Type Property
Sets or returns a value that indicates the operational type or data type of an object.
Settings and Return Values
The setting or return value is a constant that indicates an operational or data type. For a Field or Property object, this property is read/write until the object is appended to a collection or to another object, after which it's read-only. For a QueryDef, Recordset, or Workspace object, the property setting is read-only. For a Parameter object in a Microsoft Jet workspace the property is read-only, while in an ODBCDirect workspace the property is always read-write.
For a Field, Parameter, or Property object, the possible settings and return values are described in the following table.
| Constant | Description | ||
| dbBigInt | Big Integer | ||
| dbBinary | Binary | ||
| dbBoolean | Boolean | ||
| dbByte | Byte | ||
| dbChar | Char | ||
| dbCurrency | Currency | ||
| dbDate | Date/Time | ||
| dbDecimal | Decimal | ||
| dbDouble | Double | ||
| dbFloat | Float | ||
| dbGUID | GUID | ||
| dbInteger | Integer | ||
| dbLong | Long | ||
| dbLongBinary | Long Binary (OLE Object) | ||
| dbMemo | Memo | ||
| dbNumeric | Numeric | ||
| dbSingle | Single | ||
| dbText | Text | ||
| dbTime | Time | ||
| dbTimeStamp | Time Stamp | ||
| dbVarBinary | VarBinary | ||
For a QueryDef object, the possible settings and return values are shown in the following table.
| Constant | Query type | |
| dbQAction | Action | |
| dbQAppend | Append | |
| dbQCompound | [email protected] | |
| dbQCrosstab | Crosstab | |
| dbQDDL | Data-definition | |
| dbQDelete | Delete | |
| dbQMakeTable | Make-table | |
| dbQProcedure | Procedure (ODBCDirect workspaces only) | |
| dbQSelect | Select | |
| dbQSetOperation | Union | |
| dbQSPTBulk | Used with dbQSQLPassThrough to specify a query that doesn't return records (Microsoft Jet workspaces only). | |
| dbQSQLPassThrough | Pass-through (Microsoft Jet workspaces only) | |
| dbQUpdate | Update | |
Note To create an SQL pass-through query in a Microsoft Jet workspace, you don't need to explicitly set the Type property to dbQSQLPassThrough. The Microsoft Jet database engine automatically sets this when you create a QueryDef object and set the Connect property.
For a Recordset object, the possible settings and return values are as follows.
| Constant | Recordset type |
| dbOpenTable | Table (Microsoft Jet workspaces only) |
| dbOpenDynamic | Dynamic (ODBCDirect workspaces only) |
| dbOpenDynaset | Dynaset |
| dbOpenSnapshot | Snapshot |
| dbOpenForwardOnly | Forward-only |
For a Workspace object, the possible settings and return values are as follows.
| Constant | Workspace type |
| dbUseJet | The Workspace is connected to the Microsoft Jet database engine. |
| dbUseODBC | The Workspace is connected to an ODBC data source. |
Remarks
When you append a new Field, Parameter, or Property object to the collection of an Index, QueryDef, Recordset, or TableDef object, an error occurs if the underlying database doesn't support the data type specified for the new object.
