LAS 6.3 : Adding scattered data (from a database)

The test database is named testDB and has a table testTable.

The content of testTable is shown below:

mysql> select * from testTable;

+--------+--------+---------+------------------+---------+

| id | lo | la | time | sst |

+--------+--------+---------+------------------+---------+

| 1 | 10 | 15 | 1999-01-01 | 47 |

| 2 | 20 | 25 | 1999-02-01 | 57 |

| 3 | 40 | 45 | 1999-03-01 | 67 |

| 4 | 75 | 80 | 1999-04-01 | 77 |

| 5 | 80 | 90 | 1999-05-01 | 59 |

+--------+--------+---------+------------------+---------+

But when I tried to access database through LAS ui, following error message occured:

LAS Error

The following error message was received from LAS:
