public class AS400JDBCPreparedStatementImpl
extends AS400JDBCPreparedStatement
```
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.

  - executeBatch
```
public int[] executeBatch()
                   throws SQLException
```
    Runs the batch of SQL statements. Batch updates can be used to submit a set of SQL statements together as a single unit. The SQL statements are run in the order in which they were added to the batch. The batch is cleared after the SQL statements are run. In addition, this closes the current result set and clears warnings before executing the new SQL statement.
    When batch updates are run, autocommit should usually be turned off. This allows the caller to decide whether or not to commit the transaction in the event that an error occurs and some of the SQL statements in a batch fail to run.
    
    Specified by:
    
    executeBatch in interface Statement
    
    Specified by:
    
    executeBatch in class AS400JDBCPreparedStatement

    Runs an SQL INSERT, UPDATE, or DELETE statement, or any SQL statement that does not return a result set and makes any auto-generated keys for the columns indicated in the given array available for retrieval using Statement.getGeneratedKeys(). This closes the current result set and clears warnings before executing the new SQL statement.
    This method is not supported when connecting to IBM i V5R4 or earlier systems.
    
    Specified by:
    
    executeUpdate in interface Statement

    Sets the designated parameter to a InputStream object. This method differs from the setBinaryStream (int, InputStream) method because it informs the driver that the parameter value should be sent to the server as a BLOB. When the setBinaryStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARBINARY or a BLOB

    Sets the designated parameter to a Reader object. This method differs from the setCharacterStream (int, Reader) method because it informs the driver that the parameter value should be sent to the server as a CLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARCHAR or a CLOB
    Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setClob which takes a length parameter.
    
    Specified by:
    
    setClob in interface PreparedStatement
    
    Specified by:
    
    setClob in class AS400JDBCPreparedStatement
    
    Parameters:
    
    parameterIndex - The parameter index (1-based).
    
    reader - An object that contains the data to set the parameter value to.
    
    Throws:
    
    SQLException - If a database error occurs. if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatementor if parameterIndex does not correspond to a parameter marker in the SQL statement
  - setNCharacterStream
```
public void setNCharacterStream(int parameterIndex,
                                Reader value)
                         throws SQLException
```
    Sets the designated parameter to a Reader object. The Reader reads the data till end-of-file is reached. The driver does the necessary conversion from Java character format to the national character set in the database.
    Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
    Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setNCharacterStream which takes a length parameter.
    
    Specified by:
    
    setNCharacterStream in interface PreparedStatement
    
    Specified by:
    
    setNCharacterStream in class AS400JDBCPreparedStatement
    
    Parameters:
    
    parameterIndex - The parameter index (1-based).
    
    value - the parameter value
    
    Throws:
    
    SQLException - If a database error occurs. if parameterIndex does not correspond to a parameter marker in the SQL statement; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; if a database access error occurs; or this method is called on a closed PreparedStatement
  - setNClob
```
public void setNClob(int parameterIndex,
                     Reader reader)
              throws SQLException
```
    Sets the designated parameter to a Reader object. This method differs from the setCharacterStream (int, Reader) method because it informs the driver that the parameter value should be sent to the server as a NCLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGNVARCHAR or a NCLOB
    Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setNClob which takes a length parameter.
    
    Specified by:
    
    setNClob in interface PreparedStatement
    
    Specified by:
    
    setNClob in class AS400JDBCPreparedStatement
    
    Parameters:
    
    parameterIndex - The parameter index (1-based).
    
    reader - An object that contains the data to set the parameter value to.
    
    Throws:
    
    SQLException - If a database error occurs. if parameterIndex does not correspond to a parameter marker in the SQL statement; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; if a database access error occurs or this method is called on a closed PreparedStatement
  - setObject
```
public void setObject(int parameterIndex,
                      Object x,
                      SQLType targetSqlType,
                      int scaleOrLength)
               throws SQLException
```
    Sets the value of the designated parameter with the given object. If the second argument is an InputStream then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate a SQLException when the prepared statement is executed.
    The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.
    Note that this method may be used to pass database-specific abstract data types.
    
    Specified by:
    
    setObject in interface PreparedStatement
    
    Specified by:
    
    setObject in class AS400JDBCPreparedStatement
    
    Parameters:
    
    parameterIndex - - the first parameter is 1, the second is 2, ...
    
    x - - the object containing the input parameter value
    
    targetSqlType - - the SQL type to be sent to the database. The scale argument may further qualify this type.
    
    scaleOrLength - - for java.sql.JDBCType.DECIMAL or java.sql.JDBCType.NUMERIC types, this is the number of digits after the decimal point. For Java Object types InputStream and Reader, this is the length of the data in the stream or reader. For all other types, this value will be ignored.
    
    Throws:
    
    SQLException - - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement or if the Java Object specified by x is an InputStream or Reader object and the value of the scale parameter is less than zero
  - setObject
```

                      SQLType targetSqlType)
               throws SQLException
```
    Sets the value of the designated parameter with the given object. This method is similar to setObject(int parameterIndex, Object x, SQLType targetSqlType, int scaleOrLength), except that it assumes a scale of zero.

  - isWrapperFor
```
public boolean isWrapperFor(Class<?> iface)
                     throws SQLException
```
    Returns true if this either implements the interface argument or is directly or indirectly a wrapper for an object that does. Returns false otherwise. If this implements the interface then return true, else if this is a wrapper then return the result of recursively calling isWrapperFor on the wrapped object. If this does not implement the interface and is not a wrapper, return false. This method should be implemented as a low-cost operation compared to unwrap so that callers can use this method to avoid expensive unwrap calls that may fail. If this method returns true then calling unwrap with the same argument should succeed.
    
    Specified by:
    
    isWrapperFor in interface Wrapper
    
    Parameters:
    
    iface - a Class defining an interface.
    
    Returns:
    
    true if this implements the interface or directly or indirectly wraps an object that does.
    
    Throws:
    
    SQLException - If a database error occurs. if an error occurs while determining whether this is a wrapper for an object with the given interface.
  - unwrap
```
public <T> T unwrap(Class<T> iface)
             throws SQLException
```
    Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy. If the receiver implements the interface then the result is the receiver or a proxy for the receiver. If the receiver is a wrapper and the wrapped object implements the interface then the result is the wrapped object or a proxy for the wrapped object. Otherwise return the the result of calling unwrap recursively on the wrapped object or a proxy for that result. If the receiver is not a wrapper and does not implement the interface, then an SQLException is thrown.
    
    Specified by:
    
    unwrap in interface Wrapper
    
    Parameters:
    
    iface - A Class defining an interface that the result must implement.
    
    Returns:
    
    an object that implements the interface. May be a proxy for the actual implementing object.
    
    Throws:
    
    SQLException - If a database error occurs. If no object found that implements the interface
