Diffrence b/w select single & select upto one row

hi
wat is the diffrence b/w select single & select upto one row?

Hi,
Select single has to be used with a where condition that has all the key fields:
It will always return a unique record(If a match is found).
Select upto 1 rows would get your the first record if multiple matches are found.
and select up to has to be end with endselect statements.
According to SAP Performance course the SELECT UP TO 1 ROWS is faster than SELECT SINGLE because you are not using all the primary key fields.
select single is a construct designed to read database records with primary key. In the absence of the primary key, it might end up doing a sequential search, whereas the select up to 1 rows may assume that there is no primary key supplied and will try to find most suitable index.
The best way to find out is through sql trace or runtime analysis.
Use "select up to 1 rows" only if you are sure that all the records returned will have the same value for the field(s) you are interested in. If not, you will be reading only the first record which matches the criteria, but may be the second or the third record has the value you are looking for.
The System test result showed that the variant Single * takes less time than Up to 1 rows as there is an additional level for COUNT STOP KEY for SELECT ENDSELECT UP TO 1 ROWS.
The 'SELECT SINGLE' statement selects the first row in the database that it finds that fulfils the 'WHERE' clause If this results in multiple records then only the first one will be returned and therefore may not be unique.
Mainly: to read data from
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.
Mainly: to check if entries exist.
When you say SELECT SINGLE, it means that you are expecting only one row to be present in the database for the condition you're going to specify in the WHERE clause. so that means, you will have to specify the primary key in your WHERE clause. Otherwise you get a warning.
SELECT UP TO 1 ROWS is used in cases where you just want to make sure that there is at least one entry in the database table which satisfies your WHERE clause. Generally, it is meant to be used for existence-check.
You may not want to really use the values returned by the SELECT statement in this case (thought this may not necessarily be so).And in each case the database optimizer may choose a different strategy to retrieve the data.
Knowing when to use SELECT SINGLE or SELECT ... UP TO 1 ROWS
A lot of people use the SELECT SINGLE statement to check for the existence of a value in a database. Other people prefer to use the 'UP TO 1 ROWS' variant of the SELECT statement.
So what's the difference between using 'SELECT SINGLE' statement as against a 'SELECT .... UP TO 1 ROWS' statement ?
If you're considering the statements
SELECT SINGLE field INTO w_field FROM table.
and
SELECT field INTO w_field FROM table UP TO 1 ROWS. ENDSELECT.
then looking at the result, not much apart from the extra ENDSELECT statement. Look at the run time and memory usage and they may be worlds apart.
Why is this ?? The answer is simple.
The 'SELECT SINGLE' statement selects the first row in the database that it finds that fulfils the 'WHERE' clause If this results in multiple records then only the first one will be returned and therefore may not be unique.
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.
According to SAP Performance course the SELECT UP TO 1 ROWS is faster than SELECT SINGLE because you are not using all the primary key fields.

Select Single is the best one compared to UPto one rows.
Select Single will get the first record from the table which satisfies the given condition.So it will interact once with the database.
UTO 1 rows will get the list of the records for the given match and iwll show the first record from the list.So it will take time to get the record.
SELECT SINGLE VBELN from VBAK
where MATNR = '1M20'.
---Thjis will get the first matched record and will display the record
SELECT VBELN from VBAK
where MATNR = '1M20' upto 1 rows.
---Thjis will get the list of matched records and will display the first record
The Major difference between Select Single and Select UPTO 1 rows is The Usage Of Buffer for each.
Select Single will search for all the satisfied data and bring all that data into Buffer and later it will give to that data to the program.
Select UPTO 1 Rows will end the search after getting the 1st satisfied record and gives that record to the program.
Thus Select Single will take much processing time when compare with Select UPTO 1 rows.

Select single vs select upto one rows only by experts

Hello Experts,
I am sorry to post this thread again , it is million times answered.
There is a lot of confusion in the answers, so we want a very clear and justifiable answer.
please dont post rubish answers by simply copying and pasting from other threads .
now i will give an example of 2 threads which i seen in the forum.
1) first thread is like this....
According to SAP Performance course the SELECT UP TO 1 ROWS is faster than SELECT SINGLE because you are not using all the primary key fields.
Select single is a construct designed to read database records with primary key. In the absence of the primary key, it might end up doing a sequential search, whereas the select up to 1 rows may assume that there is no primary key supplied and will try to find most suitable index.
2)second post is like this....
When it comes to performance..select ..up to 1 rows is faster than select single....
why?
B'coz, during a select single, the query always hits the database and reads the entire table into memory and fetches the matching single record for you in the memory,
where as in the case of select up to 1 rows, the query goes to the memory first if found it retrieves the record from there, otherwise the query hits the database.
3)i seen an simple example in se30 in tips and tricks it shown select single is having better performance than select upto...rows,
We all really value the best answers..

hi this is the standard one from the sdn..which will clear the answer..

1) It retrieves only one row
2) It does not need an ENDSELECT statement
3) THE FULL KEY OF THE TABLE MUST BE INCLUDED IN
THE WHERE CLAUSE OF THE SELECT STATEMENT
to say in simple
SELECT SINGLE:
1. Select single is based on PRIMARY KEY
2. It will take the first record directly without searching of all relevant records.(Though you have lot of records for given condition)
SELECT UPTO 1 ROW :
It will check all records for given condition and take the first record .
It means in select single no searching, where as other searching.
Therefore, select single more efficient than UPTO 1 ROW.

Tree selection (single selection model) but on 2 panels

hi..
here is my problem..
I have 2 trees each with single selection mode.
i add them to 2 scrollpanes and add these 2 scrollpanes to a split pane and divided them vertically.
When i select the tree node in the upper pane the corresponding node is displayed as the root of the tree in lower pane, so far so fine.
when i select the tree node in the lower pane the tree which was already selected in the upper pane is deselected. while i want that selection to remain..
help me to solve this..
thanx in advance..
K�vi

you can only have 1 focused component, but trees shouldn't lose selection just cuz they lose focus.... unless you have a custom cell renderer for the tree and you are using the wrong options to paint the cell selection with.

Select single column but multiple rows in JTable

Hi
I have a jTable and want to be able to select multiple rows but only in a single column.
I've set these properties which makes selection almost the way I would like it.
table1.setCellSelectionEnabled(true);
table1.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);the only problem now is that the user can select multiple columns.
Is there a simple way to restrict selection to single column?
regards
abq

table.setCellSelectionEnabled(true);
table.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);
DefaultListSelectionModel model =
(DefaultListSelectionModel)table.getColumnModel().getSelectionModel();
