Hi Bhavesh,
This is a common thing with 3rd party systems and engines (like SQlite) etc.
One day, you made a simple query which did not specify the output
specifically (or the format, or the order, or such), BUT you liked the
output as it was on that day, and then possibly made your program expect
such output, depending on the form.
Later one day, the Engine changed, still giving exactly mathematically
correct output, but perhaps changing the default format or some other
thing the documentation either explicitly warned may change, or
implicitly did not guarantee not to change, and your program now is no
longer working.
The best advice here would be to tell you how to ask for exactly what
you want, in a way that the system DOES promise to adhere to.
In your case, you could do:
SELECT printf('%0.12f', Rate) AS Rate FROM Customer;
Or whatever similar output format suits you best. You can then make your
program depend on it, because you asked for it to be specifically so,
and the Engine will always give it exactly so, no matter any other
future changes to default formats.

Hope that helps,

Hello SQLite Community Members,
I am facing an issue with SQLite latest version(3.28.0).
SQLITE Return Exponential value in the latest version(3.28.0) rather than
integer number .
The old version (3.6.2) return the same integer value which is inserted .
Below is the screenshots of my sample application which is shown the difference
beween the sqlite 3.6.2 and sqlite 3.28.0.
Sqlite version: 3.28.0
Sqlite version: 3.6.2
The Return Value is different in the both SQLite versions.
- I have downloaded latest SQLite version (3.28.0) from the below link:
https://www.sqlite.org/download.html
- I have downloaded the SQLite version (3.6.2) from the below link:
https://www.sqlite.org/src/info/88c51b9f1579707a
Below is the step how I build the Latest SQlite(3.28.0) Lib:-
-I downloaded the Source code “sqlite-amalgamation-3280000.zip” from the link:
https://www.sqlite.org/download.html
- After that, I build the Visual studio 2012 project name “SQLitelib” from the
downloaded source.(the downloaded source placed in the Project directory.)
- Build the Libarary.
Below is the step how I build the Old SQlite (3.6.2) Lib:-
-I downloaded the Zip file “SQLite-88c51b9f.zip” from the link:
https://www.sqlite.org/src/info/88c51b9f1579707a
- After that,I make “sqlite3.c” from the downloaded source.
-I build the Visual studio 2012 project name “sqlite362” from the source.(the
downloaded Zip file and source placed in the Project directory.)
- Build the Libarary.
Below is the step to Sqlite Test Application:-
-I create sample application in visual studio 2012 app name is “SQLiteCheck”.
-I placed the Both SQLite Lib (Sqlite 3.28.0 abd SQLite 3.6.2) placed in
(ProjectDir)/ Externals folder.
- when the Application Executes.
- Application creates database named “Mydb.db”.
- it will create the table with one column by below SQL Query:
“CREATE TABLE customer(Rate NUMERIC(4) COLLATE BINARY);”
-The it will insert value '.0000439857' by below Query:
“INSERT into customer (Rate) VALUES ('.0000439857')”
-Then it will get the value by below select Query:
“Select Rate from customer”
-Now, Check for “Return value:” it is different for both SQLite versions.
