一般最常用的就是字元,邏輯,日期,數值,備註這幾個型態~其實這些型態就是從早期 dBase 就存在的了;其他的型態則是 Visual FoxPro 所擴充出來的. | 一般最常用的就是字元,邏輯,日期,數值,備註這幾個型態~其實這些型態就是從早期 dBase 就存在的了;其他的型態則是 Visual FoxPro 所擴充出來的. | ||

欄位型態
VFP 所支援的欄位型態有這些:
| 欄位型態 | 欄位長度 | 小數點 | 資料型態 |
|---|---|---|---|
| C | n | – | 長度為n的字元欄位,用來存放字元或是字串 |
| D | – | – | 日期 |
| T | – | – | 日期時間 |
| N | n | d | 長度為n,小數點d位的數值欄位 |
| F | n | d | 長度為n,小數點d位的單精度浮點數值欄位 |
| I | – | – | 整數 |
| B | – | d | 雙精度浮點數 |
| Y | – | – | 貨幣型態 |
| L | – | – | 邏輯 |
| M | – | – | 備註 |
| G | – | – | 通用 |
一般最常用的就是字元,邏輯,日期,數值,備註這幾個型態~其實這些型態就是從早期 dBase 就存在的了;其他的型態則是 Visual FoxPro 所擴充出來的.
