First of all, my knowledge about SSIS is... equal zero!

If you want to insert values (...)starting from 000001 and increment continuously for each row(...), it's not so simple! Why? 000001 is not a numeric value, it's a text!

The below example shows how to add/insert 1K records.

SQL

DECLARE @sNum NVARCHAR(6)
DECLARE @iNum INT
DECLARE @iCount INT
DECLARE @iCounter INT

-- add 1000 rows, starting from 1
SET @iNum = 1 
SET @iCount = 1000
SET @iCounter = 1
WHILE (@iCounter <= @iCount)
BEGIN
	SET @sNum = '000000'
	SET @sNum = SUBSTRING(@sNum, LEN(@sNum) - LEN(CONVERT(VARCHAR(6), @iNum))+1, LEN(CONVERT(VARCHAR(6), @iNum))) + CONVERT(VARCHAR(6), @iNum)
	INSERT INTO [YourTable] ([YourField]) VALUES(@sNum)
	SET @iNum = @iNum + 1
	SET @iCounter = @iCounter + 1
END

Results:

000001<br />
000002<br />
...<br />
001000
