Dropping a Table Using PL/SQL

I've read that PL/SQL doesn't support DDL, which seems to mean that I cannot use PL/SQL to create, alter, or drop a table. Is this true? I've written (but not tested) some PL/SQL code that needs to drop a table and rename another table under certain circumstances. Would this code work?:
IF archAlertCount = 0 THEN
     EXECUTE IMMEDIATE 'DROP TABLE ' || tName(x);
     EXECUTE IMMEDIATE 'RENAME ' || tName(x) || '_temp TO ' || tName(x);
     COMMIT;
ELSE
     ROLLBACK;
     END IF;
END LOOP;
I can't test it because my test environment isn't ready... that's why I'm asking instead of just trying it.
As always, I appreciate any responses.
Rebecca

Hello;
This Points you should have still in focus.
* Implicit Commit's with DDL's
your transaction before a DDL are automatically committed.
* Invalid Package
If your procedure references the Object, which should be dropped,
in static code it will get invalid.

How can one read a Excel File and Upload into Table using Pl/SQL Code.

How can one read a Excel File and Upload into Table using Pl/SQL Code.
1. Excel File is on My PC.
2. And I want to write a Stored Procedure or Package to do that.
3. DataBase is on Other Server. Client-Server Environment.
4. I am Using Toad or PlSql developer tool.

If you would like to create a package/procedure in order to solve this problem consider using the UTL_FILE in built package, here are a few steps to get you going:
1. Get your DBA to create directory object in oracle using the following command:
create directory TEST_DIR as ‘directory_path’;
Note: This directory is on the server.
2. Grant read,write on directory directory_object_name to username;
You can find out the directory_object_name value from dba_directories view if you are using the system user account.
3. Logon as the user as mentioned above.
Sample code read plain text file code, you can modify this code to suit your need (i.e. read a csv file)
function getData(p_filename in varchar2,
p_filepath in varchar2
) RETURN VARCHAR2 is
input_file utl_file.file_type;
--declare a buffer to read text data
input_buffer varchar2(4000);
begin
--using the UTL_FILE in built package
input_file := utl_file.fopen(p_filepath, p_filename, 'R');
utl_file.get_line(input_file, input_buffer);
--debug
--dbms_output.put_line(input_buffer);
utl_file.fclose(input_file);
--return data
return input_buffer;
end;
Hope this helps.

How to insert data in tables using loops sql

Oracle 10.2g
using Oracle sql*plus
Table student is
create table student(id)

This is the main part
There are 100 student id in the table
now i want to populate the table with sequences using seq.next_val
how to use a loop to insert 100 auto generated numbers in the table.
Thank you.
Expected result

.........Why i am doing this way instead of
create table student(no,id)

using distinct would throw an error.
create table student(st_id,id)

HI ,
1) If u want to select data from more the two table then u can use FOR ALL ENTRIES.
         EX ..Open sql
                   select matnr from mara into table t_mara.
                  select matnr werks from marc into table t_marc for all entries in t_mara where matnr = t_mara-matnr.
2) U can join more than one table.
           ex:
               select mara~matnr
                          marc~werks
                from mara join marc into table t_maramarc
                 on maramatnr = marcmatnr
3) Using native sql ...only u can use JOIN statement

Checking for every record in a table using PL/SQL

Hello Gurus,
I would need your help in finding the best approach to tackle the below analysis using PL/SQL.
I have a table which contains two columns
UserID and Month
I want to find out the users who made orders every month for the first half of 2012.That is the User ordered on Jan 2012, Feb2012 ... and June 2012.
The Table is huge and has more than a million records. How do I approach this in PL/SQL.
Joe

Hi Justin,
Thanks for the quick response. This is helpful.However my Intention is to do it using PL/SQL for learning purposes. I am new to PLSQL.
I wanted to do something like looping through each records in the table for every user ID and If I find orders for six consecutive months for a particular user, I will insert the user id to a temp table.
Any hints on how can I use this? I heard about cursor. Can I use it. If so how should I approach.

Polling records from mulitiple table(61 Tables) using WCF-SQL adapter

Hi,
I would like get some suggestion from this forum. I've a scenario, in which I need to poll the records from multiple table(61) which are related and may have one to many relationship. what's the best way to poll the records from SQL table to BizTalk.
Thanks in advance..
Regards,
Karthick

Karthick,
Write a SQL stored procedure with joins from your 61 tables (!!!) . Use WCF-SQL adapter to invoke the procedures.
Following references shall help you:
Executing Stored Procedures in SQL Server by Using BizTalk Server
Performing Composite Operations on SQL Server by Using BizTalk Server
Bing-Results: biztalk wcf sql
adapter polling stored procedure
I don’t know your exact requirement. Consider using SQL-SSIS for ETL process depending on your requirements. Anyway if your requirement really needs BizTalk, above suggest
should solve your problem.

How to find a dependent row in the all tables using single SQL query

hi all,
I have created some table with master and some dependent tables.I want to mark a (row)tuple as inactive in master so that corresponding child records also should be marked as inactive.
So i decided to mark the master and dependent records as inactive starting from master table and traverse to child tables.
So I need SQL query to fetch all dependend records to the row(marked row in the master ) from the master table and dependent rows from the child row and to mark as flag inactive.
can anybody help me out to build this query or any other way to mark flag as inactive ?
Regards
punithan

You can find dependant tables from ALL_CONSTRAINTS, e.g:
SQL> CREATE TABLE m (id INT PRIMARY KEY, flag VARCHAR2(1) NOT NULL);
Table created.
SQL> CREATE TABLE d1 (m_id REFERENCES m, flag VARCHAR2(1) NOT NULL);
Table created.
SQL> CREATE TABLE d2 (m_id REFERENCES m, flag VARCHAR2(1) NOT NULL);
Table created.
SQL> SELECT table_name, owner, status
2 FROM   all_constraints c
3 WHERE c.constraint_type = 'R'
4 AND    ( c.r_owner, c.r_constraint_name ) IN
5         ( SELECT owner, constraint_name
6           FROM   user_constraints
7           WHERE table_name = 'M'
8           AND    constraint_type IN ('U','P') );
TABLE_NAME                     OWNER                          STATUS
D2                             WILLIAMR                       ENABLED
D1                             WILLIAMR                       ENABLED
2 rows selected.There is no SQL command to apply all updates in one go, if that's what you were looking for.
AFAIK the word "tuple" is for mathematics and relational theory, and does not refer to a physical row in a database.

Inserting data from one table into another table using PL/SQL

HI,
I am trying to insert values from one table into another using PL procedure, the values I want to retrieve from the table riverside1 are charac_id and charac_type and insert these values into another table called riverside2 , the stored procedure zorgs_gorfs(x,y) accepts two parameters which are 2 charac_id's of d characters in riverside1 then using insert statements inserts these characters from riverside1 into riverside2.
CREATE OR REPLACE PROCEDURE zorgs_gorfs(x IN NUMBER, y IN NUMBER) AS
     BEGIN
          INSERT INTO riverside2
               (charac_id)
          VALUES
               (x);
INSERT INTO riverside2
               (charac_id)
          VALUES
               (y);
      END zorgs_gorfs;
/This works but the problem im having is that when I also try to insert the charac_type as well as the charac_id it doesnt work below is the code:
CREATE OR REPLACE PROCEDURE zorgs_gorfs(x IN NUMBER, y IN NUMBER) AS
     BEGIN
          INSERT INTO riverside2
               (charac_id,charac_tye)
          VALUES
               (Select
                    charac_id,
                    charc_type
               FROM
                    riverside1
               WHERE

Accessinng Table using Native SQL in ABAP Program

Hi Experts,
I need to access a table that is created in Oracle.
But while writing a select query as below:
EXEC sql.
   SELECT MAX(ID_EVENTO)
     INTO :LV_ID_EVENTO
     FROM ZTAB.
ENDEXEC.
I am getting a dump saying "ZTAB doesnot exist" or IF I use ZTAB@ifsap then it dumps saying "Database name is missing a component".
Do I need to add some suffix to the table name like @ifsap to ZTAB?
Also, can I use SY-SUBRC to check to the success and failure for SELECTION OR INSERTION Operation?
Thanks

Hello,
Try using SAP<SID>.ZTAB in your query.
For example SAPC05.ZTAB
