What tool are you using to insert the data (application you are building or a management tool) it looks like a management tool so try:

INSERT INTO rentals VALUES (1, 7782, TO_DATE('02/02/2010 09:45:00'), 'PQ07JHG');

I do believe todate takes a string literal as the first parameter.

The software I'm using is Oracle SQL Developer.

I tried the above and got the error: "not a valid month".

I also tried this (the only different from the original post is that I put '' around them)

INSERT INTO rentals VALUES (1, 7782, to_date('02/02/2010 09:45:00', 'dd/mm/yyyy hh24:mm:ss'), 'PQ07JHG');

And with this effort, I got the error:

"format code appears twice"

MySQL tables crashed

Hi everyone,
I'm a software developer and just started my professional career life, question here i want to ask is ... that few days ago i was at client site to resolve some issue in application deployed by a company that uses MySQL for database, what i was found that there are four MySQL tables were crashed due to low harddisk space issue (I've searched on net that this is a usual problem with MySQL) that then i repaired by using myisamchk command. Error shown by MySQL when these were accessing is [table name] marked as crashed and should be repaired.

ok so this was the background scenario, now what i want to know/ask here is ... as described in above details that these 4 four tables were not accessible becuase they are crashed but I took a backup of this database and restore it to MySQL at another machine then i can access these table easily with no issue/error by MySQL, SO WHY THIS HAPPENS THAT AT ONE SIDE THESE ARE AS CRASHED AND ON ANOTHER THE BACKUP OF SAME DATABASE THAT WAS TAKEN WHEN THESE TABLES ARE CRASHED ARE THEN WORKING FINE.

I really will appreciate any kind of help on this topic Im just asking this for knowlegde and second thing is my boss also asked me the same question Poke tongue | ;-P

If I had to guess - because of low hard disk space.

By the way...really, really bad idea to let a database server run out of hard drive space. Doesn't matter what type of database either.

The message might be a bit misleading. Crashed does not mean your tables are goofed up, it only means that the database engine has set an internal flag on those tables that indicate that the tables can no longer take new rows because of lack of space.

Once you move your database to a new server, your database engine is smart enough to recalculate the new space and removes the flag.

Merget Replication Issue

Hi,
I am trying to make a merge replication between 2 remote machines: The remote server is running Windows 2008 Server with SQL database Server 2008 , the other local machine is running on a Windows7 and running also 2008 SQL Server.

I have configured my distribution database on the server and I have made a shared folder and gave it all the needed authority on the same Server as well.Then I have configured the Publisher on the same server along with the distribution and according to my reading that's the common used configuration.

Then I have configured my Subscriber on the local machine (Windows 7) with the same version of database.

However, once I start monitoring the replication from the subscriber I get this error "The schema script for tablename.csh could not be propagated to the subscriber". When I look into the publication side I see that there is an error about accessing the shared folder that I have created on the server, basically it cannot read it but I am sure that I have added all the needed authority for read/write to that folder, and I put this folder under the Administrators account and also I can see it under Computer management under the shared folder.

Sorry for my long question but I have worked hard on this and I would appreciate any help from the community.

Where did I go wrong with this? Is it the way I have shared this folder? Or the security agent.

I have followed the tutorial on this link http://www.sqlservercentral.com/stairway/72401/[^] which is really good but still I am getting the same error.

Your help is highly appreciated!!

Thank you!

Help with Calculations

I need your help . i have a spreadsheet In the Spread Sheet in the First line there is a field “Unit Type Total PQ”.

That field is calculated from =F2*D2 and the value of F2 = 0.05 and D2 = 12 so Excel reports that the Field “Unit Type Total PQ” results into 0.56.

If I take a CALCULATOR and multiply 0.05 * 12 I get 0.6

And if I go to SQL I get with this

SQL

SELECT  CONVERT(DECIMAL(10,2),0.05) * 12

I get 0.60

Why is Excell giving me Incorrect values or how can i fix my SQL

Hi Vuyiswa Maseko, Excel by default remove zero number from decimal value, if you want to display decimal value with 2 numbers with separator then right click on cell and Format Cells.. option then select Number category, there you can see option decimal places, where you can set 2 or another decimal places.

SQL queries for multiple columns depends on same column of another table

AhmedMasum19-Mar-12 8:21

See the following scenario:

Tables for the question:

SQL

Table : T1
c10  c12
---  ----
e1   A
e2   B
e3   C

Table: T2

c1  c2  c3  c4  c5   C6
--- -- --- ---  ---  ---
1   P  e1  e2   null  X
2   Q  e3  null null  Y
3   R  e2  e1   null  X
4   S  e3  e1   e2    Z


The c3, c4 and c5 columns of T2 table depends on c12 column of T1 table.

I want the following output:


c1  c2  c3  c4  c5
--- -- --- ---  ---
1   P   A   B   null
2   Q   C  null null
3   R   B   A   null
4   S   C   A   B

Can you help me to write an SQL to retrieve the above output from the table T1 and T2?

The SQL may be like:

SQL

Select c1, c2, t1.c12 as c3....... from t1, t2 where join condition

But I am not getting the actual sql in my mind.
So please help me regarding this.

I think it would be something like this:

SQL

SELECT c1, c2, tbl1.c12 AS c3, tbl2.c12 AS c4, tbl3.c12 AS c5
FROM 
     T2 LEFT OUTER JOIN 
     T1 AS tbl1 ON T2.c3 = tbl1.c10 LEFT OUTER JOIN
     T1 AS tbl2 ON T2.c4 = tbl2.c10 LEFT OUTER JOIN
     T1 AS tbl3 ON T2.c5 = tbl3.c10

from table2 t2
inner join table1 t1 on t1.c10  = t2.c3
left join table1 as t11 on t11.c10 = t2.c4
left join table1 as t111 on t111.c10 = t2.c5

Hi All,

I have two databases Example -A1 and A2, both are linked in SQL Server2008. I am pulling 3 tables information from A1 database and putting it into A2. But I am doing this manually by running the below queries

Example :
insert into TMP_ITEMS select * from A1..DEX.items

How to make this as a automatic process.

Thanks,

How about using a trigger on the insert. As each record is inserted into one database, a similar record can be inserted into the other. Smile | :)

What database system are you using? Oracle, MS SQL, Other?

I assume MS. It sounds like a permission problem. Might I suggest creating a SQL login with the desired permissions on all systems.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
