  NameDescription
MoveNextUniqueMultipleKey()()()
If the cursor is not yet initialized, MoveNextUniqueMultipleKey is identical to MoveFirstMultipleKey()()(). Otherwise, move the cursor to the next non-duplicate key in the database, and store that key and associated datum and as many ensuing key/data pairs that can fit in a buffer the size of one database page in CurrentMultipleKey. MoveNextUniqueMultipleKey will return false if no non-duplicate key/data pairs exist after the cursor position in the database.
MoveNextUniqueMultipleKey(LockingInfo)
If the cursor is not yet initialized, MoveNextUniqueMultipleKey is identical to MoveFirstMultipleKey(LockingInfo). Otherwise, move the cursor to the next non-duplicate key in the database, and store that key and associated datum and as many ensuing key/data pairs that can fit in a buffer the size of one database page in CurrentMultipleKey. MoveNextUniqueMultipleKey will return false if no non-duplicate key/data pairs exist after the cursor position in the database.
MoveNextUniqueMultipleKey(Int32)
If the cursor is not yet initialized, MoveNextUniqueMultipleKey is identical to MoveFirstMultipleKey(Int32). Otherwise, move the cursor to the next non-duplicate key in the database, and store that key and associated datum and as many ensuing key/data pairs that can fit in a buffer the size of BufferSize in CurrentMultipleKey. MoveNextUniqueMultipleKey will return false if no non-duplicate key/data pairs exist after the cursor position in the database.
MoveNextUniqueMultipleKey(Int32, LockingInfo)
If the cursor is not yet initialized, MoveNextUniqueMultipleKey is identical to MoveFirstMultipleKey(Int32, LockingInfo). Otherwise, move the cursor to the next non-duplicate key in the database, and store that key and associated datum and as many ensuing key/data pairs that can fit in a buffer the size of BufferSize in CurrentMultipleKey. MoveNextUniqueMultipleKey will return false if no non-duplicate key/data pairs exist after the cursor position in the database.
