procedure TForm1.ADOTable1SEXGetText(Sender: TField; var Text: String; DisplayText: Boolean); begin if Sender.AsString='0' then Text:='男' else Text:='女'; end;
或者 在ADOQueryCalcFields事件里写 if not Dataset.FieldByName('BitName').AsBoolean then Dataset.FieldByName('bitname').Value:='是'; else Dataset.FieldByName('bitname').Value:='否';
在sql语句中用case: select field1,case field2 when 1 then 是,when 2 then 否 end,field3……
(Field As TBooleanField).DisplayValues :=Format('%s;%s ',['是','否']);
VCL Reference TBooleanField.DisplayValuesTBooleanField See alsoControls how the Boolean field is translated to and from display format.property DisplayValues: string;DescriptionUse DisplayValues to specify strings the field uses to represent Boolean values. Use any pair of phrases, separated by a semicolon. For example, to have the True and False values correspond to the letters T and F, respectively, set DisplayValues as follows:Table1LogicalField.DisplayValues := 'T;F';Similarly, to set the values of True and False to the strings Yes and No, set DisplayValues to Table1LogicalField.DisplayValues := 'Yes;No';The string associated with True or False can be an empty string. To set the value for True to an empty string, set DisplayValues to a string that begins with a semicolon. For example, to associate False with the string Fail, and True with an empty string, set DisplayValues toTable1LogicalField.DisplayValues := ';Fail';To associate False with an empty string, set DisplayValues to the string for True, with no semicolon at all.The strings associated with True and False by DisplayValues appear in data-aware controls when they display the data for a Boolean field. If one of the strings is an empty string, Boolean values associated with that string appear blank in data-aware controls.These strings are also used when getting or setting the Boolean field抯 AsString property. //参考如下代码～～ //也可以静态设置～～ procedure TForm1.Table1AfterOpen(DataSet: TDataSet); begin TNumericField(DataSet.FieldByName('数值字段')).DisplayFormat := '"否";"是";"是"'; TBooleanField(DataSet.FieldByName('逻辑字段')).DisplayValues := '是;否'; end;
设数据集adotable的字段为静态字段:在方法中： procedure TForm1.ADOTable1SEXGetText(Sender: TField; var Text: String; DisplayText: Boolean); begin if Sender.Asinteger = 1 then Text:='是' else Text:='否'; end;
建议用Ehlib,我就是这么用的,很方便的.
select sexgb = case sex when 0 then '男' when 1 then '女' end from employee
在查询时可直接按以上的语句取值，则在查询到的内容里有此一项，可用DBGRID直接关联此项 select sexgb = case sex when 0 then '男' when 1 then '女' end from employee
select '是否' = (case 字段名 when 0 then '否' when 1 then '是' end) from tablename
DisplayText: Boolean);
begin
if Sender.AsString='0' then
Text:='男' else Text:='女';
end;
BitID Content
1 是
0 否
BitID与你的那个bit字段对应
然后,在ADOQuery里新加一个LookUp字段,字段明:BitID,
Keyfield-> BitID
DataSet-> BitContent
LookUp keys-> BitID(BitContent里面的)
它的ResultField对应Content即可
在ADOQueryCalcFields事件里写
if not Dataset.FieldByName('BitName').AsBoolean then
Dataset.FieldByName('bitname').Value:='是';
else
Dataset.FieldByName('bitname').Value:='否';
select field1,case field2 when 1 then 是,when 2 then 否 end,field3……
新建一个计算字段也可以 dataset.CalcFields事件

更改： “是”与“否”中间是分号
