    After testing many suggestions I found that the following line of code does what I was looking for, i.e. it creates a table which is a copy of the old table, without copying any data from the old table (because of the Where 1 = 2 condition):

    sqlScript.AppendLine("Select * Into EBSRegister From XFW_PLP_Register Where 1 = 2")

    Yes you're on the right track though the new table won't have the indexes/constraints copied over.

    The "Create Table As Select (CTAS)" only works in Azure Synapse Analytics Platform System aka PDW. Also works in oracle but not in SQL Server.

You can try and create the table first and then do the insert like...

Using dbConn As DbConnInfoApp = BRApi.Database.CreateApplicationDbConnInfo(si)
'Create the table, only need this once
Dim sqlDM As String = "Create table EBSRegister ([RegisterID] varchar(255),[FirstName] varchar(255),[LastName] varchar(255))"
BRApi.Database.ExecuteActionQuery(dbConn, sqlDM,False, True)
'Insert the records into the new table
Dim sql As String = "insert into EBSRegister (RegisterID,FirstName,LastName) select RegisterID,FirstName,LastName from XFW_PLP_Register"
BRApi.Database.ExecuteActionQuery(dbConn, sql,False, True)
End Using

    Hi and thank you for your replies. Yes your solution would work, but the reason why I was trying to avoid using the "Create table <table name> (<column1>, <column2>, etc.)" command is that the table I want to recreate has around 50 columns, so I was looking for a way to copy the structure from an existing table
