obtain a new object that refers to that index value. For example, if iotype
is ORATYPE_BOTH
and an OraBLOB
object obtained from a dynaset is passed in as the input value, Get_Value
needs to be called after the SQL code has been executed to obtain the newly updated output value of the ParamaterArray
object.
Similar to a dynaset, the object obtained from the ParamaterArray
Get_Value
property refers to the latest value for that ParamaterArray
index. 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 indicate an empty LOB, and for Object
, VARRAY
, and nested table data types to indicate an object whose attributes are all Null
.
This method is not available at design time and is read-only at run time.
When binding to RAW
columns (ServerType
ORATYPE_RAW_BIN
), the value should be a byte array.
