BLOB
BLOB
| 定数 | 型 | 値 | コメント |
| Compact compression mode | 倍長整数 | 1 | 圧縮解凍の処理速度と引き換えに、BLOBをできるだけ小さく圧縮します。デフォルトモード。 |
| Extended real format | 倍長整数 | 1 | |
| Fast compression mode | 倍長整数 | 2 | 圧縮率と引き換えにBLOBをできるだけ速く圧縮・解凍します (圧縮されたBLOBのサイズは大きくなります)。 |
| GZIP best compression mode | 倍長整数 | -1 | GZIP圧縮で圧縮率を優先します。 |
| GZIP fast compression mode | 倍長整数 | -2 | GZIP圧縮で速度を優先します。 |
| Is not compressed | 倍長整数 | 0 | No compression |
| Mac C string | 倍長整数 | 0 | |
| Mac Pascal string | 倍長整数 | 1 | |
| Mac text with length | 倍長整数 | 2 | |
| Mac text without length | 倍長整数 | 3 | |
| Macintosh byte ordering | 倍長整数 | 1 | |
| Macintosh double real format | 倍長整数 | 2 | |
| Native byte ordering | 倍長整数 | 0 | |
| Native real format | 倍長整数 | 0 | |
| PC byte ordering | 倍長整数 | 2 | |
| PC double real format | 倍長整数 | 3 | |
| UTF8 C string | 倍長整数 | 4 | |
| UTF8 text with length | 倍長整数 | 5 | |
| UTF8 text without length | 倍長整数 | 6 |
