Returns the Variant
type of the specified object. Not available at design time and read-only at run time.
data_type = orafield.Type data_type = oraparameter.Type data_type = oraparamarray.Type
Integer
orafield.Type
Returns the Variant
data type (see Visual Basic documentation) associated with the returned value of this field.
oraparameter.Type
Returns an integer indicating the Variant
data type that is actually bound to the SQL statement. This may differ from the Variant
data type of oraparameter.Value
, because internal conversions may be necessary to obtain a data type common to both Visual Basic and Oracle Database.

These values are located in the ORACLE_BASE\\ORACLE_HOME
\oo4o\oraconst.txt
file and are intended to match similar constants in the Visual Basic file datacons.txt
file.
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".
Note that columns defined as NUMBER
instead of NUMBER(precision
, scale)
are, by definition, floating point numbers with a precision of 38. This means that the Type
property returns a type of ORADB_TEXT
for these columns.
