from simplesqlite.query import Where


table_name = "sample_table"
con = SimpleSQLite("sample.sqlite", "w")

data_matrix = [
    [1, "aaa"],
    [2, "bbb"],
]
con.create_table_from_data_matrix(
    table_name,
    ["key", "value"],
    data_matrix)

print("---- before update ----")
for record in con.select(select="*", table_name=table_name).fetchall():
    print(record)
print()

con.update(table_name, set_query="value = 'ccc'", where=Where(key="key", value=1))

print("---- after update ----")
for record in con.select(select="*", table_name=table_name).fetchall():
    print(record)

Output:

---- before update ----

---- after update ----
(1, 'ccc')
