[jira] [Commented] (HIVE-22520) MS-SQL server: Load partition throws error in TxnHandler (ACID dataset)

["Gopal Vijayaraghavan (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-22520?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16978961#comment-16978961 ] 

Gopal Vijayaraghavan commented on HIVE-22520:
---------------------------------------------

https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/tools/SQLGenerator.java#L161

There's a loop here to avoid this particular bug.

{code}
        insertPreparedStmts = sqlGenerator.createInsertValuesPreparedStmt(dbConn,
            "TXN_COMPONENTS (tc_txnid, tc_database, tc_table, tc_partition, tc_operation_type, tc_writeid)",
                rows, paramsList);
        for(PreparedStatement pst : insertPreparedStmts) {
          modCount = pst.executeUpdate();
        }
{code}
