What is the best approach using JDBC for parameterizing an IN clause? [duplicate]
There’s indeed no straightforward way to do this in JDBC. Some JDBC drivers seem to support PreparedStatement#setArray() on the IN clause. I am only not sure which ones that are. You could just use a helper method with String#join() and Collections#nCopies() to generate the placeholders for IN clause and another helper method to set all … Read more
JPA passing list to IN clause in named native query
The above accepted answer is not correct and led me off track for many days !! JPA and Hibernate both accept collections in native query using Query. You just need to do String nativeQuery = “Select * from A where name in :names”; //use (:names) for older versions of hibernate Query q = em.createNativeQuery(nativeQuery); q.setParameter(“names”, … Read more
SQL Server – In clause with a declared variable [duplicate]
This is an example where I use the table variable to list multiple values in an IN clause. The obvious reason is to be able to change the list of values only one place in a long procedure. To make it even more dynamic and alowing user input, I suggest declaring a varchar variable for … Read more

Empty IN clause parameter list in MySQL
If I have an application where I’m building the IN list dynamically, and it might end up empty, what I sometimes do is initialize the list with an impossible value and add to that. E.g. if it’s a list of usernames, I’ll start with an empty string, since that’s not a possible username. If it’s … Read more
PHP – Using PDO with IN clause array
PDO is not good with such things. You need to create a string with placeholders dynamically and insert it into the query, while binding array values the usual way. With positional placeholders it would be like this: $in = str_repeat(‘?,’, count($in_array) – 1) . ‘?’; $sql = “SELECT * FROM my_table WHERE my_value IN ($in)”; … Read more
IN Clause with NULL or IS NULL
An in statement will be parsed identically to field=val1 or field=val2 or field=val3. Putting a null in there will boil down to field=null which won’t work. (Comment by Marc B) I would do this for clairity SELECT * FROM tbl_name WHERE (id_field IN (‘value1’, ‘value2’, ‘value3’) OR id_field IS NULL)
