1. remove-duplicates, delete-duplicates
- www.franz.com
- 23 remove-duplicates, delete-duplicates.
- Syntax: remove-duplicates sequence &key from-end test test-not start end key.
- delete-duplicates sequence &key from-end test test-not start end key.
- Description: remove-duplicates returns a modified copy of sequence from which any element that matches another element occurring in sequence has been removed. ...
- delete-duplicates is like remove-duplicates, but delete-duplicates may modify sequence. ...
- remove-duplicates and delete-duplicates return a sequence of the same type as sequence with enough elements removed so that no two of the remaining elements match. ...
- remove-duplicates returns a sequence that may share with sequence or may be identical to sequence if no elements need to be removed. ...
- delete-duplicates, when sequence is a list, is permitted to setf any part, car or cdr, of the top-level list structure in that sequence. When sequence is a vector, delete-duplicates is permitted to change the dimensions of the vector and to slide its elements into new positions without permuting them to produce the resulting vector. ...
- Examples: (remove-duplicates "aBcDAbCd" :test #'char-equal :from-end t) "aBcD" (remove-duplicates '(a b c b d d e)) (A C B D E) (remove-duplicates '(a b c b d d e) :from-end t) (A B C D E) (remove-duplicates '((foo #\a) (bar #\%) (baz #\A)) :test #'char-equal :key #'cadr) ((BAR #\%) (BAZ #\A)) (remove-duplicates '((foo #\a) (bar #\%) (baz #\A)) :test #'char-equal :key #'cadr :from-end t) ((FOO #\a) (BAR #\%)) (setq tester (list 0 1 2 3 4 5 6)) (delete-duplicates tester :key #'oddp :start 1 :end 6) (0 4 5 6) .
- Side Effects: delete-duplicates might destructively modify sequence. ...
2. DUPLICATES Clause (duplicates_clause) (SAP Library - MySQL MaxDB Library)
- dev.mysql.com
- DUPLICATES Clause (duplicates_clause) .
- The DUPLICATES clause (duplicates_clause) can be used to determine how key collisions are handled.
- <duplicates_clause> ::= REJECT DUPLICATES | IGNORE DUPLICATES | UPDATE DUPLICATES.
- The DUPLICATES clause is used in the SQL statements CREATE TABLE statement and INSERT statement.
- REJECT DUPLICATES or no DUPLICATES clause.
- IGNORE DUPLICATES.
- UPDATE DUPLICATES.
- REJECT DUPLICATES or no DUPLICATES clause.
- IGNORE DUPLICATES.
- UPDATE DUPLICATES.
- If, for an INSERT statement with UPDATE DUPLICATES and a QUERY expression, there is more than one key collision for the same key, it is impossible to predict the content of the respective base table row once the INSERT statement has been completed.
- If, for an INSERT statement with IGNORE DUPLICATES and a QUERY expression, more than one row in the result table supplies the same base table key, and if this key did not exist before in the base table, it is impossible to predict which row will be inserted in the table.
- If the table name specified in the INSERT statement identifies a table without a user-defined key, the DUPLICATES clause has no effect.

- SQL statements in which the DUPLICATES clause is used.
- REJECT DUPLICATES or no DUPLICATES clause.
- IGNORE DUPLICATES.
- UPDATE DUPLICATES.
- REJECT DUPLICATES or no DUPLICATES clause.
- IGNORE DUPLICATES.
- UPDATE DUPLICATES.
- If there is more than one key collision for the same key for an INSERT statement with UPDATE DUPLICATES and QUERY expression specification, it is impossible to predict the content of the respective base table row once the INSERT statement has been completed.
- If, for an INSERT statement with IGNORE DUPLICATES and a QUERY expression, more than one row in the result table produces the same base table key, and if this key did not exist before in the base table, it is impossible to predict the row that will be inserted in the table.
- If the table name specified in the INSERT statement identifies a table without a user-defined key, the DUPLICATES clause has no effect.

8. Duplicates Processing
- www.nodc.noaa.gov
- Such a procedure results in needing to identify and remove duplicates. ...
- If these fields are the same then the two reports being tested are considered to be potential duplicates. ... If the times are within 15 minutes and the positions are within 5 km, then the two reports are considered to be potential duplicates.
- In order to perform these tests for duplicate observations on a file of ocean station data, it is necessary to bring platform identification, date-time, and position information on potential duplicates together in computer memory at the same time. To accomplish this the input data must be arranged in some convenient order so that potential duplicates will not be separated by several thousand observations in the input file. ...
- C Common storage area and declarations for ring buffer used in the C duplicates identification C COMMON/RING/KMSG_NO(500),KCALL(500),KDATE(500), + KTIME(500),KLAT(500),KLONG(500) C CHARACTER*10 KCALL,KDATE*8,KTIME*4 C REAL*4 KLAT,KLONG C .
- If either of the tests indicate a potential duplication between the two observations, then the value of KMSG_NO for that message is added to a list of observations that are potential duplicates of the target observation. This process results in the development of a list of potential duplicates within a 15 minute window forward of the target observation.
- Once the list of potential duplicates has been established for the 15 minute window, processing continues with a second look at each observation with respect to the target observation. This second look is for the purpose of deciding whether the "potential" duplicates identified in the first pass are in fact real duplicates. It can be considered to be an analysis for the purpose of removing entries from the duplicates list. If, for example, the target and the potential duplicate are within the fuzzy area-fuzzy time window but the subsurface information is completely different for the two stations, then the observations are not duplicates and the subsequent observation should be removed from the list. In the algorithm the methodology is always to identify duplicates of the target message that are equal or forward in time of the target message. ...
- There are two tests that are used to remove potential duplicates from the list. ... If the potential duplicates have been identified through a coincidence of the platform-date-time information and the positions are outside the 5 km window, then the subsequent observation is removed from the duplicates list. ...
- The input file to the duplicates identification system has therefore been organized as a random access file using the Indexed Sequential Access Method (ISAM) supported by the DEC Alpha OpenVMS operating system. ...

- www.sleepycat.com
- FAQ - How can I custom sort secondary duplicates?.
- If you have a secondary database with sorted duplicates configured, you may wish to sort the duplicates according to some other field in the primary record. Let's say your secondary key is F1 and you have another field in your primary record, F2, that you wish to use for ordering duplicates. You would like to use F1 as your secondary key, with duplicates ordered by F2.
- When duplicates are allowed in a secondary, the duplicate comparison function simply compares those primary key values. ...
- In general it is not intended to provide a way to order keys or duplicates using record data that is not present in the key or duplicate entry. ...
- When you query the duplicates for F1, sort them manually by F2 after you query them. ...
- - Option #2 requires enough memory to sort all duplicates for a given key F1.
