Using ROWNUM with SEQUENCE. NEXTVAL in the select statement

I have a table emp

SQL > select * from emp;

EMPNO, ENAME

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

JOHN 5000

5001 ADAM

MIKE 5002

I need help to write a procedure to run ' select EMPNO | ENAME from emp' on a line at a time until the end of the table.

Try to use the below stated by "N as a sequence.nextval. It does not work. Please help me solve this.

Select EMPNO | ENAME from EMP

where rownum < N + 1

less

Select EMPNO | ENAME from EMP

where rownum < N;

So why not just make something like:

SQL > select "mysql - host = localhost - user = roor - password = rootpassword e ' create database ' |" " EmpNo | Ename | " » ;"
2 EMP;

"MYSQL - HOST = LOCALHOST - USER = ROOR - PASSWORD = ROOTPASSWORD-E" CREATEDATABASE'| "" EMPNO | ENAME | " » ;"

Then, you can copy and paste the results in a script file and run this script.

Don't know why you want to wait 15 seconds between each, as the mysql command is not likely to return control to the script until it has finished creating the database (at least that's what would make most of the commands, I use MySQL)

Function group with CLOB fields in the Select statement

I try to query our following sql database. Remove the Clob (a.description) field I managed. But I need the Clob (a.description) field. Here is my sql class

select  a.id_number, a.id_owner,  MAX (n.next_action_required)
            KEEP (DENSE_RANK LAST ORDER BY n.modified_date),
         MAX (n.modified_date) KEEP (DENSE_RANK LAST ORDER BY n.modified_date) 
from table1 a, table2 n
where a.id_number = n.id_number
group by a.id_number, a.id_owner

I tried the following which works sometimes, but not always because the Clob field length (a.description) varies; anywhere from 10 characters up to 12 000 characters. I get a few drafts with the following and some where the text is cut off. I can not write the correct dbms_lob.substr function.

select  a.id_number, a.id_owner,  MAX (n.next_action_required)
            KEEP (DENSE_RANK LAST ORDER BY n.modified_date),

Problem using sequence.nextval in java prepared statement
Hi guy,

Has anyone tried to put sequence.next in the prepared statement in java? I have a few questions to use.

example below

private static final String SQL_insertEQFCYPRICE = "INSERT INTO TABLE ()"
+ "col1, col2, col3.
+ "VALUES (seq1.nextval,?,?,?)"; "

Kind regards
John
'keycol' was something I composed for an example, because youre statement tried to insert 4 values but had only specified 3 columns...

If you have a table, and the sequence as follows:

Command > create table t1 (pk1 number, c2 char (10));
Command > create sequence s1;

and you run this statement:

Command > insert into t1 values (s1.nextval, 'abc');
1 row inserted.

You get the correct result:

Command > select * from t1;
< 1,="" abc="">
1 row found.

To do this in Java you would prepare the following statement:

insert into t1 values (s1.nextval?),

then, before each execution of the prepared statement you would use the 'set' method to set the desired parameter 2 input value. Works very well.

How to pass parameter in the function using the select statement?
Hello

I had a problem. I can't pass as parameter to the function by using the select statement. But it can pass as a parameter using the "code". How can I solve this problem?

For example,.
Select * from table (SplitFunction ('HS750020, HS750021')) < < < this work.

but

Select * from table (SplitFunction (select LOT_NO in the TRACER_SEARCH_SCHEDULE where JOB_ID = '36')) < < < do not work.

Thank you for trying to help him. Thank you.
Select * from table (SplitFunction (select LOT_NO in the TRACER_SEARCH_SCHEDULE where JOB_ID = '36'))< do="" not="">

Try like this
```
select * from table(select splitfunction(lot_no) from tracer_search_schedule where job_id='36')
```
Just make sure that your subquery returns only 1 row.

I tabele and a custom function, the custome service will update the column (amount) of the table based on the value of going through the function of the select statement.

SELECT id, stock, where an id = get_update (id);

Get_update function will return the same id I'm passing and update the column amount to a value in the
table a.

When I run the satament selection I have the updated data in the column amount in my first executtion, but if execute the same statement, again, I see the changes reflected. is it possible to get data updates to the first performance himself.

the function is of type PRAGMA AUTONOMOUS_TRANSACTION

function() nested in the select statement

Oracle 11g. Try to nest a function within the select statement. Goal: get the average customer rating for each of the qualified user.
Select user_name, f_get_avg_cust_rating() "Notation.
of u, OTHER_TABLES o TAB_USER
where u.id = o.id and another condition matched;
How Oracle would deal with the sql. Is it
(1) first of all display records based on the where clause, then call the f_get_avg_cust_rating() for each of the selected records OR
(2) for the analysis in tables, the f_get_avg_cust_rating() will be called for each record met?

I tried to use a statement select count nested inside the original SELECT statement but without success.

Jeff
You should be able to use a CASE statement for this in collaboration with the County. COUNTY does not indicate that null instances no I have not specified a part to the CASE ELSE (so the default value is NULL).
```
COUNT(CASE ST.GENDER WHEN 'F' THEN 1 END) as Female_count,
COUNT(CASE ST.GENDER WHEN 'M' THEN 1 END) as Male_count, 
```
Note that you need to remove the Gender of your query column.

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 '.

If COLUMN04 > 0 that the condition of "Z".

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".

validation for each 1,000 records to be inserted in the select statement
Hi, I have the following INSERTION in the SELECT statement.
The SELECT statement (who joined) data fo about 6 crores. I need to insert this data into another table.

Please suggest me the best way to do it.
I use the INSERT in the SELECT statement, but I want to use the statement commit for each 1,000 records.

How can I do this...
```
insert into emp_dept_master 
 select e.ename ,d.dname ,e.empno ,e.empno ,e.sal 
   from emp e , dept d
  where e.deptno = d.deptno       ------ how to use commit for every 1000 records .
```
Thank you
Method 4 is the best

You could combine method 3 and 1 (without dynamic SQL)

Method 2 is the less optimal solution from the list.

Using ROWNUM with SEQUENCE. NEXTVAL in the select statement
