tMap with dynamic sql lookup

Anonymous — Sat, 16 Nov 2024 14:01:47 GMT

Hi,
in tMap it is not possible to lookup additional information with a dynamic sql query.
My tSybaseInput_1 is only fired at startup of my job, but i want to query the database for each row.
In tJavaRow_1 i also set the contextvar "currentAZ", which is used by tSybaseInput_1
Do you have a suitable solution, i don't want to fetch the whole table in tSybaseInput_1.

Query in t_SybaseInput_1:

"SELECT
AZ
FROM FCAdmin.Akte
WHERE AZ = '"+context.currentAZ+"'"

Thanks and Regards
Sebastian

You can so a dynamic sql lookup into the TOS 3.1.0 M2 release.
See also this page, there is a screenshot on this subject (dynamic lookup, not specifically with SQL):

Hi,
Can someone tell me how to perform dynamic look up in Talend?
please see below an example problem that requires dynamic lookup.
example:
source file has the following data
employee_name|employee_Id
===========================
Ted | 100
Mary | 200
Ted 100
target table structure:
surrogate_Id | Employee_Name | Employee_Id
=========================================

after load the target table should look as shown below
surrogate_Id | Employee_Name | Employee_Id
=======================================
1 | Ted | 100
2 | Mary | 200

currently when I do a look up and insert data, employee Ted is getting inserted twice. This might be because the commit happens at the end of the job.
How can I include records that were inserted as part of the current transaction but not commited??
Thanks in advance
