| 46 | * <p> |
| 47 | * This class provides information about the database as a whole. |
| 48 | * </p> |
| 49 | * <p> |
| 50 | * Many of the methods here return lists of information in ResultSets. You can |
| 51 | * use the normal ResultSet methods such as getString and getInt to retrieve the |
| 52 | * data from these ResultSets. If a given form of metadata is not available, |
| 53 | * these methods show throw a SQLException. |
| 54 | * </p> |
| 55 | * <p> |
| 56 | * Some of these methods take arguments that are String patterns. These methods |
| 57 | * all have names such as fooPattern. Within a pattern String "%" means match |
| 58 | * any substring of 0 or more characters and "_" means match any one character. |
