How to count number of rows in table

can I get number of row in table except Count(*) in pl/sql
is there any other way

how to count number of rows in table
count(*) will be the fastest way. It is only slow if the table has a vast number of rows, in which case why do you need to know the tables has 73552436467721 rows and not 73552436467737 rows. It doesn't seem to be much use. Either that or you are counting them a lot, which again seems rather pointless.

Count number of rows in table

Hi!
1. How can you through ABAP and select statements count the number of rows in one table?
2. I want to read all rows from one table to an internal table. Can this be done dynamically or do I first have to count the number of rows in the table and then declare an internal table with the number of rows counted.
regards
Baran

HI,
No you don't have to count number of rows first, Internal table size will increase dynamically. you have to declare this with initial size like this.
data: itab type standard table of bkpf initial size 0.
SELECT * FROM bkpf into table itab.
All values from bkpf will be inserted into table internal table itab.

How to count number of ones in table

Hello,
i created one table 16x32 each cell is updating 1 byte of data,how to count number of one in all cell,and is it right way to calculate check sum??
thank you

The simplest way is to call GetTableCellRangeValues with VAL_ENTIRE_TABLE as the range, next summing array elements.
But I don't understand your comment on checksum, so this may not be the more correct method for your actual needs: can you explain what do you mean?

How to add the Row count(number of rows in table) in the table header?

Hi,
I'm having a table. This table is viewed when i click on a search button.
On the table header it should dynamically display the number of rows in the table, i.e., the row count.
How to do this? could any one explain me with the detailed procedure to achieve this.
Thanks & Regards,
Suresh

If you want to show a localized text in the table header, you should use the Message Pool to create a (parameterized) message "tableHeaderText" like "There are table entries".
Next, create a context attribute "tableHeaderText" of type "string" and bind the "text" property of the table header Caption UI element to this attribute.
Whenever the table data has changed (e.g. at the end of the supply function for the table's data source node), update the header text:
int numRows = wdContext.node<TableDataSourceNode>().size();
String text = wdComponentAPI.getTextAccessor().getText
IMessage<ComponentName>.TABLE_HEADER_TEXT,
new Object[] { String.valueOf(numRows) }
wdContext.currentContextElement().setTableHeaderText(text);
Maybe you want to provide a separate message for the case that there are no entries.
Alternatively, you can make the attribute calculated and return the header text in the attribute getter.

Hi,
Initialise one variable TOT_ROWS to 0.
Then in the for loop
tot_rows := tot_rows + +1 ;
so after for loop the value in the tot_rows will be the total records..
If u want it to get this value in the calling procedure of this , just declare tot_rows parameter as out parameter.
For sum of a column:
Initialise a variable sum_col to 0.
In the for loop
sum_col := sum_col+I_info.column_name
aprameter if u wish return this value as out..
I think this wil give u the o/p..
cheers,

Is it possible to show the count of number or rows in table on the Home page Tab button.

Is it possible to show the count of number or rows in table on the Home page Tab button.
On home page there is a Tab called Count and I want to show the count on the right corner of this tab button.
Please help

Create an application item. APP_HOME_COUNT.
Create an application process:
make the application process type "on new instance" if you only want this to run once
make it "on load before header" if you want to have the value set every page load
application process source:
select count(*) into APP_HOME_COUNT from <your table>
modify the tab name to reference the app item, maybe something like "Count(&APP_HOME_COUNT.)"
result should look like this "Count(5)"
Good Luck,

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

Actually i have a db table having 2 columns(columnA,time).db table has 70lac rows.I have to retireve all those values which are present min. 2 times in the interval of 10 minutes for a particular value of columnA. eg. columnA,time values are

Is it related to data Mining? i have 3 crore rows in database table.I have to search such type of many patterns in my application.I have spent hours looking for tutorials on Google. However I cannot seem to find anything that holds the hand? try to be more clear, i'm in lack of ideas in this problem, even it sounds like a classic. Can oracle java data mining solve the problem?

first of all thanks for reply, i will take care of your suggestion.
Number of rows in table : More than 3*10pow7(30 Milion rows)(But it can be more than 120 milion)
Actually i have to display all those rows which setisfy following criteria:( Specific value of column A should appear min 2 times in the interval of 10 minutes.)
for eg.
eg 1. {b,June-01-2011 10:14:12},{b,June-01-2011 10:15:12},{b,June-01-2011 10:17:12}{This set is appearing 3 times in the any interval of 10 minutes.}
EG2 {a,June-01-2011 10:13:12} is present only one time,so i dont want this rows in output.
EG# {e,June-01-2011 10:26:12},{e,June-01-2011 11:38:12} is present 2 times in db,but not in the interval of 10 minutes,so i dont want this rows as output.(t1=10:26:12,t2=11:38:12 difference is more than 10 minutes.)
In my eg. i specified only 2 columns but in actual scenario there will be 8-10 columns in table.This is only one pattern which i specified,but there are many more pattern which i have to search in db.As specified above in eg. was only one pattern,After fulfiling this pattern It has to pass many other pattern.and i want result should be retrieved very fast.
Please dont go into answer of above eg.Actually i want, what should be approach of such type of problems?
Is this problem related to oracle data mining and how?
Can data mining algorthms(Minimum Description Length ,Naive Bayes,Apriori,Decision Tree,Non-Negative Matrix Factorization ,Support Vector Machine...etc..) solve my problem?
Different-2 type of queries will be fired against this table?
if i am still not clear then let me know.
