Help Newbie SQL

Hello

Someone understand me can explain why this SQL:

SELECT
R.r_ein FM, R.r_qtr QTR, S.s_class_title CLASS.
COUNT (CASE WHEN S.s_class_title = "Static"
THEN S.s_class_title
) AS static.

COUNT (CASE WHEN S.s_class_title = 'Dynamic'
THEN S.s_class_title
) AS dynamic.

COUNT (CASE WHEN S.s_class_title = "Strength of materials"
THEN S.s_class_title
) AS som

The REQUEST R, student S
WHERE R.r_id = S.s_request_id
AND (R.r_qtr = 'FY15Q4') OR
R.r_qtr = "FY15Q3") OR
R.r_qtr = "FY15Q2") OR
R.r_qtr = "FY15Q1")
)
GROUPING SETS (R.r_ein,(R.r_ein,S.s_class_title,R.r_qtr), NULL) GROUP
ORDER BY R.r_qtr, S.s_class_title

generates "ORA-00905: lack of keyword" when it is executed?

I'm counting the number of these classes of all others in the table.

Thank you

You need at the end of the CASE...

Thank you for taking your time to help I appreciate all of your comments I get this can improve my SQL because I am in it and I want to my class of ace

I let down all the tables and copy them and paste in oracle and see what I get atm cause I get the same error, but cannot determine where I'm wrong

Following the advice I got from my last topic I created now my tables and now I want to fill it with my data but I get an error

Here is my sql command complete. Since the last time, I learned that a foreign key can be implemented in a single table and cannot be reproduced

to work around this problem, I changed my foreign key as you can see in "fkone". But why make me errors when trying to add information

I want to say that I have not gotten errors in the first two tables until I have "hurt / not understand."

Help on SQL Pivot

Hi gurus,
I have req where I need to make the comparison between the Bill of trial ordinary bill vs. I need to get the test of the previous months and the latest current_month and 2 months of regular bills. Here are the th sample data.

Account # Invc # Start_Date end_date regular_Amoun t Trial_Amount
1233456 26470000 June 1, 2013 July 1, 2013 $19 27
1347589 26470000 August 1, 2013 current_date $45 67
1115756 26470000 may 1, 2013 July 1, 2013 $39 27
This is the desired output
Account # Invc # June 2013, July, 2013 August 2013
1233456 26470000 $39 19 $ $67
Any contribution is appreciated

Hello

Depending on your needs, here's a way:

WITH got_month_num AS

(

SELECT account # invc #, regular_amount, trial_amount

TRUNC (MONTHS_BETWEEN (start_date

ADD_MONTHS (TRUNC (SYSDATE, 'MONTH'),

- 3

)

)

) AS month_num

FROM table_x

WHERE the arguments start_date > = ADD_MONTHS (TRUNC (SYSDATE, 'MONTH'),-2)

AND start_date< add_months="" (trunc="" (sysdate,="" 'month'), ="">

)

SELECT MIN (CASE WHEN month_num = 2 THEN accountt # END) AS account #.

invc #.

SUM (CASE WHEN month_num = 1 THEN regular_amount END) AS month_before_last

SUM (CASE WHEN month_num = 2 THEN regular_amount END) AS last_month

SUM (CASE WHEN month_num = 1 THEN trial_amount END) AS this_month\

OF got_month_num

GROUP BY invc #.

;

It would take to get the columns as AUG_2013 dynamic SQL alias. Your front end can help with that. In SQL * Plus, for example, you can use substitution variables.

I hope that answers your question.
If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
Point where the above query is incorrect results, and explain, using specific examples, how you get the right result of data provided in these places.
Always say what version of Oracle you are using (for example, 11.2.0.2.0). In this problem, what front-end you use (for example, SQL * Plus version 10) may also be important.

Help with SQL Query (Subselects)
Hello community,

IAM a new Member in this forum. The first excuse my English, my native language is German.
In my workplace, we have a great Orcle Database 11 g with 30 different tables for production control issues.
I try to get a couple of different information from the database, so I started with SQL of the query, but for this problem, I wasn't able to write a query to work.

In this case, I have 2 tables:
Table 1:
ID; ORDER_NR; DESCRIPTION; CREATE_DATE
1; A500236; CLEAN HOUSE; 20/02/2012
2; A623555; REPAIR CAR; 10/01/2012
3; A866944; MAINTAIN EQUIPMENT; 11/02/2012

Table 2:
ID; ORDER_NR; WO_STEP; STEP_DATE; EMPLOYEE
1; A500236; A; 21/02/2012; W0010
2; A500239; F; 21/02/2012; W0010
3; A500239; S; 22/02/2012; W0027
4; A500239; R; 23/02/2012; H0034
5; A500239; U; 25/02/2012; L0099
6; A263555; A; 15/01/2012; G0009
7; A263555; C; 17/01/2012; S0039
5 V A263555; R; 18/01/2012; K0059
9; A263555; U; 19/01/2012; A0048
10; A866944; A; 13/02/2012; H0034
11; A866944; B; 13/02/2012; L0035
12; A866944; G; 17/02/2012; D0084
13; A866944; U; 23/02/2012; S0039

And the result of my query should look like this:
ORDER_NR; DESCRIPTION; CREATE_DATE; A_STAT_AGE; R_STAT_AGE; U_STAT_AGE
A500236; OWN HOME; 20/02/2012; 5; 3; 1
A623555; REPAIR CAR; 01/10/2012; 42; 39; 38
A866944; MAINTAIN EQUIPMENT; 11/02/2012; 15; 4; 3

The age of my query result should be calculated from the date of the creation of the order.
I would like to know 2 things, one is how old was the order when they reached this status, R and U.
The second, that is, how long did you order remaining on A stat, R and U (and if possible all the others too)
It can happen that not every order reaches every State, so he ca go directly from A you in this case I want to display a generic character in this row/column

I hope you all know what I mean and what result to expect.

Thanks for your help.

Hi Frank,.

I thank you for your professional response and excuse my non-professional way to clarify my question.
I have now already read and understand how to ask good questions, but is there an easy an inexpensive way to run a database on my computer at home?

You can download the Oracle database from this site. The Express edition is easier to install. It lacks a few features that the Enterprise edition (for example, partitioning table and safety of level line), but most of the things work in all editions of Oracle.
All editions are free if you do not use them for Production applications. Of course, at this price (or lack thereof), you get Oracle support.

I have already noticed that the syntax SQL for Oracle differ from other DBMSS.

Yes and some features are different in different products.

Your query works perfectly, thank you.

Now I want to refine my (your) query, is there a way to display a range of day within 1 day? As 0.5 day to half a day between two State timestamp.

Of course, you can do it. After the exact output desired of the sample data that I posted. If the sample data do not show what you need to do, then after a few different examples of data that makes.

My table contains the Date and time in a row, I forgot to mention that.

After a CREATE TABLE statement. I was guessing a lot of things that may be important. For example, I assumed you were using a DATE for date and time column. So it is only reasonable to do so, but maybe it's not what looks like at your table.
I tried something like this:
```
SYSDATE - MIN ( CASE
                    WHEN  t2.wo_step = 'A'
              THEN  t2.step_date
          END
           ) AS Age_A
```
But it gives me an error of arithmetic overflow and not die difference in the Date and time or days with decimal friction.
There are only about 5.4 million possible days with DATEs of Oracle. Is only 7 digits and Oracle can treat approximately 39 numbers without overflow errors, so I don't see how this can happen if t2.step_date is really a DATE. This is an example of why you need to publish a CREATE TABLE statement.

Where clause ' where 1 = 1 ' help with SQL tuning
Hello Tuning specialists,.
It is useful to use ' where 1 = 1 ' and then type all joins and conditions in the statements 'AND' of the SQL when writing SQL queries. I would like to know if it helps with the writing queirs this way SQL query performance.

Thanks in advance.

He has No. performance impact.
It is done when building dynamic SQL, so each sentence can start with AND
