Oracle-SQL How to check dates before inserting

I have a simple insert statement like below

Insert into table_X (id, validFrom, validTo, someValue) VALUES(?,?,?,?);

where validFrom and validTo have a DATE type.

I want to insert records to table only if validFrom <= validTo. How can I add some condition checking to the SQL statement to do so? For now I’m doing the cheking with java and I want to do it in the sql query if possible.

EDIT

CREATE TABLE XYZ.TABLE_X 
(
  ID VARCHAR2(20 BYTE) NOT NULL , 
  VALIDFROM DATE NOT NULL , 
  VALIDTO DATE NOT NULL , 
  SOMEVALUE NUMBER(18, 0) NOT NULL , 
  CONSTRAINT TABLE_X_PK_N2 PRIMARY KEY 
  (
    ID , 
    VALIDFROM , 
    VALIDTO 
  )
  ENABLE
    CONSTRAINT  chk_table_x_valids
  (
    check(VALIDFROM <= VALIDTO )
  )
  ENABLE 
) 
ORGANIZATION INDEX 
LOGGING 
TABLESPACE XYZ 
...

Answer

You can add a check constraint:

alter table table_x add constraint chk_table_x_valids
    check (validFrom <= validTo);
