I was looking for a way to determine the number of columns in a ResultSet object when I encountered
ResultSetMetaData. With this class I only need to call on the getColumnCount() method
| String | getCatalogName(int column) | Gets the designated column's table's catalog name. |
| String | getColumnClassName(int column) | Returns the fully-qualified name of the Java class whose instances are manufactured if the method ResultSet.getObject is called to retrieve a value from the column. |
| int | getColumnCount() | Returns the number of columns in this ResultSet object. |
| int | getColumnDisplaySize(int column) | Indicates the designated column's normal maximum width in characters. |
| String | getColumnLabel(int column) | Gets the designated column's suggested title for use in printouts and displays. |
| String | getColumnName(int column) | Get the designated column's name. |
| int | getColumnType(int column) | Retrieves the designated column's SQL type. |
| String | getColumnTypeName(int column) | Retrieves the designated column's database-specific type name. |
| int | getPrecision(int column) | Get the designated column's number of decimal digits. |
| int | getScale(int column) | Gets the designated column's number of digits to right of the decimal point. |
| String | getSchemaName(int column) | Get the designated column's table's schema. |
| String | getTableName(int column) | Gets the designated column's table name. |
| boolean | isAutoIncrement(int column) | Indicates whether the designated column is automatically numbered, thus read-only. |
| boolean | isCaseSensitive(int column) | Indicates whether a column's case matters. |
| boolean | isCurrency(int column) | Indicates whether the designated column is a cash value. |
| boolean | isDefinitelyWritable(int column) | Indicates whether a write on the designated column will definitely succeed. |
| int | isNullable(int column) | Indicates the nullability of values in the designated column. |
| boolean | isReadOnly(int column) | Indicates whether the designated column is definitely not writable. |
| boolean | isSearchable(int column) | Indicates whether the designated column can be used in a where clause. |
| boolean | isSigned(int column) | Indicates whether values in the designated column are signed numbers. |
| boolean | isWritable(int column) | Indicates whether it is possible for a write on the designated column to succeed. |
