This line solved my same problem in postgresql   SELECT DATE PART  year   column name  date  from tableName    If you want month  then simply replacing year with month solves that as well and likewise

Choose one from  where  my date is a string input parameter of yyyy-MM-dd format   SELECT EXTRACT YEAR FROM CAST  my date AS DATE      or  SELECT DATE PART  year   CAST  my date AS DATE      Better use CAST than    as there may be conflicts with input parameters
