在vfp中如果是dbf数据库，sql效率并不高。vfp中的sql基本属于标准sql，常用到的命令不多
，在vfp中只有select用的最多。
SELECT [ALL | DISTINCT] [TOP nExpr [PERCENT]]
[Alias.] Select_Item [AS Column_Name]
[, [Alias.] Select_Item [AS Column_Name] ...]
FROM [FORCE]
[DatabaseName!]Table [[AS] Local_Alias]
[[INNER | LEFT [OUTER] | RIGHT [OUTER] | FULL [OUTER] JOIN
DatabaseName!]Table [[AS] Local_Alias]
[ON JoinCondition …]
[[INTO Destination]
| [TO FILE FileName [ADDITIVE] | TO PRINTER [PROMPT]
| TO SCREEN]]
[PREFERENCE PreferenceName]
[NOCONSOLE]
[PLAIN]
[NOWAIT]
[WHERE JoinCondition [AND JoinCondition ...]
[AND | OR FilterCondition [AND | OR FilterCondition ...]]]
[GROUP BY GroupColumn [, GroupColumn ...]]
[HAVING FilterCondition]
[UNION [ALL] SELECTCommand]
[ORDER BY Order_Item [ASC | DESC] [, Order_Item [ASC | DESC] ...]]
这是vfp中的帮助，这个会了主要的就会了
