Description
CREATE TABLE `table1` (
|
`id` int(11) DEFAULT NULL, |
`name` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT NULL |
) ENGINE=Aria DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci PAGE_CHECKSUM=1; |
|
CREATE TABLE `table2` (
|
`id` int(11) DEFAULT NULL, |
`name` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT NULL |
) ENGINE=Aria DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci PAGE_CHECKSUM=1; |
|
CREATE TRIGGER `table1_before_insert` BEFORE INSERT ON `table1`
|
FOR EACH ROW BEGIN
|
insert into table2(`id`, `name`) values (NEW.`id`, NEW.`name`);
|
END
|
import mariadb |
conn=mariadb.connect(user="test", database="test") |
cursor=conn.cursor()
|
vals = [(1,'John'), (2,'Smith'), (3,'Carol')] |
cursor.executemany("INSERT INTO table1 VALUES (?,?)", vals) |
cursor.execute("SELECT * FROM table1") |
rows= cursor.fetchall()
|
print(rows)
|
Expected output:
[(1, 'John', 1, 'John'), (2, 'Smith', 1, 'John'), (3, 'Carol', 1, 'John'), (1, 'John', 2, 'Smith'), (2, 'Smith', 2, 'Smith'), (3, 'Carol', 2, 'Smith'), (1, 'John', 3, 'Carol'), (2, 'Smith', 3, 'Carol'), (3, 'Carol', 3, 'Carol')]
Current output:
[(1, 'John', 1, 'John'), (1, 'John', 1, 'John')]
Expected rows on tables:
Table1:
"1" "John"
"2" "Smith"
"3" "Carol"
Table2:
"1" "John"
"2" "Smith"
"3" "Carol"
Current rows on tables:
Table1:
"1" "John"
Table2:
"1" "John"
"1" "John"
Running insert on mariadb console, works correctly:
insert into Table1 values(1,'John'),(2,'Smith'),(3,'Carol');
