| I'm having problem finding solution for constraint:Table has 2 columns, condition and date. Condition is binary and, if it is 1, you have to enter the date. If ii is 0, you can't enter the date.How could I solve this using constraints?Thanks! |

| do you mean to say that if condition is 0,date should be null or is it that if its 0 date value shouldnt be allowed to update? if its latter, then what you need is an instead of update trigger. |
