Getting # of rows returned in JDBC resultset
Hi,
Is there an easy call to get the number of rows in a resultset?
Right now I want to display en entire record if there's only one and display only a subset of record info if there's more than one.
I ended up doing the following:
while(rs.next()) {
i++);
then I call rs.beforeFirst(); to get back to the beginning of the result set and set my conditionals to operate on the "i" variable I created before.
There must be a rs.maxcount() or something to that effect isn't there? I'm using a JDBC2.0 type 4 postgreSQL driver. It supports Datasourcing, but not much else.

Hi,
You can do it in two ways,
1. As stated above, you can do it.
For more information,
http://java.sun.com/j2se/1.3/docs/api/java/sql/ResultSet.html
2.You can use a seperate prepared statement that returns nothing but a count of the rows that will be selected. i.e. select count(*) from Table,
Instead of * you can also use any column existing in Table.
Hope this helps.
Best Luck!

Number of rows returned by the resultset is wrong
Hi All,
I have pasted the code i used for JDBC. The problem is the number of rows returned by the resultset is 5 times that of the original data. Is something wrong with my code. Can anyone pls point out the mistake I have done if any.
public ArrayList dataBreakup(String team, int monthNo, int year) { String sqlDataBreakup = ""; Connection con1 = null; Statement stmt = null; ResultSet rs = null; ArrayList data = new ArrayList(); int noRows = 0; Calendar cal = Calendar.getInstance(); Calendar cal2 = new GregorianCalendar(cal.get(Calendar.YEAR), monthNo, 1); int days = cal2.getActualMaximum(cal2.DAY_OF_MONTH); String start_date = "01-Jan-" + year; String end_date = days + "-" + monthName[cal2.get(Calendar.MONTH)] + "-" + cal2.get(cal2.YEAR); System.out.println("START: " + start_date); System.out.println("END: " + end_date); databaseConnection dbObject = new databaseConnection(); try { con1 = dbObject.GetConnection(); stmt = con1.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE); sqlDataBreakup = "Select * from EXPENSE_STORE WHERE " + "team='" + team + "'AND category != 'Pending PO''s' AND ACCOUNTING_DATE " + "BETWEEN to_date('" + start_date + "') AND to_date('" + end_date + "')"; rs = stmt.executeQuery(sqlDataBreakup); ResultSetMetaData rsmd = rs.getMetaData(); int numColumns = rsmd.getColumnCount(); data.add(numColumns); for (int i = 1; i < numColumns + 1; i++) { data.add(rsmd.getColumnName(i)); } while (rs.next()) { noRows++; for (int i = 1; i < numColumns + 1; i++) { switch (rsmd.getColumnType(i)) { case java.sql.Types.NUMERIC: data.add(rs.getFloat(i)); break; case java.sql.Types.DATE: data.add(rs.getDate(i)); break; default: data.add(rs.getString(i)); break; } } } data.add(1, noRows); rs.close(); } catch (SQLException SQLe) { System.out.println("DumpData() : SQL Exception" + SQLe.getMessage()); SQLe.printStackTrace(); } catch (Exception e) { System.out.println("DumpData() : Other Exception"); e.printStackTrace(); } finally { dbObject.CloseConnection(con1); } return data; }
Thanks
Cheers N...Only thing i can say is
try the following
replace your function by this one and tell us the console output of the same
public ArrayList dataBreakup(String team, int monthNo, int year) {
String sqlDataBreakup = "";
Connection con = null;
ArrayList data = new ArrayList();
int noRows = 0;
Calendar cal = Calendar.getInstance();
Calendar cal2 = new GregorianCalendar(cal.get(Calendar.YEAR), monthNo, 1);
int days = cal2.getActualMaximum(cal2.DAY_OF_MONTH);
String start_date = "01-Jan-" + year;
String end_date = days + "-" + monthName[cal2.get(Calendar.MONTH)] + "-" + cal2.get(cal2.YEAR);
System.out.println("START: " + start_date);
System.out.println("END: " + end_date);
System.out.println("START: " + start_date);
System.out.println("END: " + end_date);
databaseConnection dbObject = new databaseConnection();
try {
con = dbObject.GetConnection();
sqlDataBreakup = "Select * from EXPENSE_STORE WHERE " +
"team = '"+team+"' AND category != 'Pending PO''s' AND ACCOUNTING_DATE " +
"BETWEEN to_date('"+start_date+"') AND to_date('"+end_date+"')";
System.out.println("-----------sql starts---------------");
System.out.println(sqlDataBreakup);
System.out.println("-----------sql ends---------------");
PreparedStatement pstmt = con.prepareStatement(sqlDataBreakup);
pstmt.setString(1, team);
pstmt.setString(2, start_date);
pstmt.setString(3, end_date);
ResultSet rs = pstmt.executeQuery();
ResultSetMetaData rsmd = rs.getMetaData();
int numColumns = rsmd.getColumnCount();
data.add(numColumns);
for (int i = 1; i < numColumns + 1; i++) {
data.add(rsmd.getColumnName(i));
while (rs.next()) {
noRows++;
for (int i = 1; i < numColumns + 1; i++) {
switch (rsmd.getColumnType(i)) {
case java.sql.Types.NUMERIC:
data.add(rs.getFloat(i));
break;
case java.sql.Types.DATE:
data.add(rs.getDate(i));
break;
default:
data.add(rs.getString(i));
break;
//data.add(1, noRows);
System.out.println("no of Rows : " +noRows );
} catch (SQLException SQLe) {
System.out.println("DumpData() : SQL Exception" + SQLe.getMessage());
SQLe.printStackTrace();
} catch (Exception e) {
System.out.println("DumpData() : Other Exception");
e.printStackTrace();
} finally {
dbObject.CloseConnection(con);
return data;
}and try running the sql printed on the screen in your db and then let us know the result.
in this code i have removed some of your code in order to simplify the problem. -
How to get # of rows in SQL Query ResultSet
I need to get the # of rows in a sql query resultset so I can create arrays of the size of the # or rows returned. This is how I do it so far. Is there a better way without running the query twice?
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(query);
while (rs.next())
i++;
aid = new int;
i=0;
rs = stmt.executeQuery(query);
while (rs.next())
aid[i] = rs.getInt(1);
Theres actually a few more arrays but for this I just used one to show what I was doing. Notice stmt.executeQuery needed to be called twice, once to get the count to set the size of the array and once to get the values.nope - there's no easy way.
the right thing to do is to iterate through the ResultSet, load its contents into a List of Objects or some other data structure, and close it out right away. You can get the count of rows while you do it. return the contents in the object or data structure for clients to use. you should never be passing a ResultSet around.
why do you need to know, anyway?

How to get the row Count of a ResultSet
How to get the row Count of a ResultSet
Hi
I'v tried rennie1's way ,but I only get zero,my code is:
rs.executeQuery("select count(*) from t_test");
if (rs.next()) int rowCount=rs.getInt(1);
I also tried barni's way ,but the method rs.last() and rs.beforeFirst() throw a same Exception
I tried another way,the code is:
while rs.next(){
// Do nothing ,just move the cursour to the last row
int rowCount=rs.getRow()
However,the rowCount still equal zero
Any help would be greatly apprecite!

How to get the row's size of ResultSet ?
i can't find a method to return the record number of a ResultSet.
how can i get it without using the next() method and select count(*) from sometableIf you use a scrollable ResultSet, you can do something like this:
int currRow = rset.getRow();
rset.last();
int numRows = rset.getRow();
if(currRow == 0)
rset.beforeFirst();
else
rset.absolute(currRow);

When I run my query (below) I only get 100 rows returned.
I am a little rusty with SQL so I think that I must be doing something simple wrong. Here is the query:
SELECT Tagname, Value, DateTime
FROM Insql.Runtime.dbo.AnalogHistory
WHERE "DateTime" > 'February 26 2014 10:30'
AND "DateTime" < 'February 26 2014 10:50'
AND Tagname = 'T0201001'
This is a wonderware plant historical database that collects analog data every 5 seconds.
No matter the time frame, 5 minutes or 5 hours I get back 100 rows of evenly time spaced data.
I went into the query options and edited them to no avail. I am sure that I could calculate how mainy rows I think that I should have and select that number but I assumed the given the date range it would figure that out by itself.I got the same result running:
SELECT Tagname, Value, [DateTime]
FROM Insql.Runtime.dbo.AnalogHistory
WHERE [DateTime] > 'February 26 2014 10:30'
AND [DateTime] < 'February 26 2014 12:50'
AND Tagname = 'T0201001'I am running my query from Microsoft SQL Server Management Studio 10.0.2531.0.I have been running this DB since 2000 (obviously in older versions of SQL).The DB was developed out of corporate and we just add tags through the WonderWare InSQL Historianwe can access the data through several trending applications. I was just teying to directly access the datato do some analsys with the raw data. I did check the Query options in Microsoft SQL Server Management Studioand it didn't appear to help. I was assuming that there was some default limitation but could not locate a setting anywhere. -

No rows returned in the BIS views
I am new to Discoverer. I had connected to Financials Intelligence responsibility using discoverer desktop. When I tried to create a workbook in General Ledger Business Area to display the GL accounts, I get no rows returned message. I get the same message for any kind of report I try to create not only in GL business area but also in any of the seeded business areas provided by the Oracle. I can query it in toad and see the data but it is not retrieved in discoverer. what could be the problem? is there any profile options to be setup for my username or am I missing something?
Any help is greatly appreciated
ThanksHere's the metalink note for those interested.
It's basically laying out all the steps to setup the info in Oracle Apps as alluded to by Simon and then perform a complete refresh of the BIS views in the database, bring in the new .eex file for changes, etc.

Oracle Applications 11.5.10.2
Oracle Applications Concurrent Manager SymptomsUnable to retrieve any data on standard General Ledger (GL) business areas and standard workbooks after migrating the EUL from Discoverer 4.1 to 10.1.2 and upgrading Oracle Applications to 11.5.10.2.
These same workbooks and business areas worked fine before the upgrade to Discoverer 10.1.2.
A custom business area and custom workbooks return data, but none of the standard pre-seeded "BIS" or "Financials Intelligence General Ledger (GL) business areas return data when testing in Discoverer Plus, Viewer or Desktop.
ChangesMigrated the Discoverer EUL and Oracle Application Server environment from Discoverer 4.1.48.08 to 10.1.2.48.18. CauseIncomplete setup of Oracle E-Business Suite and Discoverer environment for Business Intelligence (BIS) and/or Financials Intelligence, including missing profile options for Oracle Applications Administrator and custom Super User responsibility.
SolutionTo implement the solution, please execute the following steps:
1. Login to Oracle Applications Systems Administration function as SYSADMIN user and set the profile option as described below:
a. Profile > System
b. Check the 'Site', 'Responsibility' and 'Profiles with No Values' checkboxes
c. Enter "Applications Administration' in 'Responsibility' field
d. Enter FII: GL BIS Discoverer access (if it does not display the profile option, please try wildcard option "FII%GL%BIS%" )
e. Then in the next screen, select 'Yes' from LOV under 'Site' and 'Responsibility' column
f. Save the settings
g. Again repeat the same steps for custom responsibility "My_Company General Ledger Super User"
2. Complete/confirm the following steps from Note 313418.1, Section 6, Post Installation Tasks
a) Step 4. Regenerate your Business Views - done throughNote 313418.1, Section 6, Post Installation Tasks
a) Step 4. Regenerate your Business Views - done through Oracle Applications Concurrent Manager as SYSADMIN user with the "Business Views Setup" responsibility.
b) Recommend all steps under 4 and steps under 5
c) Step 8. Refresh the Discoverer 10.1.2 End User Layer - via SYSADMIN user/responsibility - as described in note
d) Step 9 -> Need to make sure Applications Administrator responsibility has all
security and access to the EUL and business areas. Be sure to grant to responsibility
rather than SYSADMIN user since the "Applications Administrator" responsibility is used to perform Discoverer Administration tasks.

How to run a select count(*) with multiple rows returned
Hi,
I have to run a select count(*) for different reports.
1) Select count(*) from table
where state = 'CA'
2) Select count(*) from table
where state = 'NY'
3) Select count(*) from table
where state = 'NV'
Instead of running this query again for 50 times, is there a way for me to just put it in one query and get multiple row returns? Thank you.Samantha wrote:

Getting the number of rows returned from ResultSet
Hi,
Does anyone know a method to get the number of rows returned with a query using the Resultset class?
Thanks.Hi 281080,
If your database and JDBC driver support it, in order to use the solution that da-alexj has suggested, you need to create a 'scrollable' "ResultSet" -- the javadoc for method "createStatement()" (in class "java.sql.Connection") has more details.
However, I have found with Oracle 8.1.7.4 database and Oracle (thin) JDBC driver, that part of their implementation of the "last()" method (in class "java.sql.ResultSet") is to actually iterate through the entire "ResultSet" in order to reach the last row. If your "ResultSet" is very large (I tested it with a 100,000 row "ResultSet"), this will take a long time.
Just wanted to make you aware of that.
Of-course, this may be irrelevant to you since I didn't see any mention in your post of what database and JDBC driver you are using.
Hope this has helped you, anyway.
Good Luck,
Avi. -
How to get number of rows return in SELECT query
i'm very new in java, i have a question:
- How to get number of rows return in SELECT query?
(i use SQL Server 2000 Driver for JDBC and everything are done, i only want to know problems above)
Thanks.make the result set scroll insensitve, do rs.last(), get the row num, and call rs.beforeFirst(), then you can process the result set like you currently do.
String sql = "select * from testing";
PreparedStatement ps =
con.prepareStatement(sql,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
ResultSet rs = ps.executeQuery();
rs.last();
System.out.println("Row count = " + rs.getRow());
rs.beforeFirst();~Tim

Can we proceed even if no ResultSet Returned In JDBC Sender Adapter ?
Hi friends ,
My scenario is JDBC to RFC . I am reading table using JDBC Sender Adapter and i am passing values to RFC .
If my select Query has not returned any row then it won't come to Pipeline right ?
What i want is
<b> If no rows returned then call one RFC to insert the remarks .
If rows found call another RFC to insert the values </b>
How can i handle the Situtation ?
Expecting your reply asap
Regards.,
V.RangarajanHi Rangarajan,
i answered your question and shown up a solution: If Connection Lost in JDBC or no resultset returned how to handle ?.
Double postings makes it difficult for all involved people to inform theirselfes about the point of discussion.
The polling sender adapter is doing nothing, if no rows selected. So how do want to send a message?
You have to use the JDBC receiver adapter, invoke the message by a job in ERP, for example with a self written RFC or a proxy. You can decide at ERP side, which function module it to be called. Of coz there are other possibilities, for example to put the logic into a business process, but you wont have success with the sender adapter.

How to get all rows that are returned in inner sub query of select statemen
If a sub query in select statement returns more than one row than how to get all those returned rows in the final
output of the query .It will be all right if all column's value repeat and that multiple output of inner query comes
in another column .
How to get that ?As Frank said, you likely want a join, and likely an outer join to replicate the select in the projection. Something like:
SELECT id,stat, section, USER_ID concerned_person
FROM table_all,
left join table2
on room_id = sectoion and
sur_role = 'r001'
WHERE section IN (SELECT code
FROM t_area
WHERE dept= 'p002')An alternative, depending on where and how you are using the statement would be something like:
SQL> WITH t AS (
2 select 1 id from dual union all
3 select 2 id from dual),
4 t1 as (
5 select 1 id, 'One' descr from dual union all
6 select 1, 'Un' from dual union all
7 select 1, 'Une' from dual)
8 SELECT t.id, CURSOR(SELECT t1.id, t1.descr from t1
9 WHERE t1.id = t.id)
10 FROM t;
ID CURSOR(SELECTT1.ID,T
1 CURSOR STATEMENT : 2
CURSOR STATEMENT : 2
ID DESCR
1 One
1 Un
1 Une
2 CURSOR STATEMENT : 2
CURSOR STATEMENT : 2
