| 61 | /** |
| 62 | * A ResultSet provides access to a table of data generated by executing a |
| 63 | * Statement. The table rows are retrieved in sequence. Within a row its column |
| 64 | * values can be accessed in any order. |
| 65 | * |
| 66 | * <P> |
| 67 | * A ResultSet maintains a cursor pointing to its current row of data. Initially |
| 68 | * the cursor is positioned before the first row. The 'next' method moves the |
| 69 | * cursor to the next row. |
| 70 | * </p> |
| 71 | * |
| 72 | * <P> |
| 73 | * The getXXX methods retrieve column values for the current row. You can |
| 74 | * retrieve values either using the index number of the column, or by using the |
| 75 | * name of the column. In general using the column index will be more efficient. |
| 76 | * Columns are numbered from 1. |
| 77 | * </p> |
| 78 | * |
| 79 | * <P> |
| 80 | * For maximum portability, ResultSet columns within each row should be read in |
| 81 | * left-to-right order and each column should be read only once. |
| 82 | * </p> |
| 83 | * |
| 84 | * <P> |
| 85 | * For the getXXX methods, the JDBC driver attempts to convert the underlying |
| 86 | * data to the specified Java type and returns a suitable Java value. See the |
| 87 | * JDBC specification for allowable mappings from SQL types to Java types with |
| 88 | * the ResultSet getXXX methods. |
| 89 | * </p> |
| 90 | * |
| 91 | * <P> |
| 92 | * Column names used as input to getXXX methods are case insenstive. When |
| 93 | * performing a getXXX using a column name, if several columns have the same |
| 94 | * name, then the value of the first matching column will be returned. The |
| 95 | * column name option is designed to be used when column names are used in the |
| 96 | * SQL Query. For columns that are NOT explicitly named in the query, it is best |
| 97 | * to use column numbers. If column names were used there is no way for the |
| 98 | * programmer to guarentee that they actually refer to the intended columns. |
| 99 | * </p> |
| 100 | * |
| 101 | * <P> |
| 102 | * A ResultSet is automatically closed by the Statement that generated it when |
| 103 | * that Statement is closed, re-executed, or is used to retrieve the next result |
| 104 | * from a sequence of multiple results. |
| 105 | * </p> |
| 106 | * |
| 107 | * <P> |
| 108 | * The number, types and properties of a ResultSet's columns are provided by the |
| 109 | * ResultSetMetaData object returned by the getMetaData method. |
| 110 | * </p> |
