Following query works but i want with 2 fields
CREATE TABLE TOTAPPS (ANUM) AS SELECT a.A# FROM APPLICANT a.
This is work that
//TOTAPPS
ANUM
--------
if i want to create with 2 fields?
//Totapps
ANUM NUMBER
---------------------------
how should i create the table? in order to get the correct out?
and the NUMBER is refer to the ANUM , for example
CREATE TABLE TOTAPPS (ANUM) AS SELECT a.A# FROM APPLICANT a,
(NUMBER) AS SELECT COUNT(*) FROM a.A#;
but it's failed to work.
Calling a column NUMBER is not correct as it is a reserved word. Assuming from your second query that you want to add to your table distinct values of a.A# and the count of these values in the table, you should try this:
CREATE TABLE TOTAPPS (ANUM, MYNUMBER) AS
SELECT a.A#, COUNT(a.A#) FROM APPLICANT a GROUP BY a.A#;

I'm trying to create a table from multiple tables.
table a has list of IDs and I need count of IDs stored in table C.
Table b has list of IDs and need the count of them as well in table C.
I'm trying below but getting an error:
Create or replace tablec as
select
Count(id) as total
from table a,
select count(ref) as ref_total
from table b
My desired output should look like below and should be filter applied by date.
Consider using a subquery for each count like below.
CREATE OR REPLACE TABLE TableC AS
SELECT (SELECT COUNT(id) FROM TableA) AS total,
(SELECT COUNT(ref) FROM TableB) AS ref_total
;
output:
But date range is something optional. For date range, I'm thinking to get whole data in new table then I can run select on table C
I think you can add date filter in WHERE clause of each subquery for your purpose.
I have the tables below:
tb_profile tb_mbx tb_profile_mbx tb_profile_cd
id id id_profile id_perfil
cod_mat mbx id_mbx id_cd (matches id_mbx)
concil bp
masc
I need to create a query that when validating that the id_cd 1,2,4,5
and 6 exists in tb_profile_cd, perform an insert in the
tb_profile_mbx table with the cod_matrix parameters of the tb_profile
table.
Remembering that each concil has its ID in the tb_mbx table and a
concil has many cod_mat.
Another point is that the concil id_mbx represents the id_cd of the
tb_profile_cd table.
One more point is that as I said above, that a concil has many
cod_mat. I have around 20 thousand records for each concil.
For my need, try to consult the query below, but Oracle returned an error:
insert into tb_profile_mbx values (seq_profile_mbx.nextval,
(select id from tb_profile where concil like '%NEXXERA%')
,(select id from tb_mbx where mbx like '%NEXXERA%')
,null
,null);
ORA-01427: single line subquery returns more than one line
Would there be another way to do this query?
Thanks in advance!
You can insert all matching combinations of matches using:
insert into tb_profile_mbx (id_profile, id_mbx)
select p.id, m.id
from tb_profile p join
tb_mbx m
on p.concil like '%NEXXERA%' and m.mbx like '%NEXXERA%';
I would recommend running the select to see if it returns the values you want.
You only show two columns for tb_profile_mbx, so I've only included two columns in the insert.
I am trying to create a trigger that when a row is deleted from a table it gets inserted in another table:
1 Create Or Replace Trigger cancel
2 After Delete
3 On OrderTable
4 For EACH ROW
5 Begin
6 Insert Into CancelledOrders Values (:old.acctNum, age, phone)
7 From OrderTable Natural Join Customer
8 Where acctid = :old.acctNum AND menuid = :old.menuNum;
9 End;
10 /
11 Show Errors;
I want to grab the acctNum, age, and phone. The acctNum is from the Order table but the age and phone is from the Customer table. Therefore I join the two tables (on the acctid key). So the joined result will look like this:
acctNum Age Phone
I get this error when I try to compile the Trigger:
2/2 PL/SQL: SQL Statement ignored
3/2 PL/SQL: ORA-00933: SQL command not properly ended
Does anyone know the problem?
EDIT:
Table Structure:
OrderTable: AcctNum MenuNum startOrder endOrder
Customer Table: AcctNum age phone
You're mixing the values and select (subquery) syntax, which are for different things. You can insert from a query that uses a value from the :old pseudorecord and values from the customer table:
Insert Into CancelledOrders -- (acctNum, age, phone)
Select :old.acctNum, age, phone
From Customer
Where acctNum = :old.acctNum;
It's better to specify the columns in the target table as part of the insert clause (I've left that commented out in case the names are different). You also don't want (or need) to requery the table the trigger is against; you already have the data you need, and it will get a mutating-table error in some circumstances. So no join is needed.
Your insert statement is incorrect. You need to specify the columns you want to select in the tables.
Add the select clause to your insert statement. Also, removed the values keyword and specify column names:
Insert Into CancelledOrders (acctNum, age, phone)
Select :old.acctNum, age, phone
From OrderTable Natural Join Customer
Where acctid = :old.acctNum AND menuid = :old.menuNum;
I'm using two Stored Procedures and two Table in My Sql Server.
First Table Structure.
Second Table Structure.
When a Customer books a Order then the Data will be Inserted in Table 1.
I'm using a Select Query in another Page Which Selects the Details from the Second Table.
If a row with a billno from first table is not Present in Second Table I want to Insert into the Second Table with some Default Values in the Select Query. How can I do this
??
If you want to insert in the same query, you will have to create a stored procedure. There you'll query if row exists in second table, and, if not, insert a new entity in second table.
Your code should look something like this:
-- --------------------------------------------------------------------------------
-- Routine DDL
-- Note: comments before and after the routine body will not be stored by the server
-- --------------------------------------------------------------------------------
DELIMITER $$
CREATE DEFINER=`table`#`%` PROCEDURE `insertBill`(IN billNo int, val1 int, val2 int, val3 int)
BEGIN
DECLARE totalres INT DEFAULT 0;
select count(*) from SECOND_TABLE where Bill_Number = billNo INTO totalres;
IF totalres < 1 THEN
INSERT into SECOND_TABLE values(val1,val2,val3);
END IF;
END
Val1,val2 and val3 are the valuest to be inserted into second table.
Hope this helps.
What you do is to LEFT JOIN the two tables and then select only the ones where the second table had no row to join, meaning the bill number were missing.
In the example below, you can replace #default_inform_status and #default_response_status with your default values.
INSERT INTO second_table (Bill_Number, Rest_Inform_Status, Rest_Response_Status)
SELECT ft.Bill_Number, #default_inform_status, #default_response_status
FROM first_table ft
LEFT JOIN second_table st
ON st.Bill_Number = ft.Bill_number
WHERE st.Bill_Number IS NULL
If it is possible to have duplicates of the same Bill_Number in the first table, you should also add a DISTINCT after the SELECT. But considering the fact that it is a primary key, this is no issue for you.
i have 2 tables.
TABLE A COLUMNS - aid , aname
TABLE B COLUMNS - bid , bname
from table A, i will pick up data from column 'aid',
AND insert it in 'bid' column of table B , but in bname column of table B, i will insert a new value. how do i do this?
create table A(aid int,aname char)
insert into A values(111, 'e')
create table B(bid int, bname char)
insert into B (bid,bname)
bid will take value from the query : select aid from a
bname will get a new value -m
expected result should be : THE TABLE B WILL HAVE :
bid bname
--- -----
111 m
Try this:
insert into b (bid, bname) select aid, 'm' as bname_fixed_val from a
Two facts enabled the solution above:
The insert .. select clause allows you to insert the values returned with any select.
You can return constant values as fields with select, like for instance:
SELECT 0 as id, 'John' as name
Combining these two points together, I used an insert..select clause to select the field value from the first table (aid), along with a constant value for the second field (m). The AS bname_fixed_val clause is simply a field alias, and can be omitted.
