Type Property

Description

Returns the variant type of the specified object. Not available at design time and read-only at run time.

Usage

data_type = orafield.Type

data_type = oraparameter.Type

data_type = oraparamarray.Type

Remarks

orafield.Type returns the variant data type (see Visual Basic documentation) associated with the returned value of this field.

Users can expect the following mapping from Oracle internal datatypes:

Mapping From Oracle Internal Datatypes

Oracle Datatype	Constant	Value	Datatype
CHAR	ORADB_TEXT	10	String
DATE	ORADB_DATE	8	Variant
LONG	ORADB_MEMO	12	String
LONG RAW	ORADB_LONGBINARY	11	String
NUMBER (1-4,0)	ORADB_INTEGER	3	Integer
NUMBER (5-9,0)	ORADB_LONG	4	Long Integer
NUMBER (10-15,0)	ORADB_DOUBLE	7	Double
NUMBER (16-38,0)	ORADB_TEXT	10	String
NUMBER (1-15,n)	ORADB_DOUBLE	7	Double
NUMBER (16-38,n)	ORADB_TEXT	10	String
RAW	ORADB_LONGBINARY	11	String
VARCHAR2	ORADB_TEXT	10	String

These values are located in the file ORACLE_BASE\ORACLE_HOME\oo4o\oraconst.txt and are intended to match similar constants in the Visual Basic file datacons.txt.

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 the Oracle database.

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 simply as "NUMBER" instead of "NUMBER(precision, scale)" are, by definition, floating point numbers with a precision of 38. This means that the Type property will return a type of ORADB_TEXT for these columns.
