load mysql table with binary field

[Anonymous]

Hi, all,

May I know how to correctly load mysql table with binary column?

I need to use a table from a database implemented by a college, and found that one column is binary data.

After a normal "LOAD", this binary column is empty for some rows. Have no idea why. Dose any one knows about this?

Though I solved the problem as the reply below, but I do not understand why only some rows get "empty" data. It seems not null, as I use isNull() condition to check the value, it still get an empty column.

Thanks very much

Hi, all,

I solved the problem by first load binary in mysql load using HEX() function like this:

LOAD ...;

SQL SELECT

     HEX(Id) as Id,

     Name,

FROM table01;
