如何将参数值从表单传递给Report Builder?
还是有任何错误?
报告构建器SQL:
SELECT * FROM Member Where MemberID = :MemberID
表格代码:
procedure TfmRbTest.Button1Click(Sender: TObject);
begin
ppReport1.Template.FileName = 'Member.rtm'
ppReport1.Template.LoadFileName;
ppReport1.Parameters['MemberID'].Value := '000001';
ppReport1.Print;
end;

您没有提供足够的信息以确定,但这是我的猜测。
您需要注意参数类型。您生成的SQL是
SELECT * FROM Member where MemberID = 000001
如果MemberID是文字,则需要
SELECT * FROM Member where MemberID = '000001'
您将使用以下代码生成
procedure TfmRbTest.Button1Click(Sender: TObject);
begin
ppReport1.Template.FileName = 'Member.rtm'
ppReport1.Template.LoadFileName;
ppReport1.Parameters['MemberID'].Value := '''000001''';
ppReport1.Print;
end;
或者我认为您可以保留代码并将查询更改为
SELECT * FROM Member where MemberID = ':MemberID'
但我不是百分之百。
