Sql query to add row id without loops

I am aware of the statement SELECT ROW_NUMBER() OVER (ORDER ...
But we need more functionality. Can we make the row_number to repeat counting from 1 after a specific field changes in value. I know how to achieve what I want using a cursor within a stored procedure. Is there a way we
achieve the same just using sql statements and without stored procedure/loop
For example, we have built the following resultset using an sql query and the result is already sorted by the first field, CompanyName:
CompanyName, department, ManagerName
A-company, Account, Steven
A-company, HR, Mark
A-company, IT, Susan
B-Company,IT,Ross
B-Company,Customer Service, Jack
C-Company,Finance, Matthew
C-Company,Finance, Helen
C-Company,Finance, Ron
I want to have a rew result with one additional column which is incremented automatically but the value must re-start from 1 once the Companyname changes.
1, A-company, Account, Steven
2, A-company, HR, Mark
3, A-company, IT, Susan
1, B-Company,IT,Ross
2, B-Company,Customer Service, Jack
1, C-Company,Finance, Matthew
2, C-Company,Finance, Helen
3, C-Company,Finance, Ron
Please enlighten me.

You have to program the numbering yourself. There is no built-in automatic numbering like identity or sequence but only OVER PARTITION BY.

[Excel] Running a SQL Query to delete rows

Hello Experts,
Background: I am attempting to use a dba of my companies time keeping system and implement it with Power BI tools. Given the file size restrictions within Power Bi itself I need to lower my file size by removing all time logs from
inactive employees.
I have a question regarding whether or not you can use a sql query to delete rows in excel. I have roughly 200,000+ rows in my excel spreadsheet. I am attempting to delete all rows where an employee equals inactive. I have attempted to
delete these rows by sorting them and doing a bulk delete and clear contents, but it seems to crash my excel every time. My thought process is that using a query that does a timed delete might put less of a burden on deleting the massive amount of data.
I would like to use this: DELETE * FROM [Table_(...)_Actual$] WHERE [Current] = "Inactive" (Will add more once I know it is possible to use sql queries in Excel.
Any information on whether or not this is possible would be appreciated.
Regards,

Running SQL Query in Excel is possible, however, the delete query is not supported in Excel.
You are more restricted in deleting Excel data than data from a relational data source. In a relational database, "row" has no meaning or existence apart from "record"; in an Excel worksheet, this is not true. You can delete values
in fields (cells). Please see:http://support.microsoft.com/kb/257819/en-us
One workaround : Use update query to set the rows as null, then use select query.
e.g.
SQL = "update [sheet2$A1:B5] set name=null,age=null where name='andy'"
cnn.Execute SQL
SQL = "select name,age from [sheet2$A1:B5] where name is not null"

Need help in SQL Query: Update a row in a table & insert the same row into another table

I want to update a row in a table say Table A and the updated row should be inserted into another table say Table B. I need to do it in a single SQL query and i don't want to do it in PL/SQL with triggers. And i tried with MERGE statement but its working with this scenario. (Note: I'm using Oracle Database 10g Enterprise Edition Release 10.2.0.1.0).
Thanks in Advance.

Using Sven's code as an example, you could save the updated row in a sql plus variable. (also untested):
SQL> var v_id number
update tableA
set colB='ABC'
where colC='XYZ'
returning id into :v_id;
insert into table A_History (ID, colA, colB, ColC)
select id, ColA, ColB, ColC
from tableA
where id = :v_id;

Sql query union double rows

Hi,
i have a problem with my sql query.
I need the difference from query 2 - query 1.
the red marked row should be ignored because its already in table 1.
Union compares all colums not just the first 3.
Here's a screen of the problem:
http://c60.img-up.net/?up=screenoracskt6.JPG
thx for all

Hi,
Welcome to the forum!
Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and the results you want from that data.
Explain how you get those results from that data.
Always say what version of oracle you're using.

Union compares all colums not just the first 3.That's right; UNION compare all the columns selected. If you're only interested in 3 of the columns, then only select those 3.
If you need to display more columns, but not where all 3 of them match, then the best way is probably an outer join; but there are lots of other ways, including NOT EXISTS, NOT IN, and MINUS (in a sub-query).

Displaying SQL Query results in rows instead of Columns

Hi,
I'm fairly new to Oracle so forgive me if this is a really stupid question.
I used Mysql for a while and if I wanted to display query results in rows instead of columns I could end the SQL command with '\G' instead of a semicolon.
This would give me output like...
Column_1: AAAA
Column_2: BBBB
Column_3: CCCC
Instead of the normal
Column_1 Column_2 Column_3
AAAAAA BBBBBBB CCCCCCC
Is there an equivalent in SQLPlus to the MySQL \G termination?
Thanks.
John

> so forgive me if this is a really stupid question.
It is certainly not a stupid question, but pivoting is a very frequently asked and answered question:

Why does Oracle SQL query returning a date field without the time component

Hi,
I'm a novice SQL user & hv just installed Oracle SQL developer (Version 3.0.04, Build MAIN-04.34).
I made the same SQL query using "Oracle SQL developer" & "TOAD for Oracle 9.0.1" but I got 2 different format on the same date field:
On TOAD, I get the date field extracted as *04/26/2011 23:12:58*
On Oracle, I get the date field extracted as *26/APR/11*
Why is the Oracle result in a different format & missing the time component?
Is there any option/preference that I need to set in Oracle SQL developer to get the full date/time format displayed?
I've tried to set my the date format to DD/MON/RR HH12:MI:SSXFF AM under the preference -> database NLS but I still get the same format!
Plse help!

SQL query returns few rows, but holds on with several Gbs of RAM memory used

If I perform the following query:
SELECT d.DocumentGUID, d.DocumentID
FROM ImportDataBase.dbo.Document d
LEFT OUTER JOIN ContentDataBase.dbo.Document d2 ON (d.DocumentGUID = d2.DocumentGUID)
WHERE ( d2.DocumentGUID IS NULL ) -- new document in the ImportDB
OR ( d2.DocumentGUID IS NOT NULL AND d.QueryContent <> d2.QueryContent ) -- modified document in the ImportDB
It returns around 1000 rows and takes about 3 minutes to complete
It also raises up the RAM memory used from 2GB to 9GBs.
This memory used will remain used untill I restart the server. I have no need to make use of that memory, I already copied the returned rows of that query into a note pad for example. And any other reason of SQL has to to keep that memory stored by
that query, I dont want it.
Is there a way to release that memory I really dont need my SQL server to keep, without having to restart the SQL server?
and without topping the max memory the sql server uses, since I need my SQL server to use as much as it needs in other tasks(I dont think it needs to hold on to the above query memory used)
Thank You very much.

A query can be resource intensive even if it returns a single row. Generally it is a good idea to set SQL Server MAX memory.
BOL: "Optimizing Server Performance Using Memory Configuration Options
The memory manager component of Microsoft SQL Server eliminates the need for manual management of the memory available to SQL Server. When SQL Server starts, it dynamically determines how much memory to allocate based on how much memory the operating system
and other applications are currently using. As the load on the computer and SQL Server changes, so does the memory allocated. For more information, see Memory Architecture.
The following server configuration options can be used to configure memory usage and affect server performance:
•min server memory
•max server memory
•max worker threads
•index create memory
•min memory per query
The min server memory server configuration option can be used to ensure that SQL Server does not release memory below the configured minimum server memory once that threshold is reached. This configuration option can be set to a specific value based on the
size and activity of your SQL Server. If you choose to set this value, set it to some reasonable value to ensure that the operating system does not request too much memory from SQL Server, which can affect SQL Server performance.
The max server memory server configuration option can be used to specify the maximum amount of memory SQL Server can allocate when it starts and while it runs. This configuration option can be set to a specific value if you know there are multiple applications
running at the same time as SQL Server and you want to guarantee that these applications have sufficient memory to run. If these other applications, such as Web or e-mail servers, request memory only as needed, then do not set the max server memory server
configuration option, because SQL Server releases memory to them as needed. However, applications often use whatever memory is available when they start and do not request more if needed. If an application that behaves in this manner runs on the same computer
at the same time as SQL Server, set the max server memory server configuration option to a value that guarantees that the memory required by the application is not allocated by SQL Server."

SQL query, generating several rows by a value in a field

I am using Oracle database. Imaging I have a table with a row as following
     col1 | col2 | col3
    'Str1' | 'Str2' | 4
The value from col3=4 should generate 4 rows as following:
     col1 | col2 | col3
    'Str1' | 'Str2' | 1
    'Str1' | 'Str2' | 2
    'Str1' | 'Str2' | 3
    'Str1' | 'Str2' | 4
After several hours in front of the screen and stil no luck - how can I create such a select query???

You're mixing up the 'standard' WITH clause and Recursive Subquery Factoring (which NEEDS a UNION ALL) (see: http://docs.oracle.com/cd/E11882_01/server.112/e26088/statements_10002.htm#i2129904).

SQL Query returning no rows, please help!!

I have a table that contains user audits for a particular procedures alongwith the date stamp. Now, I want to list all the procedures not accessed by the users within the last 6 months. Or, all the procedures that have not been used/accessed during the last 6 months.
This is what I am trying but is not returning any rows:
SELECT DISTINCT proc_name,
TRUNC (entry_date)
FROM log_web
WHERE proc_name NOT IN (SELECT proc_name
FROM log_web
WHERE TRUNC (entry_date) > TRUNC (SYSDATE - 180))
ORDER BY 2 DESC
Please advise.
Thank you in advance.

Two possibilities leap to mind.
First, are you sure that there are any prodcedures not accessed in the last six months?
Second, is there a chance that there could be records with a null value in proc_name? If the sub-query used in a NOT IN predicate returns even one null value, the query will return no rows.
Does this return rows?
SELECT DISTINCT proc_name, TRUNC(entry_date)
FROM log_web

But the Output is not the expected one if we see for the PNUM = 000000, the records are displayed
3 times it should be only ones displayed and also for PNUM = 001645156. My Query is why is it displaying
more than once, is there anyway that we can display it only once. Can some please advice me where am making
wrong. Thanks in advance.

But both the output is wrong is there any way that i can get the result set as below, from the above query i can see duplicates
if the PNUM has more SEQ_NUM then it is again doing a cross join i think and hence the result set is coming wrong. The Below
is the expected output. Can some one help me out in getting this. Thanks in advance.

SQL Query to add previous month amount to current month amount

Beginner - Using SQL 2008 R2 - Having a difficult time adding previous month amount to current month amount on a continual running basis. Table fields and example data are:
FunctionID
UnitID
Dateof
Result      YTD
A                   AA           01/01/2014    10             10
A                   AA           02/01/2014    10
20
A                   AA           03/01/2014     15
35
B                  BB            01/01/2014     20
20
B                  BB            02/01/2014     10           30
The YTD field would be a calculated field. I would need to be able start a new YTD in Jan of the next year. Really could use some help and direction on this one. Easy to do in an Excel spreadsheet. Can't seem to get it in SQL. Thanks in advance.

As of 2008 R2 the choices are:
- Self join
- Correlated subquery (in the SELECT or APPLY clauses)
- Cursor
- SQLCLR aggregation function (winner)
The first two options yield a poor performance for tables with considerable number of rows.
Example:
select
    A.*,
    select
        sum(B.Result)
    from
        T as B
    where
        B.FunctionID = A.FunctionID
        and B.UnitID = A.UnitID
        and B.Dateof >= dateadd(year, datediff(year, '19000101', A.Dateof), '19000101') --bofyear
        and B.Dateof <= A.Dateof
    ) as YTD
from
    T as A;

The things get easier from SS 2012 with the enhanced OVER clause (introduction of window frame extent).
select
    sum(Result) over(
    partition by FunctionID, UnitID, year(Dateof)
    order by Dateof
    rows between unbounded preceding and current row
    ) as YTD
from
    T;

Please advice as soon as possible as this is a production problem
ORG_GRP_I grn_n ED_EFF_m (timestamp) ED_END_M OFV
1 999 01-Jan-06 1 03-Aug-06 0 0
1 999 28-Jul-06 0 04-Aug-06 1 0
1 999 04-Aug-06 1 04-Aug-06 1 0
1 999 04-Aug-06 0 6.08
This query is giving no rows returned,even though there is data in database
SELECT NVL(OFV,0)
FROM audit_data ag
WHERE ag.ORG_GRP_I = 1
AND ag.GRN_N = 999
AND (ag.ED_EFF_M,NVL(ag.ED_END_M,SYSDATE)) IN (SELECT MAX(ED_EFF_M),MAX(NVL(ED_END_M,SYSDATE))
FROM audit_data ag2
WHERE ag2.ORG_GRP_I= ag.org_grp_i
AND ag2.grn_n=ag.grn_n
AND To_Date(To_Char(ag2.ED_EFF_M,'MM/DD/YYYY'),'MM/DD/YYYY') <= TO_DATE(TO_CHAR('08/04/06','MM/DD/YYYY'),'MM/DD/YYYY')
AND To_Date(To_Char(NVL(ag2.ED_END_M,SYSDATE),'MM/DD/YYYY'),'MM/DD/YYYY') >= TO_DATE(TO_CHAR('08/04/06','MM/DD/YYYY'),'MM/DD/YYYY'));
This query is giving value 6.08, when made type conversions.
what wrong with the above query.please advice
SELECT NVL(OFV,0)
FROM audit_data ag
WHERE ag.ORG_GRP_I = 1
AND ag.GRN_n = 999
AND (to_date(to_char(ag.ED_EFF_M,'mm/dd/yyyy'),'mm/dd/yyyy'),NVL(to_date(to_char(ag.ED_END_M,'mm/dd/yyyy'),'mm/dd/yyyy'),SYSDATE)) IN
(SELECT MAX(to_date(to_char(ED_EFF_M,'mm/dd/yyyy'),'mm/dd/yyyy')),MAX(NVL(ED_END_M,SYSDATE))
FROM audit_data ag2
WHERE ag2.ORG_GRP_I= ag.org_grp_i
AND ag2.grn_n=ag.grn_n
AND To_Date(To_Char(ag2.ED_EFF_M,'MM/DD/YYYY'),'MM/DD/YYYY') <= TO_date('08/04/2006','MM/DD/YYYY')
AND To_Date(To_Char(NVL(ag2.ED_END_M,SYSDATE),'MM/DD/YYYY'),'MM/DD/YYYY') >= TO_DATE('08/04/2006','MM/DD/YYYY'));

In the second query you convert a string to a date correctly using TO_DATE(string,date format)
In the first query you try to make a char of something that already is a char, e.g. TO_CHAR('08/04/06','MM/DD/YYYY').
The TO_CHAR functions expects either a number or a date as its first parameter. That's why it's giving you a ORA-01722.
