[jira] [Updated] (NIFI-5049) Fixhandling of Phonenix datetime
columns in QueryDatabaseTable and GenerateTableFetch
[ https://issues.apache.org/jira/browse/NIFI-5049?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

--------------------------------------
Affects Version/s: (was: 0.6.0)
1.5.0
Remaining Estimate: 24h
Original Estimate: 24h
Fix Version/s: (was: 1.2.0)
Description:
QueryDatabaseAdapter does not work against Phoenix DB if it should convert TIMESTAMP. The error is described below:
[https://stackoverflow.com/questions/45989678/convert-varchar-to-timestamp-in-hbase]
Basically, it's required to use TO_TIMESTAMP(MAX_COLUMN) to make it work.
See [https://lists.apache.org/thread.html/%3CCA+kiFscJE8AY+UxT_D_vSt4QgZF4jxWoVBOYnJgztt4dSbSXWQ@mail.gmail.com%3E]
was:
Due to default handling of Oracle columns returned as java.sql.Date types, the string literals used to compare against the column values must be in the same format as the NLS_DATE_FORMAT setting of the database (often YYYY-MM-DD).
I believe when "Oracle" is provided as the database type (formerly known as pre-processing strategy), Oracle's Datetime Functions (such as TO_DATE or TO_TIMESTAMP) could be leveraged to give more fine-grained maximum-value information.
