I'm trying to insert all data from Pacient table to Pacient_OR table (Object-Relational). Is there a simple way to do that (one script), if Pacient table has column with Pojistovna_ID (foreign key) and in Pacient_OR table there is REF to the Pojistovna_OR. Both Pojistovna and Pojistovna_OR are populated with the same data, but one is relational, second is based on object type.
I tried this (and more ofc):
INSERT INTO pacient_or
(pacient_or.id,
pacient_or.jmeno,
pacient_or.prijmeni,
pacient_or.datum_narozeni,
pacient_or.rodne_cislo,
pacient_or.telefon,
pacient_or.krevni_skupina,
pacient_or.rodinna_anamneza,
pacient_or.adresa,
pacient_or.pojistovna)
SELECT pacient.id,
pacient.jmeno,
pacient.prijmeni,
pacient.datum_narozeni,
pacient.rodne_cislo,
pacient.telefon,
pacient.krevni_skupina,
pacient.rodinna_anamneza,
Adresa_typ(pacient.ulice, pacient.mesto, pacient.psc),
(SELECT Ref(poj)
FROM pacient pac,
pojistovna_or poj
WHERE pac.pojistovna_id = poj.id)
FROM pacient;
This code throws error:
single-row subquery returns more than one row
Do not use pacient pac in the subquery. Link it to the pacient in your main from-clause. And even better do not use a subquery for this.

I need to insert data of one table to another table. All the values are from the table except one SO_ID. It is coming from the Item on the page. How do I do it?
insert into T_SORDER_ITEM_INWARD
(
select sd.ID, SO_ID
into :P25_SO_ID, sd.STOCK_ID,sd.ITEM_ID,sd.UOM_ID,
sd.ITEM_CONDITION_ID,sd.ORIGINAL,sd.ACTUAL,sd.WIDTH,sd.LENGTH,sd.STOCKQTY,
sd.KANTA,sd.RATE,sd.PACKET, sd.LABEL_METER, sd.EXCESS_SHORT,sd.LOCATION_ID,
sd.CLIENT_INITIAL, sd.FIN_YEAR, sd.SERIAL_NO
from T_STOCK_DETAIL sd join t_stock_master sm
on sd.stock_id = sm.stock_id
where sm.customer_id = p25_customer
)
A simplified example:
insert into another_table (id, name, location)
select :P25_SO_ID,
t.name,
t.location
from this_table t
Always name all columns you're inserting into (first line in my example).
Your query is impossible to understand. Not just because syntax is wrong, but because we have no idea which column is supposed to get which value.
I'm trying to copy data from a table called accounts into an empty table called accounts_by_area_code. I have the following fields in accounts_by_area_code: acct_num INT, first_name STRING, last_name STRING, phone_number STRING. The table is partitioned by areacode (the first 3 digits of phone_number.
I need to use a SELECT statement to extract the area code into an INSERT INTO TABLE command to copy the speciļ¬ed columns to the new table, dynamically partitioning by area code.
This is my last attempt:
impala-shell -q "INSERT INTO TABLE accounts_by_areacode (acct_num, first_name, last_name, phone_number, areacode) PARTITION (areacode) SELECT STRLEFT (phone_number,3) AS areacode FROM accounts;"
This generates ERROR: AnalysisException: Column permutation and PARTITION clause mention more columns (5) than the SELECT / VALUES clause and PARTITION clause return (1). I'm not convinced I have even the basic syntax correct so any help would be great as I'm new to Impala.
Impala creates partitions dynamically based on data. So not sure why you want to create an empty table with partitions because it will be auto created while inserting new data.
Still, I think you can create empty table with partitions like this-
impala-shell -q "INSERT INTO TABLE accounts_by_areacode (acct_num) PARTITION (areacode)
SELECT CAST(NULL as STRING), STRLEFT (phone_number,3) AS areacode FROM accounts;"
I am getting data from a feed file which is stored in Oracle Table TYPE.
Table TYPE created:
CREATE OR REPLACE TYPE typ_employee AS OBJECT
(
EMP_NAME DATE,
EMP_DEPT NUMBER,
EMP_SALARY NUMBER,
);
/
How can I find the unique records from this object and insert in another table.
Please help with this query.
You can use nested table and then use SET(Nested_table) which gives you distinct records in the nested table.
Or You can insert data from one table to another using cursor and use exception dup_val_on_index in exception block and you can skip that records (primary key should be added in second table) or update the existing one
I have a table that has one of its columns as a nested table.
I want to copy data of this table to another. How do we frame the INSERT clause for this seems challenging:
Consider. The field that is a nested table is phone_list whose type is a user defined type "TBL_PHONE_EXTN" which is a table of "typ_phone_extn".
CREATE OR REPLACE TYPE typ_phone_extn AS OBJECT
(phone_number VARCHAR2 (20), extension VARCHAR2 (10));
/
CREATE OR REPLACE TYPE tbl_phone_extn AS TABLE OF typ_phone_extn;
/
Obviously below fails: (with a ORA-00904: : invalid identifier)
INSERT INTO sch2.sub_pat_address (
pat_address_id,
pat_id,
**phone_list,**
last_updated_by
)
SELECT pat_address_id,
pat_id,
**phone_list,**
last_updated_by
FROM sch1.sub_pat_address ;
So i try:
SELECT pat_address_id,
pat_id,
**tbl_phone_extn(typ_phone_extn (phone_number,extension)),**
last_updated_by
FROM sch1.sub_pat_address, **table(phone_list)** ;
What this does is unnest the nested table. So i end up with more records than i want - meaning if a specific pat_address_id had a phone_list of 5 phone,extn combination this gives me 5 records that i cannot and should not be inserting.
So question is, how to keep the nest (nested table column) as-is and insert into the new table? Well, CTAS may be one option but that requires a whole new table instead of a INSERT. Any help will be greatly appreciated.
You can use the COLLECT function to reassemble the unnested elements into a nested table, casting that back to your actual collection type:
SELECT pat_address_id,
pat_id,
cast(collect(typ_phone_extn(phone_number,extension)) as tbl_phone_extn),
last_updated_by
FROM sch1.sub_pat_address, table(phone_list)
GROUP BY pat_address_id, pat_id, last_updated_by;
And you can then use that for your insert, obviously.
The only reason I can see you'd have a problem with your original simple insert would be if each schema had its own types and their tables were built using their own types. But then you'd get ORA-00932: inconsistent datatypes or ORA-01031: insufficient privileges rather than ORA-00904.
Even if you have privileges on the types across the schemas, Oracle UDTs have to be the exact same type - it's not enough for them to be constructed identically. If they are different entries in ALL_OBJECTS then they are not interchangeable.
I wanted to insert some initial data into the table in hive, so I created below HQL,
INSERT OVERWRITE TABLE table PARTITION(dt='2014-06-26') SELECT 'key_sum' as key, '0' as value;
but it does not work.
There is another query like the above,
INSERT OVERWRITE TABLE table PARTITION(dt='2014-06-26') SELECT 'key_sum' as key, '0' as value FROM table limit 1;
But it also didn't work, as I see that the tables are empty.
How can I set the initial data into the table?
(There is the reason why I have to do self-join)
About first HQL it should have from clause, its missing so HQL failure,
INSERT OVERWRITE TABLE table PARTITION(dt='2014-06-26') SELECT 'key_sum' as key, '0' as value;
Regarding second HQL, from table should have atleast one row, so it can set the constant init values into your newly created table.
INSERT OVERWRITE TABLE table PARTITION(dt='2014-06-26') SELECT 'key_sum', '0' FROM table limit 1;
you can use any old hive table having data into it, and give a hit.
The following query works fine if we have already test table created in hive.
INSERT OVERWRITE TABLE test PARTITION(dt='2014-06-26') SELECT 'key_sum' as key, '0' as value FROM test;
I think the table which we perform insert should be created first.
