This is an error I had sometimes when using an FDQuery on a Form and the related FDConnection in a DataModule. I do not hide from you that this has the gift of annoying me, especially when I use the visual designer of LiveBindings and my DataModule is in the list of uses

not my mother tongue too Yes, here I miss some words I think I am not a fan of the WITH but, sometimes using it by lazyness

Something like : const SQL = // asSQltext with TFDQuery.Create(self) do begin connection:=fdconnection; SQL.Text:=SQL; //parambyName //macrobyname Open; // processing Close; end; or const SQL = 'your sql'; var Q : TFDQuery; Q:=TFDQuery.Create(self); try Q.Connection:=FDConnection; Q.SQL.Text:=SQL; //Q.ParamByName //Q.macrobyName Q.Open; // processing Q.Close; finally Q.Free; end;

Stano Ok, my response is in three parts. 1- The first is only a Firebird compliant SQL on how to use DATEADD function, and for the question asked, just sufficient. 2- Why I am not fan of the subquery ? Because it is evaluated at each row of MYTABLE . Perhaps a CTE should be better, but with the so poor data sample I am lazy to test over WITH X AS (SELECT MAX(DATEADD(-10 DAYS FROM TDATE)) MD FROM MYTABLE) SELECT M.ID,M.TNAME,M.TDATE,M.INVNO FROM MYTABLE M JOIN X ON 1=1 WHERE M.TNAME='AA' AND (TDATE>=X.MD OR M.INVNO IS NULL) Note that I prefer the list of each column to an * 3- Delphi side, yes there is code (much more lines and I don't create an runtime TFDQuery .... ) but queries with parameters is, I think is a very usefull technique (I use for years)

Hi, - what is this X.INVRNO ? Your test table only contains INVNO column ! - use DateAdd Firebird function to compute your old date parameter DATEADD(-10 DAYS FROM SELECT MAX(TDATE) FROM MYTABLE )) or SELECT MAX(DATEADD(-10 DAYS FROM TDATE)) FROM MYTABLE I am not fan of sub-querys I should certainly prefer a Delphi Code based (we are in a Delphi forum 😉) and a Firedac query with parameters and macro (for the in clause) var d : variant; begin YourFDquery.Close; d:=FDConnection.ExecSQLScalar('SELECT MAX(DATEADD(:g DAYS FROM TDATE)) FROM MYTABLE',[-10]) // in this way you can change day number if not VarisEmpty(d) then begin YourFDQuery.SQl.text('SELECT * FROM MYTABLE WHERE (TDATE >= :d or INVNO IS NULL) &inmacro'); YourFDQuery.ParamByName('d').asDateTime:=d; yourFDquery.MacroByName('inmacro').asRaw:='AND TNAME IN (''AA'')'; // so you can easily change, i.e *using format or clear clause yourFDQuery.Open; end; Ok, I change position of the IN clause to easily clear the clause but, you can modify SQL text to YourFDQuery.SQl.text('SELECT * FROM MYTABLE WHERE &inmacro (TDATE>=:D OR INVNO IS NULL)'); YourFDQuery.ParamByName('d').asDateTime:=d; yourFDquery.MacroByName('inmacro').asRaw:='TNAME IN (''AA'') AND'; * "inmacro" can be computed by a format, var mymacro : String; begin mymacro:=Format('TNAME IN (%s) AND',[list_of_quoted_tname]);

I didn't see it was ADOQuery until I zoom picture ! (I don't even understand how we can still use it, but I hate ADO for a long time now) Firedac is my prefered set of database components

And question is ?

Clearly, you have a Datasource component with property AutoEdit set to True. So, when you change cuurent record, close table, etc. value of TDBEdit is "saved" Yes, but I have a crystal ball The BeforePost event if you want to update the table i.e procedure tb_dm_presentation_design_linksBeforePost(DataSet: TDataSet); begin tb_dm_presentation_design_links.FieldByName('LAST_UPDATE').asDateTime:=now; tb_dm_presentation_design_links.FieldByName('LAST_USER').asString:=mygetuserfunction; end; The AfterPost event if you record changes in another table (using an insert Query) procedure tb_dm_presentation_design_linksAfterPost(DataSet: TDataSet); begin // anAdoQuery.SQL.Text:='INSERT INTO TRACKS (USER,DATE_UPDATE) VALUES (:U,:D)'; // sorry not sure of syntax I am not fan of ADO anAdoQuery.Params.ParambyName('U').asString:=mygetuserfunction; anAdoQuery.Params.ParambyName('U').asDateTime:=now; anAdoQuery.ExecSQL; end; Now if you want to track only a set of columns, BeforePost is the event where you can check CurValue and NewValue (well with ADO I am not sure). if tb_dm_presentation_design_linkscust_upc.curvalue.asString<>tb_dm_presentation_design_linkscust_upc.Newvalue.asString then // insert query N.B. Know that SGBDR (good ones) triggers can track this for you without Delphi code. But this SGBD you use, my crystal ball, don't show me🔮 P.S. As I remember, but never in more than 20 years, there is also an OnChange event for fields (if fields are defined, and that seems to be the fact tb_dm_presentation_design_linkscust_upc)

Not really related to the question! Check in the file firebird.conf if IPv6V6Only is not set to 1 (around line 712) Check also AuthServer and AuthClient values (chapter around line 397) To have IP_V4 only I Found this explanation But, systemd configuration files ⁉️ I don't think you will find them (this explanation was for CENTOS 7) I don't think changing the RemoteServicePort value to 0.0.0.0:3050 (around line 667) should be a good idea, (idea I can't check), but you can have a try Now, according to this https://www.firebirdsql.org/file/documentation/html/en/firebirddocs/isql/firebird-isql.html#isql-connect-connection-string-url So if you use INET4 to connect to your database instead of INET you will certainly have IP_V4 address in your MON$ATTACHMENTS table. How ? Certainly 2 ways - modifying firebird.conf RemoteBindAddress (around line 725) setting it to INET4 but this should be restricting I think - by delphi code at connexion (depending on components used)

Hi, You can backup your database even if there are users connected ("warm backup") Yes

In FMX there are no DBGrid, DBEdit, DBxxxx controls. You have to bind your datas to controls (Grid, Edit ...) using Livebindings

Reflexion 1- as I remember , FreeReport is an ancestor or fork of FastReport Reflexion 2- BDE can still be installed (you have to download it from your registered product panel

Hi, I report my success on my full Ubuntu PC upgraded to Ubuntu 20.4 I failed installation of 20.4 for WSL (not installation but XFCE4 don't work fine, no terminal !) So I will still investigate about 18.04 version failure.

Hi Vincent, Well I test with WSL and a full Ubuntu PC but always with 18.04, Have this one now ! I use the GitHub SKIA version installer (not the getit one). OK so, next step for me : installing Ubuntu 20.04 (it's time 😉) first on my WSL.

Hi, Freanch Delphi Entreprise 11.1 (patch 1 now) and Ubuntu 18.04 is my target. Well, it's not a blank one (only a SkiaLabel added), I'll investigate further for this zlib1g-dev and test a blank project in debug mode. Thanks

Hi, Change the "Windows 10 Desktop" style to "Default". The best way to do that is to remove "Default" style and then rename "Windows 10 Desktop" to blank

Hi, It worked as expected on Android, but I can't test on Ubuntu I first have a problem of a lacking package I think it was zlib1g-dev, I install this one. But, if now I can deploy my project or the demo the program don't run. What did I miss ? Is there any doc/help for a "good" deployment ?

Not so, but I try to be 😉 And did you finally find the Arlésienne Yes, I don't remember where I was confronted to that checkbox. I think it was a question in www.developpez.net/forums and don't report it to my blog Ah finally, I see where https://www.developpez.net/forums/blogs/138527-sergiomaster/b8177/fmx-selection-delements-tlistview/ I.3 part The mayor part is here, but I skipped the OnclickEx part (sorry)

Ha, sorry to miss this one yesterday (still in Yeu). I wrote something like that in my blog, in a tutorial or in a response in a forum, I don't remember exactly where, only the image I used for demo. But, as I remember, I don't use positions but the ItemObject name

Have a look at http://www.fmxrtl.com/info.php

Hi Some useless .00000 here ! You have to learn about how Firebird do the job with scales don't remember where I read this in doc, but you can see here some instructions So if you use the SQL you have, before casting, a 13 scaled variable ! SELECT CAST(10 / 0.3048* 14.7776 AS NUMERIC(13,2)) FROM RDB$DATABASE This work also

Well, your SQL is the first and easy way to get the line with Firebird < 3.0 With Firebird 3+ perhaps a windows analytical function can be used WITH C AS (SELECT CUSTNO,LAST(TDATE) OVER (ORDER BY TDATE) D FROM MYTABLE WHERE CUSTNO=:CUSTNO ) SELECT M.TDATE,M.AA,M.BB FROM MYTABLE M LEFT JOIN C ON C.CUSTNO=M.CUSTNO AND M.TDATE=C.D But IMO, advantage is null, and if you have more than one line with CUSTNO,TDATE identical you will get more than one line

Or you can edit DevicePresets.xml file in C:\Users\<user_name>\AppData\Roaming\Embarcadero\BDS\22.0 But I think you have to restart your IDE to have changes applied

You're welcome
