59 | /** |
60 | * A ResultSet provides access to a table of data generated by executing a |
61 | * Statement. The table rows are retrieved in sequence. Within a row its column |
62 | * values can be accessed in any order. |
63 | * |
64 | * <P> |
65 | * A ResultSet maintains a cursor pointing to its current row of data. Initially |
66 | * the cursor is positioned before the first row. The 'next' method moves the |
67 | * cursor to the next row. |
68 | * </p> |
69 | * |
70 | * <P> |
71 | * The getXXX methods retrieve column values for the current row. You can |
72 | * retrieve values either using the index number of the column, or by using the |
73 | * name of the column. In general using the column index will be more efficient. |
74 | * Columns are numbered from 1. |
75 | * </p> |
76 | * |
77 | * <P> |
78 | * For maximum portability, ResultSet columns within each row should be read in |
79 | * left-to-right order and each column should be read only once. |
80 | * </p> |
81 | * |
82 | * <P> |
83 | * For the getXXX methods, the JDBC driver attempts to convert the underlying |
84 | * data to the specified Java type and returns a suitable Java value. See the |
85 | * JDBC specification for allowable mappings from SQL types to Java types with |
86 | * the ResultSet getXXX methods. |
87 | * </p> |
88 | * |
89 | * <P> |
90 | * Column names used as input to getXXX methods are case insenstive. When |
91 | * performing a getXXX using a column name, if several columns have the same |
92 | * name, then the value of the first matching column will be returned. The |
93 | * column name option is designed to be used when column names are used in the |
94 | * SQL Query. For columns that are NOT explicitly named in the query, it is best |
95 | * to use column numbers. If column names were used there is no way for the |
96 | * programmer to guarentee that they actually refer to the intended columns. |
97 | * </p> |
98 | * |
99 | * <P> |
100 | * A ResultSet is automatically closed by the Statement that generated it when |
101 | * that Statement is closed, re-executed, or is used to retrieve the next result |
102 | * from a sequence of multiple results. |
103 | * </p> |
104 | * |
105 | * <P> |
106 | * The number, types and properties of a ResultSet's columns are provided by the |
107 | * ResultSetMetaData object returned by the getMetaData method. |
108 | * </p> |
