    • get

      public Object get(ResultSet rs, String columnLabel) throws SQLException
      Description copied from interface: JdbcSqlType
      Retrieves the value of the designated column in the current row of this ResultSet object as a Java type value.
      Specified by:
      get in interface JdbcSqlType
      Parameters:
      rs - a ResultSet instance
      columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
      Returns:
      the column value; if the value is SQL NULL, the value returned is null
      Throws:
      SQLException - if the columnLabel is not valid; if a database access error occurs or this method is called on a closed result set

    • set

      public void set(PreparedStatement st, int index, Object value) throws SQLException
      Description copied from interface: JdbcSqlType
      Sets the designated parameter to the given Java value. The JDBC driver converts this to the appropriate SQL type value.
      Specified by:
      set in interface JdbcSqlType
      Parameters:
      st - a PreparedStatement instance
      index - the first parameter is 1, the second is 2, ...
      value - the parameter value
      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

    • get

      public Object get(CallableStatement cs, int index) throws SQLException
      Retrieves the value of the designated parameter from CallableStatement object as a Java type value.
      Specified by:
      get in interface JdbcSqlType
      Parameters:
      cs - a CallableStatement instance
      index - the first parameter is 1, the second is 2, ...
      Returns:
      the parameter value; if the value is SQL NULL, the value depends on the Java type
      Throws:
      SQLException - if the parameterIndex is not valid; if a database access error occurs or this method is called on a closed CallableStatement
