I have a below query in the stored procedure. And I have the invalid location #file_attachments.
BEGIN TRY
EXEC msdb.dbo.Sp_send_dbmail
#recipients='raja#gmail.com',
#subject='hello',
#body='hello',
#body_format='HTML',
#file_attachments='\\1.1.1.1\Image\Logo.png',
#profile_name='EmailDev'
END TRY
BEGIN CATCH
SELECT ERROR_NUMBER() AS ErrorNumber,
ERROR_MESSAGE() AS ErrorMessage
END CATCH
When I execute I'm getting this error:
Msg 22051, Level 16, State 1, Line 25
Attachment file \1.1.1.1\Image\Logo.png is invalid.
But I'm not able to capture this in error in the catch block, rather it is not hitting the catch block.
How to capture the error message in the catch block instead of the standard way of displaying an error?
Seems there is a problem sp_send_dbmail to capture the error in TRY CATCH block.
As per the suggestion on the thread
I have modified my code as below, which solves my problem.
BEGIN TRY
Declare #FileInfo Table(FileExist Int,IsDirectory Int,ParentDirectoryExist Int)
Declare #file_attachments VARCHAR(1000)
SET #file_attachments = '\\1.1.1.1\Image\Logo.png'
INSERT INTO #AtthacmentFileInfo EXEC XP_FILEEXIST #Attachment
IF (SELECT FileExist FROM #AtthacmentFileInfo)=0
BEGIN
SET #ErrMessage = 'Invalid logo location or it is not accessible. '+#Attachment+''
;THROW 50000,#ErrMessage,1;
END
EXEC msdb.dbo.Sp_send_dbmail
#recipients='raja#gmail.com',
#subject='hello',
#body='hello',
#body_format='HTML',
#file_attachments='\\1.1.1.1\Image\Logo.png',
#profile_name='echohealth'
END TRY
BEGIN CATCH
SELECT ERROR_NUMBER() AS ErrorNumber,
ERROR_MESSAGE() AS ErrorMessage

I'm following the tutorial on https://postgrest.org/en/v5.0/auth.html#jwt-from-sql
I created this function:
create or replace function
login(email text, pass text) returns basic_auth.jwt_token
language plpgsql
as $$
declare
_role name;
result basic_auth.jwt_token;
begin
-- check email and password
select basic_auth.user_role(email, pass) into _role;
if _role is null then
raise invalid_password using message = 'invalid user or password';
end if;
select sign(
row_to_json(r), 'reallyreallyreallyreallyverysafe'
) as token
from (
select _role as role, login.email as email,
extract(epoch from now())::integer + 60*60 as exp
) r
into result;
return result;
end;
$$;
When I try to do the login request, I get the following error message:
{
"hint": "No function matches the given name and argument types. You might need to add explicit type casts.",
"details": null,
"code": "42883",
"message": "function public.sign(json, unknown) does not exist" }
I don't see the sign function anywhere in the tutorial, does anyone know what is going on here?
The sign function is created when you install pgjwt.
Also, make sure that you install the extension on a schema that is included in your search_path(a list of imported schemas). This can be specified by doing CREATE EXTENSION pgjwt WITH SCHEMA public.
PostgREST adds the public schema by default on the search_path, so the extension should work with no additional config.
I'm trying to define some PostgreSQL functions and triggers in my JPA import.sql file. I'm using Hibernate 5.x as my underlying JPA provider. Since my import.sql file has commands that are multiple lines, I've got this property set in my persistence.xml file:
<property name="hibernate.hbm2ddl.import_files_sql_extractor" value="org.hibernate.tool.hbm2ddl.MultipleLinesSqlCommandExtractor" />
From there, I'm trying to define my functions in import.sql. They look something like this:
DROP FUNCTION IF EXISTS update_total_feedback_count() CASCADE;
CREATE FUNCTION update_total_feedback_count() RETURNS TRIGGER AS
$$
DECLARE
application_version_id BIGINT := 0;
app_version_metadata_id BIGINT:= 0;
application_id BIGINT := 0;
app_metadata_id BIGINT := 0;
BEGIN
IF (TG_OP = 'INSERT') THEN
SELECT INTO application_version_id tbl_application_version.id
FROM tbl_application_version
INNER JOIN tbl_feedback ON tbl_feedback.application_version_id = tbl_application_version.id
WHERE tbl_feedback.id = NEW.id;
SELECT INTO app_version_metadata_id tbl_application_version.application_version_metadata_id
FROM tbl_application_version
WHERE id = application_version_id;
SELECT INTO app_metadata_id registered_application_metadata_id
FROM tbl_registered_application
INNER JOIN tbl_application_version ON tbl_application_version.registered_application_id = tbl_registered_application.id
WHERE tbl_application_version.id = application_version_id;
UPDATE tbl_registered_application_metadata SET feedbackcount = (feedbackcount + 1), lastfeedbackdate = NEW.createddate WHERE id = app_metadata_id;
UPDATE tbl_application_version_metadata SET feedbackcount = (feedbackcount + 1), lastfeedbackdate = NEW.createddate WHERE id = app_version_metadata_id;
RETURN NEW;
ELSIF (TG_OP = 'DELETE') THEN
-- IMPLEMENT THIS TRIGGER
RETURN NULL;
END IF;
END;
$$
LANGUAGE 'plpgsql';
ALTER FUNCTION update_total_feedback_count() OWNER TO feedback_tracker;
However, when I deploy my WAR file, I get an error saying something like this:
Unterminated dollar quote started at position 65 in SQL CREATE
FUNCTION my_function() RETURNS TRIGGER AS $$
So, clearly it's dying on the $$ in my function declaration. Is there a way around this? Should I be declaring my function/trigger differently? Is there a property I can set in my persistence.xml file that will get around this?
the problem with hibernate's default SqlStatementParser implementation, which is used in multiline sql command extractor.
if you look at grammar definition hibernate-core/src/main/antlr/sql-stmt.g there is definition of Statement End:
STMT_END
: ';' ( '\t' | ' ' | '\r' | '\n' )*
;
NOT_STMT_END
: ~( ';' )
;
This tells that statement end is semicolon symbol followed by "Space" "tab" "carret return" or "new line" symbols.
THUS: DEFAULT IMPLEMENTATION IN HIBERNATE DOESN'T SUPPORT DOLLAR QUOTING.
If you don't want to implement custom hibernate's parser you can rewrite all functions without dollar quoting, using simple ' quoting. But you will need to carefully escape ' chars.
UPDATE: you can create your custom ImportSqlCommandExtractor. For example: separate your commands with --****** (6 star symbols in comment, just to make your file proper SQL file, but with custom command separation in comments, or choose any insane combination, which you like) and then split those in simple implementation
public class ImportSqlCE implements ImportSqlCommandExtractor {
private static final Logger log = LoggerFactory.getLogger(ImportSqlCE.class);
#Override
public String[] extractCommands(Reader reader) {
try {
String allCommands = IOUtils.toString(reader);
return allCommands.split("--******");
} catch (IOException e) {
log.error("error reading import commands", e);
log.info("sengind default empty command set");
return new String[0];
}
}
}
and then configure hibernate to use it <property name="hibernate.hbm2ddl.import_files_sql_extractor" value="example.ImportSqlCE" />
with this your import.sql will support dollar quoting (i.e. it will simply ignore any sql awareness of what is happening.)
I am using multiple forms on my project. (Client Server Application) I used chat but i have some problems.
1- I have a user list on my listview. And i am open new chat form here.
procedure CreateNewChat(User: String);
var
ChatForm: TChatForm;
begin
ChatForm:= TChatForm.Create(nil);
if assigned (ChatForm) then
ChatForm.User:= User;
Chat.Socket:= MySocket; // TClientSocket new Instance
ChatForm.Show;
end;
///Chatform
procedure ParseData(Cmd:string);
begin
if Cmd <> '' then
begin
/// parsing...
end;
New connections are adding to listview like that
var
Item: TListItem;
NewTempForm: TTempForm;
begin
NewTempForm := tempForm.Create;
Item := Listview.Items.Add;
if User = '' then
Exit;
Item.Caption := User;
Item.SubItems.Add('OK');
Item.GroupId := GroupId;
Item.SubItems.Objects[0] := NewTempForm;
end;
My problems are started on here.
1- How can i detect form according to user? So, if two or higher form is open then how can i show received message on them? Because i was create them dynamically. I need a object for detect.
I tryed like that
var
tempForm: TTempForm; // this is an empty object class
sTempStr: String;
begin
if ListView.Selected <> nil then
begin
tempForm := TTempForm(ListView.Selected.SubItems.Objects[0]); // this is for unique form creation
if tempForm.frmTasks = nil then // if there is not, create!
begin
tempForm.frmTasks := TfrmTasks.Create(nil);
end;
But my received message is appear on all forms. Actually should appear just one form. (Which user sent it)
Thanks.
I am preparing an installer with Inno Setup. But I'd like to add an additional custom (none of the available parameters) command line parameters and would like to get the value of the parameter, like:
setup.exe /do something
Check if /do is given, then get the value of something. Is it possible? How can I do this?
With InnoSetup 5.5.5 (and perhaps other versions), just pass whatever you want as a parameter, prefixed by a /
c:\> myAppInstaller.exe /foo=wiggle
and in your myApp.iss:
[Setup]
AppName = {param:foo|waggle}
The |waggle provides a default value if no parameter matches. Inno setup is not case sensitive. This is a particularly nice way to handle command line options: They just spring into existence. I wish there was as slick a way to let users know what command line parameters the installer cares about.
BTW, this makes both #knguyen's and #steve-dunn's answers somewhat redundant. The utility functions do exactly what the built-in {param: } syntax does.
Further to #DanLocks' answer, the {param:*ParamName|DefaultValue*} constant is documented near the bottom of the Constants page:
http://www.jrsoftware.org/ishelp/index.php?topic=consts
I found it quite handy for optionally suppressing the license page. Here is all I needed to add (using Inno Setup 5.5.6(a)):
[code]
{ If there is a command-line parameter "skiplicense=true", don't display license page }
function ShouldSkipPage(PageID: Integer): Boolean;
begin
Result := False
if PageId = wpLicense then
if ExpandConstant('{param:skiplicense|false}') = 'true' then
Result := True;
end;
Inno Setup directly supports switches with syntax /Name=Value using {param} constant.
You can use the constant directly in sections, though this use is quite limited.
An example:
[Registry]
Root: HKCU; Subkey: "Software\My Company\My Program\Settings"; ValueType: string; \
ValueName: "Mode"; ValueData: "{param:Mode|DefaultMode}"
You will more likely want to use switches in Pascal Script.
If your switch has the syntax /Name=Value, the easiest way to read its value is using ExpandConstant function.
For example:
if ExpandConstant('{param:Mode|DefaultMode}') = 'DefaultMode' then
begin
Log('Installing for default mode');
end
else
begin
Log('Installing for different mode');
end;
If you want to use a switch value to toggle entries in sections, you can use Check parameter and a auxiliary function, like:
[Files]
Source: "Client.exe"; DestDir: "{app}"; Check: SwitchHasValue('Mode', 'Client')
Source: "Server.exe"; DestDir: "{app}"; Check: SwitchHasValue('Mode', 'Server')
[Code]
function SwitchHasValue(Name: string; Value: string): Boolean;
begin
Result := CompareText(ExpandConstant('{param:' + Name + '}'), Value) = 0;
end;
Ironically it is more difficult to check for a mere presence of switch (without a value).
Use can use a function CmdLineParamExists from #TLama's answer to Passing conditional parameter in Inno Setup.
function CmdLineParamExists(const Value: string): Boolean;
var
I: Integer;
begin
Result := False;
for I := 1 to ParamCount do
if CompareText(ParamStr(I), Value) = 0 then
begin
Result := True;
Exit;
end;
end;
You can obviously use the function in Pascal Script:
if CmdLineParamExists('/DefaultMode') then
begin
Log('Installing for default mode');
end
else
begin
Log('Installing for different mode');
end;
But you can even use it in sections, most typically using Check parameter:
[Files]
Source: "MyProg.hlp"; DestDir: "{app}"; Check: CmdLineParamExists('/InstallHelp')
A related problem:
Add user defined command line parameters to /? window
If you want to parse command line arguments from code in inno, then use a method similar to this. Just call the inno script from the command line as follows:
c:\MyInstallDirectory>MyInnoSetup.exe -myParam parameterValue
Then you can call the GetCommandLineParam like this wherever you need it:
myVariable := GetCommandLineParam('-myParam');
{ ================================================================== }
{ Allows for standard command line parsing assuming a key/value organization }
function GetCommandlineParam (inParam: String):String;
var
LoopVar : Integer;
BreakLoop : Boolean;
begin
{ Init the variable to known values }
LoopVar :=0;
Result := '';
BreakLoop := False;
{ Loop through the passed in arry to find the parameter }
while ( (LoopVar < ParamCount) and
(not BreakLoop) ) do
begin
{ Determine if the looked for parameter is the next value }
if ( (ParamStr(LoopVar) = inParam) and
( (LoopVar+1) <= ParamCount )) then
begin
{ Set the return result equal to the next command line parameter }
Result := ParamStr(LoopVar+1);
{ Break the loop }
BreakLoop := True;
end;
{ Increment the loop variable }
LoopVar := LoopVar + 1;
end;
end;
This is the function I wrote, which is an improvement of Steven Dunn's answer. You can use it as:
c:\MyInstallDirectory>MyInnoSetup.exe /myParam="parameterValue"
myVariable := GetCommandLineParam('/myParam');
{ util method, equivalent to C# string.StartsWith }
function StartsWith(SubStr, S: String): Boolean;
begin
Result:= Pos(SubStr, S) = 1;
end;
{ util method, equivalent to C# string.Replace }
function StringReplace(S, oldSubString, newSubString: String): String;
var
stringCopy: String;
begin
stringCopy := S; { Prevent modification to the original string }
StringChange(stringCopy, oldSubString, newSubString);
Result := stringCopy;
end;
{ ================================================================== }
function GetCommandlineParam(inParamName: String): String;
var
paramNameAndValue: String;
i: Integer;
begin
Result := '';
for i := 0 to ParamCount do
begin
paramNameAndValue := ParamStr(i);
if (StartsWith(inParamName, paramNameAndValue)) then
begin
Result := StringReplace(paramNameAndValue, inParamName + '=', '');
break;
end;
end;
end;
Yes it is possible, you can use the ParamStr function in PascalScript to access all the commandline parameters. The ParamCount function will give you the number of commandline parameters.
Another possibility is to use GetCmdTail
In response to:
"With InnoSetup 5.5.5 (and perhaps other versions), just pass whatever you want as a parameter, prefixed by a /"
"#NickG, yes, every constant you can expand by the ExpandConstant function"
This is not the case. Trying to use a command line parameter in ExpandConstant in InnoSetup 5.5.6 results in a runtime error.
PS: I would have added a comment directly but apparently I dont have enough "reputation"
I've modified a little bit knguyen's answer. Now it's case insensitive (you can write en console /myParam or /MYPARAM) and it can accept default value. Also I fixed the case when you receive larger parameter then expected (for ex: /myParamOther="parameterValue" in place of /myParam="parameterValue". Now myParamOther doesn't match).
function GetCommandlineParam(inParamName: String; defaultParam: String): String;
var
paramNameAndValue: String;
i: Integer;
begin
Result := defaultParam;
for i := 0 to ParamCount do
begin
paramNameAndValue := ParamStr(i);
if (Pos(Lowercase(inParamName)+'=', AnsiLowercase(paramNameAndValue)) = 1) then
begin
Result := Copy(paramNameAndValue, Length(inParamName)+2, Length(paramNameAndValue)-Length(inParamName));
break;
end;
end;
end;
I found the answer: GetCmdTail.
You can pass parameters to your installer scripts. Install the Inno Setup Preprocessor and read the documentation on passing custom command-line parameters.
