Database: Oracle
I want to insert data from table 1 to table 2 but the catch is, primary key of table 2 is the combination of first 4 letters and last 4 numbers of the primary key of table 1.
For example:
Table 1 - primary key : abcd12349887/abcd22339887/abcder019987
In this case even if the primary key of table 1 is different, but when I extract the 1st 4 and last 4 chars, the output will be same abcd9887
So, when I use select to insert data, I get error of duplicate PK in table 2.
What I want is if the data of the PK is already present then don't add that record.
Here's my complete stored procedure:
INSERT INTO CPIPRODUCTFAMILIE
(productfamilieid, rapport, mesh, mesh_uitbreiding, productlabelid)
(SELECT DISTINCT (CONCAT(SUBSTR(p.productnummer,1,4),SUBSTR(p.productnummer,8,4)))
productnummer,
ps.rapport, ps.mesh, ps.mesh_uitbreiding, ps.productlabelid
FROM productspecificatie ps, productgroep pg,
product p left join cpiproductfamilie cpf
on (CONCAT(SUBSTR(p.productnummer,1,4),SUBSTR(p.productnummer,8,4))) = cpf.productfamilieid
WHERE p.productnummer = ps.productnummer
AND p.productgroepid = pg.productgroepid
AND cpf.productfamilieid IS NULL
AND pg.productietype = 'P'
**AND p.ROWID IN (SELECT MAX(ROWID) FROM product
GROUP BY (CONCAT(SUBSTR(productnummer,1,4),SUBSTR(productnummer,8,4))))**
AND (CONCAT(SUBSTR(p.productnummer,1,2),SUBSTR(p.productnummer,8,4))) not in
(select productfamilieid from cpiproductfamilie));
The highlighted section seems to be wrong, and because of this the data is not picking up.
Please help
Try using this.
p.productnummer IN (SELECT MAX(productnummer) FROM product
GROUP BY (CONCAT(SUBSTR(productnummer,1,4),SUBSTR(productnummer,8,4))))

I have a table that I am trying to insert multiple records into using a select statement.
The ID field is an INT and not autoincremented but I do need to increment in in the INSERT.
The table belongs to a third party product we use for our ERP so I cannot change the property of the ID.
The insert is supposed to create a record in the EXT01100 table for each line item on a particular sales order.
Here is the code I am using:
INSERT INTO EXT01100 (Extender_Record_ID, Extender_Window_ID, Extender_Key_Values_1 , Extender_Key_Values_2, Extender_Key_Values_3)
SELECT (SELECT MAX(EXTENDER_RECORD_ID) + 1 FROM EXT01100), 'ECO_FEE_DIGIT', SOL.LNITMSEQ, SOL.SOPNUMBE, SOL.SOPTYPE
FROM SOP10200 SOL WITH(NOLOCK)
WHERE SOL.SOPTYPE = #InTYPE AND SOL.SOPNUMBE = #INNUMBE AND SOL.LNITMSEQ <> 0
This works on a single line order, but multiple line orders will produce a Primary Key duplicate error so I don't think I can use (SELECT MAX(EXTENDER_RECORD_ID) + 1 FROM EXT01100) in this case.
This is in SQL server.
Any help is greatly appreciated!
You can use row_number to ensure each row has a unique ID, and you need to take an exclusive lock on your main sequence table, and you need to remove your nolock.
INSERT INTO EXT01100 (Extender_Record_ID, Extender_Window_ID, Extender_Key_Values_1 , Extender_Key_Values_2, Extender_Key_Values_3)
SELECT (SELECT MAX(EXTENDER_RECORD_ID) FROM EXT01100 WITH (TABLOCKX)) + ROW_NUMBER() OVER (ORDER BY SOL.LNITMSEQ)
, 'ECO_FEE_DIGIT', SOL.LNITMSEQ, SOL.SOPNUMBE, SOL.SOPTYPE
FROM SOP10200 SOL
WHERE SOL.SOPTYPE = #InTYPE AND SOL.SOPNUMBE = #INNUMBE AND SOL.LNITMSEQ <> 0;
Seconding a recommendation from the comments above, we use Sequences in our production system with no problem. Here's how it looks:
create sequence SQ_Extender_Record_ID
minvalue 1
start with 1
cache 100;
INSERT INTO EXT01100 (Extender_Record_ID, Extender_Window_ID, Extender_Key_Values_1 , Extender_Key_Values_2, Extender_Key_Values_3)
SELECT (next value for SQ_Extender_Record_ID), 'ECO_FEE_DIGIT', SOL.LNITMSEQ, SOL.SOPNUMBE, SOL.SOPTYPE
FROM SOP10200 SOL
WHERE SOL.SOPTYPE = #InTYPE AND SOL.SOPNUMBE = #INNUMBE AND SOL.LNITMSEQ <> 0
Obviously, adjust the min/start values as appropriate for your situation.
If you want, you could add a default constraint to the table/column with this:
alter table EXT01100 add constraint DF_EXT01100__Extender_Record_ID
default (next value for SQ_Extender_Record_ID)
for Extender_Record_ID
You mention that this is in a database whose schema you don't control, so that may not be an option; I mention it for the sake of completeness.
I have 2 databases in SQL Server, DB1 has multiple tables and some of the tables are updated with new records continuously. DB2 has only 1 table which should contain all the combined info from the multiple tables in DB1, and needs to be updated every 2 hours.
For example, DB1 has 3 tables: "ProductInfo", "StationRecord", "StationInfo". The first 2 tables both have a timestamp column that indicates when a record is created (i.e. the two tables are updated asynchronously, ONLY when a product passes all stations in "StationRecord" will "ProductInfo" be updated with a new product), and the last table is fixed.
The tables are as follows:
USE DB1
GO
CREATE TABLE ProductInfo
ProductID bigint Primary Key NOT NULL
TimeCreated datetime
ProductName nvarchar(255)
CREATE TABLE StationRecord
RecordID bigint Primary Key NOT NULL
TimeCreated datetime
ProductID bigint NOT NULL
StationID bigint
CREATE TABLE StationInfo
StationID bigint Primary Key NOT NULL
BOM_used nvarchar(255)
DB2 has only 1 table which contains a composite PK of "ProductID" & "StationID", as follows:
CREATE TABLE DB2.BOMHistory AS
SELECT
DB1.ProductInfo.ProductID
DB1.ProductInfo.TimeCreated AS ProductCreated
DB1.StationInfo.StationID
DB1.StationInfo.BOM_used
FROM DB1.ProductInfo
JOIN DB1.StationRecord
ON DB1.ProductInfo.ProductID = DB1.StationRecord.ProductID
JOIN DB1.StationInfo
ON DB1.StationRecord.StationID = DB1.StationInfo.StationID
constraint PK_BOMHistory Primary Key (ProductID,StationID)
I figured out the timing portion which is to use create a job with some pre-set schedules, and the job is to execute a stored procedure. The problem is how to write the stored procedure properly, which has to do the following things:
wait for the last product to pass all stations (and the "stationInfo" table is updated fully)
find all NEW records generated in this cycle in the tables in DB1
combine the information of the 3 tables in DB1
insert the combined info into DB2.BOMHistory
Here's my code:
ALTER Procedure BOMHistory_Proc
BEGIN
SELECT
DB1.ProductInfo.ProductID,
DB1.ProductInfo.TimeCreated AS ProductCreated
DB1.StationInfo.StationID,
DB1.StationInfo.BOM_used
into #temp_BOMList
FROM DB1.ProductInfo
JOIN DB1.StationRecord
ON DB1.ProductInfo.ProductID = DB1.StationRecord.ProductID
JOIN DB1.StationInfo
ON DB1.StationRecord.StationID = DB1.StationInfo.StationID
ORDER BY ProductInfo.ProductID
END
SELECT * from #temp_BOMList
INSERT INTO DB2.BOMHistory(ProductID, ProductCreated, StationID, BOM_used)
SELECT DISTINCT (ProductID, stationID)
FROM #temp_BOMList
WHERE (ProductID, stationID) NOT IN (SELECT ProductID, stationID FROM DB2.BOMHistory)
The Condition in the INSERT statement is not working, please provide some advice.
Also, should I use a table variable or a temp table for this application?
Try:
INSERT INTO DB2.BOMHistory(ProductID, ProductCreated, StationID, BOM_used)
SELECT DISTINCT tb.ProductID, tb.ProductCreated, tb.StationID, tb.BOM_used
FROM #temp_BOMList tb
WHERE NOT EXISTS
(SELECT * FROM DB2.BOMHistory WHERE ProductID = tb.ProductID AND StationID = tb.StationID)
I am trying to insert into 3 columns. The first columns needs an entry from another table, the second columns just needs a value and the third is NULL. So far I have this:
INSERT INTO PAT_CARAC ( NO_PATIENT, NO_CARACTE, DATEEXPIRA)
SELECT pp.NO_PATIENT,'16', NULL
FROM PAT_PATIENT pp
INNER JOIN PAT_CARAC pc ON pp.NO_PATIENT = pc.NO_PATIENT
WHERE pp.NO_CLINIQUE = 2;
I keep getting a PRIMARY or UNIQUE KEY constraint. Any help would be very much appreciated. Thanks!
Most probably your PAT_CARAC.NO_PATIENT field is primary key and your query is generating duplicate values
although you can try
INSERT INTO PAT_CARAC ( NO_PATIENT, NO_CARACTE, DATEEXPIRA)
SELECT DISTINCT pp.NO_PATIENT,'16', NULL
FROM PAT_PATIENT pp INNER JOIN PAT_CARAC pc ON pp.NO_PATIENT = pc.NO_PATIENT WHERE pp.NO_CLINIQUE = 2;
Postgresql:
I have two tables 'abc' and 'xyz' in postgresql. Both tables have same 'id' columns which type is 'serial primary key;'.
abc table id column values are 1,2,3 and also xyz id column containing same values 1,2,3,4
I want to union both tables with 'union all' constraint. But I want to change 'xyz' id column values to next value of 'abc' id column last value as 1,2,3,4,5,6,7
select id from abc
union all
select id from xyz
|id|
1
2
3
1
2
3
4
my wanted resuls as
|id|
1
2
3
4
5
6
7
BETTER - Thanks to #CaiusJard
This should do it for you
select id FROM abc
UNION ALL select x.id + a.maxid FROM xyz x,
(SELECT MAX(id) as maxid from abc) a
ORDER BY id
For anyone who's doing something like this:
I had a similar problem to this, I had table A and table B which had two different serials. My solution was to create a new table C which was identical to table B except it had an "oldid" column, and the id column was set to use the same sequence as table A. I then inserted all the data from table B into table C (putting the id in the oldid field). Once I fixed the refernces to point to from the oldid to the (new)id I was able to drop the oldid column.
In my case I needed to fix the old relations, and needed it to remain unique in the future (but I don't care that the ids from table A HAVE to all be before those from table C). Depending on what your trying to accomplish, this approach may be useful.
If anyone is going to use this approach, strictly speaking, there should be a trigger to prevent someone from manually setting an id in one table to match another. You should also alter the sequence to be owned by NONE so it's not dropped with table A, if table A is ever dropped.
This probably is a bit complicated but is there anyway or already a script out there that could show you all foreign key constraints tied to a single table row.
What I mean by this is say you have the following DB structure:
TABLE 1
column a
column b
TABLE 2
column c
column d (foreign key constraint to 1.a)
TABLE 3
column e
column f (foreign key constraint to 2.c)
TABLE 4
column g (foreign key constraint to 3.e)
column h
Then, you have 2 rows in Table 1. One of the rows is constrained through table 2, then further to table 3, BUT not further to table 4 (IDs tied throughout tables 1-3).
I would like to simply query one of the rows in Table 1 and have it tell me that for that row there are ties that go to Table 2, and then those rows have ties to Table 3. Using this 'query' on the second row in Table 1 would simply just return nothing as there are no foreign keys that are tying that row down.
Something like this would be immensely useful when it comes to tracking down what tables/rows are currently using a particular starting row.
Thanks!
I think what you're looking for can be accomplished by:
SELECT a, t2=COUNT(d), t3 = COUNT(f), t4 = COUNT(g)
FROM [1] LEFT JOIN [2] ON 1.a=2.d
LEFT JOIN [3] ON 2.c = 3.f
LEFT JOIN [4] ON 4.g = 3.e
