Select query based on userinput

Hi Folks...
I posted this in another forum, but no reply,so I am posting it here too. I am trying to make a select query based on a user input. Earlier I was having probelms making a select query and printing out the result in the stack trace,with the advice given, I managed to solve that. I am now modifying that code to make a query based on user input, however it's not working, following is the code:
String userId = request.getRemoteUser(); String sql = "SELECT hoursused FROM sysuser WHERE iduser = ?"; try { Connection connection = dataSource.getConnection(); PreparedStatement preparedStatement = connection.prepareStatement(sql); preparedStatement.setString(1, userId); ResultSet srs = preparedStatement.executeQuery(sql); while(srs.next()) { String hoursused = srs.getString("hoursused"); System.out.println("The hours used are " + hoursused); } } catch (SQLException e) { e.printStackTrace(); } }
stack trace seems to suggest I may have a probelm with this statement:
"SELECT hoursused FROM sysuser WHERE iduser = ?";
I am not sure how to rectify this, I hope someone can advise, thanks.

Hi jschell..
Thanks for responding, I appreciate it. The problem has been solved. No 'sysuser' is not a reserved word in Mysql. Based on the advice given in another forum and also from this site, I managed to solve the problem. I only made one change. This:
ResultSet srs = preparedStatement.executeQuery(sql); was changed to this:
ResultSet srs = preparedStatement.executeQuery(); Thanks.

SELECT QUERY BASED ON SECONDARY INDEX

Hi all,
CAN ANYONE TELL ME HOW TO WRITE SELECT QUERY BASED ON SECONDARY INDEX.
IN WHAT WAY DOES IT IMPROVE PERFORMANCE.
i KNOW WHEN CREATING SECONDARY INDEX I NEED TO GIVE AN INDEX NO -iT SHOULD BE ANY NUMBER RIGHT?
I HAVE TO LIST ALL PRIMARY KEYS FIRST AND THEN THE FIELD FOR WHICH I AM CREATING SECONDARY INDEX RIGHT?
LETS SAY I HAVE 2 PRIMARY KEYS AND I WANT TO CREATE SEONDARY INDEX FOR 2 FIELDS THEN
I NEED TO CREATE A SEPERTE SECONDARY INDEX FOR EACH ONE OF THOSE FIELDS OR ONE SHOULD BE ENOUGH
pLS LET ME KNOW IF IAM WRONG

HI,
If you cannot use the primary index to determine the result set because, for example, none of the primary index fields occur in the WHERE or HAVINGclauses, the system searches through the entire table (full table scan). For this case, you can create secondary indexes, which can restrict the number of table entries searched to form the result set.
You create secondary indexes using the ABAP Dictionary. There you can create its columns and define it as UNIQUE. However, you should not create secondary indexes to cover all possible combinations of fields.
Only create one if you select data by fields that are not contained in another index, and the performance is very poor. Furthermore, you should only create secondary indexes for database tables from which you mainly read, since indexes have to be updated each time the database table is changed. As a rule, secondary indexes should not contain more than four fields, and you should not have more than five indexes for a single database table.
What to Keep in Mind for Secondary Indexes:

Select Query Based on date condition

Hi ,
Is it Possible.
i want to run select query based on date condition.
Eg...
if the date between 01-jan-01 and 01-jan-05 then
select * from table1;
if the date between 02-jan-05 and 01-jan-08 then
select * from table2;
Becaz i have data in 2 diffrent tables , based on the date condition i wnt to run the select statement to diffrent tables.
i dont want plsql here Just SQL needed.
thanks,

Helo Kanish,
this is not the one i was asking..
wht i mean was .
i use bind variable to get date while running the select statement , once i get the date then i want to choose any one of the table to run select query.
EG..
select col1,col2 from table1 where date between only if 01-jan-01 and 01-jan-05;
select col1,col2 from table2 where date between only if 02-jan-05 and 01-jan-08;
Run any one of the two . not all
thanks,

Select query based LOV for tabular form attributes

Hi HTMLDB Team,
Congrats u all for the new release of HTMLDB in htmldb.oracle.com.
I badly need a solution of the below problem.
Say , i have table called user_col_comments now i want to display the table_name ,column_name and comments in a tabular form.I displayed only one row for the tabular form.Now i create a select query based LOV for attribute table_name where i got all table_name in drop down list.
Point is that after selecting any data from drop down table list i want to get the corresponding fields to be populated in column_name attributes.How can i wrote the select query based LOV for the attibute column_name.
I wrote it as 'select column_name d,column_name r from user_col_comments where table_name=:TABLE_NAME Its not working?
Similarly i want same thing to display for comments after matching both table_name and column_name.
Any solution to get rid of those problem will be highly appreciable...
If u need my htmldb.oracle.com userid and password to solve the problem i will sure let u email it.
Cheers,
Eman

U are welcome to give me proper solution.....
Thanks for the reply ....atleast one can pay hid to me.....

Select query based on joining of tables from different database is taking too long

Hi Team,
Select query on table with millions of records is taking very long time. It took 50mins, the below query is joining on multiple table from two databases DB1.dbo.Table1 contains 100 million records and also Table3 and Table4 (of different database) might
contain close to 1million records.
Select T1.*
From DB1.dbo.Table1 T1
Join DB1.dbo.Table2 T2 on RTRIM(T1.Col3) = RTRIM(T2.Col3)
Join Table4 CA on RTRIM(T1.Col1) + T2.Col2 = CA.Col1
Join Table3 U on CA.Col2 = U.Col2 AND RTRIM(T2.Col2) = U.Col3
Where U.Col4 NOT IN ('A1', 'A2', 'A3', 'A4', 'A5', 'A6','A7','A8','A9')
And (T1.flg IS NULL OR T1.flg = 'N')
And LTRIM(RTRIM(T2.Col2)) NOT IN ('B1','B2')
How can i improve the performance of this query. Actual thing is update the data in Db1.dbo.table1 based on the conditions but if the select is taking close to 1hr then update will take hours together. Indexes already implemented on all the tables.
Thanks,
Eshwar.

Thanks.
Join Table4 CA on RTRIM(T1.Col1) + T2.Col2 = CA.Col1
This join is not working with spaces if Rtrim is not used.

when qty 9 will out the rate are 6 qty rate 458.1 and other 3 out rate of 457.2 means total value of 9 out qty value is 4120.20 .
Now 35 qty is completed and after that rate will continue with 457.2 till 10 qty not completed.
I think you understand my detail if not please tell me .
thanks
i am waiting your reply.

As SomeoneElse mentioned, there is no row order in relational tables, so you can't tell which row is first and which is next unless ORDER BY is used. So I added column SEQ to your table:

Select query based on Simple Type field in JDT

Hello Experts,
We have a JDT table consisting of a field "CONSUMPTION_ID" which refers to a Simpletype.So at oracle level the datatype of the field shows as CLOB instead of String. I am unable to use this simple type field in the WHERE clause in my bean .
Following are the queries i have tried and the errors i have got executing them :
Query1 - SELECT * FROM TEST_TABLE WHERE CONSUMPTION_ID <> 'RT'
Error - com.sap.sql.log.OpenSQLException: The SQL statement "SELECT * FROM "TEST_TABLE " WHERE "REF_MAT_DOC_NO" = ? AND "REF_MAT_DOC_YEAR" = ? AND "CONSUMPTION_ID" <> 'RT'" contains the semantics error[s]: - 1:84 - type check error: the expression >>"CONSUMPTION_ID"<< (CLOB) is not comparable and must not be used with "<>"
- 1:84 - type check error: the left hand side >>"CONSUMPTION_ID"<< (CLOB) and the right hand side >>'RT'<< (CHAR) of a comparison operator are not comparable

Problem in select query

Hi Friends
I am using a table a981 and fetching data in internal table but the table has a fieil Country whose technical name is ALAND in dev and LAND1 in production.Now i cannot use LAND1 as it wont let me to activate the report and if i use ALAND i cannot move the request to production as it fails. So how can i achive dynamic table field in the select query based on server.My query is-
select kschl
 wkreg
 matnr
 knumh
 from a981 into corresponding fields of table it_a981
 for all entries in it_marc where matnr = it_marc-matnr
 and kschl in ('MWST','ZSER')
 and aland = 'IN'
 and datab le sy-datum
 and datbi ge sy-datum.
I need to make aland dynamic.Pls suggest

If you insist on having a workaround, you could always create dynamic WHERE conditions.
DATA: cond TYPE string.
IF sy-sysid EQ <your dev sysid>.
 cond = 'matnr = it_marc-matnr
 and kschl in (''MWST'',''ZSER'')
 and datab le sy-datum
 and datbi ge sy-datum'
 and land1 = ''IN''.
ELSE.
 cond = 'matnr = it_marc-matnr
 and kschl in (''MWST'',''ZSER'')
 and datab le sy-datum
 and datbi ge sy-datum'
 and aland = ''IN''.
ENDIF.
select kschl
 wkreg
 matnr
 knumh
 from a981 into corresponding fields of table it_a981
 for all entries in it_marc where (cond).

How to write XSJS Select Query with input parameters

Hello Experts,
I am creating a xsjs file and in that file I am trying to write a Select Query based on a Calculation View
I have tried it the following way:
var query = 'SELECT TOP 100 \"Name\", \"Address\", \"City\", \"Country\" FROM \"_SYS_BIC\".\"Test.HL/AddressView\"'
+ 'WITH PARAMETERS(\'PLACEHOLDER\' = (\'$$P_Name$$\', \' Akhil \'),'
+ '\'PLACEHOLDER\' = (\'$$P_City$$\', \' Lucknow \'))';
But it gives me the "Mixed spaces and tabs error".
How should I write XSJS Select Query with input parameters?
Regards,
Rohit

>But it gives me the "Mixed spaces and tabs error".
Mixed spaces and tabs has nothing to do with the syntax of the statement. You used both spaces and the tab in the content - which JSLint doesn't like. Remove the beginning spaces of each line and use only one or the other.
The actual syntax of your statement doesn't look right. The problem is that you are escaping the \ when you don't need to if you are using ' instead of " for your string. You escape with \" in the first line but then escape with \' in the 2nd and 3rd line. That is going to cause serious parsing problems with the command.

Passing parameters to select query in DB link from invoke...

I am having a DB partner link which executes the select query based on user specified parameter.
Now i have created an invoke activity and specified input[this needs to be passed to query] and output parameters[this is query result]. This invoke activity calls DB partner link in which one parameter has been created to be used in select query. So my doubt is , will DB partner link take up the input parameter of invoke activity automatically or do we need to specify any mapping for this?

When you create a db partnerlink the parameter you create for your select is the input and when you create the input variable in the invoke for this partnerlink it is created with the right type for the parameter.
Create an Assign before your invoke and assign a value to the input variable you created in the invoke. That value will be passed and used as the parameter in the select.

How can i update rows in a table based on a match from a select query fron two other tables with a update using sqlplus ?
Thanks Glenn
table1
attribute1 varchar2 (10)
attribute2 varchar2 (10)
processed varchar2 (10)
table2
attribute1 varchar2 (10)
table3
attribute2 varchar2 (10)
An example:
set table1.processed = "Y"
where (table1.attribute1 = table2.attribute1)
and (table1.attribute2 = table3.attribute2)

Hi,

Hi, Frank
taking nulls into account, what if some attributes are null ;) then the query should look like
NOT TESTED !
update table1 t1
set processed = 'Y'
where exists(select null
from table2
where lnnvl(attribute1 != t1.attribute1)
and exists(select null
from table3
where lnnvl(attribute2 != t1.attribute2)
and processed != 'Y'Regards
EtbinYes, you could do that. OP specifically requested something else:
wgdoig wrote:
set table1.processed = "Y"
where (table1.attribute1 = table2.attribute1)
and (table1.attribute2 = table3.attribute2)This WHERE clause won't be TRUE if any of the 4 attribute columns are NULL. It's debatable about what should be done when those columns are NULL.
But there is no argument about what needs to be done when processed is NULL.
OP didn't specifically say that the UPDATEshould or shouldn't be done on rows where processed was already 'Y'. You (quite rightly) introduced a condition that would prevent redo from being generated and triggers from firing unnecessarily; I'm just saying that we have to be careful that the same condition doesn't keep the row from being UPDATEd when it is necessary.

Problem writing a sql query for a select list based on a static LOV

Hi,
I have the following table...
VALIDATIONS
ID          Number     (PK)
APP_ID          Number
REQUESTED     Date
APPROVED     Date
VALID_TIL     Date
DEPT_ID          Number     (FK)
I have a search form with the following field item variables...
P11_DEPT_ID (select list based on dynamic LOV from depts table)
P11_VALID (select list based on static Yes/No LOV)
A report on the columns of the Validations table is shown based on the values in the search form. So far, my sql query for the report is...
SELECT v.APP_ID,
v.REQUESTED,
v.APPROVED,
v.VALID_TIL,
d.DEPT
FROM DEPTS d, VALIDATIONS v
WHERE d.DEPT_ID = v.DEPT_ID(+)
AND (d.DEPT_ID = :P11_DEPT_ID OR :P11_DEPT_ID = -1)
This query works so far. My problem is that I don't know how to do a search based on the P11_VALID item - if 'yes' is selected, then the VALID_TIL date is still valid. If 'no' is selected then the VALID_TIL date has passed.
Can anyone help me to extend my query to include this situation?
Thanks.

Hello !
Let's have a look at my example:create table test
id        number
,valid_til date
insert into test values( 1, sysdate-3 );
insert into test values( 2, sysdate-2 );
insert into test values( 3, sysdate-1 );
insert into test values( 4, sysdate );
insert into test values( 5, sysdate+1 );
insert into test values( 6, sysdate+2 );
commit;
select * from test;
def til=yes
select *
from test
where decode(sign(trunc(valid_til)-trunc(sysdate)),1,1,0,1,-1)
       =decode('&til','yes',1,-1);
def til=no
select *
from test
where decode(sign(trunc(valid_til)-trunc(sysdate)),1,1,0,1,-1)
       =decode('&til','yes',1,-1);
drop table test; It's working fine, I've tested it.
The above changes to my first idea I did because of time portion of the DATE datatype in Oracle and therefore the wrong result for today.
For understandings:
1.) TRUNC removes the time part of DATE
2.) The difference of to date-values is the number of days between.
3.) SIGN is the mathematical function and gives -1,0 or +1 according to an negative, zero or positiv argument.
4.) DECODE is like an IF.
Inspect your LOV for the returning values. According to my example they shoul be 'yes' and 'no'. If your values are different, you may have to modify the DECODE.
Good luck,

Select List (query based LOV) in a wizard created report form

I have created an updatable report form with 3 columns:
app_id
user_id
group_id
Each app_id has multiple group_id's associated with it, and I want to show the group_id field as a Select List (query based LOV) that contains the groups associated with the app_id.
My query for the select list needs to be similar to the following:
SELECT DISPLAY_NAME, GROUP_ID
FROM APPLICATION_GROUPS
WHERE APP_ID = ?????
ORDER BY 1
The problem is, I don't know how to reference the app_id from the main report to replace the ?????.
In other words, if my report returns 2 rows of data like this:
app_id----------user_id----------group_id
1-----------------24------------------3
2-----------------24------------------15
Then how do I get the group_id column to be a select list of possible groups for each application? If app_id 1 has 3 groups associated with it, 3, 4, & 5 and app_id 2 has 2 groups associated with it, 15 & 16, then those each of the select lists should be based on the app_id.
Hopefully I explained this clearly.
Thanks,
Kris

Leo,
Thanks for the response, but I don't think you quite understand my problem. If I go to the Column Attributes screen for the group_id field, I have the "Display As" drop down set to "Select List (query based LOV)", not "Select List (named LOV)". This requires that the sql query be written in the "List of values definition" text area below. Within that text area I have the following query:
SELECT DISPLAY_NAME, GROUP_ID
FROM APPLICATION_GROUPS
WHERE APP_ID = ?????
ORDER BY 1
The APP_ID that I need to reference is for the current row of data that is being processed. Therefore, I can't use a :PNNN_APP_ID variable, because that field does not exist on the page.
Hopefully this explains it a little better.
Thanks,
Kris
