Writing SQL Query

I am connecting to a historian and I can only connect to it with OLE DB and it only allows SET and SELECT statements in SQL queries. It follows the SQL-92 convention.

So I want to query one column in the historian and produce a few columns based on some kind of sorting.

In that one column in the historian the data looks like this:

BOAT_PART_A
CAR_PART_B
BOAT_PART_B
CAR_PART_A
PLANE_PART_B
PLANE_PART_A

I then want to sort that data into three columns looking like so:

column A| column B| column C
CAR_PART_A BOAT_PART_A PLANE_PART_A
CAR_PART_B BOAT_PART_B PLANE_PART_B

and i did not understand the format of your data
each row in
BOAT_PART_A
CAR_PART_B
BOAT_PART_B
CAR_PART_A
PLANE_PART_B
PLANE_PART_A

is one row (that is do you have 6 rows here) or is it only one row all togheter

"historian" is the name of the table.

These are six rows in one column. You can assume that the table has only one column.
Basically what I want to do is convert this one column table into three column table in which the first column has all the data that starts with "BOAT_PART", second has "CAR_PART" and so on in the formate specified above.
There are following restriction:
1) Only SELECT and UPDATE statements are available
2) No temporary table can be used

ok
got you
in order to "create" 3 column from only one column you have to join the table  to itself twice, so the select that will create the table for you is
select
from historian t1, historian t2, historian t3
where t1.col like 'BOAT_CART%'
and  t2.col like 'CAR_PART%'
and t3.col like 'PLANE_PART%'
and right(t1.col,1) = right(t2.col,1)
and right(t2.col,1) = right(t3.col,1)

this will produce the table
you won't be able to update though, and i don't think you will be able to implement a solution that will allow an update
