and following errors in meta.log (oc logs syndesis-meta-… > meta.log) meta.log

server.log and db.log looks OK.

This problem is somehow related only to CONTACT db table in the FINISH connection. (not with TODO table. e.g. if in step 5 we specify eg.

INSERT INTO TODO(task, completed) VALUES(:#task, 0), 

this misbehavior is not seen.)

Expected behavior

API Endpoints and Schemas

POST https://syndesis.192.168.99.100.nip.io/api/v1/connections/5/actions/sql-connector Request Body: {“query”:“INSERT INTO CONTACT (first_name) values (:#fn)”}

response: sql-connector.json.txt

Tasks involved / Steps to Reproduce

1. Select Create Integration.
2. Select start connection PostgresDB.
3. Select action “Periodic SQL invocation” and specify query “SELECT * FROM TODO”
4. Select finish connection PostgresDB.
5. Select action “Ivoke SQL”. and specify query related to CONTACT table “INSERT INTO CONTACT (first_name) values (:#fn)”
6. add datamapper step

[KurtStam]

It looks like it’s related to ‘values’ being lowercase in:

INSERT INTO CONTACT (first_name) values (:#fn)

I will add a unit-test and fix for it.

Thanks @Stefan365 for double checking I’ll have a look.
