What Is Key Generation In Bods
Key Generation Transform generates the surrogate keys.The Generated Key Column option on the table comparison does not generate the keys rather we simply specify the Generated Key Column there. Sep 12, 2013 Key Generation transform helps to generate artificial keys for new rows in a table. The transform looks up the maximum existing key value of the surrogate key column from the table and uses it as the starting value to generate new keys for new rows in the input dataset.
- Feb 29, 2012 Although the Key Generation Transform actually does execute a SQL I put it into the Streamline category because it executes one and only one SQL at the start of the transform and this is a 'select max(key) from table'. In almost all cases this key will be the primary key column which is indexed.
- Feb 24, 2014 what is the difference between row generation and key generation transform? In which scenario we need to use row generation transform and key generation transform in BODS. Note: I am using BODS 4.0 version.
- Jan 30, 2013 Post subject: Re: keygeneration transform vs keygeneration function The transform is more obvious because it is an object in the Dataflow. The function works for every row it encounters, while the transform will only generate a new key value for insert rows.
- Dec 08, 2016 Merge Transformation is used to combine the multiple input data sets into a single output data set. It is equivalent to SQL UNION ALL statement. In order to eliminate duplicate records from output dataset basically to attain UNION operation, add a.
- Mar 01, 2012 The only thing to watchout is, if using the row-by-row setting of the Transform, the compare table has to have an index on the logical(!!) primary key - CUSTOMERID in this example. Now the Key Generation Transform gets insert and update rows but will overwrite the KEYID column only for rows with OP code of insert - rows that do not have a KEYID yet.
Sap Bods Key Generation
Vast is an Ocean,So is vast the World of Knowledge. With my diving suit packed, loaded with imaginative visions, and lots of curiosity, started diving deep into the world of BODS.Lots of work is going on. Got attracted towards the “Key_Generation” transform and was fascinated at its features.Now it was time for me to fuse and adapt myself into its world.
THE KEY_GENERATION TRANSFORM:-
This transform is categorized under the “Data Integrator Transforms”. This generates new keys for source data, starting from a value based on existing keys in the table we specify.
If needed to generate Artificial keys in a table, the Key_Generation transform looks up the maximum existing key value from a table and uses it as the starting value to generate new keys.
Key Generator
The transform expects the generated key column to be part of the input schema.
STEPS TO USE KEY GENERATION TRANSFORM:-
Scenario:- Here the target data source for which the keys is needed to be added, have certain newly added rows without a Customer_ID. This could be easily understood in the following snap:-
Our aim here is to automatically generate the keys(Customer_ID) in this case , for the newly inserted records which have no Customer_Id. Accordingly we have taken the following as our input (the modified data without Customer_ID)
Faststone capture key generator 8.9. INPUT DATA (to be staged in the db):-
TARGET TABLE(which contains the data initially contained in the source table before the entry of new records in the database):-
THE GENERATED DATA FLOW:-
/bitdefender-internet-security-2012-key-generator.html. CONTENT OF SOURCE DATA:- (containing the modified entry alone)
CONTENT OF QUERY_TRANSFORM:-
CONTENT OF THE KEY_GENERATION TRANSFORM:-
THE CONTENTS OF THE TARGET TABLE PRIOR JOB EXECUTION:-
The JOB_EXECUTION:-
THE OUTPUT AFTER THE JOB EXECUTION:-
We can now see from the output how Keys have been generated automatically to those records which did not have the Customer_ID initially.
Key Generation In Bods
I explored this little process of the Key_Generation transform, and it seems a savior at times when huge amount of data have the missing entries(wrt to the keys or any sequential column fields).
