SOLVED: Unknown type '246 in column 2 of 3 in binary-encoded result set

Today at our firm was problem like as "Unknown type '246 in column 2 of 3 in binary-encoded result set" when selected table has column as decimal(10, 2) type. This errors cause because we use old version of mysql jdbc driver. Solution for this problem is:

1. Download new version of driver
2. Convert double column to char on selection.

   SELECT CAST(your_column AS char(15)) your_column FROM your_table;

   So in this case on java side u can get it as Double again.

That is all u need know to solve this problem :))
