I have got a problem handling some records which have a couple of columns (A, B, C) with Null value representing with the ? sign. Also, those records have another column (D) which is totally empty. I want to exclude those records with empty D column but don't know what criteria to put in to...
Could anyone show me how to import data from a tab-delimited file (txt or csv) into a new Teradata table without having to write the CREATE TABLE statement again, given the column names defined in the source txt file? Is there a import function similar to the DTS in SQL Server?
