I have a table as per below detail:-

CREATE TABLE ITEM_DIM
(DOCKET_NO VARCHAR(9),DOC_DT DATETIME,GL_CODE VARCHAR(10),ITEM_CD VARCHAR(15),
ITEM_DIMENSION VARCHAR(100),LOT_NOS VARCHAR(15),
QTY1 DECIMAL(14,6),QTY2 DECIMAL(14,6),QTY3 DECIMAL(14,6),QTY4 DECIMAL(14,6),QTY5 DECIMAL(14,6),
QTY6 DECIMAL(14,6),QTY7 DECIMAL(14,6),QTY8 DECIMAL(14,6),QTY9 DECIMAL(14,6),QTY10 DECIMAL(14,6)
,QTY11 DECIMAL(14,6),QTY12 DECIMAL(14,6),QTY14 DECIMAL(14,6),QTY15 DECIMAL(14,6),QTY16 DECIMAL(14,6))

inserted statement to insert data into table :-

INSERT INTO ITEM_DIM (DOCKET_NO,DOC_DT,GL_CODE ,ITEM_CD ,ITEM_DIMENSION ,LOT_NOS ,QTY1,QTY2,QTY3,QTY4,QTY5,QTY6,QTY7,QTY8) values

SELECT DOC_DT,PARTY_CD,ITEM_CD,LOT_NOS,INNER_DIA,THK FROM
(
SELECT DOC_DT,GL_CODE PARTY_CD,ITEM_CD,LOT_NOS,QTY1 INNER_DIA,0 THK FROM ITEM_DIM
WHERE ITEM_DIMENSION IN ('INNER DIA','INNER DIA 1')
UNION ALL
SELECT DOC_DT,GL_CODE PARTY_CD,ITEM_CD,LOT_NOS,QTY2 INNER_DIA,0 THK FROM ITEM_DIM
WHERE ITEM_DIMENSION IN ('INNER DIA','INNER DIA 1')
UNION ALL
SELECT DOC_DT,GL_CODE PARTY_CD,ITEM_CD,LOT_NOS,QTY3 INNER_DIA,0 THK FROM ITEM_DIM
WHERE ITEM_DIMENSION IN ('INNER DIA','INNER DIA 1')
UNION ALL
