I think my [dbo].[simulateTable] is a mistake. Here the correction

/*
CREATE TABLE [dbo].[simulateTable](
[UniqueId] [int] IDENTITY(1,1) NOT NULL,
[cleanDate] [date] NULL
CONSTRAINT [PK_simulateTable] PRIMARY KEY CLUSTERED
(
[UniqueId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

*/

I need to Insert DataTable into simulateTable

(1) If DataTable(SCHL_SDTE)=0 and DataTable(LOAN_SDTE)=0, please insert [cleanDate] = NULL

(2) If DataTable(SCHL_SDTE) =0 and DataTable(LOAN_SDTE)!=0, please insert [cleanDate] = LOAN_SDTE

(3) If DataTable(LOAN_SDTE) =0, and DataTable(SCHL_SDTE)!=0, please insert [cleanDate] = SCHL_SDTE

(4) Else '20010101'

One more thing, how to insert my script properly using this Forum?

hi

here is the insert script .....Its giving errors

simulateTable column cleandate is DATE datatype ...

the data from main table is nvarchar
the data is like this ... 199906 this is only year and month
but cleandate DATE will expect day also

like this yyyymmdd where yyyy is year mm is month dd is day
example .. 20011019

what to do ???? put 01 as day for all data

Please click arrow to the left for Insert Script 
INSERT INTO [dbo].[simulateTable]
select 
CASE WHEN SCHL_SDTE= 0 and LOAN_SDTE = 0 then NULL
     WHEN SCHL_SDTE= 0 and LOAN_SDTE <> 0 then LOAN_SDTE
     WHEN SCHL_SDTE <> 0 and LOAN_SDTE = 0 then SCHL_SDTE 
     ELSE '20010101'
END as   [cleanDate]   
 FRoM [dbo].[DataTable]

If you click on this .. you can insert script properly

Here is your insert script

INSERT INTO [dbo].[simulateTable]
select 
CAST(
CASE WHEN SCHL_SDTE= 0 and LOAN_SDTE = 0 then NULL
     WHEN SCHL_SDTE= 0 and LOAN_SDTE <> 0 then LOAN_SDTE+'01'
     WHEN SCHL_SDTE <> 0 and LOAN_SDTE = 0 then SCHL_SDTE+'01' 
     ELSE '20010101'
END 
 as DATE) as   [cleanDate]   
 FRoM [dbo].[DataTable]

Data looks this this
