SQL statement for test conn on reserve

Hi,
We use the following statement when testing connections on reserve:
select count(*) from SYSOBJECTS
This seems rather expensive. Is there a better performing statement we can use for testing connections.
Thanks in advance.

Absolutely! This sounds like it's Sybase or MS SQLServer. Just change the
'test table' to "SQL select 1"

  • Preparing Dynamic SQL statement for inserting in Pro*C

    Hi Friends,
    From quite some time i am struggling writing Dynamic SQL statement for dynamic insert and update in Pro*C.
    Can somebody go through my code and suggest me the rigth way of doing.
    Right now it throws an error saying " Error while updating ORA-00904: invalid column name "
    Please help me.
    Girish.
    int main()
    EXEC SQL BEGIN DECLARE SECTION;
    char *uid ="scott/tiger";
    static char sqlstmt[129];
    struct /* DEPT record */
    int dept_num;
    char dept_name[15];
    char location[14];
    } dept_rec;
    EXEC SQL END DECLARE SECTION;
    EXEC SQL WHENEVER SQLERROR DO sql_error();
    EXEC SQL CONNECT :uid;
    dept_rec.dept_num = 50;
    strcpy(dept_rec.dept_name,"ADMIN");
    strcpy(dept_rec.location,"IN");
    strcpy(sqlstmt,"UPDATE dept set DNAME = dept_rec.dept_name where DEPTNO = dept_rec.dept_num");
    EXEC SQL EXECUTE IMMEDIATE:sqlstmt;
    EXEC SQL COMMIT;
    exit(0);
    void sql_error()
    printf("\nError while updating %s",sqlca.sqlerrm.sqlerrmc);
    EXEC SQL ROLLBACK;
    }

    A bit rusty here but this is how I see it.
    Think of it this way ..
    all Oracle is going to see is:
    UPDATE dept set DNAME = dept_rec.dept_name where DEPTNO = dept_rec.dept_num
    Its NOT going to know what dept_rec.dept_name is or dept_rec.dept_num is ..
    it doesnt go back and fill in those values.
    You need something like
    strcpy(sqlstmt,"UPDATE dept set DNAME = \"");
    strcat(sqlstmt,dept_rec.dept_name);
    strcat(sqlstmt,"\" where DEPTNO = ");
    strcat(sqlstmt,dept_rec.dept_num);
    printf(sqlsmt); # Just to be sure the update statement look right during testing.

    I have already gone through the Note: 948037.1. But this note is related to 11i. The solution provided in the Note is for 11i.
    I am facing this issue in R12. Is this patch applicable to R12?I belive its not. But u can check Solution part 4 for your instance, at least it can give you idea. The other note in metalink related bug and all for R11 too.

  • Problem with SQL Statement for Result Filtering

    Dear Visual Composer Experts,
    Here is another Question from me: I have a SQL Query that is working as the data service
    Select AB.AgingBandID, AB.AgingBand,
    Sum(Case when priority='Emergency' then '1' Else 0 End) as [Emergency],
    Sum(Case when priority='Ugent' then '1' Else 0 End) as Ugent,
    Sum(Case when priority='High' then '1' Else 0 End) as High,
    Sum(Case when priority='Medium' then '1' Else 0 End) as Medium,
    Sum(Case when priority='Low' then '1' Else 0 End) as Low
    from DimAgingBand AB left outer join
    (Select AgingBandID , priority , yeardesc
    from vNotifications where YearDesc = (select year(getdate())-1)) as vN
    on AB.AgingBandID=vN.AgingBandID
    where AB.AgingBandID<>'1'  
    Group by  AB.AgingBandID, AB.AgingBand
    Order by AB.AgingBandID
    That would return me a table as in the following:
         Agingband     E     U     H     M     L
         < 1week     0     0     0     0     1
         1 - 2 weeks     0     0     0     0     0
         2 - 4weeks     0     0     0     0     1
    > 1month     8     2     1     1     6
    Now that I would like to add some parameters to filter the result, so I modify the query and put it in the SQL Statement input port of the same data service. The query is like this:
         "Select AB.AgingBandID, AB.AgingBand,Sum(Case when priority='Emergency' then '1' Else 0 End) as [Emergency],Sum(Case when priority='Ugent' then '1' Else 0 End) as Ugent,Sum(Case when priority='High' then '1' Else 0 End) as High,Sum(Case when priority='Medium' then '1' Else 0 End) as Medium,Sum(Case when priority='Low' then '1' Else 0 End) as Low from DimAgingBand AB left outer join (Select AgingBandID , priority , yeardesc from vNotifications where YearDesc like '2009%' and Branch like '" & if(STORE@selectedBranch=='ALL', '%', STORE@selectedBranch) & "' and MainWorkCentre like '%') as vN on AB.AgingBandID=vN.AgingBandID where AB.AgingBandID<>'1' Group by AB.AgingBandID, AB.AgingBand Order by AB.AgingBandID"
    However this input port query keeps giving me error as NullPointerException. I have actually specified a condition where the query will run if only STORE@selectedBranch != u2018u2019.
    I have other filtering queries working but they are not as complicated query as this one. Could it be possible that query in the input port cannot handle left outer join?
    Could it be anything else?
    Help is very much appreciated.
    Thanks & Regard,
    Sarah

    Hi,
    Thank you very much for your replys. I've tested if the dynamic value of the condition is integer, it's OK
    But if the ClassID type is not integer, it's string, I write  a SQL Statement like:
    "Select DBADMIN.Class.ClassName from DBADMIN.Class where DBADMIN.Class.ClassID = '1' "
    or with dynamic condition:
    "Select DBADMIN.Class.ClassName from DBADMIN.Class where DBADMIN.Class.ClassID = '"&@ClassID&"'"
    or I write the SQL Statement for insert/update/delete data,
    I always have errors.
    I've tested if the dynamic value of the condition is integer, it's OK
    Do you know this problem ?
    Thank you very much & kindly regards,

  • Sql statement for network version of JavaDB database

    Hi,
    Could somebody please tell is it a must to have double quote for field name inside the SQL statement for JavaDB
    I am developing the project using netbean 5.5.1 IDE
    integrating netwok version of JavaDB.
    example
    select "field1","field2" from table1
    instead of the simple sql like
    select field1,field2 from table1
    I find that simple select sql query could not work without having the double quotation eclosed for any of the fieldname called by the SQL statement.
    I am not sure is it only unique to netbeans IDE environment , in principle simple plain query should work , this is however not for netbeans IDE, wht is the reason behind?
    Thanks

    The Quotes around the fieldnames are normally only needed if the field is the same as a reserved word, or has a non-standard character in the field. Look at the JavaDB/Derby manual (specifically the one with the SQL reference) to find out what the reserved words and special characters are, then redefine your table.

  • Need help on SQL Statement for UDF

    Hi,
    as I am not so familiar with SQL statements on currently selected values, I urgently need help.
    The scenario looks as follows:
    I have defined two UDFs named Subgroup1 and Subgroup2 which represent the subgroups dependent on my article groups. So for example: When the user selects article group "pianos", he only sees the specific subgroups like "new pianos" and "used pianos" in field "Subgroup1". After he has selected one of these specific values, he sees only the specific sub-subgroups in field "Subgroup2", like "used grand pianos".
    I have defined UDTs for both UDFs. The UDT for field "Subgroup1" has a UDF called "ArticleGroup" which represents the relation to the article group codes. The UDT for field "Subgroup2" has a UDF called "Subgroup1" which represents the relation to the subgroups one level higher.
    The SQL statement for the formatted search in field "Subgroup1" looks as follows:
    SELECT T0.[Name] FROM [dbo].[@B_SUBGROUP1]  T0 WHERE T0.[U_ArticleGroup]  = (SELECT $[OITM.ItmsGrpCod])
    It works fine.
    However, I cannot find the right statement for the formatted search in field "Subgroup2".
    Unfortunately this does NOT WORK:
    SELECT T0.[Name] FROM [dbo].[@B_SUBGROUP2]  T0 WHERE T0.[U_Subgroup1]  = (SELECT $[OITM.U_Subgroup1])
    I tried a lot of others that didn't work either.
    Then I tried the following one:
    SELECT T0.[Name] FROM [dbo].[@B_SUBGROUP2]  T0 WHERE T0.[U_Subgroup1] = (SELECT T1.[Code] FROM [dbo].[@B_SUBGROUP1] T1 WHERE T1.[U_ArticleGroup] = (SELECT $[OITM.ItmsGrpCod]))
    Unfortunately that only works as long as there is only one specific subgroup1 for the selected article group.
    I would be sooooo happy if there is anyone who can tell me the correct statement for my second UDF!
    Thanks so much in advance!!!!

    Please ignore the "http://" in the above statements - it is certainly not part of my SQL.
    Please also ignore the strikes.

    Hello Dear,
    Use the below queries to get the values:
    Item Sub Group on the basis of Item Group
    SELECT T0.[Name] FROM [dbo].[@SUBGROUP]  T0 WHERE T0.[U_GroupCod] =$[OITM.ItmsGrpCod]
    Item Sub Group 1 on the basis of item sub group
    SELECT T0.[Name] FROM [dbo].[@SUBGROUP1]  T0 WHERE T0.[U_SubGrpCod]=(SELECT T0.[Code] FROM [dbo].[@SUBGROUP]  T0 WHERE T0.[Name] =$[OITM.U_ItmsSubgrp])
    Sub group 2 on the basis of sub group 1
    SELECT T0.[Name] FROM [dbo].[@SUBGROUP2]  T0 WHERE T0.[U_SubGrpCod1]=(SELECT T0.[Code] FROM [dbo].[@SUBGROUP1]  T0 WHERE T0.[Name] =$[OITM.U_ItmsSubgrp1])
    this will help you.

    How can get a database like ****.SQL file for test in sqlplus in oracle8i,I am a beginner,thanks

    I'll give it a guess as to what it is you want but I'm afraid you'll have to give some more information to go on. I appreciate it's difficult for people who are beginners or who don't have English as their first language.
    Are you trying to run a SQL file? From SQL*plus you can do either of these:
    SQL> start my_file
    or
    SQL> @my_file
    N.B.: if th efile has a .sql extension you don't need to include it, but you do for any other file extension e.g.
    SQL> @myfile.run

  • SQL statement for calculating performance targets

    Hi
    I have taken of the admin of a database which stores project goals and scores. I have to develop a way to calculate how well all projects meet these scores. The table concerned is called goal and looks like this:
    goal
    goal_name
    project_code
    current_value
    good_value
    bad_value
    This can be for many different goals, for example if a project wants to get up a goal of having no more than 5 bugs in the project. I can also set a bad value, say 20, so if any projects have 20 or more bugs, triggers or alerts can be sent So I can enter into this table. The reason for putting 5 for good not 20 is because these scores are to be realistic.
    project_code = foo
    goal_name = software bugs
    good_value = 5
    bad_value = 20
    However, some goals may have the values switched and be in a much higher range, or may even be a percentage. For example one for number of sales could be
    project_code = foo
    goal_name = software sales
    good_value = 200
    bad_value = 50
    or project delay
    project_code = foo
    goal_name = sproject delay
    good_value = 0%
    bad_value = 50%
    i am trying to develop a SQL statement so I can get a % score of how well a goal is performing, so I can see
    What is the goal % for all foo goals
    Or what is the goal % for goal 'software sales'
    And also more importantly, how well are the goals doing globally.
    The requirement for doing this is using a single SQL statement, well, one SQL statement for the requirements I listed above, so for example the semantics are
    SELECT average(goal perforance) WHERE .... project = foo .... or goal = software sales... etc
    I am having trouble doing this, I have been banging my head against mydesk all day. the biggest thing is thowing me off is that the good value can be higher or lower than the bad value, and I am having trouble visualizing how to but this conditional statement in SQL
    One more thing, the percentage returned should never be more than 0% or 100%.
    If anyone has any ideas or pointers, please help me out,
    Thanks for your time,

    SQLI haven't looked at your requirements in detail cos I don't have time for such cumbersome tasks. However, you could have two UNION'd select statements, one which caters for the good > bad and one which caters for the good < bad. Also and alternative would be the use of DECODE or CASE statements in your select which are good for switching things around based on conditions.
