There are many solutions to this
a) Redesign your Database
b) This field that you want to act like 2D array must be a unique key (autoInc).
Add a second detail table (2D array Values).
In the detail table there are 3 keys
1) The foreign key from the 1st table
2) One Sequence field for the first dim (autoinc)
3) One Sequence field for the second dim (autoinc)
and one more field for your data.
now you can access the array like this
where Foreignkey = Foreignkey
and FirstDim = 1
and SecondDim = 5
and you got the data from the array[1, 5]
i hope you help with this ...
