com.mysql.jdbc
Class PreparedStatement

java.lang.Object
  com.mysql.jdbc.StatementImpl
      com.mysql.jdbc.PreparedStatement

All Implemented Interfaces:: java.sql.PreparedStatement, java.sql.Statement, java.sql.Wrapper

Direct Known Subclasses:: CallableStatement, JDBC4PreparedStatement, ServerPreparedStatement

public class PreparedStatement
extends StatementImpl
implements java.sql.PreparedStatement
extends StatementImpl
implements java.sql.PreparedStatement

A SQL Statement is pre-compiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

Note: The setXXX methods 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 Integer, then setInt should be used.

If arbitrary parameter type conversions are required, then the setObject method should be used with a target SQL type.

getParameterIndexOffset

protected int getParameterIndexOffset()

For calling stored functions, this will be -1 as we don't really count the first '?' parameter marker, it's only syntax, but JDBC counts it as #1, otherwise it will return 0

Set a parameter to a Java String value. The driver converts this to a SQL VARCHAR or LONGVARCHAR value with introducer _utf8 (depending on the arguments size relative to the driver's limits on VARCHARs) when it sends it to the database. If charset is set as utf8, this method just call setString.

Specified by:: setNString in interface java.sql.PreparedStatement

Parameters:: parameterIndex - the first parameter is 1...; x - the parameter value
Throws:: java.sql.SQLException - if a database access error occurs

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

Specified by:: setNCharacterStream in interface java.sql.PreparedStatement

Parameters:: parameterIndex - the first parameter is 1, the second is 2, ...; reader - the java reader which contains the UNICODE data; length - the number of characters in the stream
Throws:: java.sql.SQLException - if a database-access error occurs.
