How to User IN Clause()

Question

Any body knows how to use IN in where clause?
I am passing values to ? like 2,3,1,0
like
String pos = "2,3,0,1";
String sql_1 = " update table tab1 set counter = -1 where counter in (?)"
                OracleCallableStatement updCounter1 = ( OracleCallableStatement ) fastConn.prepareCall( sql_1 );
                updCounter1.setString(1,pos);
                updCounter1.execute();
                updCounter1.close();
            } catch (Exception e){System.out.println(" counter not update <?>" +e);}

I use IN in where clauses all the time...
There are several things wrong with what you are trying to do...
1st: CallableStatement is used to call a stored procedure, not to execute a SQL statement. To execute a SQL statement, you use a Statement or a PreparedStatement; PreparedStatement is almost always better.

2nd: your SQL is wrong; either your table is named "tab1" and your SQL should be:
String sql_1 = " update tab1 set counter = -1 where counter in (?)"or your table is named either "TABLE" or "table (or maybe "Table" or taBle"), and "tab1" is a table alias that isn't doing anything effective in this statement, and your SQL should be: String sql_1 = " update \"TABLE\" set counter = -1 where counter in (?)"The quotes are necessary to use a reserved word as a table name, but they also make the name case-sensitive, so you have to exactly match the case of the name in the database; normally table names are case-insensitive in SQL statements.
3rd: when the string value "2,3,0,1" is bound to your SQL statement, it will be bound as an Oracle character datatype value; in other words, the SQL you will be attempting to execute is:
  update table tab1 set counter = -1 where counter in ('2,3,0,1')because counter is a numeric type and '2,3,0,1' is a character type, one or the other must be converted to perform the comparison; Oracle's rules in this case are that it will attempt to convert the character dataype to a single numeric value. The value '2,3,0,1' cannot be converted to any single number, so this SQl will generate an error,. Running the SQL in a command line tool such as SQL*Plus, we see:
SQL> update tab1 set counter = -1 where counter in ('2,3,0,1');
update tab1 set counter = -1 where counter in ('2,3,0,1')
ERROR at line 1:
ORA-01722: invalid numberIf you want a parameter to be treated as a number, you need to use an appropriate numeric data type and its corresponding setXXXX function, such as setInt, or setLong
(There is at least one popular database where, I am told, the driver doesn't really implement PreparedStatement but instead does string replacement within the SQL string, and what your are trying to do more or less works; Oracle is not like that at all).
4th: each parameter in a PreparedStatement or CallableStatement corresponds to exactly one data object; you cannot pass multiple numeric values and bind them to a sinle ? parameter in your SQL. In other words, this will work:
final string sql = "update table tab1 set counter = -1 where counter in (?,?,?,?)";
PreparedStatement updCounter1 = fastConn.prepareCall( sql );
updCounter1.setInt(1,2);
updCounter1.setInt(2,3);
updCounter1.setInt(3,0);
updCounter1.setInt(4,1);
updCounter1.execute();
updCounter1.close();There IS NO WAY to with Oracle to pass a single object/parameter and have it expand to a value list. (You can pass and receive arrays to stored procedures however; I've never done more than read the documentation about it though...)
5th: there is a 1,000 element limit to the number of values in a value list
6th: you don't normally need to cast your statement classes to the Oracle implementations, unless you'r going to use an Oracle-only feature of the implementation
Finally, Oracle has published quite a number of complete examples, you might take a look...
