DBPROP_IStorage
Property group: Rowset
Property set: DBPROPSET_ROWSET
Column? Y
Type: VT_BOOL
Typical R/W: R/W
Description: IStorage
If the value of this property is set to VARIANT_TRUE, the rowset is capable of manipulating the contents of columns as a storage object supporting the specified interface. The provider reports its ability to enable this property on a per-column basis by setting the flag DBPROPFLAGS_COLUMNOK. A provider that does not have the ability to turn the property on/off on a per-column basis does not set DBPROPFLAGS_COLUMNOK.
Whether or not the property is supported in the rowset as a whole or on a per-column basis, the ability to manipulate a column value as a storage object depends on whether the provider supports the coercion from the column's native type (BLOB or non-BLOB) to the particular storage interface.
