Ramesh Reddy commented on TEIID-5397:
-------------------------------------
I do not follow what you are suggesting, do you have links from Postgresql how it does
it?
RETURN_GENERATED_KEYS not working
---------------------------------
Key: TEIID-5397
URL:
https://issues.jboss.org/browse/TEIID-5397
Project: Teiid
Issue Type: Bug
Affects Versions: 10.2.1
Reporter: Lukáš Svačina
Assignee: Steven Hawkins
*+VDB:+*
{code}
<vdb name="_GENERATED_form_shoes" version="2">
<model name="_INTERNAL_internalModel" type="PHYSICAL">
<source name="internal_postgresql"
translator-name="postgresql"
connection-jndi-name="java:/internal"/>
</model>
<model name="GEN_view" type="VIRTUAL">
<metadata type="DDL">
<![CDATA[ CREATE VIEW "_view_workflow_data" OPTIONS (UPDATABLE
'true')
AS SELECT
"public"."form_shoes_2"."size" AS "size",
"public"."form_shoes_2"."model" AS "model",
"public"."form_shoes_2"."id" AS
"id" FROM "public"."form_shoes_2" ]]>
</metadata>
</model>
</vdb>
{code}
*+TABLE:+*
name: form_shoes_2
columns: id (SERIAL) | size (INTEGER *NULLABLE*) | model (VARCHAR *NULLABLE*)
*+PROBLEM:+*
Connected into VDB using JDBC like:
{code:java}
final PreparedStatement statement = c.prepareStatement(...INSERT...,
Statement.RETURN_GENERATED_KEYS);
statement.executeUpdate();
final ResultSet generatedKeys = statement.getGeneratedKeys();
{code}
*generatedKeys is empty if:*
# INSERT INTO "form_shoes_2" ( "model" ) VALUES ( 'adidas x1'
) ...... e.g. not all columns are enumerated ... if so, you can provide NULL values to
optional columns and generated keys WORK!
# INSERT INTO "_view_workflow_data" (id, name, size) VALUES (42, 'adidas
x2', 12 ) ....... e.g. insering into view (1:1, no joins involved) even when all
columns ARE enumerated ... probably no way how to get generated keys here?
*+QUESTIONS:+*
# How to get last_insert_id() when inserting into foreign table/views (with/without
joins)?
# How to get updated rows (UPDATE ... RETURNING *)? At least primary keys of affected
rows?
Thanks for fixing/adding this functionality.
