How to update table1 field by using other table and function - oracle

I have two table and one function,
Table1 contains shop_code,batch_id,registry_id
shop_code| batch_id|registry_id
123 | 100 |12
124 | 100 |13
125 | 100 |12
Table2 contains shop_code,shop_name
shop_code| shop_name
123 | need to populate
124 | need to populate
125 | need to populate
Function1 take parameter registry_id from table1 and returns shop_name
Table2 shop_name is empty I want to populate against the shop_code.
I have tried my best but all effort is gone in vain.
It will be great if someone can help I am using Oracle.
I tried below code but giving error on from keyword
update TABLE2 set T2.SHOP_NAME = T.SHOP_NAME
from(
select GET_shop_name(t1.registry_id) as shop_name ,
t1.shop_code shop_code
from TABLE1 T1
) t where t.shop_code = t1.shop_code;

I am not entirely 100% sure if I got your question right, but I believe you want something like
update
table2 u
set
shop_name = (
select
get_shop_name(t1.batch_id)
from
table1 t1
where
t1.chop_code = u.shop_code
);

can you try this approach try to put inner query to get shop name value; I have not tested it but I think approach will work for you.
update TABLE2 T2
set T2.SHOP_NAME =
(select GET_shop_name(t1.batch_id, t1.shop_code) from table1 t1 wehre t1.shop_code = t2.shop_code)
where T2.shop_name is null

You want the MERGE statement.
Something like this might work:
MERGE INTO TABLE2 t2
USING (
SELECT GET_shop_name(t1.batch_id) AS shop_name ,
t1.shop_code shop_code
FROM TABLE1 T1 ) t1
ON (t2.shop_code = t1.shop_code)
WHEN MATCHED THEN
UPDATE SET t2.shop_name = t1.shop_name
;
You'll have to excuse if the exact code above doesn't work I don't have SQL Dev where I am right now for syntax details. :)

Update oracle query issue with Join

I dont understand why its giving Sql Command not properly ended,
Update Table1
Set LS.SECU_CHECKER_CODE = '1000',
LS.SECU_CHECKER_DATE = To_Char(SysDate, 'YYYYMMDDHH24MISS'),
LS.SECU_RECORD_STATUS = 98
From Table1 LS
Join Table2 LS2
On LS2.SECC_SECURITY_ID = LS.SECU_SECURITY_ID
Where LS2.SECC_LIMIT_ID = '00010101010101';
The syntax for updating from a view is different in Oracle from the syntax you are using. However, you shouldn't even update from a view in your case, because you are not using the other table's content, but merely check for existence of a record for which you should rather use EXISTS or IN:
update table1
set secu_checker_code = '1000'
, secu_checker_date = to_char(sysdate, 'yyyymmddhh24miss')
, secu_record_status = 98
where secu_security_id in
(
select secc_security_id
from table2
where secc_limit_id = '00010101010101'
);
It looks like you are trying to update a selection of table 1. You need a where clause.
Possibly something like this:
update table1 t1
set ls.secu_checker_code = '1000'
,ls.secu_checker_date = to_char(sysdate, 'YYYYMMDDHH24MISS')
,ls.secu_record_status = 98
where t1.secu_security_id in (select t2.secc_security_id
from table2 t2
where t2.secc_limit_id = '00010101010101');
This is also working fine
UPDATE table1
SET (SECU_CHECKER_CODE,
SECU_CHECKER_DATE,
SECU_RECORD_STATUS) = (
Select '1000',
To_Date(SysDate),
98
From table1
Join table2
On SECC_SECURITY_ID = SECU_SECURITY_ID
Where SECC_LIMIT_ID = '00010101010101')

How to update and set values based on multiple joins in select statment?

I want to update a column prtnum and revlvl in table invdtl based on value from select statment, here is the code
update invdtl set invdtl.prtnum = usr_prtmst_xref.prtnum,invdtl.revlvl =
usr_prtmst_xref.colnam ([select
invdtl.prtnum,usr_prtmst_xref.prtnum AS
crossref,invdtl.revlvl,aremst.arecod,aremst.fwiflg from invdtl
join usr_prtmst_xref
on usr_prtmst_xref.prtnum = usr_prtmst_xref.prtnum
join invsub
join invlod
join locmst
join aremst
on aremst.arecod = locmst.arecod
and aremst.wh_id = locmst.wh_id
on locmst.stoloc = invlod.stoloc
and locmst.wh_id = invlod.wh_id
on invlod.lodnum = invsub.lodnum
on invsub.subnum = invdtl.subnum where aremst.arecod = 'EXPR' or
aremst.fwiflg = '1' and rownum <2])
I want to copy two values prtnum and revlvl that are returned by select statement but there is some syntax issue.
There are a bunch of errors here:
The syntax for a multi-column update is basically
update blah
set ( col1, col2 ) = ( select x, y
from
...
)
The syntax for multiple joins is basically
from table1 t1
join table2 t2
on t1.col = t2.col
join table3 t2 on
t2.col = ...
Get ride of "[" and "]"
The predicate rownum<2 is probably to get around the message you received, something like "single row sub-query returns more than 1
row" Which this predicate "fixes" that problem, you are just getting
the first random row; probably not what you want. You probably need to
correlate the sub-query with the update
I would fix these basic syntax errors and try again.

update set value based on another value of another column and/or same column in another row:-ORA 1427

I'm trying to set a column to reset to zero or increment by +1 based on a pass or fail in another column, and/or the value of that same column in the previous weeks row.
There are two other variable columns which must match those in the previous weeks row.
Table is something like:
WEEK | ID1 | ID2 | FLAG | INCREMENT_COUNT |
--------------------------------------------------------
--------------------------------------------------------
I have been trying to get this part of the procedure to work, and the best I've got so far is:
ID_IN and ID_IN3 are passed in the procedure call
OLD_DATE and NEW_DATE are set as the previous week and current week
----------------------------------------------------------------------
update table1
set table1.INCREMENT_COUNT = CASE
WHEN table1.FLAG is null then null
WHEN table1.FLAG = 1 then 0
WHEN table1.FLAG = 0 then (NVL(INCREMENT_COUNT,0)+ 1)
END
where (select INCREMENT_COUNT
from table1
where WEEK=NEW_DATE
and ID1=ID_IN
and exists (select (1)
from table2
where table1.ID2=table2.ID2
and table2.ID3=ID_IN3))
=
(select INCREMENT_COUNT
from table1
where WEEK=OLD_DATE
and ID1=ID_IN
and exists (select (1)
from table2
where table1.ID2=table2.ID2
and table2.ID3=ID_IN3));
When this procedure is called I get the error
ORA-01427: single-row subquery returns more than one row
Additionally, in MySQL I could do it something like this and get it working...
update table1 as t01
left join(select ID3, ID2, INCREMENT_COUNT as prev_count from table1 as t10 inner join table2 as t2 on t10.ID2=t2.ID2 where ID1=ID_IN and ID3=ID_IN3 and t10.WEEK=OLD_DATE) as prev_date on t01.WEEK=NEW_DATE and prev_date.ID2=t01.ID2 and t01.ID1=ID_IN
set t01.INCREMENT_COUNT = if(t1.FLAG is null, null, if(t1.FLAG,0, IFNULL(prev_date.prev_count,0)+1))
where t01.ID1=ID_IN
and t1.WEEK=NEW_DATE
and prev_date.ID3=ID_IN3;
Similarl to your mySQL example, you can do something like this in oracle. This may not work for you depending on your data model. I've put together a crude basic version based on your information, but you've not provided enough information about your data model and your tables/aliases/column names are poor for readability...
(more on update with a subquery here -> https://docs.oracle.com/database/121/SQLRF/statements_10008.htm#i2067871)
update
(select t01.increment_count, t01.flag, prev_date.prev_count
from table1 t01
left join(select ID3, ID2, INCREMENT_COUNT as prev_count
from table1 t10
inner join table2 t2 on t10.ID2=t2.ID2
where ID1=ID_IN
and ID3=ID_IN3
and t10.WEEK=OLD_DATE) prev_date on t01.WEEK=NEW_DATE and prev_date.ID2=t01.ID2 and t01.ID1=ID_IN
where t01.ID1=ID_IN
and t1.WEEK=NEW_DATE
and prev_date.ID3=ID_IN3)
set INCREMENT_COUNT = if(FLAG is null, null, if(FLAG,0, IFNULL(prev_count,0)+1));
One of the queries in where condition returns more than 1 record
This seems to have done the job.
Thanks for the help, it got me thinking in a different way.
UPDATE TABLE1 T01
SET INCREMENT_COUNT = CASE
WHEN T01.FLAG IS NULL THEN NULL
WHEN T01.FLAG = 1 THEN 0
WHEN T01.FLAG = 0 THEN (NVL((SELECT INCREMENT_COUNT
FROM TABLE1 T10
WHERE T10.WEEK=OLD_DATE
AND T01.WEEK=NEW_DATE
AND T01.ID2=T10.ID2
AND ID1=ID_IN),0)+ 1)
END
WHERE EXISTS (SELECT (1)
FROM TABLE2
WHERE TABLE1.ID2=TABLE2.ID2
AND TABLE2.ID3=ID_IN3);

Oracle Join Two Queries With Distinct Answer

I need help in linking two tables together to bring back data as I need.
I have two queries:
The first is as follows:
SELECT
POI.PO_ID as PO_ID, SUM(POI.INV_QTY) AS INV_QTY, POI.INV_NUMBER,
PO.SUP_SUP_ID AS SUPPLIER
FROM TABLE1 POI, PUR_ORDS PO
WHERE POI.PO_ID = '56886' AND POI.PO_ID = PO.PO_ID
GROUP BY POI.PO_ID, POI.INV_NUMBER, PO.SUP_SUP_ID
ORDER BY POI.INV_NUMBER ASC
The Results of this query are as follows:
PO_ID|INV_QTY|INV_NUMBER|SUPPLIER
---------------------------------
56886| 105|INV1 |SUP1
56886| 106|INV2 |SUP1
The second query I have is this:
SELECT
DIL.PO_PO_ID, sum(DIL.ACPTD_QTY) as ACPTD_QTY,
DIL.DLVD_DLVY_NUMB AS DEL_NUM
FROM TABLE2 DIL
where DIL.PO_PO_ID = '56886'
GROUP BY PO_PO_ID, DIL.DLVD_DLVY_NUMB
order by del_num
The Results of this query are as follows:
PO_PO_ID|ACPTD_QTY|DEL_NUM
--------------------------
56886| 105| 1
56886| 106| 2
Now I am attempting to join the two tables, but I get multiple values appearing, using the following:
SELECT DISTINCT(PO_ID), INV_NUMBER, INV_QTY, SUPPLIER, ACPTD_QTY, DEL_NUM
FROM
(SELECT
SELECT POI.PO_ID as PO_ID, SUM(POI.INV_QTY) AS INV_QTY,
POI.INV_NUMBER, PO.SUP_SUP_ID AS SUPPLIER
FROM TABLE1 POI, PUR_ORDS PO
WHERE POI.PO_ID = '56886'
AND POI.PO_ID = PO.PO_ID
GROUP BY POI.PO_ID, POI.INV_NUMBER, PO.SUP_SUP_ID
ORDER BY POI.INV_NUMBER ASC) POINET
INNER JOIN
(SELECT DIL.PO_PO_ID, sum(DIL.ACPTD_QTY) as ACPTD_QTY,
DIL.DLVD_DLVY_NUMB AS DEL_NUM
FROM TABLE 2 DIL
where DIL.PO_PO_ID = '56886'
GROUP BY PO_PO_ID, DIL.DLVD_DLVY_NUMB
order by DEL_NUM) DILV
ON DILV.PO_PO_ID = POINET.PO_ID
GROUP BY PO_ID, INV_NUMBER, INV_QTY, SUPPLIER, ACPTD_QTY, DEL_NUM
ORDER BY INV_NUMBER
However the dataset I get is this:
PO_ID|INV_NUMBER |INV_QTY|SUPPLIER|ACPTD_QTY|DEL_NUM
-----------------------------------------------------
56886|K-101/2014-15| 105|SUP1 | 105| 1
56886|K-101/2014-15| 105|SUP1 | 106| 2
56886|K-107/2014-15| 106|SUP1 | 105| 1
56886|K-107/2014-15| 106|SUP1 | 106| 2
However I need it show the following:
PO_ID|INV_NUMBER |INV_QTY|SUPPLIER|ACPTD_QTY|DEL_NUM
------------------------------------------------------
56886|K-101/2014-15| 105|SUP1 | 105| 1
56886|K-107/2014-15| 106|SUP1 | 106| 2
What do I need to do, to tweak my query?
Any help would be much appreciated.
I think you just need to modify your join statement to join on both columns
ON DILV.PO_PO_ID = POINET.PO_ID
AND DILV.INV_QTY = POINET.ACPTD_QTY
Actually, you can probably leave out the PO_ID, because I it's the same in both subqueries:
i.e. Just do this (on the third last line):
ON DILV.INV_QTY = POINET.ACPTD_QTY

Copy records from one table to another with pl-sql

I want to copy records from one table to another.
The only records from table 1 that will be copied to table 2 are the ones that still dont exist in table 2.
If duplicate records exists in Table 1 then only be copied to table 2 the record with the larger size name.
I could already implement a query that almost does what I want.
The problem I have is when there are names with the same maximum size of characters.
In these cases, my query returns more than one record and I just want to insert one new record in table 2.
Does anyone know how I can fix this?
Here is my code:
For x in (Select distinct xdd.id_t, xdd.name_t
From table1 xdd
Where xdd.id_t not in (Select distinct det.id_t2
From table2 det)
And LENGTH(xdd.name_t) in (Select Max(LENGTH(xdd2.name_t))
From table1 xdd2
Where xdd2.id_t = xdd.id_t)
) Loop
Insert into id_t2 (id_t2, name_t2)
Values (x.id_t, x.name_t);
End loop;
Can you give me an example to solve this?
Sure. If I understood requirements correctly, then the merge statement will look similar to this one:
We use row_number() analytic function to choose a duplicate record with longer name_t
merge into table_two t2
using(
select id_t
, name_t
from (select id_t
, name_t
, row_number() over(partition by id_t
order by length(name_t) desc) as rn
from table_one) q
where q.rn = 1
) t1
on (t2.id_t = t1.id_t)
when not matched then
insert(id_t, name_t)
values(t1.id_t, t1.name_t)
SQLFiddle demo
This is a merge statement that should "upsert" data from table 1 into table 2. Matching keys should update only when the name field in table1 is greater than that of table 2. And inserts should occur when keys from table one are not matched to table 2.
MERGE INTO table2 D
USING (SELECT table1.id_t, table1.name_t FROM table1) S
ON (D.id_t2 = S.id_t)
WHEN MATCHED THEN UPDATE SET D.name_t2 = S.name_t
WHERE (LENGTH(S.name_t) > LENGTH(D.name_t2))
WHEN NOT MATCHED THEN INSERT (D.id_t, D.name_t)
VALUES (S.id_t2, S.name_t2);
