Question

I want to Change Column data type from ‘VarChar’ to ‘DataType’ While inserting into another table from Source Table

I am able to do it in T-SQL

Declare @DateTime   As      DateTime
Declare @Date       As      NVARCHAR(20)

Set @Date = '120901'
Set @DateTime = CONVERT(Date,'20'+SUBSTRING(@Date,1,2)+'-'+SUBSTRING(@Date,3,2)+'-'+SUBSTRING(@Date,5,2))
Print @DateTime

How can i implement it in insert Statement

Insert Into AxisReportMain 
Select (Column1,Column2,Column3)
From ReportMain

Column2 Contains Date as ‘VarChar’. In AxisReportMain table Column2 DataType is “Date”

Answer 1

Try:

Insert Into AxisReportMain 
Select Column1,
       CONVERT(Date,'20'+SUBSTRING(Column2,1,2)+'-'+SUBSTRING(Column2,3,2)+'-'+SUBSTRING(Column2,5,2)) as Column2,
       Column3
From ReportMain
Where Column2 <> '000000'
