SQL Developer - Migrate Access to Oracle

ckw460Oct 16 2013 — edited Oct 16 2013

Attempting to migrate a MS Access (accdb) database to Oracle 10g. 

Using SQL Developer Version 4.0.0.12 Build MAIN-12.84. Tools, migration, migrate.

Step 1, use the stand alone MS Access export tool to generate file to use in offline capture mode (omwb2007).

Step 2, repository schema set up in Oracle for the model.

Step 3, Migrate, migration and follow the wizard, using the offline option and pointing to step 1.

Including data.

First run generated an error, taken from MIGRLOG table, last 3 rows:

NullPointerException, Capture

Convert,null

Performing column default clause translation: FAILED : Database Migration : FAILED

Checked the XML file generated by step 1 and the log file generated from step 3. Looked at the Access database and removed some queries that were not required. Also removed modules and macros.

Ran through the steps again.

The process failed again, curiously at the same point, exactly the same number of rows in the log table, even though a different number of queries in MS Access on second run.

Ideas, thoughts appreciated

Hi, User_4G3I3
Whenever you have a question, please post a little sample data (CREATE TABLE and INSERT statements for all tables involved, relevant columns only) so the people who want to help you can re-create the problem and test their ideas. For PL/SQL questions, include a complete working block that does the parts you already know how to do. Also post the exact results you want from that data, and explain why you want those results from that data. Always post your complete Oracle version (e.g. 18.4.0.0.0).
So how can I detect every new ID 
Create a variable to hold the value of the previous id. Initialize it to something that can not be a value of id. Inside the beginning of the loop say

IF  id = prev_id THEN ...

At the end of the loop, say

prev_id := id;

Alternatively, you could add a column in the query that tells if a row is the first row for the id, using an analytic function such as LAG or ROW_NUMBER.

First of all there is no row order in relational table. Order is provided vi ORDER [SIBLINGS] BY clause. So I will assume rows for same ID should be ordered by PAYMENT. Then there is no need to PL/SQL. All you need is:

SELECT  ID,
        MIN(PAYMENT)
  FROM  YOUR_TABLE
  GROUP BY ID
  ORDER BY ID
/

Sorry, I am new to this community and I will follow your guidelines next time :)
Here is the block of code. I am using the database from this textbook (Oracle 11g pl sql programming 2nd edition casteel)
SQL developer Version 21.2.1.204 Build 204.1703
Oracle Database 18c Enterprise Edition Release 18.0.0.0.0 - Production

Again, post CREATE TABLE statement and INSERT statements to populate it. Nobody wants to waste time on typing.

Ignore the drop table part at the top, I forgot to remove it.

Most people will not open files from unknown sources. Post it, not attach it.

@Frank Kulash
Thank you, ROW_NUMBER solved my problem.
