1、可以使用number(10,2)来完成
2、DELPHI建立的索引与DBSAE所建立的索引是有差距的。两者并不能等同。
你完全可以使用TTABLE.CREATETABLE来建立DBF
例子:
if not Table1.Exists then begin
with Table1 do begin
{ The Table component must not be active }
Active := False;
{ First, describe the type of table and give }
{ it a name }
DatabaseName := 'dbase';
TableType := ttFoxpro;
TableName := 'CustInfo';
{ Next, describe the fields in the table }
with FieldDefs do begin
Clear;
with AddFieldDef do begin
Name := 'Field1';
DataType := ftInteger;
Required := True;
end;
with AddFieldDef do begin
Name := 'total';
DataType := ftfloat;
Required := True;
end;
with AddFieldDef do begin
Name := 'Field2';
DataType := ftString;
Size := 30;
end;
end;
{ Next, describe any indexes }
with IndexDefs do begin
Clear;
{ The 1st index has no name because it is
{ a Paradox primary key }
with AddIndexDef do begin
Name := 'Fldidx1';
Fields := 'Field1';
Options := [ixPrimary];
end;
with AddIndexDef do begin
Name := 'Fld2Indx';
Fields := 'Field2';
Options := [ixCaseInsensitive];
end;
end;
{ Call the CreateTable method to create the table }
CreateTable;
end;
end;
建议,使用ODBC来建立数据连接,再通过它来创建、访问DBASE。
