How to concatenate two sql statements?

Hello

How can I combine the following two sql statements so that the result of a line of the first statement appears before the lines of my second sql statement. The reason I need it is to order the lines correctly.

Select the username, id
some abusers
where id = 0

Select the username, id
some abusers
where id! = 0
order by username

Thank you

You should ask in the forum of the Apex:

How to combine towing sql statements.
Hi all

I try to combine the two sql statements. but it is giving error 907, I can't stand no less. Please correct me if am wrong.
Here's my query

Select a.A1, b.C1, a.B1 in)
(select C1, sum (s.amount_sold) cust_first_name

I found two [a start and closing] and additional fasteners - from parentheses after FROM and closing introductory "order by".

Try this:
```
SELECT a.A1, b.C1, a.B1
  FROM
             (  SELECT cust_first_name C1, SUM (s.amount_sold)
             FROM customers c, sales s

How to execute a SQL statement that is stored within a SQL Table

Hello
If someone please help me with the following problem I would be eternally grateful
I have a SQL statement that is stored inside a certain SQL table, I want to use this SQL statement inside my PL/SQL procedure.
Thought a simple solution was to get the SQL statement in a table, and then run it, but how could I do so exactly with PL/SQL? I only started to play with PL/SQL in the last days.
Thanks in advance!
This is what it looks like more or less:

Display result for:

---------------------

SELECT TRIM (OBJ_VALU_TXT)

OF OBJ_VALU_DOC

WHERE TYPE_OBJET = 'FLD '.

AND OBJECT_CODE = 15443

AND OBJ_VALU_CD = 'CAB '.

ORDER BYDOC_SEQ_NO

00001

------------------------------------------------------------------

SELECT

VALUE (MAX (RECEIPT_NO) + 1,: OUT-COMP-FACTOR)

THE FRONT DESK

WHERE (RECEIPT_NO BETWEEN

(: OUT-COMP-FACTOR AND: OUT TO A NUMBER) OR

(RECEIPT_NO >: OUT-COMP-FACTOR AND)

(: OUT-TO-NUMBER = 0)

Here's a demo of your condition.

create table t (col1 varchar2 (200));

table created

insert into values t ('select * from double ');

1 row inserted

declare
v_col varchar2 (200);
v_val varchar2 (200);
Start

Select col1 in t v_col;

run immediately v_col in v_val;
dbms_output.put_line (v_val);
end;

-----
X

Use in the clause, you can use as many variables as needed. But the basic approach remains the same.

But storage in DB SQL is not an efficient design.

How to run grid sql statements
Hello

I would like to run some of the grid control sql statements as tablespace freespace check.

Grid options could there be to execute the sql statement?

If so, how to set up the output of the sql for E-mail

Please I need your suggestion to proceed.

Version of the grid: 10.2.0.5.0
Platform: Sun

Thank you.
Hello

no need to run the sql statement of the grid, instead of that you can configure the threshold values.

for example, if your tablespace capacity 85% complete and then he will send you the email alert that you configured in notifications.

you will find on the home page - bottom of the page - > manage settings...

How to execute the SQL statement in the Application Module
Hi people
I´d would like to know how I can execute a SQL statement like "remove user" in the Module to request... prepareSession method...
I m using Jdev 10 with ADF Faces
Thank you
This is possible, but you should think twice about it.
If this can be done with an EO/VO do in this way.
If you can't do it with an EO/VO you can yourself the DB operation (ApplicationModule.getDBTransaction ()) and use a call of createStatement (...) do what you want.

How to execute the sql statement in the file beats?
I want to execute after the statement
C:\ > sqlplus/nolog
SQL > conn scott/tiger
SQL > select * from tab;

I know I can achieve it following test.bat and testdb.sql file
test.bat is:
sqlplus/nolog @testdb.sql

TestDB.SQL is:
Conn scott/tiger
Select * from tab;

Now I don't want to use the sql file, I want only use bat file, as follows:
test.bat is:
sqlplus/nolog
Conn scott/tiger
Select * from tab;

When I run test.bat, I find only one sqlplus /nolog execute statement, do not execute other statements.
(1) I want to know if there is a method to run the SQL file by fighting without a sql file? How to make it happen?
(2) if I call the sql file, how to hide the password of user? Because I don't want other people to know scott password, if I use conn scott/tiger in testdb.sql, other person can see testdb.sql and the password. Is there a good way to avoid?

Thank you!
It works a bit different in Windows. Create a file is like this:
```
(
  echo conn scott/tiger@orcl
  echo spool c:\temp\list.txt
  echo select sysdate from dual;
  echo spool off
  echo exit
) | sqlplus -s -l /nolog

How to run an SQL statement
Dear friends,

As I recently started working with SQL more, I realized that my opinion on this has changed.
```
select first_name, last_name
from personal_details
```
and
```
select first_name, last_name
from personal_details, education_details
```
and
```
select first_name, last_name
from personal_details a , education_details b
where a.id =b.id
```
and
```
select first_name, last_name
from personal_details a , education_details b
where b.id =a.id
```
is it different? or make the same result?

Won't return the same result.

Just started to wonder, how it actually works of in.

Can anyone shine some light on this issue?

Thank you.

By default, I think that oracle starts executing the last where condition and so queries can take different time, depending on which is the primary key, or if any column index created on this subject.

This statement is almost always wrong. Oracle evaluates what query condition is the best to run first. This is done by the optimizer cost based using statistical information about the tables, columns and the indexec on these columns. There had been questions back in the day Oracle 7 and the RBO (rule based optimizer) where the order in the clause from and where clause was important. But in general, do not care anymore to this topic.

Hello

If tab1 and tab2 will always be exactly 1 row of each, then you can make a cross join:

SELECT tab1.a1 - tab2.a2 AS a_dif

, tab1.b1 - tab2.b2 AS b_dif

, tab1.b1 - tab2.c2 AS c_dif

OF tab1

CROSS JOIN tab2

;

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.

Explain, using specific examples, how you get these results from these data.

Always say what version of Oracle you are using (for example, 11.2.0.2.0).

How to generate the SQL statement

Here is the table and the data, and I did the solution using a pl/sql cursor.
This is possible in a SQL statemnt?

create the table TEMP_DISTINCT

B_ID NUMBER not null,
C_VAL VARCHAR2 (30)
)

INSERT INTO TEMP_DISTINCT(A_ID,B_ID,C_VAL) VALUES(111,2222,'One')
INSERT INTO TEMP_DISTINCT(A_ID,B_ID,C_VAL) VALUES(111,2222,'Two')
INSERT INTO TEMP_DISTINCT(A_ID,B_ID,C_VAL) VALUES(112,2222,'Three')
INSERT INTO TEMP_DISTINCT(A_ID,B_ID,C_VAL) VALUES(112,2222,'Four')
INSERT INTO TEMP_DISTINCT(A_ID,B_ID,C_VAL) VALUES(112,2221,'Five')
INSERT INTO TEMP_DISTINCT(A_ID,B_ID,C_VAL) VALUES(112,2221,'Six')

declare
vorgid varchar2 (30);
CUR cursor is
Select distinct A_ID, B_ID from TEMP_DISTINCT
order by A_ID, B_ID;
Start
for the curs in news
loop
Select C_VAL
in TEMP_DISTINCT vorgid
where curs. A_ID = A_ID
and curs. B_ID = B_ID
and rownum = 1;

dbms_output.put_line (curs. A_ID | ' : ' || curs. B_ID | ':' || substr (vorgid, 1, 22));
end loop;
end;

Output

112: 2221:Five
112: 2222:Three
Hello

When you use ROWNUM directly on a table or a set of view or a result that is not an ORDER BY clause, results are for an indefinite period, in other words, there is no guarantee that you will get the same results every time that you run the query, even if the table has not changed.

The ROW_NUMBER analytic function can be used instead of ROWNUM. ROW_NUMBER can be calculated several different sequences (on different partitions of the result set) at the same time, like this:
```
WITH    got_rnum    AS
(
    SELECT  a_id
    ,       b_id
    ,       c_val
    ,       ROW_NUMBER () OVER  (PARTITION BY  a_id, b_id
                                 ORDER BY      ROWID
                                )   AS rnum
    FROM    temp_distinct
)
SELECT  a_id
,       b_id
,       c_val
FROM    got_rnum
WHERE   rnum    = 1
;
```
When you use ROW_NUMBER, you have to ORDER SOMETHING. In a very small table, like the sample, arbitrary results could come in the ROWID in your PL/SQL code order, so I used "ORDER OF ROWID" above. I could have used a constant, for example "ORDER OF 0.

You cannot change anything in your SQL query to exclude these lines.
These lines refer to the client you are using i.e. SQL * more and have nothing to do with the SQL language as such.

You could put all of these SQL * more commands in a script file and run this SQL script file *, as shown below:

test@ORA10G>
test@ORA10G> -- show contents of the script: c:\test.sql
test@ORA10G> host type c:\test.sql
set feedback off
set trimspool on
set heading off

select ename from emp;
spool off
set echo on
set heading on

How to get the create view sql statement
I have a technical problem

There is a view in the database, for example "topstudentsview" and sql statement is ' select * student where scores > 90;

My question is how to get the sql statement of the view. I want to get the sql statement in the topstudentsview

Is the equivalent in MS Sql

sp_helptext 'topstudentsview '.

How in Oracle?

Thank you

Simple answer: use a tool. Almost every development tool will give you an option for this requirement.

In Oracle SQL Developer (free), it's as simple as:

Connect to the database with the user and click on "views".
Select the appropriate view, and then click the SQL tab.
