  • sql - MINUS Operator in oracle - Stack Overflow
    MINUS takes the first result set, and removes any that exist in the second result set; it also removes any duplicates In your example, tableA has 389 rows, and tableB has 217 rows; your INTERSECT shows there are no rows in common, which means tableA MINUS tableB is 389 rows (i e all of them)
  • Pra que serve e como funciona o comando MINUS no oracle
    O comando MINUS do Oracle tem o sentido de "exceção" É utilizado normalmente para excluir dados que retornem numa consulta Não confunda com excluir dados como o DELETE É algo bem diferente Tomando o seu código como exemplo, SELECT b COD_CARRO, b NOM_CARRO FROM CARROS b MINUS SELECT a COD_CARRO FROM VEICULOS a;
  • optimization - optimize query with minus oracle - Stack Overflow
    A MINUS also requires that both queries have the same number of columns, and that each column has the same data type as the corresponding column in the other query (or one convertible to the same type) A MINUS will return all rows from the first query where there is not an exact match column for column with the second query
  • Subtracting Dates in Oracle - Number or Interval Datatype?
    Ok, I don't normally answer my own questions but after a bit of tinkering, I have figured out definitively how Oracle stores the result of a DATE subtraction When you subtract 2 dates, the value is not a NUMBER datatype (as the Oracle 11 2 SQL Reference manual would have you believe)
  • Oracle MINUS both ways (get difference between select)
    MINUS All distinct rows selected by the first query but not the second you could use intersect but the number of select are pratically the same (select foo from foobar where bar = 1 union select foo from foobar where bar = 2) minus (select foo from foobar where bar = 1 intesect select foo from foobar where bar = 2)
  • Minus vs Except Difference in ORACLE SQL Server
    MINUS is a SQL set operation that selects elements from the first table and then removes rows that are also returned by the second SELECT statement in Oracle And in SQL Server, we can use EXCEPT to do same thing While migrating my project from oracle to SQL Server, I noticed a difference
  • sql - Calculating difference between two timestamps in Oracle in . . .
    An Oracle TIMESTAMP has subsecond precision-- generally either millisecond or microsecond depending on the platform – Justin Cave Commented Jul 23, 2012 at 18:10
  • Prevent Oracle minus statement from removing duplicates
    SELECT TEST, row_number() OVER (PARTITION BY TEST ORDER BY TEST) FROM TEST1 MINUS SELECT TEST, row_number() OVER (PARTITION BY TEST ORDER BY TEST) FROM TEST2 This would be MINUS with each duplicate treated as a distinct entry Note in the example below, if TEST1 has two 'C' values and TEST2 has only one, you get one in the output
