Returns a comma-separated list of key fields
for a buffer.
Data type: CHARACTER
Access: Read-only
Applies
to:
Buffer object handle, Data-source object handle
For a data-source object buffer, this attribute
returns a comma-separated list of key fields defined in an associated
KEYS clause for the specified buffer. If there are no defined key
fields, this attribute returns a comma-separated list of key fields
in the buffer's unique primary index (if any). If there are no defined key
fields and no unique primary index, this attribute returns the string "ROWID".
Syntax
Following is the syntax for accessing this attribute for a data-source object buffer:
data-source-handle:KEYS ( buffer-sequence-number )
|
-
data-source-handle
- The handle to the data-source object.
-
buffer-sequence-number
- An integer that represents the sequence number of a buffer in the list of buffers for
the data-source object. Specify buffer-sequence-number to identify a
buffer in the data-source object when the data-source object is defined against more
than one database table buffer.
Note: Sequence numbers for buffers of a
query start at one, where one represents the top level and subsequent numbers
represent lower levels of a join, if any.
Syntax
Following is the syntax for accessing this attribute for a buffer directly:
-
buffer-handle
- The handle to the buffer.
