PL/SQL :: Table With Union All And Using Having Statement?
Sep 18, 2012
I am writing a query and I did get it to work but it shouldn't be this hard, I feel like I am doing something wrong, and there has to be a more elegent solution.
This query works:
SELECT a.d
FROM (
SELECT S_ID a, LOOKUP_DESC d, S_CODE f
FROM SSS
JOIN LOOKUP ON S_CODE LIKE LOOKUP_CODE
UNION ALL
[Code]...
I feel like I should be able to execute the query like this: This query doesn't work:
SELECT a.d
FROM (
SELECT S_ID a, LOOKUP_DESC d, S_CODE f
FROM SSS
JOIN LOOKUP ON S_CODE LIKE LOOKUP_CODE
1DGT_ITEMEFFORTDATA_DAILYHCLT_IDX_DGT_IFDITEMID4 2DGT_ITEMEFFORTDATA_DAILYHCLT_IDX_DGT_IFDITEMTYPE3 3DGT_ITEMEFFORTDATA_DAILYHCLT_IDX_DGT_IFDOWNERID2 4DGT_ITEMEFFORTDATA_DAILYHCLT_IDX_DGT_IFDOWNERTYPE1 There is no index on DGT_ITEMEFFORTDATA_TEMP table
I have a view, which has a union. (Union is required because of the nature of the data fetched). THis view is later joined with a global temp table which holds the -say employee Id the user selects.
So at runtime there is a join with the global temp table and the view. But the performance is really bad. I have tried using various hints, like materialize, /*+ CARDINALITY(gtmp 1) */ etc.
When i query the view alone,. the performance is good. When I remove the union, the performance is good. Some how with the union- there is a full table scan on one of the joining tables.
finally add a HINT /*+ gather_plan_statistics push_pred(TABLE) */ and the result was not very good in this case, but improved the resolution of the view, the rest got worse
SQL Statement from editor: SELECT /*+ gather_plan_statistics push_pred(o10475761) */ COUNT(o10475761.SUC_ID) FROM GAR_DW.ARTICULOS o10475528, GAR_DW.EMPRESAS o10475602, GAR_DW.L_DIA o10475639,
HOW to use variable P_TMPLID in following statement
TYPE typ_unrecon IS TABLE OF REC_' || P_TMPLID ||'_UNRECON%ROWTYPE index by binary_integer;
because its throwing error while compiling
and also in statement FORALL i IN unrecondata.FIRST .. unrecondata.LAST SAVE EXCEPTIONS --STRSQL := ''; --STRSQL := ' INSERT INTO REC_' || P_TMPLID ||'_UNRECON VALUES ' || unrecondata(i); -- EXECUTE IMMEDIATE STRSQL; INSERT INTO REC_' || P_TMPLID ||'_UNRECON VALUES unrecondata(i);---throwing error on this statement commit; --dbms_output.put_line(unrecondata(2).TRANSID); EXCEPTION
I want to know the DDL statements executed on a table. Example:
i have a table test1 with structure as below: test1 (aa number, bb varchar2(10))
After some period of time, one DDL statement to alter the column is issued.
alter table test1 modify (bb varchar2(30));
so new table structure is: test1(aa number, bb varchar2(30))
Basically i would like to find these 2 DDL statements executed on this table - test1, so that i compare which column get modified and what modification done.
Is this information stored in any data dictionary table?
note - audit, flashback option not enabled in this database.
I have a table TEMP_TEST_1 to be loaded with multiple rows which contains the available items for a store with their sequence numbers. I also have another table TEMP_INV_1 which holds a column for inventory count of the items, and this column is to be updated after loading the first table TEMP_TEST_1.
The table TEMP_TEST_1 is updated through all possible channels in OLTP. So while updating the inventory, which is the best way. My update should either add the total number of inserts per item into the TEMP_TEST_1 table's INVENTORY_CNT column i.e. existing value + count of new rows OR a full update by taking the complete row count (Grouped by item id) and update the INVENTORY_CNT column
-------------------------------------------------------------------------------- -- Initial setup SQL's, TEMP_TEST_1 is updates on OLTP through multiple channels -------------------------------------------------------------------------------- CREATE TABLE TEMP_TEST_1 ( ITEMID NUMBER ( 4 ), INVENTORY_CNT NUMBER ( 2 ) ); CREATE TABLE TEMP_INV_1 ( ITEMID NUMBER ( 4 ), ITEMSEQ NUMBER ( 5 ) ); INSERT INTO [code].......
-------------------------------------------------------------------------------- -- Inserts for new items in the store -------------------------------------------------------------------------------- INSERT INTO TEMP_INV_1 VALUES ( 1, 11 ); INSERT INTO TEMP_INV_1 [code].......
i'm trying to use a collection in a select statement as a table, but i've got an error which i don't understand.
This exemple is very simple. I'm trying to validate the solution. The object will contain the result of a query from a big table, and i have 4 request to make on it. I don't want to select 4 times the big table to get the result, but i need the whole result to make my requests (intersect, minus and union)
CREATE OR REPLACE TYPE zy_w AS OBJECT( CODE_INFORMATIONVARCHAR2(4),

this is the correct syntax for updating a table with a select statement included. Table created easily and the alter table ran fine, but the update is running quite a log time.
My ultimate goal is to populate the "children" field with a count of children for each household id.
create table NON_GBC_Members nologging as select distinct hcp.household_master_ID from mrtcustomer.household_child_profile hcp where hcp.child_birth_dt between '31-OCT-2000' and '30-OCT-2011' group by hcp.household_master_id minus

My requiremen is if record is exists then i wan to update some value, if record not existes the i wan to insert new record
create table SELECTION_BOOKMARK( INSTALLATION_ID SMALLINT NOT NULL, BOOKMARK_ID SMALLINT NOT NULL, NAME VARCHAR2(50) NOT NULL, SORT_ORDER SMALLINT NULL );
When I execute this statement as part of a SQL script, it throws the error "ORA-01003: no statement parsed". If I execute it as a stand alone sql command, it returns no error.
Here's the strange thing, though. Even when it throws the error message the table is created. Later on in the script, I execute the following command:
alter table SELECTION_BOOKMARK add primary key(INSTALLATION_ID,BOOKMARK_ID);
This command also throws the above mentioned error, but once again the command executes - the primary key is created.Well, I don't like having a script that throws errors. Eventually I'll have to give this script to a dba in another organization and I don't want my script to be throwing errors - even if it's apparently working correctly despite the errors.
I want to grant a privilege through an insert statement into a sys table.Why do not grant the privilege through the classic way : grant select on t to l_user; ?
Because I want to do it remotely.I am connected to db1.I want to grant select on t2 to u2_b from u2_a.I assume that all DDL are DML. So a grant is equivalent "somewhere" to an insert.I tried to do my requirement locally, and here is the output.
SQL> conn scott/aa Connecté. SQL> -- step 1 : try to grant "normally" a select on dept to hr from scott SQL> grant select on dept to hr;
Autorisation de privilèges (GRANT) acceptée.
SQL> SQL> conn sys/a as sysdba Connecté. SQL> -- step 2 : Then, we connect to sys to see the row inserted in dba_tab_privs SQL> SQL> col GRANTEE format A10 SQL> col OWNER format A10
[code]...
Then if I can do it locally, I can do it remotely through a db link.
We are firing a normal Drop command on our database and the database version is 10.2.0.4.The database is running on AIX v5.The command is taking more time than usual .
When i am monitoring the session i can see that a call is being made to procedure "aw_drop_proc".Could i ask you if this is something that is taking more time than usual.
We are not having any partitions on the nested tables .We have a pack of tables and we are dropping this pack through a procedure.The pack comprises of nested tables & normal tables.To drop a nested table it is taking around 6 seconds(Table with no rows) and a normal table(With no rows) it is taking 17 milli seconds.We have a partition on Normal table.
The same operation in windows is taking very less time when compared to AIX.
I have a large table and want to calculate just a few values. Therefore, I don't want to create a new table, I want to update the table. Here an example:
I want to calculate the VALUE_LAG with ID = 4 only (-> two values).
create table zTEST ( PRODUCT number, ID number, VALUE number, VALUE_L1 number );
[Code]..
I tried this, but obviously, windows functions are not allowed in the update statement.
update zTEST set VALUE_L1 = lag(VALUE) over (partition by PRODUCT, order by ID) where ID = 4
I've to create a table which has 650 fields and the total length of CREATE TABLE statement got to be more than 4000 characters.I've to create the table by inserting the CREATE TABLE statment in a variable (V1) then by using EXECUTE IMMEDIATE V1 Since VARCHAR2 only supports upto 4000 characters length string, how can I create such table??
DECLARE V1 VARCHAR2(4000); BEGIN V1 := -- CREATE TALBE STATEMENT WITH LENGTH MORE THAN 4000 EXECUTE IMMEDIATE V1; END;

how to play around with NDS dynamic sql and I'm trying to add a column on the fly.Basically the procedure is trying to take a table name, column name, and eventually a data type and adds it to a table.
It works fine without the bind variable for the column name, accepting the table name on the fly.As soon as it tries to use the column name I get an ORA-00904 invalid identifier exception.
Here is the procedure I'm using
CODEcreate or replace procedure test(tbl_name varchar2, col_name varchar2) IS qry varchar2(500); begin
In a trigger(on update of a table t1) I am trying to write, I am doing an insert on t2 accessing ':new' values of the update on t1.
But in my Insert statement, I am having get one of the column values from another table. How can I write my insert statement in such a way as to insert values contained in ':new' pseudo columns and a select from another table. Below is my insert statement in the trigger : -------
IF (:old.GROUP_YELLOW <> :new.GROUP_YELLOW) THEN INSERT INTO TEST.W_THRESHOLD_LOG (THRESHOLD_LOG_WID, CHANGE_DATE, MEASURE_TYPE_WID, MEASURE_NAME, CUSTOMER_WID, CUSTOMER_NAME, USER_ID, CHANGED_ITEM, PREV_VALUE, NEW_VALUE) VALUES(TEST.W_THRESHOLD_LOG_SEQ.NEXTVAL, SYSDATE, :new.MEASURE_TYPE_WID, 'Rolling Stabilty' , :new.CUSTOMER_WID, 'Customer1', 'User1', 'GROUP_YELLOW', :old.GROUP_YELLOW , :new.GROUP_YELLOW); END IF; -------
In the above code if the hardcoded value 'Customer1' need to be picked from another table, i.e .
SELECT NAME FROM W_CUSTOMER_DIM WHERE CUSTOMER_WID = THRESHOLD.CUSTOMER_WID
how can I rewrite my query to the above value from the select into my insert statement..?
I have been trying to use case statements with oracle table type by really not sure how to go about it. I know it might be simple but it been giving me hard time.
Here is my Cursor:
CURSOR c_chk_style IS SELECT DISTINCT 1 FROM TABLE(CAST(I_message.ExtOfXOrderDesc_TBL(1).ExtOfXOrderSkuDesc_TBL AS "RIB_ExtOfXOrderSkuDesc_TBL")) item_diff,
[code]...
Now i know that the table type "RIB_ExtOfXOrderSkuDesc_TBL" will be always populated but the table type "RIB_ExtOfXOrderPackDesc_TBL" may not be populate and can be null. So i want to run the exists against the "RIB_ExtOfXOrderPackDesc_TBL" aliased pack_diff only if it is populated. If its null i dont want to run the exists clause.
- returning from the procedure 2 ref cursors containing result set of 2 queries - returning from the procedure 1 ref cursor containing result set of that 2 queries as one (with UNION ALL)?
I have a query which has 5 unions, each clause of the union takes 1 hr to run and query results come back in 5 hrs, Is there any way I can make these clause to run in parallel?
Below is my query Issue faced is that based on union I want to limit the result and does not want second query to give duplicate result as both queries deal with same table
SELECT TAB1.ID, TAB1.CRNCY_CODE, TAB2.SCHEME_CODE, DECODE( 'INFENG',CAST( '' AS VARCHAR(20)), NVL(TAB2.ALT1_SCHEME_DESC,TAB2.SCHEME_DESC),TAB2.SCHEME_DESC), TAB1.SUB_HEAD_CODE, DECODE( 'INFENG' ,CAST( '' AS VARCHAR(20)),NVL(TAB1.ALT1_SUB_HEAD_DESC , TAB1.SUB_HEAD_DESC),TAB1.SUB_HEAD_DESC)
[code]...
select null ID,null crncy_code,TAB2.SCHEME_CODE , NVL(TAB2.ALT1_SCHEME_DESC,TAB2.SCHEME_DESC),TAB2.SCHEME_DESC,null SUB_HEAD_CODE from TAB2 where TAB2.SCHEME_TYPE ='SCHEME1';
I'm just trying to see if there is another way of doing this query without using a UNION. The only way I can see is using a UNION but maybe I'm missing something or a way to do it without a UNION.
Result:
Select any customer within the user_states table who lives in "MO" Select any customer within the user_cars table who lives in "MO" and has a "White" car Select any customer within the user_plates table who lives in "MO" and has a plate of "A" or "B" Join to the user_names table to display the customers name
So, the result would be any customer who lives in "MO" who owns a "White" car and any customer who lives in "MO" who has a plate of "A" or "B".
