Hi Vijay,
Thanks for the reply
Let’s consider the scenario:
Source data type: ‘bit’
Destination data type: ‘bit’
QueryDatabaseTable=> UpdateRecord=> PutDatabaseRecord
QueryDatabaseTable:
Use Avro Logical Types
true
UpdateRecord:
Property
Value
Record Reader
AvroReader
Record Writer
AvroRecordSetWriter
Replacement Value Strategy
Record Path Value
/event_status
${event_status('true'):ifElse('1', '0')}
PutDatabaseRecord:
Record Reader
AvroReader
Thankyou
Deepanshu

Hi Deepanshu,
Can you please post the configuration of your UpdateRecord Processor, This is a
common use case and I believe this will benefit the community.
Thanks

Hii Dennis,
Thanks for the reply
I'll practice your suggested approach, however I've already done it by using
"UpdateRecord" processor.

Hello Deepanshu, I suggest you do the transformation in the query in the
"QueryDatabaseTable".
Using a combination of string functions substring() and or date functions until
you build the string you need on the MSSQL side.

Hi all,
I've created a simple data flow using "QueryDatabaseTable" and
"PutDatabaserRecord" which transfers the data from PostgreSQL DB to MSSQLServer
DB in which the datatype of datetime columns in source_db i.e., PostgreSQL
table is "timestamp without time zone", which is not compatible with
destination_db i.e., MSSQLServer.
This logs an error, what would be the correct method to transform the datatype
of the datetime columns while serving data from PostgreSQL to MSSQLServer.
Can anyone give me a tip how to transform the datatype of the such columns?
Thankyou in advance
Deepanshu
