CAML Query with 10 AND conditions

Hello,
I need some help with a CAML query. This particular query needs to have 10 AND conditions. Quite frankly, with all the nesting it is driving me a little nuts:
What I have is:
<Query>
<Where>
<And>
<And>
<And>
<And>
<And>
<And>
<And>
<And>
<And>
<Eq><FieldRef Name='Column1' LookupId='TRUE' /><Value Type='Text'>10341</Value></Eq>
<Eq><FieldRef Name='Column2' LookupId='TRUE' /><Value Type='Text'>9539</Value></Eq>
</And>
<Eq><FieldRef Name='Column3' LookupId='TRUE' /><Value Type='Text'>183</Value></Eq>
</And>
<Eq><FieldRef Name='Column4' LookupId='TRUE' /><Value Type='Text'>35</Value></Eq>
</And>
<IsNull><FieldRef Name='Column5' /></IsNull>
</And>
<Eq><FieldRef Name='Column6' LookupId='TRUE' /><Value Type='Text'>4387</Value></Eq>
</And>
<Eq><FieldRef Name='Column7' LookupId='TRUE' /><Value Type='Text'>4204</Value></Eq>
</And>
<Eq><FieldRef Name='Column8' LookupId='TRUE' /><Value Type='Text'>36</Value></Eq>
</And>
<Eq><FieldRef Name='Column9' LookupId='TRUE' /><Value Type='Text'>213</Value></Eq>
</And>
<IsNull><FieldRef Name='Column10' /></IsNull>
</And>
</Where>
</Query>
I have added this into my ItemAdding Event Receiver as it will basically do a check for duplicate items based on the 10 columns.
If anyone can help guide me in this, it would be much appreciated. I have been using a CAML Query Builder to help.

Since you are not allowed to put more than two conditions in one condition group (And | Or) you have to create an extra nested group (MSDN). The expression
A AND B AND C looks like this:
<And>
A
<And>
B
C
</And>
</And>
Your SQL like sample translated to CAML (hopefully with matching XML tags ;) ):
<Where>
<And>
<Or>
<Eq>
<FieldRef Name='FirstName' />
<Value Type='Text'>John</Value>
</Eq>
<Or>
<Eq>
<FieldRef Name='LastName' />
<Value Type='Text'>John</Value>
</Eq>
<Eq>
<FieldRef Name='Profile' />
<Value Type='Text'>John</Value>
</Eq>
</Or>
</Or>
<And>
<Or>
<Eq>
<FieldRef Name='FirstName' />
<Value Type='Text'>Doe</Value>
</Eq>
<Or>
<Eq>
<FieldRef Name='LastName' />
<Value Type='Text'>Doe</Value>
</Eq>
<Eq>
<FieldRef Name='Profile' />
<Value Type='Text'>Doe</Value>
</Eq>
</Or>

Sql query with conditions and calculations???

Hi,
how I can build a query with conditions and calculations?
E.g. I've got this table
Start          | End     |     Working Place     |     Mandatory
01-JAN-13 | 11-JAN-13 |     Office           |          1
14-JAN-13 | 25-JAN-13 |     Home Office      |     0
04-MRZ-13| 15-MRZ-13 |     Office           |          0
11-FEB-13 | 22-FEB-13 |     Office           |          1
Now if column working place=Office and column mandatory=0
the new column "price" has to calculate: (End-Start)* $25.00
and if working place=Office and column mandatory=1
the "price" column has to calculate: (End-Start)* $20.60
else $0.00
I tried it with the case statement but I didn't know how
to calculate my values and display it to the virtual column "price".
Something like
case
when Working_Place = 'Office' and Mandatory=1
     then ...
else '0.00'
end as PRICE
Or is it not possible?
Edited by: DB2000 on 12.03.2013 05:09

Use CASE:
select start_dt,
        end_dt,
        working_place,
        mandatory,
        case
          when working_place = 'Office' and mandatory = 0 then (end_dt - start_dt) * 25
          when working_place = 'Office' and mandatory = 1 then (end_dt - start_dt) * 20.60
          else 0
        end price
from tbl
START_DT END_DT    WORKING_PLA MANDATORY      PRICE
01-JAN-13 11-JAN-13 Office               1        206
14-JAN-13 25-JAN-13 Home Office          0          0
04-MAR-13 15-MAR-13 Office               0        275
11-FEB-13 22-FEB-13 Office               1      226.6

The issue with using the multiple columns sub-query in WHERE clause

Hi All,
my database version is 10.2.
the problem i am trying to deal with is that when I use multiple column sub-query in the WHERE clause of the SELECT statement, the actual row number returned from the sub-query is different from the whole statement.
And what I found is that, whenever there is NULL in any of those columns returned from the SUB-QUERY, the outer query will just return NULL for that whole row.
Here is an example:
select empno, ename, job, mgr, hiredate, sal, deptno from EMP
intersect
select empno, ename, job, mgr, hiredate, sal, deptno from t;
7782     CLARK     MANAGER     7839     09-JUN-81     2450     10
7839     KING     PRESIDENT NULL 17-NOV-81     5000     10
7934     MILLER     CLERK     7782     23-JAN-82     1300     10
select * from EMP where (EMPNO, ENAME, job, MGR, HIREDATE, SAL, DEPTNO) in (
select empno, ename, job, mgr, hiredate, sal, deptno from EMP
intersect
select empno, ename, job, mgr, hiredate, sal, deptno from t);
7782     CLARK     MANAGER     7839     09-JUN-81     2450          10
7934     MILLER     CLERK     7782     23-JAN-82     1300          10     If I specifically deal with the NULL situations for the columns which might return NULL, I can get the result right.
select * from EMP where (EMPNO, ENAME, job, NVL(MGR,-1), HIREDATE, SAL, DEPTNO) in (
select empno, ename, job, nvl(mgr,-1), hiredate, sal, deptno from EMP
intersect
select empno, ename, job, nvl(mgr,-1), hiredate, sal, deptno from t);
7782     CLARK     MANAGER     7839     09-JUN-81     2450          10
7839     KING     PRESIDENT null   17-NOV-81     5000          10
7934     MILLER     CLERK     7782     23-JAN-82     1300          10     the problem is that, I feel this is a very lame way of handling it.
So, I wonder or am asking if there is any better or standard way to do it?
any help would be highly appreciated.
Thanks

Hi,
As you discovered, INTERSECT treats NULL as a value, but IN does not.
What you did with NVL is one way to handle the situation. If there was a chance that any of the columns could be NULL, then you might prefer something like this:
select      *
from      EMP
where      ( EMPNO      || '~' ||
       ENAME      || '~' ||
       job           || '~' ||
       MGR           || '~' ||
       TO_CHAR (HIREDATE, 'DD-MON-YYYY HH24:MI:SS')
                || '~' ||
       SAL           || '~' ||
       DEPTNO
     ) in (
          select EMPNO      || '~' ||
                 ENAME      || '~' ||
               job     || '~' ||
               MGR     || '~' ||
               TO_CHAR (HIREDATE, 'DD-MON-YYYY HH24:MI:SS')
                    || '~' ||
               SAL      || '~' ||
               DEPTNO
          from     emp
         intersect
          select EMPNO      || '~' ||
                 ENAME      || '~' ||
               job     || '~' ||
               MGR     || '~' ||
               TO_CHAR (HIREDATE, 'DD-MON-YYYY HH24:MI:SS')
                    || '~' ||
               SAL      || '~' ||
               DEPTNO
          from      t
         );This assumes that you can identify some string (I used '~') that never occurs in the strings in these tables.
This is implicitly converting the NUMBERs. That's usually not a good thing to do. but explicitly converting them would make this even more tedious.
You should explicitly convert any DATEs to strings, however. Depending on your default format, and your data, you might get away with implicit conversions even for DATEs, but don't bet on it.
If you had to do this often, you might consider writing a user-defined function:
delimited_string (empno, ename, job, mgr, hiredate, sal, deptno) would return a string like
'7839~KING~PRESIDENT~~17-NOV-1981~5000~10'
This will make the coding easier, but beware: it will make the execution slower.

How to write the below query with parameter and is null

Hi, I need to retrive the data if the parameter is passed on the field, else retrive all records whose field is null
Example
CREATE TABLE DEPT
       (DEPTNO NUMBER(2),
        DNAME VARCHAR2(14),
        LOC VARCHAR2(13) );
INSERT INTO DEPT VALUES (10, 'ACCOUNTING', 'NEW YORK');
INSERT INTO DEPT VALUES (20, 'RESEARCH',   'DALLAS');
insert into dept values (30, 'SALES',      'CHICAGO');
INSERT INTO DEPT VALUES (40, 'OPERATIONS', 'BOSTON');
alter table dept add(object_id number);
insert into dept values (50, 'OPERATIONS', 'BOSTON',1);
insert into dept values (60, 'OPERATIONS', 'BOSTON',1);
INSERT INTO DEPT VALUES (70, 'OPERATIONS', 'BOSTON',2);
select * from dept where object_id =:p_object_id
If i pass the object_id as 1 , it shloud retrive the values of dept with object_id 1, but if i dont pass the object_id, it should retrive all the records whose object_id is null
IF 1 is passed, as object id , it should retrive, 50, 60, if 1 is not passed as object_id it should retive 10,20,30,40
It works fine for me seperately as,
select * from dept where object_id =:p_object_id -- 1
select * from dept where object_id is null;
Is this possible to do in single query.
Thanks

SELECT *
FROM dept
WHERE object_id = :p_object_id
OR (object_id is null and :p_object_id is null)
is one approach. It's a bit verbose but the meaning is clear. If you can identify a value that would never appear in the data (-1 for example)
WHERE nvl( object_id, -1 ) = nvl(p_object_id, -1 );

Creating table with null and not null values.

I have to create a table with 5 Null nd 5 Not Null fields.My questionis which fields are place first?Not or Not Null and why???

What you mean is: the person who asked you the question thought the order of columns was important, and wanted to see if you agreed. Or maybe they were just asking the question to see whether you thought it was important (as a test of your understanding of the database).
When I started out in Oracle I was told that it was good practice to have the mandatory columns first and then the optional columns. But if you do some research you find this: the impact of column ordering on space management is: empty nullable columns at the end of the table take up zero bytes whereas empty nullable columns at the middle of the table take up one byte each. I think if that saving really is important to you you need to spring for an additional hard drive.
Besides, even if you do organise your columns as you suggest, what happens when you add an eleventh NOT NULL column to your table? It gets tacked on to the end of your table. Your whole neat organisation is blown.
What does still matter is the positioning of large VARCHAR2 columns: they should be the last columns on your table in case they create chaining. Then any query that doesn't need the large columns can be satisfied without reading the chained block, something that can't be guaranteed if you've got columns after a VARCHAR2(4000) column. This doesn't apply to CLOBs, etc. which are stored separately anyway.

Need help in optimizing the query with joins and group by clause

I am having problem in executing the query below.. it is taking lot of time. To simplify, I have added the two tables FILE_STATUS = stores the file load details and COMM table that is actual business commission table showing records successfully processed and which records were transmitted to other system. Records with status = T is trasnmitted to other system and traansactions with P is pending.
CREATE TABLE FILE_STATUS
(FILE_ID VARCHAR2(14),
FILE_NAME VARCHAR2(20),
CARR_CD VARCHAR2(5),
TOT_REC NUMBER,
TOT_SUCC NUMBER);
CREATE TABLE COMM
(SRC_FILE_ID VARCHAR2(14),
REC_ID NUMBER,
STATUS CHAR(1));
INSERT INTO FILE_STATUS VALUES ('12345678', 'CM_LIBM.TXT', 'LIBM', 5, 4);
INSERT INTO FILE_STATUS VALUES ('12345679', 'CM_HIPNT.TXT', 'HIPNT', 4, 0);
INSERT INTO COMM VALUES ('12345678', 1, 'T');
INSERT INTO COMM VALUES ('12345678', 3, 'T');
INSERT INTO COMM VALUES ('12345678', 4, 'P');
INSERT INTO COMM VALUES ('12345678', 5, 'P');
COMMIT;Here is the query that I wrote to give me the details of the file that has been loaded into the system. It reads the file status and commission table to show file name, total records loaded, total records successfully loaded to the commission table and number of records that has been finally transmitted (status=T) to other systems.
SELECT
    FS.CARR_CD
    ,FS.FILE_NAME
    ,FS.FILE_ID
    ,FS.TOT_REC
    ,FS.TOT_SUCC
    ,NVL(C.TOT_TRANS, 0) TOT_TRANS
FROM FILE_STATUS FS
LEFT JOIN
    SELECT SRC_FILE_ID, COUNT(*) TOT_TRANS
    FROM COMM
    WHERE STATUS = 'T'
    GROUP BY SRC_FILE_ID
) C ON C.SRC_FILE_ID = FS.FILE_ID
WHERE FILE_ID = '12345678';In production this query has more joins and is taking lot of time to process.. the main culprit for me is the join on COMM table to get the count of number of transactions transmitted. Please can you give me tips to optimize this query to get results faster? Do I need to remove group and use partition or something else. Please help!

I get 2 rows if I use my query with your new criteria. Did you commit the record if you are using a second connection to query? Did you remove the criteria for file_id?

ROW_NUMBER will always prevent duplicates. The ordering of the analytical function is irrelevant in your query if you use ROW_NUMBER. You can remove the outermost query and inspect the data returned by the inner query;

Problem with JDBC and VARCHAR-Columns

Hi,
i have a problem handling VARCHAR-Columns via JDBC.
I.e. by using the JDBC-components of <SunONE Community Edition Update 1> any attempt to store any other then numeric values (like "0", "01", "999" etc.) in a column of type VARCHAR results in an error.
After entering the string "test" in a JTextArea or JTextField (which is linked by its document to the VARCHAR-column) i will receive:
"java.lang.NumberFormatException: For input string: "st"/For input string: "st". I also tried the javax.sql. rowSet methods like updateString() with the same result.
Are there any knwon issues corresponding to this behaviour?

Hi Arnd,
if I understand right you are trying to insert/update value into a Varchar(1000) column. And if you set a non numeric value you get an exception "java.lang.NumberFormatException", Right?
Of course this should work with MaxDB. The exception you get doesn't come from MaxDB's JDBC driver. The driver will only throw exceptions that are derived from java.sql.Exception.
So, I guess the error comes from a layer above the JDBC layer, possibly from the JDBC-components of <SunONE Community Edition Update 1>. This would also explain why you don't see any exception in the JDBC trace.
Did you have defined any constraints for the input field (JTextArea or JTextField)?
Hope that helps.
regards,
Marco

Query with distinct and without it

Hello all,
I have a query to select some rows. like this..actually I want to show the recrods without any duplicates in voucher number and voucher type
select distinct voucher_no ,t.voucher_type
from gen_led_voucher_row_tab t
where t.company = 'IPWL'
and ((((t.debet_amount is null) and (t.currency_debet_amount IS NOT NULL and t.currency_debet_amount != 0 )))
or ((t.credit_amount is null) and (t.currency_credit_amount IS NOT NULL and t.currency_credit_amount != 0)))But someone asked from me to show some other columns in the output..so now I can't use that query..so how I show those other fields without getting duplicates in voucher_no and voucher_type. Please let me know..
Now I have to show something like this
select distinct voucher_no ,t.voucher_type ,t.voucher_date,t.credit_amount,t.debet_amount,t.currency_credit_amount,t.currency_debet_amount
from gen_led_voucher_row_tab t
where t.company = 'IPWL'
and ((((t.debet_amount is null) and (t.currency_debet_amount IS NOT NULL and t.currency_debet_amount != 0 )))
or ((t.credit_amount is null) and (t.currency_credit_amount IS NOT NULL and t.currency_credit_amount != 0)))

Tuning SQL query with SDO and Contains?

I'trying to optimize a query
with a sdo_filter and an intermedia_contains
on a 3.000.000 records table,
the query look like this
SELECT COUNT(*) FROM professionnel WHERE mdsys.sdo_filter(professionnel.coor_cart,mdsys.sdo_geometry(2003, null, null,mdsys.sdo_elem_info_array(1,1003,4),mdsys.sdo_ordinate_array(809990,2087279,778784,2087279,794387,2102882)),'querytype=window') = 'TRUE' AND professionnel.code_rubr ='12 3 30' AND CONTAINS(professionnel.Ctx,'PLOMBERIE within Nom and ( RUE within Adresse1 )',1)>0
and it takes 15s on a bi 750 pentium III with
1.5Go of memory running under 8.1.6 linux.
What can i do to improve this query time?

Hi Vincent,
We have patches for Oracle 8.1.6 Spatial
on NT and Solaris.
These patches include bug fixes and
performance enhancements.
We are in the process of making these patches
avaialble in a permanent place, but until then, I will temporarily put the patches on:
ftp://oracle-ftp.oracle.com/
Log in as anonymous and use your email for
password.
The patches are in /tmp/outgoing in:
NT816-000706.zip - NT patch
libordsdo.tar - Solaris patch
I recommend doing some analysis on
individual pieces of the query.
i.e. time the following:
1)
SELECT COUNT(*)
FROM professionnel
WHERE mdsys.sdo_filter(
professionnel.coor_cart,
mdsys.sdo_geometry(
2003, null, null,
mdsys.sdo_elem_info_array(1,1003,4),
mdsys.sdo_ordinate_array(
809990,2087279,
778784,2087279,
794387,2102882)),
'querytype=window') = 'TRUE';
2)
SELECT COUNT(*)
FROM professionnel
WHERE CONTAINS(professionnel.Ctx,
'PLOMBERIE within Nom and ( RUE within Adresse1)',1) >0;
You might want to try reorganizing the entire
query as follows (no promises).
If you contact me directly, I can try to
help to further tune the SQL.
Hope this helps. Thanks.
Dan

More Fun with NULLs and Empty Strings

Greetings,
I ran across this behavior recently and thought I'd share with the forum. I'm running 10.2.0.2. Note the difference in behavior between passing and explicit NULL in the parameter vice passing an empty string (''):
CREATE OR REPLACE PROCEDURE NULL_ES_TEST(PARAM1 IN VARCHAR2) IS
VAR1 CHAR(1);
BEGIN
IF PARAM1 IS NULL THEN
DBMS_OUTPUT.PUT_LINE('PARAM1 IS NULL');
END IF;
VAR1 := PARAM1;
IF VAR1 IS NULL THEN
DBMS_OUTPUT.PUT_LINE('VAR1 IS NULL');
ELSE
DBMS_OUTPUT.PUT_LINE('VAR1 IS NOT NULL');
END IF;
DBMS_OUTPUT.PUT_LINE('THE LENGTH OF VAR1 IS '||TO_CHAR(LENGTH(VAR1)));
END NULL_ES_TEST;
EXEC NULL_ES_TEST(PARAM1 => '');
PARAM1 IS NULL
VAR1 IS NOT NULL
THE LENGTH OF VAR1 IS 1
(var1 now holds a single space)
EXEC NULL_ES_TEST(PARAM1 => NULL);
PARAM1 IS NULL
VAR1 IS NULL
THE LENGTH OF VAR1 IS
Any Comments or Insights are welcome.
Sincerely,
Dale Ward

Well somethings not as expected (tested on 10.2.0.3)
Even if you default the parameter to '', it treats null and '' differently.

Union two tables with diffrent count of fields with null and float value

Hello,
i want to union two tables, first one with 3 fields and second one with 4 fields (diffrent count of fields).
I can add null value at end of first select but it does not work with float values in second table. Value form second table is convert to integer.
For example:
select null v1 from sessions
union
select 0.05 v1 from sessions
result is set of null and 0 value.
As workaround i can type:
select null+0.0 v1 from sessions
union
select 0.05 v1 from sessions
or simple change select's order.
Is any better/proper way to do this? Can I somehow set float field type in first select?
Best regards,
Lukasz.
WIN XP, MAXDB 7.6.03

Hi Lukasz,
in a UNION statement the first statement defines the structure (number, names and types of fields) of the resultset.
Therefore you have to define a FLOAT field in the first SELECT statement in order to avoid conversion to VARCHAR.
Be aware that NULL and 0.0 are not the same thus NULL+0.0 does not equal NULL.
In fact NULL cannot equal to any number or character value at all.
BTW: you may want to use UNION ALL to avoid the search and removal of duplicates - looks like your datasets won't contain duplicates anyhow...
Regards,
Lars
