Create Table in SIC

I want to create a table and columns in SIC, but only the table name is being created. I want to know how to fix this problem. Below is my sample query and code.

Dim sql as new text.stringbuilder 

Sql.appendline(“Create Table employee(Name varchar(255) not null ,age int null);”

using dbconnap as dbconninfo = brapi.database.createexternaldbconninfo(si,”SICconnectionname”)

Brapi.database.executesql(dbconnapp,sql.tostring,true)

end using
