Proper insert using a sub select
I have always used:
insert into table_x (field_1, field_2)
select 'data_for_field_1', data_for_field_2 from
table_y;
This works no matter what.
I have identified the following insert that works in 8i but not 8.0.5:
insert into table_x (field_1, field_2)
values ('data_for_field_1', (select data_for_field_2 from
table_y));
Can someone please tell me why this insert is a no no. I would greatly appreciate any logic on how the db engine processes this kind of statement, why it works in 8i but not lesser versions, or simply an argument why not to do this.
Thanks a bunch.
Why it works in 8.1 but not in lesser versions? Becaue Oracle enhances SQL in each version.

Delete statement that uses a sub-select with the statement in the cursor
Hi all,
How to write write a delete statement that uses a sub-select with the statement in the cursor?

In such case I think is better to create a view an perform the delete using it. Example (using HR schema):

If you are haivng a problem understanding the answers, do not start a new thread, otherwise the same people who were helping you originally may not know you are still having a problem.
To insert multiple rows of data you cannot use the VALUES clause of the INSERT statement (as it tells you in the documentation if you read it).
You need:
INSERT INTO ...
SELECT ... FROM ... UNION ALL
SELECT ... FROM ... UNION ALL
SELECT ... FROM ... etc.or, in your case you would need something more simply like
insert into FISH_FAMILIES(SCIENCE_NAME,ARABIC_NAME,LATIN_NAME,IS_FAMILY)

Insert Using SELECT & Sub-SELECT
Hi All,
I am trying to insert records into a table using SELECT statement. The SELECT statement has a Sub-SELECT statement as follows:
INSERT INTO table1(c1,c2,c3,c4,c5)
SELECT c1,c2, (SELECT MAX(C3)+a1.c3
FROM table1
WHERE c1 = var1
AND c2 = a1.c2
GROUP BY c3),c4,c5,
FROM table1 a1
WHERE c1 = var1
The above works fine when run from SQL*PLUS but gives compilation error when included in PL/SQL pacakge.
I am using Oracle 8.1.7.
Could you any one please tell me if I have missed something?
Thanks,
Satyen.In 8i, you will need to use dynamic SQL to execute this statement because the PL/SQL parser does not understand all SQL syntax (including SELECT in a column list).
execute immediate

' SELECT c1, c2, (SELECT MAX(C3)+a1.c3 FROM table1 WHERE c1 = :var1 AND c2 = a1.c2 GROUP BY c3), c4, c5' ||

Sub-SELECT in Bulk INSERT- Performance Clarification
I have 2 tables- emp_new & emp_old. I need to load all data from emp_old to emp_new. There is a transaction_id column in emp_new whose value needs to be fetched from a main_transaction table which also includes a Region Code column. Something like -
TRANSACTION_ID REGION_CODE
100 US
101 AMER
102 APAC
My bulk insert query looks like this -
INSERT INTO emp_new
(col1,
col2,
transaction_id)
SELECT
col1,
col2,
*(select transaction_id from main_transaction where region_code = 'US')*
FROM emp_old
There would be millions of rows which need to be loaded in this way. I would like to know if the sub-SELECT to fetch the transaction_id would be re-executed for every row, which would be very costly and I'm actually looking for a way to avoid this. The main_transcation table is a pre-loaded table and its values are not going to change. Is there a way (via some HINT) to indicate that the sub-SELECT should not get re-executed for every row ?
On a different note, the execution plan of the above bulk INSERT looks like -
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)|
| 0 | INSERT STATEMENT | | 11M| 54M| 6124 (4)|
| 1 | INDEX FAST FULL SCAN| EMPO_IE2_IDX | 11M| 54M| 6124 (4)|
EMPO_IE2_IDX -> Index on emp_old
I'm surprised to see that the table main_transaction does not feature in the execution plan at all. Does this mean that the sub-SELECT will not get re-executed for every row? However, atleast for the first read, I would assume that the table should appear in the plan.
Can someone help me in understanding this ?Dear

Number of rows inserted is different in bulk insert using select statement
I am facing a problem in bulk insert using SELECT statement.
My sql statement is like below.
strQuery :='INSERT INTO TAB3
(SELECT t1.c1,t2.c2
FROM TAB1 t1, TAB2 t2
WHERE t1.c1 = t2.c1
AND t1.c3 between 10 and 15 AND)' ....... some other conditions.
EXECUTE IMMEDIATE strQuery ;
These SQL statements are inside a procedure. And this procedure is called from C#.
The number of rows returned by the "SELECT" query is 70.
On the very first time call of this procedure, the number rows inserted using strQuery is *70*.
But in the next time call (in the same transaction) of the procedure, the number rows inserted is only *50*.
And further if we are repeating calling this procedure, it will insert sometimes 70 or 50 etc. It is showing some inconsistency.
On my initial analysis it is found that, the default optimizer is "ALL_ROWS". When i changed the optimizer mode to "rule", this issue is not coming.
Anybody faced these kind of issues?
Can anyone tell what would be the reason of this issue..? any other work around for this...?
I am using Oracle 10g R2 version.

Edited by: user13339527 on Jun 29, 2010 3:56 AMYou have very likely concurrent transactions on the database:
>
By default, Oracle Database permits concurrently running transactions to modify, add, or delete rows in the same table, and in the same data block. Changes made by one transaction are not seen by another concurrent transaction until the transaction that made the changes commits.

If you want to make sure that the same query always retrieves the same rows in a given transaction you need to use transaction isolation level serializable instead of read committed which is the default in Oracle.
Please read http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10471/adfns_sqlproc.htm#ADFNS00204.

Stuck again, it seems as though I am not the sharpest tool in the box when it comes to XML. Boss seems to love XML though....
In SQL I have the ability to do something similar to the following :
SELECT * FROM JOBS
WHERE JOB_ID IN(SELECT JOB_ID WHERE ACTIVE = 1)
In this scenario no real need to do a sub select however it demonstrates my point.
Is it possible to achive this using an XML document in my sub select?
eg something like
SELECT * FROM JOBS WHERE JOB_ID IN(EXTRACTVALUE(var,xpath JOB_ID)
If I had a big list would this iterate through each instance of the value I want to join on???Have a look at the XML DB technical whitepaper

Can I do an Insert using two selects from different tables?
Hi,
I have three tables, Course (CID, NAME, TIME)
Teacher (TID, NAME, DESCRIPTION) and OfferedBy(CID, TID) to match a course to a teacher.
After I do an insert on Course, I want to be able to do an insert on OfferedBy using the CID of the course I inserted, and the TID of the teacher that's offering it.
I tried this after doing inserts on Course and Teacher:
INSERT INTO OfferedBy values (SELECT CID FROM Course where courseName = 'name' , SELECT TID FROM Teacher WHERE LastName = 'teacherName').
I get an ORA 00907 error.
What am I doing wrong? Can this actually be done?
Thank you
IHi,
How would you relate the TID with CID?
I tried this after doing inserts on Course and Teacher:
INSERT INTO OfferedBy values (SELECT CID FROM Course where courseName >= 'name' , SELECT TID FROM Teacher WHERE LastName = 'teacherName').
I get an ORA 00907 error.You can use the query in this way:
SQL> SELECT ( ( SELECT dummy FROM DUAL), (SELECT DUMMY FROM DUAL)) FROM DUAL;
SELECT ( ( SELECT dummy FROM DUAL), (SELECT DUMMY FROM DUAL)) FROM DUAL

AND pha.vendor_id = 98
AND pha.type_lookup_code = 'CONTRACT'
AND pha.org_id IN(7041, 7042);The above query runs quicky (approx. 1 second). If I take out the AND pha.vendor_id = 98 then the query takes a few minutes to run.
When I try to export it, or scroll down to view > 500 rows, TOAD crashes.
I know this isn't a TOAD forum, but I think that this is probably an issue with my no doubt rubbish SQL.
If I take out this sub-select, then the problem doesn't happen:
, (SELECT COUNT(DISTINCT pha2.po_header_id)
FROM po.po_headers_all pha2
, po.po_lines_all pla
WHERE pha2.po_header_id = pla.po_header_id
AND pla.contract_id = pha.po_header_id) po_countHowever, I can't work out a better way of getting the data I need.
The sub-select counts POs which have been raised where the contractID on the PO line is the same as the PO Header ID from the main query.
Any advice please, on what I could do to sort this out would be much appreciated.
Thanks!Hi,
It looks like you can replace both scalar sub-queries with a join, like this:
WITH header_lines_summary AS
SELECT pla.contract_id
, COUNT (DISTINCT pha2.po_header_id) AS po_count
, MAX (pha2.creation_date) AS latest_cpa_po
FROM po.po_headers_all pha2
, po.po_lines_all pla
WHERE pha2.po_header_id = pla.po_header_id
GROUP BY pla.contract_id
) -- Everything up to this line is new
SELECT pha.segment1
, pha.type_lookup_code
, hls.po_count -- Changed
, hls.latest_cpa_po -- Changed
FROM po.po_headers_all pha
, po.po_vendors pv
, po.po_vendor_sites_all pvsa
, header_lines_summary hls -- New
WHERE pha.vendor_id = pv.vendor_id
AND pha.vendor_site_id = pvsa.vendor_site_id
AND pha.po_header_id = hls.contract_id (+) -- New
-- AND pv.VENDOR_NAME LIKE 'H%'
AND pha.vendor_id = 98
AND pha.type_lookup_code = 'CONTRACT'
AND pha.org_id IN (7041, 7042);Aside from the sub-query (which is entirely new), the query above is just what you posted, with 2 lines changed and 2 lines added, as marked.
This should be more efficient, but I don't know for certain that it will solve the Toad problem.

Please note that I have used
SQL CTE expressions a lot in the SQL query to prevent usage of sub-select and temp tables.
There is also a

T-SQL - PL/SQL conversion: insert into ... select problem
Hi!
If I have an insert into ... select statement in T-SQL without a 'from' clause:
bq. insert into sometable (foo, bar) \\ select 5, case when @bar=5 then 4 else 3 end
its translation is:
bq. INSERT INTO sometable \\ ( foo, bar ) \\ VALUES ( 5, CASE \\ WHEN 5 = 5 THEN 4 \\ ELSE 3 \\ END col );
and I got: ORA-00917: "missing comma" for that. I'm not sure if it's a bug in the migration code, or is there a trick so that I can use 'CASE' in an insert into .. values statement somehow?
ZoliYou have to remove the column name. I just simplified your test case to check and it's working:
CREATE TABLE test(
id NUMBER
INSERT
INTO test(id)
VALUES(CASE WHEN 5=5 THEN 4 ELSE 3 END)
SELECT *
FROM test

Using procedure in SELECT statement
I have a select statement that currently uses 4 functions to receive necessary values. All the functions are recursive and returns values from the same row.
What I would like to do is replace these for function calls with 1 procedure. Does anybody know if it possible to use a procedure in this way inside a select statement?
If so, do you have the syntax for doing this?
E.g
SELECT
Mdbrd_Pkg.calculate_fixed_charge_fn(in_rc_id, ap.CONFIGSET_ID) AS FIXED_CHARGE,
Mdbrd_Pkg.calculate_charge_rate_fn(in_rc_id, ap.CONFIGSET_ID) AS CHARGE_RATE,
Mdbrd_Pkg.tax_liable_fn(in_rc_id, ap.CONFIGSET_ID) AS TAX_LIABLE,
Mdbrd_Pkg.charge_unit_fn( in_rc_id, ap.CONFIGSET_ID) AS CHARGEUNIT_ID
FROM .....This cannot be done. The part of the function used in the SELECT statement is the return value: procedures don't have return values (that's what makes tham procedures and not functions).
Obviously I don't know what your code does, but you should consider putting them into a single function that returns a TYPE with four attributes and then using the TABLE() function to cast them into something you could reference in the FROM clause of a correlated sub-query. Sounds a bit messy though.
Do these functions actually select data? Where does the recursion fit in?
