SQlite Update command problem in Matlab

Hi,all

I do not know why the reason happens when I use command "update" in Matlab to update my SQlite database. The connection 'conn' between Matlab and SQlite database is normal. My PC is on Windows10. The version of Matlab is R2019b.

DatabaseProductName: 'SQLite.

DatabaseProductVersion: '3.30.1'

DriverName: 'SQLite JDBC'

DriverVersion: '3.30.1

rowid username password

1 220171591 220171591

2 admin admin

update(conn,'Login','password',{'ADMIN'},{'WHERE username = ''admin'''})

the mistake matlab give below:

Undefined function 'update' corresponding to input parameters of type 'sqlite'

Is that means anything wrong with my Version of SQlite and Matlab.

Thanks.

seu - is connect valid for SQLite? Try looking at SQLite connection and the available functions (from this page) that can be used to execute SQL statements against STLite databases.

The connect is valid, I can insert and delete in SQlite database

So does a problem only occur when you want to modify a record? What code do you use for those commands that work?

[seu seu]

insert，delete，fetch，but the command 'update' seems do no work to the sqlite database. according to the help docfile, the command 'update' just work for SQL database.

Please type the following into your command window

which update -all

What is returned by the above? It should list all of functions named update. Perhaps there is a conflict.
