> DefaultJdbcPrepareStatementStrategy Iterator fails on null value inserts
> ------------------------------------------------------------------------
>
> Key: CAMEL-7803
> URL: https://issues.apache.org/jira/browse/CAMEL-7803
> Project: Camel
> Issue Type: Bug
> Components: camel-jdbc
> Affects Versions: 2.13.2
> Reporter: Nathan Wray
> Attachments: 7803-patch.txt

>
> The iterator returned by createPopulateIterator in
> DefaultJdbcPrepareStatementStrategy reports "hasNext() == false" when it
> encounters a map value of null. This happens when using the map header
> JDBC_PARAMETERS = "CamelJdbcParameters" to insert null values with a prepared
> statement. The Iterator ends prematurely when it reaches a parameter name
> with a null value.
> For example, passing in a map where the 3rd parameter of 19 has a value of
> null causes the following exception to be thrown:
> java.sql.SQLException: Number of parameters mismatch. Expected: 19, was:2
