Interface SqlTypeValue

All Known Subinterfaces:
  DisposableSqlTypeValue, SqlXmlValue

All Known Implementing Classes:
  AbstractSqlTypeValue, SqlLobValue

    public interface SqlTypeValue

Interface to be implemented for setting values for more complex database specific types not supported by the standard setObject method.

Implementations perform the actual work of setting the actual values. They must implement the callback method `setTypeValue` which can throw SQLExceptions that will be caught and translated by the calling code. This callback method has access to the underlying Connection via the given PreparedStatement object, if that should be needed to create any database-specific objects.

  1.1

Field Summary
`static int` `TYPE_UNKNOWN` Constant that indicates an unknown (or unspecified) SQL type.

Method Summary
`void` `setTypeValue(PreparedStatement ps, int paramIndex, int sqlType, String typeName)` Set the type value on the given PreparedStatement.

Field Detail

### TYPE_UNKNOWN

    static final int TYPE_UNKNOWN

  Constant that indicates an unknown (or unspecified) SQL type. Passed into `setTypeValue` if the original operation method does not specify a SQL type.

Method Detail

### setTypeValue

    void setTypeValue(PreparedStatement ps,
                      int paramIndex,
                      int sqlType,
                      String typeName)
                      throws SQLException

  Set the type value on the given PreparedStatement.

  Parameters:
    `ps` - the PreparedStatement to work on
    `paramIndex` - the index of the parameter for which we need to set the value
    `sqlType` - SQL type of the parameter we are setting
    `typeName` - the type name of the parameter (optional)
  Throws:
    `SQLException` - if a SQLException is encountered setting parameter values (that is, there's no need to catch SQLException)
