Redshift Table Creation Scripts

select * from admin.v_generate_tbl_ddl where schemaname ='nameofschema' and tablename='nameoftable';

If the view v_generate_tbl_ddl is not in your admin schema, you can create it using below sql provided by the AWS Redshift team.

Firstly, type in this query which is shown below:

GO

Secondly, on the same machine execute this query:

EXEC sp_help_revlogin

Thirdly, copy the output and on another instance paste the

 output and all the users will be added.

Create Login if not exists.

SSRS Date Format using Expression

Any column display with value of 1/1/1900 12:00:00 AM even after the SQL Server Query output is correct, you need to follow the below IIF statement in expression of SSRS

SELECT [ReviewDate] AS  [ReviewDate] from Tablename.

Review Date is datetime.

Solution to SSRS is: Editing the value like below. If the value is Null or Empty, the below one is a good one for that issue

=IIF(Fields!ReviewDate.Value="1/1/1900 12:00:00 AM","",Format(Fields!ReviewDate.Value,"dd-MM-yyyy"))

In SQL Server, you can use the query

SELECT isnull(Convert(Varchar(10),[ReviewDate],105),'') AS  [ReviewDate] from TableName

However, although the above SQL display is correct, it won't help in SSRS. Therefore, one should follow the above IIF statments, that is

=IIF(Fields!ReviewDate.Value="1/1/1900 12:00:00 AM","",Format(Fields!ReviewDate.Value,"dd-MM-yyyy"))

Normal Date Format formula is as per below:

=Format(CDate(Fields!ReviewDate.Value), "dd-MM-yyyy") -- Works well
