SQL & PL/SQL :: How To Create Dynamically ALTER INDEX Command
Nov 15, 2010
how I can create an index dynamically? The DBA wants me to put this code below in the beginning of a PL/SQL package. At first, I tried by just putting the below syntax in the code, but I get an 'Alter' is not a valid identifier.
alter index ZZAP_selected_invoices_n1 rebuild online;
i need a trigger with alter commands to alter the table structure,it will be captured in a separate meta data table(META)
CREATE OR REPLACE TRIGGER meta_alter AFTER Alter ON SCHEMA BEGIN update meta set column_name=:new where table_name=ora_dict_obj_name column_name=:old; END; /
Meta table contains Table name and column name..i attached the table data in atext file
How to dynamically execute a select command whether it is retrieved a single record or multiple record in oracle database 10g. i have tried with the command execute immediate but it was not successful.
is it possible can i delete or drop multiple tables in a single drop and delete statement.
I've heard that this statement causes a table lock but cant find any information on this.if it is so, is it a write lock or also a read lock of the table?
In a pl/sql procedure code, I created a normal table (create table) using dynamic sql. Then I used that table in procedure for further processing. But while compiling, it gave error that table does not exist. I can understand that he table is not present in DB, so the error came. But at the same time I need to create a table dynamically, use it and drop it. Does it mean that I need to make every query referencing that table as dynamic ??
1) how to find a primary key of a table in oracle, for example if I want to drop a index in table , how do I find what is the primary key in a table so that I can issue that command.
P/s: I don't have OEM installed so I must use SQL command
Example of dropping the index ALTER TABLE table_name drop CONSTRAINT constraint_name;
i need to create a replica of an existing table in same schema dynamically so as to reflect the modifications on replica table which has been done on primary table.this table we need to maintain as snapshot,like if a column is added or deleted then it should automatically be added or deleted on the replica table.how should i approach this.
I have created a procedure to build trigger dynamically using Dynamic SQL. Here procedure created successfully, when we execute the procedure to build trigger getting the following error.
Note: We are able to create a Trigger, but it is INVALID. if we get the code of a trigger and execute, trigger created a successfully with Valid Status.
ERROR: ORA-24344: success with compilation error ORA-06512: at "APPS.CREATE_TRIGGER", line 28 ORA-06512: at line 2

I need to load data from a CSV file where one of the CSV values determines how many records should be inserted.
Example of the input data:
KEYWORD;2;REC1_COL1_X,REC1_COL2_X;REC2_COL1_X;REC2_COL2_X KEYWORD;3;REC1_COL1_Y;REC1_COL2_Y,REC2_COL1_Y;REC2_COL2_Y;REC3_COL1_Y;REC3_COL2_Y KEYWORD;4;REC1_COL1_Z;REC1_COL2_Z,REC2_COL1_Z;REC2_COL2_Z;REC3_COL1_Z;REC3_COL2_Z,REC4_COL1_Z;REC4_COL2_Z If the KEYWORD is found, then the next value determines how many value pairs will follow, and therefore how many rows should be created in the affected DB table.
We have certain records like SQL, PL/SQL, Reports, Forms, OAF etc in a table. We wanted to capture rating for each of these criteria. So we want a form to be displayed dynamically..
I want to creat a table using Execute Immediate that includes tablespace name in the create table command. But I don't know the tablespace name that the client is using. Can I incorporate in a script? If yes, then how?
I have written the following proc. While executing , it gives me the error: ORA-00959: tablespace 'V_TABLESPACE_NAME' does not exist.
create or replace procedure pr_create_table as v_tablespace_name varchar2(4000); begin select distinct tablespace_name into v_tablespace_name from user_tables where table_name like 'ABC%'; [code]....
The way to create a short cut on desktop to have an sql*plus (command line).
i.e. I want to have an short cut on desktop when I click that short cut that would connect me to a specific database with a username and password (which i supply while creating the shortcut-I would provide the database name, username and password)
i want to create a bitmap index,but getting the error shown below..i created primary key on column dname of dept and unique constraint on empno of emp.
SQL> create bitmap index bindx on dept d(d.dname) from emp e,dept d where e.deptno=d.deptno; create bitmap index bindx on dept d(d.dname) from emp e,dept d where e.deptno=d.deptno * ERROR at line 1: ORA-25954: missing primary key or unique constraint on dimension
difference between the ways we create Reverse Key Index on the table.The two ways are as below:
1) CREATE INDEX <Index_Name> ON <Table_Name>(<Column_Name) REVERSE ; 2) CREATE INDEX <Index_Name> ON<Table_Name>(REVERSE(<Column_Name>)) ;
Which one is the appropraite one. Are both going to act in the same way.
I created index in both ways one by one on the table.But when I fire the select statement against the same table, The explain plan doesn't show any cost and it shows the full table scan in both ways.The select statement used is as below...I want to compare the column with string RBO(i.e('RBO%') at the start.
SELECT * FROM <Table_Name> WHERE REVERSE (<Column_Name>) LIKE '%OBR' ;
The select statement is giving me the correct result. Only the explain plan is showing Full Table Scan.can we use this reverse with IN operator also in the same way by reversing the values.
I use Oracle 10.0.2.0.1.If I create a table with constraint key; after that I create an unique index key, I got an error. Does it mean when I create a table with constraint the unique index are automatically created and I could not create index key as I did as below?
create table test_const(ename varchar2(50) not null, key_num number not null, descr varchar2(100), constraint constraint_test_const unique (ename, key_num)); create unique index test_const_idx on test_const ( "ENAME","KEY_NUM" ) tablespace tmp_data;

This unselective index scan on step 36 of the explain is returning 14 rows but optimizer is selecting 3064 K rows from the table .
I tried creating combined index on all 3 columns mentioned in the predicates for 35th step , but that is not utilized .
how to index this whole expression ::--
(ACCNT_FLG<>'N' AND (INT_ORG_FLG<>'Y' OR PRTNR_FLG<>'N'))
Something like CREATE INDEX XYZ on table((ACCNT_FLG<>'N' AND (INT_ORG_FLG<>'Y' OR PRTNR_FLG<>'N')) compute statistics ;
Is it a possible to create table using clause below together with index ?

I got procedure which create a table in the schema B. The procedure is called from schema A. But when I write into procedure query for create index then I got a error:
ORA-01031: insufficient privileges when ...executing
Therefore I think about to create table together with index.
