I have an SQL query like below

select * from table1 where test in ('','123', '345');


How do I create preparedStatement for this, the issue is the
number of values in <ed> IN predicate can be different;
for example, the query can be as below depending on what user
selects on screen

select * from table1 where test in ('','123', '345');

or

select * from table1 where test in ('','123', '345', '1233');

or

select * from table1 where test in ('','123');


FWiW the question seems general for SQL rather than specific to any language support of the SQL; i.e. not specific to JAVA. Presumably that is why the subject is noted as OT. Rather than posting an Off Topic discussion to a group, why not just post the technical question to the Midrange-L which is not specific to a language or utility\application? Regardless, ...

If there is a limit to the number of values selected on the screen, e.g. five values, then the following should be possible:

WHERE test IN (?, ?, ?, ?, ?)

Any parameter markers that are not given a value from the screen can be set to the same value as the first [possibly the only] value from the screen. As such, the first example would translate into:

WHERE test IN ('', '123', '345', '', '');
