/**
*
* An object that represents a precompiled SQL statement.
* <P>A SQL statement is precompiled and stored in a
* {@code PreparedStatement} object. This object can then be used to
* efficiently execute this statement multiple times.
*
* <P><B>Note:</B> The setter methods ({@code setShort}, {@code setString},
* and so on) for setting IN parameter values
* must specify types that are compatible with the defined SQL type of
* the input parameter. For instance, if the IN parameter has SQL type
* {@code INTEGER}, then the method {@code setInt} should be used.
*
* <p>If arbitrary parameter type conversions are required, the method
* {@code setObject} should be used with a target SQL type.
* <P>
* In the following example of setting a parameter, {@code con} represents
* an active connection:
* <pre>{@code
* BigDecimal sal = new BigDecimal("153833.00");
* PreparedStatement pstmt = con.prepareStatement("UPDATE EMPLOYEES
* SET SALARY = ? WHERE ID = ?");
* pstmt.setBigDecimal(1, sal);
* pstmt.setInt(2, 110592);
* }</pre>

* <div class="ReleaseSpecificDocumentation">
* <p class="rshead">HSQLDB-Specific Information:</p>
*
* From version 2.0, the implementation meets the JDBC specification
* requirement that any existing ResultSet is closed when execute() or
* executeQuery() methods are called. The connection property close_result=true
* is required for this behaviour.
* <p>
* JDBCPreparedStatement objects are backed by
* a true compiled parametric representation. Hence, there are now significant
* performance gains to be had by using a JDBCPreparedStatement object in
* preference to a JDBCStatement object when a short-running SQL statement is
* to be executed more than once. <p>
*
* When it can be otherwise avoided, it should be considered poor practice to
* fully prepare (construct), parameterize, execute, fetch and close a
* JDBCParameterMetaData object for each execution cycle. Indeed,
* because the prepare and execute phases
* both represent a round-trip to the engine, this practice is likely to be
* noticeably <em>less</em> performant for short-running statements (and
* possibly even orders of magnitude less performant over network connections
* for short-running statements) than the equivalent process using JDBCStatement
* objects, albeit far more convenient, less error prone and certainly much
* less resource-intensive, especially when large binary and character values
* are involved, due to the optimized parameterization facility. <p>
*
* Instead, when developing an application that is not totally oriented toward
* the execution of ad hoc SQL, it is recommended to expend some effort toward
* identifying the SQL statements that are good candidates for regular reuse and
* adapting the structure of the application accordingly. Often, this is done
* by recording the text of candidate SQL statements in an application resource
* object (which has the nice side-benefit of isolating and hiding differences
* in SQL dialects across different drivers) and caching for possible reuse the
* PreparedStatement objects derived from the recorded text. <p>
*
* Starting with 2.0, when built under a JDBC 4 environment, statement caching
* can be transparently enabled or disabled on a statement-by-statement basis by
* invoking setPoolable(true | false), respectively, upon Statement objects of
* interest. <p>
*
* <b>Multi thread use:</b> <p>
*
* A PreparedStatement object is stateful and should not normally be shared
* by multiple threads. If it has to be shared, the calls to set the
* parameters, calls to add batch statements, the execute call and any
* post-execute calls should be made within a block synchronized on the
* PreparedStatement Object.<p>
