Inserting Array list into HANA database

Try using below code:

Example

Integer[][] myarray ={ {1}, {1,2}, {1,2,3,4,5} };
   String test = "Insert Arrays";
   stopWatch.start(test);
   myDBconn.setAutoCommit(false);
   Statement stmt = myDBconn.createStatement();
   stmt = myDBconn.createStatement();
   stmt.execute("TRUNCATE TABLE Schema.Table1");
   // Running a loop over our array of arrays
   for (int i = 0 ; i < (myarray.length); i++) {
      int curr_length = myarray[i].length;
      String arrayFunction = "ARRAY (";
      for (int j = 0; j < (curr_length); j++){
         arrayFunction = arrayFunction.concat(myarr[i][j].toString()) ;
         // add comma if this is not the last element
         if (j < (curr_length - 1)){
            arrayFunction = arrayFunction.concat(", ") ;
         }
      }
     arrayFunction = arrayFunction + ")" ;
     // You can see arrayFunction as it look like below
     // ARRAY ( ..., .... ,... )
     String insCMD = "INSERT INTO Table1 (id, Value) "
        + " VALUES (" + i + ", "
        + arrayFunction
        + " ) ";
     System.out.println(insCMD);
     int affectedRows = stmt.executeUpdate(insCMD);
     System.out.println("Loop round " + i
        + ", last affected row count " + affectedRows);
     }
     myDBconn.commit();
     stmt.close();
     stmt = null;

Output

Output of above program when I run Select statement:

ID Value
0 1
1 1, 2
2 1, 2, 3, 4, 5
