  • Method Details

    • get

      Object get(ResultSet rs, String columnLabel) throws SQLException
      Retrieves the value of the designated column in the current row of this ResultSet object as a Java type value.
      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

      void set(PreparedStatement st, int index, Object value) throws SQLException
      Sets the designated parameter to the given Java value. The JDBC driver converts this to the appropriate SQL type value.
      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

      Object get(CallableStatement cs, int index) throws SQLException
      Retrieves the value of the designated parameter from CallableStatement object as a Java type value.
      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

    • getDatabaseSqlType

      Integer getDatabaseSqlType()
      Returns the type provided by the stack on top of which the SQL Processor works. It has to support null input/output values.
      Returns:
      the provided type
