Oracle JDBC Load Fails with Timestamp Partitioning (lowerBound/upperBound)

[pavlosskev]

Hi everyone,

I'm trying to read data from an Oracle database into Databricks using JDBC with timestamp-based partitioning. However, it seems that the partitioning doesn't work as expected when I specify lowerBound and upperBound using timestamp strings (for Azure SQL this works fine).

Here's a simplified version of my code:

df = (
    spark.read.format("jdbc")
    .option("url", jdbcUrl)
    .option("dbtable", query)
    .options(**connectionProperties)
    .option("partitionColumn", "TIJDSTEMPEL")
    .option("lowerBound", "2025-07-04 17:00:00")
    .option("upperBound", "2025-07-14 16:00:00")
    .option("numPartitions", 4)
    .load()
)

The TIJDSTEMPEL column is a TIMESTAMP in Oracle. If I don't use partitioning, the query works fine. But as soon as I add the .option("partitionColumn", ...) and bounds, it returns the error:  ORA-01861: literal does not match format string

Has anyone successfully loaded Oracle data using TIMESTAMP column for partitioning? Any advice or working examples would be appreciated!

Thanks in advance!

@pavlosskev Could you try adding the following option as well to your read?

.option("sessionInitStatement", "ALTER SESSION SET NLS_TIMESTAMP_FORMAT = 'YYYY-MM-DD HH24:MI:SS'")

df = (
    spark.read.format("jdbc")
    .option("url", jdbcUrl)
    .option("dbtable", query)
    .options(**connectionProperties)
    .option("sessionInitStatement", "ALTER SESSION SET NLS_TIMESTAMP_FORMAT = 'YYYY-MM-DD HH24:MI:SS'") 
    .option("partitionColumn", "TIJDSTEMPEL")
    .option("lowerBound", "2025-07-04 17:00:00")
    .option("upperBound", "2025-07-14 16:00:00")
    .option("numPartitions", 4)
    .load()
)
