Méthode mariadb.Cursor.fetchmany

Signature de la méthode fetchmany

def fetchmany(self, size: int = 0) 

Description

help(Cursor.fetchmany)

Fetch the next set of rows of a query result, returning a sequence
of sequences (e.g. a list of tuples). An empty sequence is returned
when no more rows are available.

The number of rows to fetch per call is specified by the parameter.
If it is not given, the cursor's arraysize determines the number
of rows to be fetched. The method should try to fetch as many rows
as indicated by the size parameter.
If this is not possible due to the specified number of rows not being
available, fewer rows may be returned.

An exception will be raised if the previous call to execute() didn't
produce a result set or execute() wasn't called before.
