SQL problem

[nanix]

No code compiles runs OK no errors.But ofcourse all functions work becouse previously some same functions are used to INSERT records

1.Set all parameters;

Delphi-Quellcode:

ABSQuery1.ParamByName('HWM_ID').AsString:=inttostr(hwm_index);
ABSQuery1.ParamByName('Sensor_Class').AsString:=inttostr(SENSOR_CLASS_VOLTAGE);
ABSQuery1.ParamByName('Sensor_ID').AsString:=inttostr(sensor_index);

2.Then populate the variables;

Delphi-Quellcode:

sField:=pansichar(ptrname);
sValue:=Format('%.3f V', [Value]);
sMin:=Format('%.3f V', [Min]);
sMax:=Format('%.3f V', [Max]);

3.Execute SQL script;
ABSQuery1.ExecSQL;
I am speculating the SQL text...

Conversion is not needed

Delphi-Quellcode:

ABSQuery1.ParamByName('HWM_ID').Value := hwm_index);
ABSQuery1.ParamByName('Sensor_Class').Value := SENSOR_CLASS_VOLTAGE;
ABSQuery1.ParamByName('Sensor_ID').Value := sensor_index;

You could use here parameters too:
UPDATE Sensors SET Field = :field ,value = :Value, Min = :min, Max = :max WHERE HWM_ID = :HWM_ID and Sensor_Class = :Sensor_Class and Sensor_ID = :Sensor_ID';

I tryed executing after and it makes no diffrence

Delphi-Quellcode:

for hwm_index := 0 to NBMonitors - 1 do begin

for sensor_index := 0 to CPUIDSDK_GetNumberOfSensors(hwm_index,  SENSOR_CLASS_VOLTAGE)  - 1 do begin
if CPUIDSDK_GetSensorInfos(hwm_index,
sensor_index,
SENSOR_CLASS_VOLTAGE,
ptrName,
iValue,
Value,
Min,
Max)
then begin
ABSQuery1.ParamByName('HWM_ID').AsString:=inttostr(hwm_index);
ABSQuery1.ParamByName('Sensor_Class').AsString:=inttostr(SENSOR_CLASS_VOLTAGE);
ABSQuery1.ParamByName('Sensor_ID').AsString:=inttostr(sensor_index);

sField:=pansichar(ptrname);
sValue:=Format('%.3f V', [Value]);
sMin:=Format('%.3f V', [Min]);
sMax:=Format('%.3f V', [Max]);

ABSQuery1.SQL.Clear;
ABSQuery1.SQL.Text := 'UPDATE Sensors SET Field="' +sField+'"' +','+'Value="'+sValue+'"'+','+'Min="'+sMin+'"'+','+'Max="'+sMax+'"'+' WHERE HWM_ID = :HWM_ID and Sensor_Class = :Sensor_Class and Sensor_ID = :Sensor_ID';
ABSQuery1.ExecSQL;
Edit1.Text:=ABSQuery1.SQL.Text;



end;
end;
end;
end;

Try parameters

Zitat von nanix:

I don't understand why it won't update Records

Edit:
Edit1.Text:=ABSQuery1.SQL.Text; Edit1 reports this

UPDATE Sensors SET Field="",Value="",Min="",Max="" WHERE HWM_ID = :HWM_ID and Sensor_Class = :Sensor_Class and Sensor_ID = :Sensor_ID

Do you still get these empty strings? Looks like the Values ([Value],[Min],[Max]) are empty or Format can`t convert them?!
Maybe the parameter '%.3f' breaks the function (doen't know, never worked with Format)?

[nanix]

No i get this in edit1

UPDATE Sensors SET Field="VIN3",Value="1.536 V",Min="1.536 V",Max="1.536 V" WHERE HWM_ID = :HWM_ID and Sensor_Class = :Sensor_Class and Sensor_ID = :Sensor_ID and it says this even tho its on timer 1 s interval

[ToFaceTeKilla]

Ok then i would guess its a database issue. What are the values of the parameters (:HWM_ID,...)? Are there database entries which match these? Because no match with "WHERE" - no update

[nanix]

I uploaded unit and db file i use its ABSOLUTE DATABASE.

[ToFaceTeKilla]

Sorry, but I don't know Absolute DB and how to use it. Can't you just lookup if your DB contains entries which match the parameters? Maybe you have something like a management tool for this kind of DB?

[nanix]

Its like any other DB..
