SQL CASE ANOTHER COLUMN OF ANOTHER ROW

Dears

Im trying to case a column to use the sum of M_DR + M_CR as the CLS_BAL. E,g if the ID is 192000801 then it should have the sum of M_DR and M_CR of ID 1920008      as its CLS_BAL as I have made in bold below.

Attach is a sample of the data I am working with.

SHEET        CAT        H_ID      ID        CHRT_ID        OPN_BAL        M_DR        M_CR        CLS_BAL
BALANCE      ASSETS      10122      1920008        1920008        0.00        3000.00      0.00        0.00
BALANCE      ASSETS      10125      192000801      192000801      0.00 0.00        0.00        3000.00
BALANCE      ASSETS      10117      1930002        1930002        20847369.45        0.00        403436.43 21250805.88
BALANCE      ASSETS      10125      193000201      193000201      0.00        0.00        0.00        0.00

you want M_DR + M_CR as the CLS_BA .. rite ?

try this

Select SHEET, CAT, H_ID, ID, CHRT_ID, OPN_BAL, M_DR, M_CR, (M_DR + M_CR) as n_CLS_BAL

from tablename

Yes, but I want ID 192000801 to have (M_DR + M_CR) of ID 1920008

This relies on having only one matching row for each (shortened) ID:

Select SHEET, CAT, H_ID,  a.ID,  CHRT_ID, OPN_BAL, M_DR, M_CR,  n_CLS_BAL
from tbl a
left join (select ID, M_DR + M_CR as n_CLS_BAL from tbl) b
on left(a.ID, 7) = b.ID

I was looking forward for something similar to this(syntax not correct though):

CASE
WHEN CHRT_ID ='193000201' THEN (RP_M_DR + RP_M_CR WHERE CHRT_ID ='1930002')

Thanks Qlemo, I had this in mind, but had difficulty referencing 'tbl' because it my tbl is a derived table from a subquery.

The ID's I also want to have fixed are just 3 in number, and wont change.

To avoid line wrap, embed your data inside the Code brackets, it will be far easier to read:

SHEET        CAT         H_ID       ID            CHRT_ID          OPN_BAL        M_DR          M_CR          CLS_BAL
BALANCE      ASSETS      10122      1920008       1920008             0.00       3000.00         0.00            0.00
BALANCE      ASSETS      10125      192000801     192000801           0.00          0.00         0.00         3000.00
BALANCE      ASSETS      10117      1930002       1930002      20847369.45          0.00    403436.43     21250805.88
BALANCE      ASSETS      10125      193000201     193000201           0.00          0.00         0.00            0.00

If you generate your subquery data as in my first example, or with a CTE, you should have no difficulties to access the results as in my second example.
