Multiple WHERE query

Is it possible to use WHERE more than once in a query?
eg.
stmt.executeUpdate("UPDATE Audit " + "SET Log_Off_Time = '" + hourValue + ":" + minuteValue + "' WHERE Username = '" + getUserName() + "' & WHERE Log_Off_Time = 0");

Also, as was implied but never stated in the post above, you do not need to repeat your WHERE, just simply string the ANDs together...
SELECT * FROM <table> WHERE <fieldA> = 'foo' AND <fieldB> = 'bar' AND ...

"Invalid Column" on multiple where clauses with subqueries and cfqueryparam

I'm seeing a behavior in the coldfusion cfquery that I'd like to find an exmplanation for . I've got a query that does a subquery in the select portion and if I have multiple where lines, I get an "invalid column name" message for my second where clause, but only when I'm using cfqueryparam
For example on the following I get "Invalid column name 'position_id'"
SELECT   department_staff_tbl.*,
         (   SELECT   max(bookmark_id)
             FROM     bookmarked_items_tbl
             WHERE    item_id = department_staff_tbl.staff_id
         ) AS bookmark_id
FROM     department_staff_tbl
WHERE    department_id = <cfqueryparam value="#arguments.deptid#" cfsqltype="cf_sql_integer">
AND     position_id   = <cfqueryparam value="#arguments.posid#"   cfsqltype="cf_sql_integer">
AND     staff_id      = <cfqueryparam value="#arguments.staffid#" cfsqltype="cf_sql_integer">
If I change the order of my where clause so staff_id is first, then it tells me "department_id" is an invalid column.
If I only have one where clause, it works. (i.e. WHERE position_id = <cfqueryparam value="#arguments.posid#" cfsqltype="cf_sql_integer">).
If I remove the where clause from my subquery (WHERE     item_id = department_staff_tbl.staff_id) it works.
It also works if I remove the cfqueryparam from my where clause so that my query looks like this:
SELECT   department_staff_tbl.*,
         (   SELECT   max(bookmark_id)
             FROM     bookmarked_items_tbl
             WHERE    item_id = department_staff_tbl.staff_id
         ) AS bookmark_id
FROM     department_staff_tbl
WHERE    department_id = #arguments.deptid#
AND     position_id   = #arguments.posid#
AND     staff_id      = #arguments.staffid#
Any thoughts?

I see two tables. So can the server. So, use qualified column-names.
SELECT   department_staff_tbl.*,
         (   SELECT   max(bookmarked_items_tbl.bookmark_id)
             FROM     bookmarked_items_tbl
             WHERE    bookmarked_items_tbl.item_id = department_staff_tbl.staff_id
         ) AS bookmark_id
FROM     department_staff_tbl
WHERE    department_staff_tbl.department_id = <cfqueryparam value="#arguments.deptid#" cfsqltype="cf_sql_integer">
AND      department_staff_tbl.position_id   = <cfqueryparam value="#arguments.posid#"   cfsqltype="cf_sql_integer">
AND      department_staff_tbl.staff_id      = <cfqueryparam value="#arguments.staffid#" cfsqltype="cf_sql_integer">

How to combine insert and where query ?

hi..
could somebody guide me how to combine insert and where query ?
insert into tdc_imarspc (ANUMBER,EMF_ID,PRODUCT) values ('1234567','65','ITFS')
where anumber not like '1234567';
Thank you,
Baharin

Hi, Baharin,
As Mahesh said, WHERE only works on a query.
You can always base a query on dual, like this:
INSERT INTO
tdc_imarspc (ANUMBER,     EMF_ID,     PRODUCT)
SELECT          '1234567',     '65',     'ITFS'
FROM         dual
WHERE          anumber      NOT LIKE '1234567';Of course, you can use a literal, like '1234567' in both places where I used the bind variable, but if you're not using a variable, why would you want to?
You could also put all the literals in a sub-query (based on dual), and reference column names in the main WHERE clause, LIKE THIS:
INSERT INTO
tdc_imarspc (     ANUMBER,     EMF_ID,          PRODUCT)
WITH     sub_q
AS (
    SELECT    '1234567' AS an,     '65' AS ei,     'ITFS' AS pr
    FROM      dual
SELECT          an,          ei,          pr
FROM     sub_q
WHERE      an      NOT LIKE '1234567';
I assume you're not really saying
an      NOT LIKE '1234567'If you're not using any wild cards after LIKE, you might as well use !=
an      != '1234567'

Join and Multiple where clauses: which is better??

There was an argument between a colleague and I. He prefers building his views joining many tables with many where clause while I am cute with my join which is simpler and more understandable for me. So, it started an argument on which is a superior way of joining tables.
I will actually like to know we is faster and better: using JOINs or using multiple where clauses to retrieve values from multiple tables.?

Dave:
"Are we talking about the difference between Oracle Joins and ANSI Joins?
e.g.
Select d.dept_name, e.emp_name
from dept d, emp e
where d.dept_id = e.dept_id"
That is not really an "Oracle Join". That syntax works on just about every SQL database I have ever worked with. The (+) syntax for an outer join is Oracle specific, but some other databases use a similar style for outer joins (something like a.c += b.c or a.c *= b.c).
OP:
There are things you can do with the ANSI style syntax that either cannot be done, or cannot be done as easily, with Oracle's syntax. Most notably, outer joining one table to more than one other tables, and FULL OUTER joins.
Having said that, in my experience, both are rather rare occurrences, so I tend to stick to doing the jopins in the WHERE clause because that is what I am used to.

you will have a stroke before you hit 40That's not the point, but thanks for your concern and you'll probably end up having a stroke sooner than me if you keep asking questions this way ;)
Point is: stick to your original thread/question, keep it all together, be complete, instead of reposting and starting all over again.
It's confusing when you start a new thread, while the context of your old thread matters.
While Blu seemed to be correct, you changed the question in your previous thread after his answer and started a new one, with the same 'data'.
Hence me being a 'nit-picker', because by starting multiple threads:
- you'll get the right answer slower, maybe much slower
- we're assuming things that might be out of context, given your previous thread
etc.

Is Query of Queries faster than multiple WHERE criteria?

If I need a recordset based on two table column fields (let's say firstName and lastName), is it better to run one query with a WHERE firstName = x AND lastName = y, or is it better to query of queries and find all records with a specified firstName, and then query that query to filter only records with a specified last name? Which is the better/faster method?
<cfquery name="somequery" datasource="someds">
SELECT *
FROM sometable
WHERE firstName = 'John' AND lastName = 'Smith'
</cfquery>
or....
<cfquery name="somequery" datasource="someds">
SELECT *
FROM sometable
WHERE firstName = 'John'
</cfquery>
<cfquery name="somequery2" dbtype="query">
SELECT *
FROM somequery
WHERE lastName = 'Smith'
</cfquery>

As a rule of thumb, make the database server do all the work... i.e. locally. If what you are interested is "first name = x and last name = y," then those are the only records that you want to be "sent over the little wire" to you. "The little wire" is always the bottleneck.

Query with multiple where

Hello,
I am trying to get query using LINQ to DocumentDB and have some issues.
This code works fine (example from https://code.msdn.microsoft.com/Azure-DocumentDB-NET-Code-6b3da8af/sourcecode?fileId=132409&pathId=296733303
var ee = client.CreateDocumentQuery<dynamic>(

"FROM Families f " +
"JOIN c IN f.Children " +
"JOIN p IN c.Pets " +
"WHERE p.GivenName = 'Fluffy'");
And converted version also OK
var ff = client.CreateDocumentQuery<Family>(colSelfLink)
.SelectMany(family => family.Children
.SelectMany(children => children.Pets
.Where(pets => pets.GivenName == "Fluffy")
.Select(pets => new
family = family.Id,
child = children.FirstName,
pet = pets.GivenName
But what if I want to add some condition on the "Family"
var ee = client.CreateDocumentQuery<dynamic>(
colSelfLink,

"FROM Families f " +
"JOIN c IN f.Children " +

Help me with returing multiple rows - Query

I am trying to return multiple rows and i need help with my query.
and most important of all one of the requirement is the following:

Thanks in advance

If you define your service_level as a table then it will be much easier.
with service_level
as
select 'ALL' parent_lvl, 'Sergeant' srv_lvl from dual union all
select 'ALL', 'Bonus I' from dual union all
select 'ALL', 'Deputy Bailiff' from dual union all
select 'ALL', 'Deputy Lockup' from dual union all
select 'ALL', 'Deputy Bailiff Security' from dual union all
select 'ALL', 'Custody Assistant' from dual union all
select 'ALL', 'Security Officer' from dual union all
select 'ALL', 'Security Assistant' from dual union all
select 'ALL', 'Security Officer and Security Assistant' from dual union all
select 'ALL', 'Private Security' from dual union all
select 'All Deputies', 'Deputy Bailiff' srv_lvl from dual union all
select 'All Deputies', 'Deputy Bailiff Security' from dual union all
select 'All Deputies', 'Deputy Lockup' from dual union all
select 'All Sworn', 'Sergeant' srv_lvl from dual union all
select 'All Sworn','Bonus I' from dual union all
select 'All Sworn','All Deputies' from dual union all
select 'All Sworn','Deputy Bailiff' from dual union all
select 'All Sworn','Deputy Lockup' from dual union all
select 'All Sworn','Deputy Bailiff Security' from dual
select *
from in_service
where rank IN (
          select srv_lvl
            from service_level
           where upper(parent_lvl) = upper(:SL)
              or upper(srv_lvl) = upper(:SL)

Multiple Table Query

Hey All!
It's been a while since I last posted a message in these
forums. But it looks like I need your help again.
So here is the problem:
I have to create a list of the companies' projects, yet to
compile the complete list I have to query 4 tables, with a one to
many and many to many relation ship.
Here is what I have so far.
the main table is the projects table, hence I start with
that. Right now I can query the table, plus the companies table
that each project is linked to. Also, each project may have a link
to multiple companies, so I normalized the data by creating a
companies link table:
SELECT projects.project_id, project.project_name,
compproj_link.company_id
/* I only get the company id and convert it to an actual
name when I output */
FROM projects LEFT JOIN compproj_link ON
compproj_link.project_id = projects.project_id
/* here I also filter to get only active projects */
WHERE project.status in(1,2)
/* I group by the project id since there might be several
companies linked to a specific project */
GROUP BY projects.project_id, project.project_name,
compproj_link.company_id
ORDER BY project_name
This works perfectly fine when I output with the group
attribute, but now I have to link another table... called the
airdates. The reason is that I want to order my list by the
contents of this table (which may or may not be present)...
this airdates that is linked to my projects is structured
like so:
airdates
airdates_id - auto num
project_id - the project it is linked to hence could be
linked to many projects
then there are the actual air dates
airdateslist
airdateslist_id auto num
airdates_id - since for each air date record could be
multiple dates
airdate_date - date field
airdate_backupdate - another date field
airdate_current - this is a yes/no, and specifies whether
this date is most current.
Hence, by doing two more LEFT OUTER JOINS in my main query
would work fine, BUT I need to get the most current date from the
airdateslist that is set for a particular project. and when I do
this I get no records because as of yet, no project has an airdate
that is current.
So my question is if I can somehow add those airdates tables
to my main query, and be able to sort by the current date, IF it is
present, and if not, still have all my projects displayed?
PS. I think I have confused myself even more when writing
this out, so if you have any questions please write. Thank you in
advance!
Vega...

First, this:
* I group by the project id since there might be several
companies linked to a specific project */
GROUP BY projects.project_id, project.project_name,
compproj_link.company_id
doesn't accomplish anything.
Second, when I read what you posted about the two airdates
tables, I'm not convinced that the table structure achieves what
the comments and fieldnames describe as the objective.
You say none of your projects have a current airdate. Do
these tables have any data at all? If not, it's going to be hard to
write a query when you can't ensure you got the correct
results.

Multiple where conditions in one parameter

Hi,
Is it possible to have more than one where condition in one parameter?
For example, my WHERE_CLAUSE parameter holds the value "where id='12345' and name='john smith'"
when i run the report, I get a [052008_033528064][][EXCEPTION] java.lang.NullPointerException at oracle.apps.xdo.dataengine.DataTemplateParser.getObjectVlaue(Unknown
Source) Thus the sql statement did not execute.
But if I change the WHERE_CLAUSE to "where id='12345'" or "where name='john smith'" it works fine.
My observation is that if there are two where conditions, BI publisher wont allow it. Am I correct?
But the report has to be open to the possibility of having more than one where clause condition. Is there a work around for this?
Thanks,
Shanak

nope your mistaken. bip will handle multiple joins.
1. make sure the where_clause parameter is defined in your package.
2. make sure use & syntax
3. make sure your sql is not malformed. This is probably the issue.
4. also, read my article on bind variables. the practice of coding the actual value in a where clause should be avoided at all costs. Causes the query execution plan to be reparsed each time that particular query is executed.

Multiple count query

I'm trying to write a function to compare two different counts.
I have patient on multiple drugs...some drugs are allergy drugs and at least one allergy drug must be marked as primary.
select count(drug_role) as vAllergyCount, count(primary_flag) as PF, ap.patient_id
from ae_all_drugs aed, ae_patient ap
where drug_role = 'Allergy'
and aed.patient_id = ap.patient_id
and ap.patient_id like '2012%'
group by ap.patient_id,primary_flag
order by ap.patient_id
when grouped by patient id and primary flag I would receive a record like this:
VAlllergyCount | PF | patient_id
1 | 0 | 2012AB1
3 | 1 | 2012AB1
If i only group by patient_id I get this (which is what I want):
VAlllergyCount | PF| patient_id
4 | 1 | 2012AB1
But if I try to compare the two:
IF vAllergyCount > 1 and PF = 1 THEN 'SUCCESS' ELSIF 'FAIL'
I receive the error message "exact fetch returns more than requested number of rows" becuase the results are really my first query.
Can anyone help me re-write my query to compare the values?
P.S. I'm very new to this and this forum and I apologize for not inserting code tags. I don't know how.

I need to write a function because the SQL query is going to be used as an edit check for another program. So yes, it will have to worth my time.
You are correct. I have a patient on multiple drugs. I want to know if there is at least one allergy drug (drug_role) > 1 if there is at least ONE primary allergy drug.
I did initially write my function with the patient_id as an input value. Why would I not need the vAllergyCount or the pf if that is an argument?If all you want to know is 'SUCCESS' or 'FAIL', then write a query that produces 'SUCCESS' or 'FAIL'. Inside the query, it may be handy to have something like vAllergyCount or pf, but that doesn't mean that they will be returned by the query, or that you need PL/SQL variables for them.
Here's my original function:That's a PROCEDURE, not a function. Sometimes, people use the word "procedure" lossely, to mean any kind of stored code, including functions, but never the other way around.
\Don't forget to put another \ tag at the end of the formatted section.
\ tags are supposed to occur in pairs. If you have an odd number of \ tags, the last one has no effect, and is displayed as regular text.
PROCEDURE COUNT_ALLERGY_MED (
     ivPatient_ID IN VARCHAR2,
     ovErrorText          OUT     VARCHAR2 )
IS
     vCase_ID          VARCHAR2 (25);
     vSusCount           NUMBER (3);
     vSuspectMed          VARCHAR2 (1);
     --vPrimaryFlag     VARCHAR2(1);
cursor c1 is
     select count(*) as vSusCount
     from ae_suspect_drugs aed

     and aed.case_id = ivCase_ID
     --group by ivcase_id;
BEGIN
open c1;
fetch c1 into vSusCount;
close c1;
IF vSusCount < 1 /*AND vPrimaryFlag IS NULL*/ THEN
     ovErrorText := 'Suspect Drug Count is less than 1' || 'SusCount: ' || vSusCount;
     ELSIF vSusCount = 1 /*AND vPrimaryFlag IS NULL*/ THEN
     ovErrorText := 'Suspect Drug count is equal to 1' || 'SusCount: ' || vSusCount;
     ELSIF vSusCount > 1 /*AND vPrimaryFlag IS NULL*/ THEN
     ovErrorText := 'Suspect Drug count is greater than 1 ' || 'SusCount: ' || vSusCount;
     ELSE
     ovErrorText := 'All criteria met';
END IF;
END COUNT_SUSPECT_MED;It seems like it would be more convenient to have a FUNCTION, rather than a PROCEDURE; that way you could call the function directly in a SQL statement (e.g., in the WHERE clause of a query or DML statement) as well as in PL/SQL.
The procedure you posted seems to be quite a bit differetn from the problem you asked eariler.
Here's one way you might write a fucntion for the earlier problem:CREATE OR REPLACE FUNCTION count_allergy_med
( ivPatient_ID IN VARCHAR2
RETURN VARCHAR2
IS
return_str VARCHAR2 (50);          -- To be returned
BEGIN
SELECT CASE
     WHEN COUNT (drug_role) > 1
          AND COUNT (primary_flag) = 1
          THEN 'SUCCESS'
          ELSE 'FAIL'
     END
INTO return_str
FROM ae_all_drugs     aed
,      ae_patient           ap
WHERE drug_role          = 'Allergy'
AND     aed.patient_id      = ap.patient_id
AND     ap.patient_id     = ivPatient_ID;
RETURN return_str;
END count_allergy_med;
Notice that there are no columns in the result set, nor variables in the function, that correspond to vAllergyCount or pf.
The function above returns 1 of 2 possible values. You couold just as well write a function that had 4 possible outcomes, or 4 basic results, each containing a variable number, such asSuspect Drug Count is less than 1. SusCount: 0
I'm not sure why you would want such as result, since 0 is the only possible count that is less than 1, but it's easy enough to produce results like that if you really want them.
Once again, if you'd like help, post a clear example of what you want. Include CREATE TABLE and INSERT statements for some sample data. Post some code where you might use the function that you're thinking of. Give a couple of different arguments for that functuion, and the results you would want for each argument given the same sample data.

Thank you sir, it really helped me to solve my problem, now it looks like this and working fine, i hope now there is no logical error in my code, please suggest.
i am really surprised by such a rapid response, i hope i will learn soon from GURUZz

Please help with multiple insert query into nested table!!!!

I am having a problem with inserting multiple references to objects into a nested table using the following query:
INSERT INTO TABLE(SELECT Taken_by FROM courses WHERE course_number= 001)
(SELECT REF(p) FROM persons p
WHERE p.enroled_in = 'Computing for Business'
The database says that p.enroled_in is an invalid identifier. I know why this is. This is because the field enroled_in is part of a subtype of person called student_type and the query above is not accounting for this properly. I would like to know the correct syntax to use so I can insert into the nested table wherever a student is enroled into the 'computing for business' course. My full schema is below:
CREATE TYPE person_type;
CREATE TYPE student_type;
CREATE TYPE staff_type;
CREATE TYPE course_type;
CREATE TYPE module_type;
CREATE TYPE address_type AS OBJECT
Street VARCHAR2 (30),
Town VARCHAR2 (30),
County VARCHAR2 (30),
Postcode VARCHAR2 (9)
CREATE TYPE person_type AS OBJECT
Name VARCHAR2 (50),
Address address_type,
DOB DATE
) NOT FINAL;
CREATE TYPE staff_type UNDER person_type
Staff_number NUMBER (2,0)
) FINAL;
CREATE TYPE student_type UNDER person_type (
Student_number NUMBER (2,0),
Enroled_in VARCHAR2(50),
MEMBER FUNCTION getAge RETURN NUMBER
)NOT FINAL;
CREATE OR REPLACE TYPE BODY student_type AS
MEMBER FUNCTION getAge RETURN NUMBER AS
BEGIN
RETURN Trunc(Months_Between(Sysdate, DOB)/12);
END getAge;
END;
CREATE TYPE module_type AS OBJECT
Module_number VARCHAR2(6),
Module_name VARCHAR2(50),
Credit NUMBER(2,0),
Taught_in VARCHAR2(50)
CREATE TYPE students_tab AS TABLE OF REF person_type;
CREATE TYPE modules_tab AS TABLE OF REF module_type;
CREATE TYPE course_type AS OBJECT
Course_number NUMBER (2,0),
Course_name VARCHAR2(50),
Dept_name VARCHAR2(50),
Taken_by Students_tab,
Contains Modules_tab
CREATE TABLE modules OF module_type(
constraint pk_modules primary key (Module_number)
CREATE TABLE courses OF course_type(
constraint pk_courses primary key (Course_number)
NESTED TABLE Taken_by STORE AS students_nt,
NESTED TABLE Contains STORE AS modules_nt;

By the way I am using oracle 9i and trying to insert into the nested table data from a subtype (i.e student is a subtype of person)

Multiple Rows Query

Hi
Table A have 2 Columns Col1, Col2.
I want to select all distinct values of Col1 that have 2 corresponding value ‘X’ and ‘Y’ in Col2
create table TabA
Col1 varchar(10),
col2 char(1)
insert into TabA values ('tem1','X');
insert into TabA values ('tem1','Y');
insert into TabA values ('tem1','Z');
insert into TabA values ('tem2','X');
insert into TabA values ('tem2','Y');
insert into TabA values ('tem2','Z');
insert into TabA values ('tem3','X');
insert into TabA values ('tem3','Z');
insert into TabA values ('tem4','Y');
insert into TabA values ('tem4','Z');
insert into TabA values ('tem5','X');I need a query that only return tem1 & tem2 as they have both X, Y in col2.
Wishes

Check this.
select distinct col1 from (
select A.*, count(case when Col2 in ('X','Y') then 1
end) over ( partition by col1) cnt
from TabA A)
Where cnt = 2
Regards
RKWill not work for all cases:
SQL> select * from taba;
COL1       C
tem1       X
tem1       X
SQL> select distinct col1 from (
2 select A.*, count(case when Col2 in ('X','Y') then 1 end) over ( partition by col1) cnt
3 from TabA A)
4 Where cnt = 2
5 /
COL1
tem1

Can I retrieve data from a multiple select query?

I recently have been able to consolidate many queries into one large one, or into large compound queries. I found an instance where I am using a select query in a for loop that may execute up to 400 times. I tried building a huge compound query, and using DB Tools Execute Query vi, followed by the DB Tools Fetch Recordset Data vi. The query executes at the database without an error, but the Fetch Recordset Data vi only returns the first instance. Is there a way to retrieve all the data without having to send up to 400 separate select queries?

Sorry I didn't replt earlier, I was on vacation. The query I am using is to check serial numbers, and determine if they are all valid. The programs purpose is to define a serial number to a pre-existing part number. Our company makes inclinometers and accelerometers, and this entire series of LabVIEW programs is designed to automate the calibration and testing of these units. The part number definitions can contain 3 or 4 hundred parameters, so the database itself consistes of 44 tables with potentially several hundred columns per table. It is designed to not only provide definitions to every part number, but also to store all potential raw unit data to be calculated and formed into a report at any time. The logistics of getting that much data in and out of the database have forced me to do things more effeciently. The actual query in question is to take each serial number either manually entered, or automatically picked, and see if they already exist with the part number they are being defined as. If there are any duplicates, then the program will alert the operator that serial numbers x, y, and z for instance have already been asigned as the part number in question. Currently I run a simple query once for each serial number. This works, but there may be 200 serial numbers assigned. Also the serial numbers can contain upper or lower case letters. By making all the serial number letters into capitals, then into lower case, it could mean up to 400 individual queries going out over the LAN. This is a bandwidth hog, and time consuming. I started experimenting with compound queries. The actual query used is below.
SELECT SERIALNO FROM "maintable" WHERE PARTNO = '475196-001' AND SERIALNO = '3000005';SELECT SERIALNO FROM "maintable" WHERE PARTNO = '475196-001' AND SERIALNO = '3000006';SELECT SERIALNO FROM "maintable" WHERE PARTNO = '475196-001' AND SERIALNO = '3000007';SELECT SERIALNO FROM "maintable" WHERE PARTNO = '475196-001' AND SERIALNO = '3000008';SELECT SERIALNO FROM "maintable" WHERE PARTNO = '475196-001' AND SERIALNO = '3000009'
When I execute this query, SQL Server 2000 has no problem with it, but the DB Tools Fetch Recordset Data vi only returns the first match. I think my answer may lie with OR statements. Rather than sending what amounts to potentially dozens of individual queries, I should be able to chain them into one query with a lot of OR statements. As long as the OR statement is not an exclusive OR statement, I think it should work. I haven't tried it yet, and it may take some time to get the syntax right. The query is built in a for loop with the number of iterations equal to the number of serial numbers being defined. Once I get this working I will alter it to include both upper and lower case letters that can be included in the query. Any suggestiona of how the query should be structured would be most helpful, or another way to achieve what I am trying to accomplish.
