-----------------------------------
[~rnsingh] Could you please provide more information? Which processor and what
flow did you use when the conversion mismatch happened? I'm trying to reproduce
the issue.
> DatabaseTableSchemaRegistry improvement to handle BIT/Boolean Type
> ---------------------------------------------------------------------

> Key: NIFI-12828
> URL: https://issues.apache.org/jira/browse/NIFI-12828
> Project: Apache NiFi
> Issue Type: Improvement
> Affects Versions: 1.25.0
> Reporter: RAVINARAYAN SINGH
> Assignee: RAVINARAYAN SINGH
> Priority: Major
> Labels: controller_services
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The issue stems from the fact that for the PostgreSQL JDBC driver, the
> Boolean type is mapped to {{{}java.sql.Types.BIT{}}}, not {{{}BOOLEAN{}}}.
> This causes the line {{columnResultSet.getInt("DATA_TYPE")}} to return -7,
> which corresponds to {{{}BIT{}}}, and
> {{DataTypeUtils.getDataTypeFromSQLTypeValue(dataType)}} to return
> {{{}null{}}}, leading to a null pointer exception.
