Select count(*) statement in ABAP

Hi,
Im writing following statement in my Function module,
select count(*) into l_count
from user_master
where username = l_username and
      process_type = processtype and
      password = oldpassword.
And there is one entry in table user_master.
But still, I'm getting l_count as zero..
Can somebody help me with this.
Regards,
Amey

select count(*) into l_count
from user_master
where username = l_username and
process_type = processtype and
password = oldpassword.
Use group by option...
Like this....
select count(*) into l_count
from user_master
where username = l_username and
process_type = processtype and
password = oldpassword group by username.

    In fact, if you use count(1) then the optimizer actually re-writes that internally as count(*).
    Count(*) and Count(1) are have identical executions.

  • What's wrong with my SELECT/COUNT(*) statement?

    I am trying to get a total count of records related to a single master record within one table, and if I test this in the DW recordset wizard, I get the results I need. By testing it, I mean if I enter something other than the default -1, where there are results related to another 'master record', then I end up with the correct amount of rows, but when I test it in a browser, all I am getting is '0' for all records.
    This bit of code is setting the 'master record ID' to which others will relate to:
    <?php $_GET['trcount'] = $row_rs_replycount['fld_fID'] ?>
    This is my recordset which is inline with the code which is inside a repeat region:
    <?php
    $threadreplys_rs_replycount = "3";
    if (isset($_GET['trcount'])) {
      $threadreplys_rs_replycount = $_GET['trcount'];
    mysql_select_db($database_conn_mrs, $conn_mrs);
    $query_rs_replycount = sprintf("SELECT *, COUNT(*) AS countTOT FROM tbl_forumPOSTS WHERE fld_fTHREADID = %s ORDER BY fld_fID DESC", GetSQLValueString($threadreplys_rs_replycount, "int"));
    $rs_replycount = mysql_query($query_rs_replycount, $conn_mrs) or die(mysql_error());
    $row_rs_replycount = mysql_fetch_assoc($rs_replycount);
    $totalRows_rs_replycount = mysql_num_rows($rs_replycount);
    ?>                       
    And this is the code to display the total number of records that are related
    <?php echo $row_rs_replycount['countTOT']; ?>
    As I say, I have it working when testing different default values in the recordset wizard, but not live on a page.
    Thanks.

    >"SELECT *, COUNT(*) AS countTOT FROM tbl_forumPOSTS WHERE....
    That SQL is not valid - at least not by SQL standards. If your query contains an aggregate, then all columns that are not aggregated must be in a group by clause. It's possible that MySQL implicitly adds all non-aggreated columns to a group by, but you should probably fix it anyway. If you don't need to use the other columns from that table in the recordset, then just remove the * from the select list.
    "SELECT COUNT(*) AS countTOT FROM tbl_forumPOSTS WHERE....
    If you still have a problem, then output the value in $totalRows_rs_replycount to see if you are getting any rows returned from your query.
    Next, comment out these lines:
    if (isset($_GET['trcount'])) {
      $threadreplys_rs_replycount = $_GET['trcount'];
    to make sure any value in trcount is not interfering with the default value of '3' and see if that returns any results.

  • How to determine package size dynamically for select - endselect statement in ABAP

    Hi All,
    I was using select- edselect with package size but i have hard coding the package size. Can any one tell me the the process to determine dynamic package size so that i can use in parallel processing.

    Hi,
    If you are looking to determine or set the value of package size dynamically then use below code for reference.
    DATA: itab TYPE TABLE OF spfli,
           wa like LINE OF itab,
           n    TYPE i.
    n = 10.
    SELECT carrid connid
    FROM   spfli
    INTO   CORRESPONDING FIELDS OF TABLE itab
    PACKAGE SIZE n.
       LOOP AT itab INTO wa.
         WRITE: / wa-carrid, wa-connid.
       ENDLOOP.
    ENDSELECT.
    If you are concerned about the performance then either use SELECT with OPEN CURSOR and CLOSE CURSOR.
    Let me know if it helped?

  • Select Count(*) from... returns zero, select * from... returns 4000 recs?

    Hi,
    I have an odd situation where "select count(*) from my_view where some_clause" returns 0, but the exact same query fetching the data (ie "select * from my_view where some_clause") works fine and fetches, correctly, 4000+ records.
    I have tried dropping and recreating the view, and collecting DB stats again, but the problem persists.
    I had a look at the explain plans and they are very different, but both the SQL statements work fine on a copy of the database taken with impdp.
    Does anyone have any suggestions on what might be going on here ?
    Any help would be appreciated, I've run out of ideas !

    Maybe it's the bug that a function based index is present and gets incorrectly used in the select count(*) statement?
    If that's not the case, then please show us more details, like the statement and both execution plans.

  • Select count(*) on sql statement returning zero when a matching row exists.

    Our account has an ANSI C application that checks for the existence a row on an Oracle table(s) by using the following SQL:
    int iCount = 0;
    EXEC SQL
    SELECT count(rownum) INTO :iCount
    FROM sys.all_tab_columns
    WHERE table_name IN
    (SELECT table_name FROM
    sys.all_synonyms
    WHERE upper(synonym_name) = upper(:szDestTable))
    AND upper(column_name) = upper(:szColumnName)
    AND owner = 'DBAUSER';
    The bind variables szDestTable and szColumnName are populated with values parsed from columns on another database table. This application is executed through out the day. Occasionally, the application will report a zero in the iCount when there should be a match. I have verified the szDestTable and szColumnName are populated with the correct values which would find a match and they are correct. To make matters even stranger, the application will parse the same input values and find a match (as it should). At some point during the day, and it can be at any time, the application will NOT find a match on the same file, same values. Every subsequent execution of this application will not find a match on the same values. Once the database is brought down and started up in the evening for its normal backups, the application will find a match again on the same values. This problem does not occur every day. I could be a week or a week and a half between incidents.
    I printed the contents of the sqlca.sqqlerrm.sqlerrmc field to a log file. The sqlca.sqlerrm.sqlerrmc field reported an ORA-1405 bind variable was null when the iCount was reporting a zero. When I compiled this application, I set the Proc*C flag to UNSAFE_NULLS=yes since there are other bind variable in the application that can be NULL and that is ok.
    The above SQL is compiled into the C application using the Proc*C compiler. It is compiled using the Oracle 11.2.0.2 libraries. The application is executed against an Oracle 11.2.0.2 database. The database and application are executed on an HP/Unix 11.31 platform.
    This problem did not start occurring until our account went from Oracle 10.2 to Oracle 11.2. Recently, I have changed the SQL to perform a “SELECT COUNT(rownum)” instead of the “SELECT COUNT(*)”. I compiled the application and executed the new application with the SELECT COUNT(rownum) against the same database where the same application with the SELECT COUNT(*) was failing to find a row that actually existed. The application with the SELECT COUNT(rownum) found the matching row as it should have. The new application has been executing in production for about 10 days now without any problems against ten various Oracle 11.2 databases.
    Why would SELECT COUNT(*) and SELECT COUNT(rownum) be any different?

  • "select count(*)" and "select single *" returns different result

    Good day!
    product version SAP ECC 6.0
    oracle10
    data transfers from external oracle db into customer tables using direct oracle db link
    sometimes I get case with different results from 2 statements
    *mytable has 10 rows
    *1st statement
    data: cnt type I value 0.
    select count( * ) into cnt from mytable WHERE myfield_0 = 123 and myfield_1 = '123'.

    *sy-subrc returns 4 - incorrect, 10 rows are "invisible"
    but
    1. se16 shows correct row number
    2. I update just one row from "invisible" rows using se16 and 2nd statement returns correct result after that
    can not understand why
    thank you in advance.

    Thank you, Vishal
    but,
    general problem is that
    1. both statements have the same WHERE conditions
    2. 1st return resultset with data (sy-dbcnt=10), 2nd return empty dataset, but must return 1 in sy-dbcnt
    Yes, different meaning, you are right, but must 2nd must return 1, because of "select single *" construction, not 0.
    Dataset to process is the same, WHERE conditions are equal...
    I think the problem is that how ABAP interperets select count(*) and "select single *".
    Maybe "select count (*)" scans only PK from index page(s)? and "select single *" scans data pages? and something is wrong with that?
    I'm new in SAP and didn't find any SAP tool to trace dump of data and indexes pages with Native SQL.
    se16 shows all records.
    And why after simple manual update of just one record using se16 "select single *" returns 1?
    I've just marked one row to update, didn't change any data, then pressed "save".

  • Select count * is not working

    Hi everybody.
    I've got a very strange problem, when i'm doing a select count* the result is giving me a value that is not the maximum (but when i check the database table the maximum value is another..)
    Could it be that the select command is not executing against the table, rather than the SAP cache??
    If this is the case, how can i avoid this?? I mean force the select command to execute against de DB table.
    thanks a lot.

    to get max value of a table u can use
    Select max( fld )............
    Bypassing the SAP buffer with the above additions is a means to increase the performance when accessing buffered database tables. To explicitly bypass the SAP buffer in the SELECT statement, always use the addition BYPASSING BUFFER instead of the implicit behavior of the additions stated above.

  • Using SELECT INTO statement to transfer data from one DB to another?

    Hello,
    I need to move data from an SAP table to another downstream SQL server box without flat file in between. I have set up the DBCON interface, so that my ABAP code on SAP can connect to the remote SQL Server, then I can run INSERT command as Native SQL inside the ABAP.
    However, INSERT has performance problem. The best performer as I can find is SELECT INTO statement. But then I am stuck at how to use SELECT INTO to query my local SAP table and send (via INTO) to remote database. I am not even sure whether I should use Open SQL or Native SQL.
    Any suggestion? BTW, I understand the limitation of Native SQL, but we are OK to use it.
    Thanks!

    It appears that this is some kind of migration project due to the scope of the data contained in the single file? If so whatever you do is like ly to be trow away once the migration of data is completed.
    You have a couple of options:
    1) Get the data extracted from HFM in multiple files instead of one bulk file, broken down by scanario,year & period
    2) Take the single data dump file produced by FDM and manipulate it yourself to get the data in a more usuable format for processing through FDM.
    Option 2 could be achieved via any ETL tool or a custom file parsing script. What may be more attractive to you and allow you to fully leverage your investment in FDM is that you could use the PULL adapter that ships as part of the FDM adapter suite to perform this transformation exercise. The PULL adapter takes a flat file input and allows you to use all the in built functionality of FDM to transform it and output a modified flat file (or series of flat files). You could use it to produce multioload files or a series of files broken down by scenario,year,period.
    Whatever you do I would suggest that break the single data file down into smaller chunks as this will help with the iterative debugging process you will inevitably have to undetake whislt migrating the data to the new application.

    That 418 seconds - not the hours you reported earlier. Is it possible that your connection to the database broke ?
    On a typical system, by the way, you can usually turn one direct read for tablescan into 1MB, so your scan seems to have covered about 59 GB, which seems to be in the right sort of ballpark for 130M rows.
    we have another query and when we test the query execution using v$sql, is_bind_sensitive =N, how to make is_bind_sensitive=Y all the time.. There is a hint /*+ bind_aware */ - I'd have to check whether or not it's documented at present. It might help.
    I would be interested in hearing why you think the hint should be bind sensitive when the optimizer doesn't.

       AND pha.type_lookup_code = 'CONTRACT'
       AND pha.org_id IN(7041, 7042);The above query runs quicky (approx. 1 second). If I take out the AND pha.vendor_id = 98 then the query takes a few minutes to run.
    When I try to export it, or scroll down to view > 500 rows, TOAD crashes.
    I know this isn't a TOAD forum, but I think that this is probably an issue with my no doubt rubbish SQL.
    If I take out this sub-select, then the problem doesn't happen:

               AND pla.contract_id = pha.po_header_id) po_countHowever, I can't work out a better way of getting the data I need.
    The sub-select counts POs which have been raised where the contractID on the PO line is the same as the PO Header ID from the main query.
    Any advice please, on what I could do to sort this out would be much appreciated.

       AND pha.org_id           IN (7041, 7042);Aside from the sub-query (which is entirely new), the query above is just what you posted, with 2 lines changed and 2 lines added, as marked.
    This should be more efficient, but I don't know for certain that it will solve the Toad problem.
    I hope this answers your question.
    If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables, and also post the results you want from that data.
    It never hurts to say what version of Oracle you're using.

  • Alternative for select count('x') or count(*)

    Hi Gurus,
    I need to use select count(*) multiple times in a SP before and after deletion of rows from multiple tables. As this is an expensive method, do we have some alternative for Count(*), like selecting something from a system table or view instead?

    Hi
    You can know the number of rows affected by the DELETE statement in PL/SQL (if you are using PL/SQL) using sql%rowcount. So you don't really need to count the rows again after the delete took place...
    If you are deleting the same rows as selected by the second count condition (older than a particular date), in fact you only need to count rows once for each table.

  • Select count of sum

    Hi
    Need help with getting a count of different sums:
    Table: Stay
    Columns: Name, Nights
    each name can have multiple rows with different number of nights, now I have a select looking like this:
    select sum(nights),name from stay
    group by name
    The result could look something like this:
    1 smith
    2 miller
    1 grant
    1 simpson
    2 sharp
    How do I do to get a count on the sum(night)? Is it possible in the same query?

    If you want to count how many distinct records appear in your current select statement (i.e. 5 in this case), you can do
    SELECT count(*) num_distinct_guests,
           total_nights,
           name
    FROM (
      SELECT sum(nights) total_nights,
             name
        FROM stay
      GROUP BY name
    )If you want the total number of stays, in addition to the total time stayed, use something like
    SELECT sum(nights),
           name,
           count(nights)
      FROM stay
      GROUP BY name;Justin
