impala jdbc not support UPSERT preparestatement (KUDU)

JDBC version is impala_jdbc_2.5.37.1057

code is like below:

conn.setAutoCommit(false);
PreparedStatement pstmt = conn.prepareStatement(sqlStatement);
for (ArrayList<String> ss : list) {
    for (int i=0;i<types.length;i++) {
        String s = "NULL";
        if (i < ss.size()) s = ss.get(i);
        setDataValue(i+1, pstmt, types[i], s);
    }
    pstmt.addBatch();
}
pstmt.executeBatch();
pstmt.close();
conn.setAutoCommit(true);


when the sqlStatement is using INSERT it's ok, but when using UPSERT, it report below exceptions

Exception in thread "main" java.sql.SQLException: [Simba][ImpalaJDBCDriver](500057) Multi-batch parameter values not supported for this query type.

Hi,

Two questions:

1) What query are you trying to execute?

2) Can you try adding the "UseNativeQuery=1" option to the jdbc driver connection string? (see http://www.cloudera.com/documentation/other/connectors/impala-jdbc/latest/Cloudera-JDBC-Driver-for-I... for details)

Thanks

hello Matt Jacobs thanks for response, our sqlstatement is like below insert into tablename (id,col1,col2) values(?,?,?) or upsert into tablename (id,col1,col2) values(?,?,?) when using insert is ok, but upsert report exception. for your advise we now trying, late will give you the result thanks

we try "UseNativeQuery=1" option to the jdbc driver connection string, the result is same as before.

Hello, i have the same result 😞 have you find a solution ?

[#6]

I have the same problem, is this a bug?

[#7]

As upsert is not SQL-92 syntax, the Impala JDBC driver does not currently support it.   However, we are currently testing a newer version of JDBC driver and hope to support upsert in the near future.  For the time being, please break these statements into a combination of insert and update statements.
