/**
*
* The AS400JDBCPreparedStatement class precompiles and stores an SQL statement.
* This provides the ability to efficiently run the statement multiple times. In
* addition, the statement may contain parameters. Use
* Connection.prepareStatement() to create new PreparedStatement objects.
*
*
* When setting input parameter values, the caller must specify types that are
* compatible with the defined SQL type of the input parameter. For example, if
* the input parameter has SQL type INTEGER, then the caller must call setInt()
* to set the IN parameter value. If arbitrary type conversions are required,
* then use setObject() with a target SQL type.
*
*
* For method that sets parameters, the application should not modify the
* parameter value until after the execute completes. Modifying a value between
* the setXXXX method and the execute method may result in unpredictable
* behavior.
**/
//
// Implementation notes:
//
// 1. See implementation note in AS400JDBCStatement.java about
// "private protected" methods.
//
// @F2A
// 2. We need to support ?=CALL statements. This is where the stored
// procedure returns an INTEGER value, and we treat it as the
// first parameter marker. The database and host server support
// the return value, but not as a parameter marker. Consequently,
// we have to fake it as the first parameter marker. If this appears,
// in the SQL statement, we strip it off and maintain this separately.
// Of course in that case we are always mapping the caller's parameter
// indices to the database's indices by decrementing by 1 as needed.
//
// @G8c
// 3. If there is a return value (ie ?=call xxxx) and the parameter
// index is 1 then return data for the return value (always an Integer).
// If not, decrement the parm index by one because internally the return
// value doesn't count. If there is no return value the count is correct
// so don't do anything in that case. Also, the database supports returning
// only integers so the metadata will always be an SQLInteger.

* Here is some information from service about this error.
*
* Yes, this trace code was added for a very ugly issue that showed up when
* customers started moving to Java 6. While trying to debug it, we found
* that the trace points ended up changing the behavior, so they were
* altered to trace to a dummy stream so that it would workaround Sun's bug.
* The CPS discussion item was 7LXN87.
*
* Here's the contents of our KB doc on the issue:
*
* Abstract A problem with the Sun HotSpot Server in the 1.6 JDK causes a
* variety of errors.
*
* Problem Summary: A problem was introduced into the version 1.6 JDK (Java
* Development Kit) and JRE (Java Runtime Environment) from Sun. The problem
* was introduced somewhere between update number 7 and update 12, which can
* cause a number of problems. Java version 1.6.0_7 works; however, version
* 1.6.0_12 produces the errors. The problem is specific to the HotSpot
* Server which is something like an optimizing compiler that is designed to
* provide the best operating speed for long-running applications similar to
* a Web server. The problem seems to always manifest itself by 'removing'
* parameters that had been bound to a statement. However, it is not
* possible to know that this has occurred without tracing the application.
* The outward symptoms are exceptions which will vary depending on what
* data is missing. The common errors that have been reported are as
* follows:
*
* SQLException: Descriptor index not valid CPD4374 - Field HVR000n and
* value N not compatible. <-- where N might a variety of different numbers
* SQL0302 - Conversion error on host variable or parameter *N. <-- where n
* might a variety of different numbers SQL0406 - Conversion error on
* assignment to column N. <-- where N might a variety of different numbers
*
* Resolution: The problem has been reported to Sun; however, at this time,
* no fix is available from them. We have found three ways to circumvent the
* problem:
*
* 1. Do not use JDK 1.6. 2. Use JVM property -client (this turns off
* performance code in Sun Hotspot). 3. Use JVM property
* -XX:CompileCommand=exclude
* ,com/ibm/as400/access/AS400JDBCPreparedStatement,commonExecuteBefore
* (more selectively, turn off part of Hotspot). 4. Use the latest version
* of jt400.jar (currently 6.6). Additional trace points that were added
* while searching for the source of the problem appear to have changed the
* Hotspot behavior.
*
*
*
* Update 2/24/2011. This was probably a problem with the buffer
* synchonization. Before JTOpen 7.1, a flag was set to indicate that a
* buffer was available. This flag did not utilize any synchronization. In
* JTOpen 7.1, the buffer management code was restructure to used
* synchronzation.
*
* A recreate for the original problem was found. It failed using the JTOpen
* 6.4 jar. We then used a jar with the change the set the default
* isjvm16SynchronizerStatic to false and set the default value of the
* property to false. The problem did not occur with the jar file.
