How to hide the Repeated record in SQL - mysql

Question

Using this query:
SELECT
linerbltbl.billofladingid,
linerbltbl.grossweighttotal,
linerb‌​ltbl.netweighttotal,
linerblwisecontainerdetailstbl.containertype,
linerblwisecont‌​ainerdetailstbl.cont‌​ainernumber,
linerblwisecontainerdetailstbl.sealnumber,
linerblwisecontain‌​erdetailstbl.princip‌​lecharge
FROM linerbltbl,
linerblwisecontainerdetailstbl
WHERE linerbltbl.shippername IS NOT NULL
AND linerbltbl.billofladingid =
linerblwisecontainerdetailstbl.bil‌​lofladingid
See this image. It shows what my output IS and what I would like it to be.
You will note that the repeated data is blanked out. Is there a way to do this in my query?

Answer 1

First of all, I think you are going about this wrong. While you CAN do this from within the query itself (see this page) you are probably better off doing it in whatever is consuming the output. For example, if you are taking this data and pasting it into MS Excel, you could check out this post which does is via conditional formatting. If you are consuming it from inside code, you can add logic to handle it there (since I don't know what you are going to do with it, it's hard to add any examples).
But, if you insist on doing it from within SQL it's going to be something to this effect (borrowing from the linked example):
;with t as
(SELECT
linerbltbl.billofladingid,
linerbltbl.grossweighttotal,
linerb‌​ltbl.netweighttotal,
linerblwisecontainerdetailstbl.containertype,
linerblwisecont‌​ainerdetailstbl.cont‌​ainernumber,
linerblwisecontainerdetailstbl.sealnumber,
linerblwisecontain‌​erdetailstbl.princip‌​lecharge
FROM linerbltbl,
linerblwisecontainerdetailstbl
WHERE linerbltbl.shippername IS NOT NULL
AND linerbltbl.billofladingid =
linerblwisecontainerdetailstbl.bil‌​lofladingid
)
SELECT
CASE WHEN RR = 1 THEN billofladingid ELSE '' END BillOfLadingID,
CASE WHEN RR = 1 THEN grossweighttotal ELSE '' END GrossWeight,
CASE WHEN RR = 1 THEN netweighttotal ELSE '' END NetWeight,
containertype,
cont‌​ainernumber,
sealnumber,
princip‌​lecharge
FROM
(SELECT (ROW_NUMBER() OVER(PARTITION BY billofladingid ORDER BY billofladingid, grossweighttotal)) [RR], *
FROM t) SUBQUERY1
