There is a table with almost 60 million records. This is a temporary table or rather a staging table. I want to be able to split the table into two tables. This is an example of what the staging table looks like.
1. The straightforward loop. Read each record > Go through table 1 , get a count of similar records> If exists, use that ID to populate detail table > If doesn't exist create a new ID and populate the detail table
2. Use two cursors. First cursor goes through all the records (*). Takes 1 line, creates an ID on 1st table. Second cursor finds all records that are similar to the first line. Populates the detail table using the ID and then deletes currently inserted rows from the staging table.
I have got the first idea working. It works fine but takes forever since it has to go through the whole table for selecting the count for each record.I tried implementing the second idea but I believe the cursor creates a snapshot of table at runtime so within the loop if it finds out record has been deleted, throws me an error.
I'm needing to pull data into a cursor, then split this data into 3 different tables, each having the same number of rows and a select number of columns from the original. i can pull the data, but then i can only access it one row at a time via FETCH, then i can't load into the 3 new CURSORS one row at a time.
i'm working on this database assignment...and basically, no matter what I do my table seems to automatically split into a different table after 8 rows...i've tried googling it and using commands like....
set wrap off; set numwidth 20;
and fiddling with the format of each column but nothing seems to work...i just want my table to show as one table
here's my script create table patient (patient_number number(4) primary key, patient_name varchar(15) NOT NULL, address varchar(30) NOT NULL, telephone number(7) NOT NULL, patient_status char(1) NOT NULL, next_appt date, balance number(5,2), CHECK (balance >= 0), CHECK (patient_status='N' OR patient_status='A' OR patient_status='I')); [code]...
12 rows selected.the columns are actually aligned so don't worry about that...it's just the splitting of the rows.
I've an Oracle Table which has around 300 columns. I've a requirement to split this single table into two tables (150 columns each) by a foreign key.
Now I want to know how to maintain the data integrity while I insert the data into two tables. which means each table should have equal number of rows as we insert the 300 columns data into tables each at a time.
I have two tables T1 and T2. T1 is the original backup snapshot for changed records from overnight batch in a big table and T2 is the overnight batch changed records. Both tables have similar number of rows (T2 might have more for newly inserted rows) and you can find out the differences by comparing these two according to action column in T2 (C - Update, A - Insert and D - Delete)
how to compare these two tables to generate something like the following. I can join these two tables to generate the diff but it is one row per account.
client_nbr branch_cd, account_cd, action column, old_value, new_value 8888 123 45678 C account_clsfn_cd 004 005 8888 123 45678 C buy_cd 98 99 8888 012 34546 A sell_cd 12 8888 321 98765 D dividend_cd 1
I am using Oracle 10g so Unpivot cannot be used.
CREATE TABLE T1 ( CLIENT_NBR CHAR(4 BYTE) NOT NULL, BRANCH_CD CHAR(3 BYTE) NOT NULL, ACCOUNT_CD CHAR(5 BYTE) NOT NULL, ACCOUNT_CLSFN_CD CHAR(3 BYTE), SELL_CD CHAR(2 BYTE), BUY_CD CHAR(2 BYTE),
Region Code,Name,Surname,ID_Number 1,John,Doe,67 1,Sarah,Jason,45 2,Bob,Marley,69 3,Steven,Johnson,900 2,Harry,Potter,890 3,Sandy,Bay,567 3,Else,Taylor,789 .....
I have about over 100 region codes and each region would like to get their own data. I can manually do the extraction and create a new table for every region, but it's going to take too long.
We are adding support for barcode scanner in one part of our information system. So that the mechanics can add parts to an work orders bill of material themselves using barcode scanner to scan the part and enter the qty.
I can via SQL add a part to the bill of materials and reserve the part. But then the part needs to be issued to make it disappear from the stock.
I have found a table that contains information about the part and the bill of material, it has a column named "QTY ISSUED" I have tried via an update command to set the qty issued = 1 for the reserved part. The table is updated, and via SQL everything looks fine, but the part doesn't disappear from the stock. So my guess is that there is a trigger or function somewhere that I need for this.
I have 2 tables that doesn't have primary keys. These 2 tables have same number of rows. I want to create a new table from getting some columns from table1 and some columns from table 2. I want to combine first row from table1 and first row from table2.
Below is example
TABLE1
ACOL1 ACOL2 ACOL3 A1 A2 A3 B1 B2 B3 C1 C2 C3
TABLE2
BCOL1 BCOL2 BCOL3 11 12 13 21 22 23 31 32 33
COMBINED_TABLE
ACOL1 BCOL2 BCOL3 A1 12 13 B1 22 23 C1 32 33
I tried below query but no luck. It gives below error:
Query : create table COMBINED_TABLE AS select a.ACOL1, b.BCOL2, b.BCOL3 from (select ACOL1,rownum from TABLE1) a, (select BCOL2, BCOL3, rownum from TABLE2) b WHERE a.rownum = b.rownum
Error : ORA-01747:"invalid user.table.column, table.column, or column specification"
How does one select * from one table without selecting * from other tables that are included in a query? For example, if in the query below I want to view all fields in some_table, but not the fields from other_table, how do it?
select * from some_table st, other_table ot where st.id = ot.id
I have 2 tables as shown below. I have to join those tables and get data as in table 3. Condition is I have to get sum of scores for each student where category is 1 and active is Y.
Table1: col1col2category A 10 1 A 10 2 B 10 1 B 20 2 C 10 1 D 20 1 J 30 1
Table2: colAcolBActive A10Y A20N B30Y B40N Z35Y
Table3: STUDENTSCORE A20 B40 C10 D20 J30 Z35
query to show student name and sum of his score where category is 1 and active is Y. I am using Oracle 8i.
I want to read 1 table. If the date is less than today, I want to update 4 other tables. I only want to do this update once a day.
While the 4 other tables are being updated, I want the other web users to pause for the update while this procedure runs.
Is there a better way to do this?
Here is what I have:
CREATE OR REPLACE PROCEDURE TEST_TODAY2 AS -- to create the table -- create table test_today(updated_date date); -- insert into test_today(updated_date) values (sysdate-1); -- select * from test_today; cursor daily_update_cur is select updated_date from test_today for update of updated_date;

I have 2 tables Table a(girlscoutid, item, quarter)Table b(girlscoutid, fname, lname) I want to get the names of ppl who did not sell any item/s for the
PROCEDURE COLUMN_SPLIT (p_def IN VARCHAR2, p_sch OUT VARCHAR2, p_table OUT VARCHAR2, p_column OUT VARCHAR2) IS BEGIN NULL; END; END;
I want to split p_def by dots, check for 3 elements, and return them in p_sch, p_table and p_column for example p_sch will be like hello.howare.you.I want to split it to hellohowareyouI have very limited knowledge with pl/sql.
I have to reorganize one table that related to several other tables. The reorg is too slow when it runs on this table. I would like to create one image of the table and synch it with the original one in real time. So when I run the reorg, I will use the image table that does not constrained by indexes and other objects. Once the reorg is done, I would like to rename the table. how could I do the replication in real time?
I need to implement the foreign key on a column of a table from 2 tables. My requirement is in bellow.
drop table t1; create table t1 (slno number, acc_no number);
drop table t2; create table t2 (acc_no number primary key, acc_name varchar2(100));
drop table t3; create table t3 (acc_no1 number primary key, acc_name1 varchar2(100)); [code]...
It is provided that the values of acc_no in t2 and acc_no1 in t3 are unique.Now it required that while inserting into t1 , the system will check either t2 or t3 tables.
I have one control table as below.I want to rebuild all indexes for the tables in control table.
The control table is having the following data.
SEQ_IDTABLENAME SCHEMA_NAME 1GEDIS_ORDER_FORM_STATES ALL 2GEDIS_NOTES ALL 3GEDIS_CARD_TYPE_AUDIT APRT 4FAX_HEADER OMS
In the control_table schema_name "ALL" means this is for 30 schemas(The table is existed in 30 schemas).Except for schema_name "ALL" ,the table is existed in the particular schema(The table is existed in the only one schema).
I tried the following code it is executing for all 30 schemas(ALL).But it is not executing for specific schemas.
CREATE OR REPLACE PROCEDURE Rebuilding_index IS l_sql VARCHAR2(4000); CURSOR cur_tab_schema IS SELECT tablename,schema_name FROM control_table3;
In a query can we have the same alias for more than 1 table as in the following example
Select C.ContractNum, B.Billnum, B.Billamt,A. From Contractmaster C, Billdetails B, Address A, Currencymaster c, Where B.billtype = 1 and C.Contractnum = B.Contractnum and C.customerref = A.Customerref and c.currencycode ='EUR'
In the above query, Table Contractmaster has an alias C --in capitals while table Currencymaster has an alias c - in small caps ...
Is this possible in Oracle 11g ? Also i found that the table Currencymaster has no Join conditions I executed the query, without any errors!
I have a string like '9999999;A' one field as numeric & other as char.Now i want to split this string into two values removing the ; delimiter in oracle using for loop.
Insert into temp_a values ('1','002.0 AND 002.9'); Insert into temp_a values ('2','729.90 AND 079.99 AND 002.9');
Output :
1 002.0 1 002.9 2 729.90 2 079.99 2 002.9
So, once we get the output, it needs to be joined to another table. I did Google search, but most of them are retuning collections / arrays as output. Not sure how I join the collection with the table.
