1.表结构如下（预算数据明细表）：
CREATE TABLE [dbo].[BA_FeeDetail](
[ID] [int] IDENTITY(1,1) NOT NULL,
[FeeDeptID] [nvarchar](4) NULL,
[FeeDate] [int] NULL,
[FeeCode] [nvarchar](10) NULL,
[FeeType] [nvarchar](1) NULL,
[BAType] [nvarchar](1) NULL,
[FeeAmt] [float] NULL
) ON [PRIMARY]
2.创建存储过程（用于取得某部门某次预算的某月某费目的预算额）
CREATE PROCEDURE [dbo].[GetBudgetAmt]
-- Add the parameters for the stored procedure here
@DeptID nvarchar(4) = '7120',
@FeeDate int = 201301,
@FeeCode nvarchar(8) ='31301' ,
@FeeType nvarchar(1) = '2',
@BAType nvarchar(1)='1',
@FeeAmt float output
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
SELECT @FeeAmt = FeeAmt from BA_FeeDetail where (
FeeCode = @FeeCode and
FeeType = @FeeType and
FeeDate = @FeeDate and
FeeDeptID = @DeptID and
BAType = @BAType
)
Return @FeeAmt
END
3.delphi 程序中调用（使用ADOConnect 和 ADOStoreProc ）
procedure TForm1.btn1Click(Sender: TObject);
Var
BudgetAmt:Single;
begin
with ADOSP1 do
begin
ProcedureName :='GetBudgetAmt';
Parameters.Refresh; //必须有本语句，刷新参数
Parameters.ParamByName('@DeptID').Value:=EdtDept.Text;
Parameters.ParamByName('@FeeDate').Value:=EdtFeeDate.Text;
Parameters.ParamByName('@FeeCode').Value:=EdtFeeCode.Text;
Parameters.ParamByName('@FeeType').Value:=EdtFeeType.Text;
Parameters.ParamByName('@BAType').Value:=EdtBAType.Text;
Parameters.ParamByName('@FeeAmt').Value:=0.00;
ExecProc;
BudgetAmt:=Parameters.ParamByName('@FeeAmt').Value;
edtFeeAmt.Text:=Format('%.2f',[BudgetAmt]);
end;
end;
