Table num_rows have no info

I tried to get a row count for all the tables in the db using this statement:
Select table_name, num_rows from user_tables
However, the num_rows returned nothing (blank for all the tables) when surely there are data present in most of the tables.
Please help.
Thanks!

I would rather use dbms_stats and issue gather auto on the table.
Also, I would run the dbms_stats gather statistics when there is less or no activity on the table.

Shadow tables that have been created via the new partitioning schema

Hi,
     Complete Partitioning :
                In a complete partitioning, the fact table of the infocube are fully converted using shadow
tables that have been created via the new partitioning schema.
               in the above Explanation what is the meaning of shadow tables which perform the
               partitioning of an info cube.

Hi
Shadow tables have the namespace /BIC/4F<Name of InfoCube> or /BIC/4E<Name of InfoCube>.
Complete Partitioning
Complete Partitioning fully converts the fact tables of the InfoCube. The system creates shadow tables with the new partitioning schema and copies all of the data from the original tables into the shadow tables. As soon as the data is copied, the system creates indexes and the original table replaces the shadow table. After the system has successfully completed the partitioning request, both fact tables exist in the original state (shadow table), as well as in the modified state with the new partitioning schema (original table). You can manually delete the shadow tables after repartitioning has been successfully completed to free up the memory. Shadow tables have the namespace /BIC/4F<Name of InfoCube> or /BIC/4E<Name of InfoCube>.
You can only use complete repartitioning for InfoCubes. A heterogeneous state is possible. For example, it is possible to have a partitioned InfoCube with non partitioned aggregates. This does not have an adverse effect on functionality. You can automatically modify all of the active aggregates by reactivating them.
Hope it helps and clear

I do not have the "info button" as an option pages at I downloaded onto my iPad2. All I have is the paint brush, plus sign in the box, and a wrench.

I watched a video on youtube http://www.youtube.com/watch?v=F2hC089Iri0 and noticed that I do not have the info button, nor the insert button or full screen button which are also described in the "Getting Started" document in pages on my ipad. Is this something I need to worry about?
Also wondering if you can make pages document in landscape or is it only for portrait?

With the latest release of iOS and iWork apps for iOS, Apple has changed the Toolbar buttons:
What used to be the i - Info Button where object properties and text were changed is now the Brush icon (For styles, I guess) but has the same basic function as the i icon before - select an object or some text and tap the brush and you can change basic attributes.
What used to be the Media Insert icon (representation of an image) is now the "+" Button with the same functions as the previous icon - you can add shapes, tables, charts and media
The Tools Menu (wrench) is the same as before except in Keynote it now also has the Transitions and Builds access menu (double diamond icon) which used to reside on the toolbar and is now tucked under the Tools Menu
The View Full Screen (double arrow icon) has been removed and the document is now always in full view, sort-of.
Apple has yet to update their Getting Started Files for Pages, Keynote and Numbers to reflect these changes so it is understandably confusing to users.

I have garage band ver 10.0.2 and am trying to add effects to an audio track but i have no info button or track info under the track tab. How do i get these things to show up on my program?

I have garage band ver 10.0.2 and am trying to add effects to an audio track but i have no info button or track info under the track tab. How do i get these things to show up on my program?

In GarageBand 10.0.2 you can no longer add all kinds of effects freely; this GarageBand '11 feature has been discontinued. Pick one of the predefined patches that already has the effects you want.
However, you can add effects from the predefined audio units.
You'll see the predefined effects on the track, when you open the Smart Controls. To add audio units, click the button and enlarge the the smart controls pane by dragging the dividing line to the Track Area upwards.

Converted access app to apex when run get no data found; table does have da

COnverfted MS Access app to apex. WHen I run the appliation I get no data found.
However the table does have data. HOw do I see what is actually running?
The pre-converted form saids its based on a query. The form and the query shows up as valid. I then converted the form. When I run it I get no data found. If I take the query that the form is based on and run in sqlplus I get data.
Another confusing thing is when I look at the page for the converted form, there is nothing in the source area for the region where the converted query results should be.
Did the conversion not work? How can I tell what is the source? Where should the results from the query be located?

Its a standard SQL query:
SELECT xtbl_MSDS_to_CAS.msds_id,
xtbl_MSDS_to_CAS.cas,
xtbl_MSDS_to_CAS.alias,
xtbl_MSDS_to_CAS.amount,
xtbl_MSDS_to_CAS.veh_prod,
xtbl_MSDS_to_CAS.compliance
FROM xtbl_MSDS_to_CAS
The name of the above query lets say for example purposes is MYQUERY.
After looking at the page def I see that the way the conversion tool worked is that in the page definition it has this in the Processes Section:
After Header:
Fetch Row from MYQUERY.
Then it says automated Row fetch.
I compared this to another form that was converted thru the migration APex tool as well and on that form that does work I found that:
The query(form) was converted and placed in a region and the source has the query. THat is, it was not in the process section but in the region: source section.
So why does the conversion tool decide to convert one and populate as a region source and the other as a process in the page definition?
THis is all very confusing.
Hope you were able to follow me.

Can I create a view based on two tables that have the same column name?

I have two tables A and B. Each table has 50+ columns.
I want to create a view that includes all the columns in A and all the columns in B. I created a view with a select statement that says
Select A.*, B.*
From A, B
where A.id = B.id
It returns an error because in each table I have a column that keeps track if a record has been changed called Modified_By. That's where it chokes up on I figure. I would like to write the view without explicitly writing each column name from A and B as part of the select statement. The actual select statement works fine and only bombs when trying to turn the select statement into a view.

You will have to type the full column list at least once. You can save a few keystrokes (i.e. alias. on every column) by providing the column names to the CREATE part instead of in the SELECT part. Something like:
SQL> desc t
Name                                      Null?    Type
ID                                                 NUMBER
NAME                                               VARCHAR2(10)
SQL> desc t1
Name                                      Null?    Type
T_ID                                               NUMBER
LOC_ID                                             NUMBER
NAME                                               VARCHAR2(15)
SQL> CREATE VIEW t_v (id, t_name, t_id, loc_id, t1_name) AS
2 SELECT t.*, t1.*
3 FROM t, t1
4 WHERE t.id = t1.t_id;
View created.HTH

Limit on the number of partitions a table can have

Hi,
It's been quite some time I'm thinking of a simple and the best solution to a performance issue in my application. Benefiting out of partitioning the table seems a simplest approach; it involves very minimal changes to my application code and in addition, it keeps the overall application logic 100% intact. However, at times, the number of partitions required can grow to as large as 500 thousand. I know of another application implementing as many as 50 thousand partitions for one of its tables. I'm wondering if Oracle recommends or poses any limit to a number of partitions the table can have. How does that limit, if it exists, vary if each of my table partition holds only a small amount of data; say, not more than 2 thousand records each of 1 KB size. What are the important considerations that one needs to keep in mind while creating the huge number of partitions for a table?
Any inputs on this would be a great help.
Thanks,
Aniruddh
ps: Consider Oracle releases 10g onwards.

I doubt if you are using partitioning for the right causes. Please explain how is your data structured and why you need to create so many partitions..?
when creating partition, you need to consider..
a) why you need to partition?
b) how is your data structured
c) how your data is indexed.
d) What kind of queries would you firing on this table to get the data. Will they use the partition key ?
Thanks,
Rajesh.

JOIN 2 tables that have same column ?

I need to learn how to join two tables that both have the same column name:
tbl1 - idskey
tbl2 - idskey
the idskey column holds a id_number
When I do the JOIN I would like to make sure that only Distinct records are joined from both tables and that any duplicates are removed in the final join. So if:
Tbl1 has a idskey of: 12345
and
Tbl2 has a idskey of: 12345
In the final JOIN I want to remove one of those duplicates.
I actually need to join 3 tables that have the same linking column names for the join, but if I learn how to do this correctly on 2, that will be a start.
10g for db, thanks!

Hi,
SELECT DISTINCT and GROUP BY are the most common ways to get unique results from non-unique keys. Exactly how you use them depends on exactly what you want to do.
SELECT DISTINCT guarantees that no two rows in the result set, conisdering all columns, will be identical.
GROUP BY produces one row from a set of rows that have a common feature. The values on that row may be a composite of values from various rows in that set (e.g., an average).
Please post a small, specific example. For instance:
"I have two rows in tbl1 ...
and these fhtee rows in tbl2 ...
Notice how there is one row with idskey=12345 in tbl1 but two such rows in tbl2.
How can I get theses results ...
where only one row has idskey=12345?"

Ms sql - {"The referenced table must have a primary or candidate key. [ FK Name = ForeignKeyB_Details ]"}

I have a txt file which has all the sqltext in it separated by semi colon .Then I try to run a query one by one like this-
var conn = new SqlCeConnection(ConnectionString);
conn.Open();
var cmdArray = Regex.Split(sqlText, ";");
var cmd = new SqlCeCommand(null, conn);
foreach (var text in cmdArray)
cmd.CommandText = text;
if (!text.Equals(string.Empty))
cmd.ExecuteNonQuery();
else
break;
conn.Close();
I get the error {"The referenced table must have a primary or candidate key. [ FK Name = ForeignKeyB_Details ]"}
here is part of my txt file-
CREATE TABLE A
PrimaryId nvarchar(10) NOT NULL REFERENCES C(PrimaryId),

ALTER TABLE B ADD CONSTRAINT ForeignKeyB_Details FOREIGN KEY(UserId, UserFirstName, UserMiddleInitial, UserLastName, PhoneNbr, Extension, FaxNbr, Email) REFERENCES A(UserId, FirstName, MiddleInitial, LastName, PhoneNumber, PhoneExtension, FaxNumber, EmailAddress);

Hi,
Foreign key columns are frequently used in join criteria when the data from related tables is combined in queries by matching the column or columns in the FOREIGN KEY constraint of one table with the primary or unique key column or columns in the other table.
For more information about the foreign key constraint, please refer to this link:
http://msdn.microsoft.com/en-us/library/ms175464.aspx
