Repeat a Select statement

Hello

I run a query on a very large table, something like

SELECT (SOME SUBQUERIES ON THE MOVEMENT), (SOME MORE SUBQUERIES), ().
MOVEMENTS MV
WHERE MV. EFFECTIVE_DATE > = START DATE
AND MV. EFFECTIVE_DATE < END DATE
AND... CERTAIN OTHER CONDITIONS

My problem is that the runtime grows exponentially with the length of the interval between SOME_START_DATE and SOME_END_DATE.
So, for an interval of a month, it takes a minute but for a period of two months, that he just keeps going, I ran out of patience after about 15 min.
I want to start for a long interval of the year so I was wondering if there is a way to repeat the select statement in a list of dates in PL/SQL?
Or maybe a different approach?

Would appreciate some advice

Thank you

Yes!
First: Join the tables instead of asking the database to do subqueries for each line you want from the MOVEMENTS.
Second: Gives us a small input and outputs expected, so we can work out a solution.

Several Select statements fill Horizontal

Hello
I wonder how to fill these three instructions select a line, horizontal. The data does not correctly from my code below.
The first statement returns 4 rows
The second statement returns 27 lines
The last third statement returns 31 rows
My problem is that when the code below runs more than 500 rows are returned. What I do wrong to not fill the
results.
Example of how the data should look like, I don't understand the third declaration for space.

Hello

The best is probably the cross join the demo_customer table will be a table that has 3 lines (so that the demo_customers data can be repeated up to 3 times, that the conditions are met), assign a number line (r_num) for the data replcated and pivot so that data on a line by r_num like that :

     SELECT     LEVEL     AS n

This has only to make a pass through the demo_customers table, so I think it will be faster to do a self-join, where you have to make a separate pass mark for each criterion.
Make sure that the analytical got_rnum.r_num ORDER BY clause contains all the columns that have been in your original GROUP BY, even if you don't really care to their order. The main request will make a GROUP BY r_num, so including the columns in this clause ORDER BY to include in the GROUP BY.

The problem with the full outer join is that you still do not put join conditions after the individual tables. After that the each keyword JOIN there will be a table name or a alias and immediately after that must come the key word WE followed by a coindition to join.
I made a mistake earlier: when full outerer joining several tables, would better meet you each new table in each of the previous tables, because it is unclear which of these tables may be missing due to the outer join. In other words, the join condition for f had better be:

ON           f.r_num = COALESCE (d.r_num, e.r_num)

because d.r_num or e.r_num could be NULL, because the outer join.

SQL select statements

Hey everybody,

First of all, Yes, I searched through the 8.5 database schema guide. As I went through the scheme, I've developed some ideas on how to collect the data you want. However, if someone has already developed or found the SQL statements (which I'm sure that someone already has) it would help by reducing to the minimum of the buggs in my data collection program.

All these statistics must be grouped by CSQ and selected for a certain time interval ( and ). That is, levels of 1 hour. I have no problem to get a list of results and then perform v.f. to achieve the desired final result. Also, if I need to run several select statements for tables of essentially two join, please include two statements. Finally, I saw the RtCSQsSummary table, but I need to collect data for the past, not at this time.

1 total calls presented by the CSQ

2. total number of calls answered by the CSQ

3 total number of calls abandoned by the CSQ

4. percentage of calls abandoned by CSQ (if it is not stored in the database, I think: /)

5. average abandon time in seconds (if it is not stored in the DB, I think: sum () /)

6. service level - % calls answered in 90 seonds by a set of skills (I have seen metServiceLevel in the ContactQueueDetail table; however, I need to find how to configure this threshold for application)

7. average speed of response by CSQ

8 average conversation by CSQ calls

9. the aggregates connected full-time resources or agents CSQ

10. resources/agents of CSQ ready time

I realize that some of them should be easy to find (as I always am search in the guide of db schema), but I was reading how a new record is created for each step of the call so I could easily see how I could get inaccurate information without properly developed select statements.

Any help will be greatly appreciated.

Brendan

Brendan,

I read your message very well.

You have the schema of database with tables and description. each table has its associated tables (connected with primary and foreign keys). I think you should start the tables to determine what you need.

Cisco uses the stored procedure to prepare the reports. the stored procedure is 'sp_csq_interval' to create the report.

uniol all in the select statement

Hi I have a situation where I have to return the value based on the if statement, is it possible to put union all in the select statement
My use case is
IN the column State
If column01 > 0 to condtion 't'
IF column02 > 0 that the condition of 'Y '.
Condition IF COLUMN03 > 0 THAN 'w '.
If COLUMN04 > 0 that the condition of "Z".
Select 't'
TableName
where column01 > 0
Union of all the
Select "y".
TableName
where column02 > 0
Union of all the
Select 'W '.
TABLENAME
WHERE COLUMN03 > 0
I have what it takes to show value as it
EmpName, condition, empno
Jerry, T, 0158754585
TOM, Y, 0054789568
Am in oracle database 11 g 2

Yes you can put all THE UNION here

Select empname, 't' State, empno from tablename where column01 > 0

Union of all the

Select empname, 't' State, empno from tablename where column02 > 0

Union of all the

Select empname, condition of "W", empno FROM tablename WHERE COLUMN03 > 0

Union of all the

Select empname, condition of "Z", empno FROM tablename WHERE COLUMN04 > 0

and if you are looking for how to remove duplicates because your line might have satisfied all the conditions and my happen 4 times in your result set, you just need to give them an order and filter it.

For example, you want this

If column01 > 0 to condtion 't'

ELSE IF column02 > 0 that the condition of 'Y '.

Another condition of THAN > 0 IF COLUMN03 'w '.

otherwise if COLUMN04 > 0 that the condition of "Z".

Select empname, condition, empno, in

(

Select a.*, row_number() over (partition by empno arrested by myorder) rn

Of

(

Select empname, 't' State, empno, 1 myorder tablename where column01 > 0

Union of all the

Select empname, 't' State, empno, 2 myorder tablename where column02 > 0

Union of all the

Select empname, condition of "W", empno 3 myorder FROM tablename WHERE COLUMN03 > 0

Union of all the

Skip and capture the Oracle SQL record dirty in a select statement

Hello
I have the Oracle Oracle 11.2.0.4 database when I run a select query.
Question:
10 columns have given Date format. When I try to execute this query into a FROG he says, a month not valid. Since the records are billion in nature, I am not able to know which line has this problem.
Is there a way I can capture the failed row and add it to other tables and continues with the select statement regardless of this error

OK, you have several TO_DATE functions fed a string that is built on the fly. At least part of the time, the chain that is built does not match the date format mask used.

For example:

TO_DATE (SUBSTR (TO_CHAR (SQ_W_PURCH_CYCLNS_ORA. LAST_SUBMITTED_ON_DTTM_WID), 0, 8). » -'|| SUBSTR (TO_CHAR (SQ_W_PURCH_CYCLNS_ORA. (LAST_SUBMITTED_ON_DTTM_WID), 9, 6), "YYYYMMDD-HH24MISS")

"SQ_W_PURCH_CYCLNS_ORA. LAST_SUBMITTED_ON_DTTM_WID' does not have a string where characters 5-6 are in the range 01-12. You'll have to do an analysis on this column. From its data and how that is managed by to_char. What ARE the data type of ' SQ_W_PURCH_CYCLNS_ORA. LAST_SUBMITTED_ON_DTTM_WID' and what is a typical value?

As others have said, this is simply an impossibility for a column of a table to actually have invalid month (or day, or year, or hour or minute or second). ONLY, you get this error during the conversion of a string to a date with the TO_DATE function.

SELECT statement

Dear all,
We hope that all are doing well.
I need your help once again, my requirement is to write a trigger for "select statement" on a particular table, the name and the date of the user who executed.
your help will be appreciated.
Thanks in advance.
OS: RHEL 6.1
DB: 11.2.0.3

Trigger is not possible on the SELECT statement, you can audit only by database.

Or can save your select queries to application level.

Need help with the use of GROUP BY in a select statement UNION

I am writing a query that allows to combine a legacy system that interfaces it is trial balance in the Oracle of R12 GL. It was only meant to continue for a month or two, but it is likely to continue for 6 months. Please Auditors Auditors, to provide proof that the system is in balance with Oracle GL. By my verification requirements, I need to make a full reconciliation from the month of conversion (life in the amount of date), then PTD for each month.

The legacy account is placed in attribute1 on the lines of the journals. Uses of the old system balancing segments that are also used on the platform in Oracle for this division, i.e., Procure-to-Pay has been cut over Oracle, but not everything yet. So, I can't count on the GL_BALANCES table for the info, I get from the JE_LINES.

My problem is not the only request for the month. But when I try to combine the queries with a Union, to aggregation of each measurement period in its own column, the group is necessary after each selected instruction rather than allowing me to put at the end of the UNION. (When I put the group by at the end of the UNION, I have the 'not one group' function)

So I get duplicate for each month of discrete measure accounts. When I duplicate in my Oracle database accounts, I can't count on the VLOOKUP function in excel to exactly match an account of inheritance. I know there are more sophisticated ways to provide this output, but I'm hoping to get this info in a simple query.

Thank you in advance for any advice you can provide

Example of data output (the goal for me is to get the two rows to appear as one based on common points on the LEGACY_ACCOUNT and the ORACLE ACCOUNT

The LEGACY ACCOUNT	ORACLE ACCOUNT	JUN_15	JUL_15	AUG_15	SEP_15	OCT_15	NOV_15	DEC_15

Here is a simplified version of my code that returns both records.

How to INSERT a SELECT statement with a GROUP BY clause on a table with an IDENTITY column?

n an application, I intend to truncate and insertion on a 12 c Oracle database, but have found this problem with a IDENTITY column. Even if the INSERT... SELECT statement works on most SELECT uses I tried, if this statement was also a GROUP BY clause, it does not work, delivering a "ORA-00979: not a GROUP BY expression ' complaint. Some examples of code:
```
create table aux ( owner_name varchar2(20), pet varchar2(20) );  
insert into aux values ('Scott', 'dog'); 
insert into aux values ('Mike', 'dog'); 
insert into aux values ('Mike', 'cat'); 
insert into aux values ('John', 'turtle');  


create table T1 (
  id number generated always as identity,
  owner_name varchar2(20),
  pet_count number ); 
select owner_name, count(*) as pet_count from aux group by owner_name; -- works just fine
insert into T1 (owner_name, pet_count) select owner_name, count(*) as pet_count from aux group by owner_name; -- doesn't work
```
The select statement works by itself, but it fails as an INSERT... SELECT statement.
Appreciate the help!

Looks like a bug. You must open the SR with Oracle. Meanwhile, you could materialize select:

SQL > insert into T1 (owner_name, pet_count)
2 with t as (select / * + materialize * / owner_name, count (*) as pet_count to the owner_name group)
3. Select owner_name, pet_count t
4.

3 lines were created.

SQL > select * from t1;

ID OWNER_NAME PET_COUNT
---------- -------------------- ----------
1 John 1
Scott 2 1
3 Mike 2

Keep in mind index THAT MATERIALIZE is undocumented.

DDL lock on the object in a SELECT statement?

Environment:
Oracle 11.2.0.4 EE on Solaris
My client called me when she was trying to create a new index on a table and the process was just hanging. Also, she was not able to DELETE an existing index on the same table, which deal with hang them as well.
After reviewing the advice DBA_DDL_LOCKS, I found a DDL lock on the target of the index table.
The DDL lock is held by a process doing a SELECT on the table and this process worked for several hours.
There was no entry in V$ LOCKED_OBJECTS for the table.
I don't know, yet, what other operations prior to the SELECT statement in the offending process, I have not heard of the user yet.
I realize a DDL lock is placed on objects to prevent changes while specific operations are directed against this object, i.e. the DROP, UPDATE, compile the PACKAGE, etc.
Question: Is a select also place a DDL lock on a table at a level that would avoid a new index is created or an existing index having fallen?
Thank you very much for your comments!
Any reference to the resolution is greatly appreciated.
I searched some Concepts Developers Guide, SQL, even Google reference Guide.

Easy enough to show that it is not.

Session1:
```
SQL> create table foo(bar number);     

Table created.                         

SQL> insert into foo values(1);       

1 row created.                         

SQL> commit;                           

Commit complete.                       

SQL> variable x refcursor
SQL> variable a number
SQL> begin
  2  open :X for select bar from foo;
  3  end;
  4  /                                 

PL/SQL procedure successfully completed.
```
Session 2:
```
SQL> drop table foo;

Table dropped.     
```
Note that I was able to remove the table even if select is still 'in progress' - the cursor is open.

If you really want to blow your mind, go back to the session 1:
```
SQL> begin
  2  fetch :X into :a;
  3  end;
  4  /                                

PL/SQL procedure successfully completed.

SQL> print a                          

         A

         1

The picture has gone, but I can always look for him. However, try again:
```

ORA-00604: error occurred at recursive SQL level 1
ORA-00942: table or view does not exist          
```
Note that the forum software is stupid. is: followed by x. seems it's really important to have a smiley to lovey eyes in a technical forum.

Edit - and when you format the SQL code, it is removed completely and render invisible... silly.

I edited my code to use: X and the problem disappeared...

How to format the output of a .sql script that has select statements.

Hello
I have a .sql script which is having several select statements. Each Select statement is to have hundreds of Table columns.
When we run the .sql script, we are unable to read the output.
Please let know us the commands that we include for better readable output format.

You work with the lin standard set 80.
Increase this setting to set lin 3000 or more.

SELECT statement in the script output window

Hello
SQL Dev 4.0.3
is it possible to include select statements from the command run the Script in the Script Output window?
Is the result in the window:
Select 1... ;
results
Select 2... ;
results
Joop

try to put "set echo on" (without the quotes) as the first line and make sure that you use F5 to run the script... like sqlplus.

executes a select statement, each minute for half an hour

Hi all
I want to run a SELECT statement on a table every minute for half an hour.
Something like this:
Begin
Do all the 1 minute for 30 Min
Select col1, col2 from mytable
End
I thought about PL/SQL loop. But no matter what example with timekeeping.
I don't care?
Thank you and best regards.

Hello

As John said, you can use DBMS_SCHEDULER for this. That being said, you just can't run a query and do nothing with its result. You must do something with it.

Here is an example showing how to create a task that runs every minute for a total of 30 min

BEGIN

DBMS_SCHEDULER. Create_Job (job_name-online 'MY_JOB',

job_type-online "PLSQL_BLOCK."

job_action => ' DECLARE val1 number; val2 number; BEGIN SELECT 1, 2 INTO val1, val2 FROM DUAL; END;',

start_date => SYSDATE,

End_date => SYSDATE + 30 /(24*60),

repeat_interval => ' FREQ = MINUTELY ",

auto_drop => TRUE,

enabled-TRUE online

);

END;

/

It will start immediately and end 30 minutes later (it will be automatically abandoned). As you can see, the result of the query is placed in the variables. Thus, this work is useless.

SELECT statement to return a type in Oracle objects

Hi all, I have created a small system for Uni using oracle objects and types. I have a table person with type of seller under the person table and the type of claimant to the title of the person table.

Happy that you have your code working but that was not my point

It comes to you providing us with the correct instructions to actually run the test case and help you efficiently.

Regarding your last question, use the function of REGAL to caster level being superior in one of its subtype.

for example

SQL> select person
  2       , treat(object_value as applicant_t).aSurname as surname
  3       , treat(object_value as applicant_t).aForename as forename
  4  from person_tab
  5  where object_value is of (applicant_t) ;

a simple select statement once again

What is the meaning of the one below select statement, pay attention to (sysdate + 1.1)
Select (sysdate + 1.1) of the double

Hello

a_cute_person wrote:

Lo, seriously, dude you do not make to_char thing, when I select sysdate, sysdate + 1.1 double I see clearly there is time change, I wanted to know what the weather has changed when I do sysdate + 1.1, and why there is no change in time sysdate + 1. hope you have the hand on what I ask

Understand this:

When you add 1 to SYSDATE, a full day is added. So, if the current time i.e. SYSDATE is January 22, 2015 16:55 ', by adding 1, it will be named January 23, 2015 16:55 '. Simple.

But, 1.1 means one-tenth day and fractional hour comes in picture.

Yes, day 1.1

= 1 + 1/10 of the next whole day

= 24 * 60 * 60 seconds + (1/10) * 24 * 60 * 60 seconds

and here the time portion changes.

HTH.

using the function - how to use the values of the input variables on the table select statement names

Hello community, I have a problem when creating a function. The purpose of this function is to check the table of weather gave yesterday or not. We must check this on different tables on different sachems. We are creating a function with input variables.

How to use the values of the input variables on the table select statement names?

Hello

Here's a way you can use dynamic SQL statements for this task:

CREATE OR REPLACE FUNCTION IS_YDAYDATA_TO_TABLE

(

in_schema IN VARCHAR2,

in_tablename IN VARCHAR2,

in_datefield IN VARCHAR2,

in_first_date DATE DEFAULT SYSDATE - 1,.

in_last_date DATE by DEFAULT NULL

)

RETURNS INTEGER

AS

-IS_YDAYDATA_TO_TABLE returns 1 if in_schema.in_tablename.in_datefield

-contains all the dates in the in_first_date of the range through included in_last_date

- and it returns 0 if there is no such lines.

-If in_last_date is omitted, the search only the data on in_first_date.

-If in_first_date is omitted, it defaults to yesterday.

-Time parts of the in_first_date and in_last_date are ignored.

-Declaring variables

sql_txt VARCHAR2 (1000);

v_is_true INTEGER.

BEGIN

sql_txt: = 'SELECT COUNT (*).

|| 'FROM ' | in_schema | '.' || in_tablename

|| 'WHERE ' | in_datefield | ' > =: d1'

|| «AND» | in_datefield | '< >

|| 'AND ROWNUM = 1';

dbms_output.put_line (sql_txt |) '= sql_txt in IS_YDAYDATA_TO_TABLE"); -For debugging

Sql_txt EXECUTE IMMEDIATE

IN v_is_true

With the HELP of TRUNC (in_first_date) - d1

TRUNC (NVL (in_last_date

in_first_date

)

) + 1 -- d2

;

RETURN v_is_true;

END is_ydaydata_to_table;

/

DISPLAY ERRORS

If you must use dynamic SQL statements, put all the SQL statement in a single string variable, such as sql_txt in the example above. In this way, you can easily see exactly what will be executed. Comment out the call to dbms_output under test is completed.

Try to write functions that will address not only the question that you have now, but similar questions that you may have in the future. For example, now that interest you only to the verification of the data of yesterday, but later, you might want to check another day or range of days. The above function combines the convenience of a function simple (looks like yesterday data if you don't tell him otherwise) with the power of a more complex function (you can use the same function to check any day or range of days).

Repeat a Select statement
