INSERT INTO table2

SELECT FDT1, TODT1 FROM table1

UNION ALL

SELECT FDT2, TODT2 FROM table1

Edit: corrected the code with comma's between the columns

INSERT INTO table2(frmdt,todt)

SELECT ca.frmdt,ca.todt

FROM table1 t

CROSS APPLY(SELECT FDT1, TODT1

UNION ALL

SELECT FDT2, TODT2

UNION ALL

SELECT FDT3, TODT3) ca(frmdt,todt)

INSERT INTO table2 SELECT FDT1 TODT1 FROM table1 UNION ALL
SELECT FDT2 TODT2 FROM table1

I think you might need to add a comma between the column names ...

You're absolutely right!! I have to look better if I copy/paste from a post.:hehe:

currently the data is inserted as

frmdate todate

2009-12-14 2009-12-28

2010-01-14 2010-01-28

2010-02-14 2010-02-28

instead of

frmdate todate

2009-12-14 2009-12-28

2009-12-29 2010-01-13

2010-01-14 2010-01-28

2010-01-29 2010-02-13

2010-02-14 2010-02-28

2010-03-01 2010-03-13

so used cross apply

its working fine

but with a issue in other fields which were taken i query

Remember, the output is only quaranteed in a specific order if you specify the ORDER BY in the query. How the data is phisically structured is not importand.

used INSERT INTO table2(frmdt,todt)

SELECT ca.frmdt,ca.todt

FROM table1 t

CROSS APPLY(SELECT FDT1, TODT1

UNION ALL

SELECT FDT2, TODT2

UNION ALL

SELECT FDT3, TODT3) ca(frmdt,todt)

the records are inserted as needed

thanks very for the same

but a slight issue with other fields that is being inserted

insert into table2(year,frmdt,todt,No,Consno)

SELECT t.YEAR,ca.frmdt,ca.todt @No,@Consno

FROM table1 t

CROSS APPLY(SELECT FDT1, TODT1

UNION ALL

SELECT FDT2, TODT2

UNION ALL

SELECT FDT3, TODT3) ca(frmdt,todt)

@No is a count taken from table3

if @no is 2

then the No column from the table2 will have data as

1

2

1

2

1

2

@Consno is a consecutive no

i am taking max(Consno)+1

so each record inserted will have

1

2

3

4....... consecutive nos

due to union all same no gets inserted in all records
