             Summary: JDBCUpsertOutputFormat does not set bind parameter 
keyFields in updateStaement
                 Key: FLINK-15728
                 URL: https://issues.apache.org/jira/browse/FLINK-15728
             Project: Flink
          Issue Type: Bug
          Components: Connectors / JDBC
    Affects Versions: 1.9.1
            Reporter: Bhagavan


When using JDBCUpsertOutputFormat custom dialect e.g. H2/Oracle which uses 
UpsertWriterUsingInsertUpdateStatement, code fails with below error.
{code:java}
Caused by: org.h2.jdbc.JdbcSQLDataException: Parameter "#6" is not set 
[90012-200]Caused by: org.h2.jdbc.JdbcSQLDataException: Parameter "#6" is not

 {code}
This is due UpsertWriterUsingInsertUpdateStatement#processOneRowInBatch
 does not set all bind paramters in case of Update.

This bug does get surfaced while using Derby DB. 
 In JDBCUpsertOutputFormatTest if we replace Derby with H2 we can reproduce the 
bug.

The fix is trivial. Happy to raise PR.
{code:java}
//for update case replace below
setRecordToStatement(updateStatement, fieldTypes, row); 
//with
setRecordToStatement(updateStatement, fieldTypes + pkTypes, row  + pkRow);
//NOTE:  as prepared updateStatement contains addition where clause we need 
pass additional bind values and its sql Types
