Select queries from two same structure tables

I have two tables identical in structure. Matter of fact one table was made from the other table. I have a column which has records that are not in the other table. The column is not id column. I would like to query this table to find out the records in this first table column that are not in the other table’s column(same column name). Basically I’m particulate about the records difference in that column only.


They both have same numbers of columns everything is the same no different. Same structure
