Congratulations!
thank you very much for your answer, mormot has been applied to my production environment(currently very small),it's fantastic
can mormot1 run in Docker?
你可以试试这个: utf8tocp936(stringtoutf8(errMsg))
Just because I need to synchronize some data to MSSQL, but there are some deletion operations , which results in unequal IDs on both sides. Therefore, I need count (*) to determine where to continue synchronizing.(Mainly because I didn't consider the issue of deletion at the beginning) 。
I have been using Mormot, which is a great framework。
Thank you very much for your answer。
I did not use the 'where' condition, just simply obtained the total number of tables. I will try again:)
If an index other than the ID field is created, the count (*) speed of sqlite will increase significantly, resulting in a data overhaul of 10000000 entries. Who knows why?
Only ID index 4s
Add another index 1.3s
Thank you for your answer.
If you don't use MongoDB cluster and only rely on sqlite, is there a feasible method for statistical analysis of Big data?:)
I understand, thank you. I still prefer sqlite for updates. It is very convenient and meets most needs, right?
Just to ask, why doesn't sqlite be used for this test?
Thank you. I'll try it later
I want to use Mormot to create a PDF file that supports Chinese fonts, such as' 宋体 ',Can someone give me a simple demo? Thank you very much。
(i use lazarus with fpc3.2.2)
@Aknehsas 您好,我也遇到了同样的问题,能提供一个例子吗?包含dll(如果需要的话),十分感谢。
I'll look into the compiler again, and thank you.
this is my code :
var
stmt: ISQLDBRows;
oledbP: TOleDBMSSQLConnectionProperties;
begin
oledbP := TOleDBMSSQLConnectionProperties.Create(oleServer, oleDB, oleUser, olePwd);
try
stmt := oledbP.Execute('select * from test ', []);
while stmt.Step do
begin
//do something
end;
finally
stmt.ReleaseRows;
stmt := nil; -------> call memory leaks (Use Heaptrc Unit check for mem-leaks)(-gh)
oledbP.Free;
end;
end;
lazarus --2.2.0
fpc --3.2.2
ISQLDBRows always causes memory leaks in lazarus(fpc3.2.2)
When executed
The ReleaseRows method and then set it to nil
have a good time
我们拭目以待:)
Thank you~~
Does SynMongoDB support transactions? I didn't find it?
Very clear, much appreciated.
In this case, do I have to use transactions?
(for Some concurrent modification operations...)
I see, thanks。:)
with mormot+sqlite can i set Isolation level ?
for Some concurrent modification operations...
great job! thanks~
Thank you very much for your answer
Are there actual cases of big data volume and concurrency?
I am very interested in this framework, usually use mssql, I don't know if I can switch to mormot+sqlite
Thanks for answer ?
