Relatively new to SSIS. I have a table that I've created in a data flow. Back out in the control flow, after the table has been created, I am trying to add two fields to this table which will hold the first and last name for a record since the name in this table has one field with both first and last names; I need to split them. All of the attempts below were done in an Execute Sql task.
First I tried to alter the table using an alter table command in the Execute Sql Task. I used this to add the two fields. Then I did an update statement with the split of the single name field into the new fields. I got an "SqlCommand.Prepare method requires all variable length parameters to have an explicitly set non-zero Size" error.
I then tried to save the table to a temp table (one pound sign) and then alter the temp table to have the two new fields. Then I tried to update the fields. I got the same "SqlCommand.Prepare" error as above.
Then I tried to create a view which selected all the fields from my table and, in the select statement for the view, I add two substring commands (as fields in the select) to split the single name, first extracting the first name and then extracting the second name. When I tried to create the view I was told that I had a syntax error near the word "view". I moved the create command to SSMS and it ran fine:
create view dbo.MyView
select *, SUBSTRING(EmployeeName, 1, CHARINDEX(' ', EmployeeName) - 1) as FirstName,
SUBSTRING(EmployeeName, CHARINDEX(' ', EmployeeName) + 1, LEN(EmployeeName)) as Lastname
Any Advice would be appreciated.

You can have computed column in your orginal table to do this job.

No need of all these.
if you know how it is going to come from the source then you can use a derived column in the DFT itself to get the two columns and load directly in one step.
