I have to execute the following SQL... DELETE FROM EMPLOYEE_OBJECTIVE WHERE OBJECTIVE_ID NOT IN ( ?) The NOT IN clause may have many values, or it may have one like (2) or (2,6,9), but how do I use a PreparedStatement to set the values? I cant use multiple '?' because I dont know how many values might occure; it's dynamic. catch ya later, SAF
FYI.... I believe if you use a "not in" your indexes will not be used. Try checking your database's manual to see what it says. If you have a very large database, it may take a long time to execute. Dan
once you create a PreparedStatement you can't change it. So if you have the PreparedStatement of "SELECT * from emp where empid in (?)", you can only substitute one value for the ?. There is no way (as of jdbc 2.0) to substitute an array of values for a '?'. The only way you could work it would be to dynamically create the sql String for each query(pretty much like using a Statement). Probably not what you want to hear maybe you can make up the performance by batching the Statements?
