Regarding open sql

what is diff between OPEN SQL & NATIVE SQL

SQL is implemented difference depending on the database, this is native SQL, SAP wants to provide an abstraction from this, so that the developer does not have to worry about what DB is running underneath, he can just write the SQL statement and it will run on any machine regardless of DB.  This is OPEN SQL. This is the SQL statements that you use in your ABAP programs. 
You can use Native SQL in your programs as well, but you must know about the underlying DB.

  • Case Insensitive search and "IN" Clause - Open SQL

    Hi,
    I have some doubts regarding Open SQL:
    Is there any support for Case Insensitive Search in Open SQL, is it availabe by default?
    Is there any restriction on number of elements in "IN" Clause, in Open SQL, is there any default number?

    When you are querying any strings, it is always case sensitive.
    Is there any restriction on number of elements in "IN" Clause, in Open SQL, is there any default number?
    I don't think there area any. IN opearator works like combined ORs and here you don't have any restrictions in fields number.

    > I have some doubts regarding Open SQL:
    I believe that you've questions and not doubts...
    > - Is there any support for Case Insensitive Search in Open SQL, is it availabe by default?
    Nope, there is nothing like that. By default all supported database use a bytewise equal operator - case insensitivness needs to be programmed by hand.
    E.G. using UPPER(x)/LOWER(x) functions.
    Be aware that this disables the possibilities of index usage.
    > - Is there any restriction on number of elements in "IN" Clause, in Open SQL, is there any default number?
    Yes, there is a restriction and it differes between the different DBMS.
    Until recently you could have 2000 variables per statement with MaxDB.
    The current versions of DBSL and MaxDB Kernel now support up to 10000 variables per statement.
    Anyhow, in most cases, such a long in list can and should be avoided by using the FOR ALL ENTRIES construct. With this, the DBSL automatically splits the long IN list into smaller chunks and executes the statements several times.
    This is invisible to the ABAP report - it just gets the result set as usual.

    I guess in anyone of the DB forums is Ok.

  • ABAP/4 Open SQL statement with WHERE ... LIKE and pattern too long

    Dear All,
    I am getting an error "ABAP/4 Open SQL statement with WHERE ... LIKE and pattern too long" while executing the following statement:
    CLEAR LS_RANGE.
    LS_RANGE-SIGN     = 'I'
    +LS_RANGE-OPTION     = 'CP'     +
    LS_RANGE-LOW     = 'S_ADMI_FCD'
    LS_RANGE-HIGH     = 'S_ADMI_FCD'
    COLLECT LS_RANGE INTO LT_RANGE.
    SELECT *
               FROM UST12
               INTO CORRESPONDING FIELDS OF TABLE LT_OBJECT_VALUES
               WHERE FIELD IN LT_RANGE
               AND AKTPS   = 'A'.
    For options like BT(Between), EQ(Equal) in range table, this above query is executing without dump. But for option CP, it simply dumps & in dump what i found is, it is concatenating the value in low & high.
    Does anyone have any idea regarding open sql using range tables.
    Thanks,
    Bhupinder

    Hi,
    I commented as follows:
    If  LS_RANGE-HIGH is empty, you can use EQ, NE, GT, LE, LT,CP, and NP. These operators are the same as those that are used for logical expressions. Yet operators CP and NP do not have the full functional scope they have in normal logical expressions. They are only allowed if wildcards ( '*' or '+' ) are used in the input fields. If wildcards are entered on the selection screen, the system automatically uses the operator CP.
    If  LS_RANGE-HIGH  is filled, you can use BT (BeTween) and NB (Not Between). These operators correspond to BETWEEN and NOT BETWEEN that you use when you check if a field belongs to a range. You cannot use wildcard characters.
    You can try:
    CLEAR LS_RANGE.
    LS_RANGE-SIGN = 'I'.
    +LS_RANGE-OPTION = 'CP' +
    LS_RANGE-LOW = 'S_ADMI_FCD'.
    LS_RANGE-HIGH = 'S_ADMI_FCD'.
    FIND '*' IN LS_RANGE.
    IF sy-subrc = 0.
      LS_RANGE-OPTION = 'CP'.
    ELSE.
      LS_RANGE-OPTION = 'EQ'.
    ENDIF.
    COLLECT LS_RANGE INTO LT_RANGE.
    SELECT *
    FROM UST12
    INTO CORRESPONDING FIELDS OF TABLE LT_OBJECT_VALUES
    WHERE FIELD IN LT_RANGE
    AND AKTPS = 'A'.
    If you use wildcards the LS_RANGE  length should not exceed 10 characters.
    Hope this information is help to you.

  • Performance: Open SQL vs. Native SQL (Oracle)

    Hi everybody,
    I have an interesting issue here. For a DB selection I use an Open SQL query from a table view into an internal table. It works fine, but the performance is not very well. The SELECT uses LIKE and wildcards (%) to search for customer master data (names and address fields).
    Because of the bad performance I made some tests in transaction DB02 with native SQL, but exactly the same SELECT structure. It looks like this:
      SELECT *
        FROM zzrm_cust_s_hlp
       WHERE client = 100
         AND mc_name1      LIKE '<name>%'
         AND mc_name2      LIKE '<name>%'
         AND valid_from    <= <timestamp>
         AND valid_to      >= <timestamp>
    Ok, now I tried exactly the same SELECT statement with the same data to search for (<name> and <timestamp) with Open SQL and Native SQL. The Difference is quite suprising, the Native SQL query is about 5-10 times faster (arount 1 sec) than the Open SQL query (around 5-10 sec). Even with the LIKE keywords and the wildcards.
    Any ideas what could be the problem with the Open SQL query?
    And: what can I do to achive the same performance as with the Native SQL query?
    Kind regards and thanks in advance for any help,
    Matthias

    Ok, here is the the SQL explaination from the DB02 query:

    Of course I can see the difference.
    But since the statements are identical, I don't understand why this difference exists

  • OPEN SQL performance question

    Hi friends,
    I'm going to read and process data in an interface coded in ABAP and OPEN SQL. To improve efficiency and reliability I'm processing the data in packets of a fixed size of rows - reading rows up to a predetermined numer into an internal table which then is processed and then finaly written back to database followed by "commit work". Then the process will continue with reading the next fixed number of rows, process them, and so on ...
    The general question is, which is the most efficient way to implement this scenario?
    I think of two basic approaches:
    1.1) Loop over results from a cursor using FETCH NEXT CURSOR inside a LOOP appending the lines to the internal table.
    2.1) Execute SELECT ... INTO TABLE <itab> FROM <table> UP TO <data packet size> ROWS.
    My assumtion is that approach 2 would be the more effecient, is that correct?
    The processed data will be written back to the database in one single statement:
    2.2) INSERT <table> FROM TABLE <itab>
    Which I assume is more efficient than doing the same using multiple inserts within a loop?
    Regards,
    Christian

    In native SQL you can also use the packet options.
    SELECT  <Fields name>      appending corresponding fields of table <Internal table>
                <b>package size 20000</b>
                FROM <Database table name>
                WHERE <Condition>.
    ENDSELECT.
    By using this the system will fetch the records from database table in packets [20000 records per package]

  • Hi experts, how to use open sql to read data from one " maintenance view"?

    i want to use this part of data within report ,so how to use open sql statement to read data from one " maintenance view"?

    Hi
    You can't use OPEN SQl statements to fetch data from maintenance view
    You have to use only Database views
    see the different types of views and the difference
    The followings are different types of views:
    - Database View (SE11)
    Database views are implement an inner join, that is, only records of the primary table (selected via the join operation) for which the corresponding records of the secondary tables also exist are fetched. Inconsistencies between primary and secondary table could, therefore, lead to a reduced selection set.
    In database views, the join conditions can be formulated using equality relationships between any base fields. In the other types of view, they must be taken from existing foreign keys. That is, tables can only be collected in a maintenance or help view if they are linked to one another via foreign keys.
    - Help View ( SE54)
    Help views are used to output additional information when the online help system is called.
    When the F4 button is pressed for a screen field, a check is first made on whether a matchcode is defined for this field. If this is not the case, the help view is displayed in which the check table of the field is the primary table. Thus, for each table no more than one help view can be created, that is, a table can only be primary table in at most one help view.
    - Projection View
    Projection views are used to suppress or mask certain fields in a table (projection), thus minimizing the number of interfaces. This means that only the data that is actually required is exchanged when the database is accessed.
    A projection view can draw upon only one table. Selection conditions cannot be specified for projection views.
    - Maintenance View ( SE54 )
    Maintenance views enable a business-oriented approach to looking at data, while at the same time, making it possible to maintain the data involved. Data from several tables can be summarized in a maintenance view and maintained collectively via this view. That is, the data is entered via the view and then distributed to the underlying tables by the system.
    Please have a look at below link. It will help you.

  • How to get different field in two are more different table using open sql

    Dear all,
              This SenthilMani am very new into sap abap am having doubt in reports how get the different fields from different tables like mara,marc,mard using open sql and native sql program give me some tips to get the data .
    with regards,
    senthil

    HI ,
      1) If u want to select data from more the two table then u can use FOR ALL ENTRIES.
             EX ..Open sql
                       select matnr from mara into table t_mara.
                      select matnr werks from marc into table t_marc for all entries in t_mara where matnr = t_mara-matnr.
      2) U can join more than one table.
               ex:
                   select mara~matnr
                              marc~werks
                    from mara join marc into table t_maramarc
                     on maramatnr = marcmatnr
    3) Using  native sql  ...only u can use JOIN statement

  • The column name "PERNR" has two meanings. ABAP/4 Open SQL statement.

    Hi All,
    Could anyone advise on what are the error I encountered at below code.
    I get the error in " The column name "PERNR" has two meanings. ABAP/4 Open SQL statement." . This errors happen to all the key fields I have selected in below code (eg: pernr, subty, objps, sprps, begda, endda, seqnr).
    The field zeih also encountered error in "Unknown column name "ZEIH". not determined until runtime, you cannot specify a field list."      
      SELECT  pernr
                   subty
                   objps
                   sprps
                   begda
                   endda
                  seqnr
                  zlsch
                  ZEIH
      SELECT * INTO CORRESPONDING FIELDS
              OF TABLE  i_pa0009
              FROM pa0001 INNER JOIN pa0009
              ON pa0001pernr = pa0009pernr
              WHERE bukrs IN s_code AND
              banks NE space.

    Hi,
    In this query
    SELECT pernr
    subty
    objps
    sprps
    begda
    endda
    seqnr
    zlsch
    ZEIH
    if you have used joins and if both the database pa0001, pa0009 has the above mentioned fields you will get the error message as the control gets confused as to which table of the field you are referring to..., instead use them in this way
    SELECT pa0001~pernr
    for each field mention to which table it belongs and ~ before the field name in the above fashion, this will remove the error

  • Open Sql Insert

    Hi Friends!
       Using insert can we use direct to insert record in database table its possibe whats the syntax.

    Hi Rahul,
    1. INSERT INTO  dbtab      VALUES wa. oder
    INSERT INTO (dbtabname) VALUES wa. oder
    INSERT  dbtab      FROM wa. oder
    INSERT (dbtabname) FROM wa.
    2. INSERT  dbtab      FROM TABLE itab. oder
    INSERT (dbtabname) FROM TABLE itab.
    3. INSERT  dbtab. oder
    INSERT *dbtab.
    Effect
    Inserts new lines in a database table (see relational database). You can specify the name of the database table either in the program itself in the form dbtab or at runtime as the contents of the variable dbtabname. In both cases, the database table must be defined in the ABAP Dictionary. By default, data is only inserted in the current client. Data can only be inserted using a view if the view refers to a single table and was defined in the ABAP Dictionary with the maintenance status "No restriction".
    INSERT belongs to the Open SQL command set.
    In some cases, the syntax rules that apply to Unicode programs are different than those for non-Unicode programs.See Open SQL and Unicode.
    Notes
    You cannot insert a line if a line with the same primary key already exists or if a UNIQUE index already has a line with identical key field values (with regard to this UNIQUE index).
    When inserting lines using a view, all fields of the
    database table that are not in the view are set to their initial value
    (see TABLES) - if they were defined with NOT NULL in the ABAP Dictionary. Otherwise they are set to NULL.
    Authorization checks (see The SAP Authorization Concept) are not supported by the INSERT statement. You must include these in the program yourself.
    Lines specified with the INSERT command are not finally added to the database table until after a database commit (see Logical Unit of Work (LUW)). Prior to this, you can cancel any changes to the database with a database rollback (see Programming Transactions).
    In the dialog system, you cannot rely on the locking mechanism used by the database system (see Database Locking) to synchronize simultaneous access to the same database by several users. Therefore, it is often necessary to use SAP's locking mechanism (see SAP Locking).

  • Adding columns in a open sql select query

    Hi Everyone,
    I would like to add the values of n columns of a table and place them in one column, how can i achieve this in open sql.
    In oracle native sql the query will look like this:
    Select col1 + col2 + col3 AS col
    from tab1;
    On a similar grounds, i would like to concatenate the contents of n columns into one column. The oracle native sql will look like this:
    select col1 || col2 || col3
    from tab1;
    How can I do this in Open SQL.
    Thanks in advance.
    Prabhu.

    Hi Prabhu,
    I'm afraid what you're trying to do is not possible using the Open SQL. You will have to get the data from all the three columns into an internal table and then write your own logic to accomplish the same.
    data : begin of itab occurs 0,
             col1 type i,
             col2 type i,
             col3 type i,
             col4 type i,
           end of itab.
    field-symbols: <fs_itab> like line of itab.
    SELECT COL1
           COL2
