- -- source include/have_innodb.inc
- --disable_warnings
- drop table if exists t1;
- --enable_warnings
- connect (con1,localhost,root,,);
- connect (con2,localhost,root,,);
- ### Test 1:
- ### - While a consistent snapshot transaction is executed,
- ### no external inserts should be visible to the transaction.
- connection con1;
- create table t1 (a int) engine=innodb;
- start transaction with consistent snapshot;
- connection con2;
- insert into t1 values(1);
- connection con1;
- select * from t1; # if consistent snapshot was set as expected, we
- # should see nothing.
- commit;
- ### Test 2:
- ### - For any non-consistent snapshot transaction, external
- ### committed inserts should be visible to the transaction.
- delete from t1;
- start transaction; # Now we omit WITH CONSISTENT SNAPSHOT
- connection con2;
- insert into t1 values(1);
- connection con1;
- select * from t1; # if consistent snapshot was not set, as expected, we
- # should see 1.
- commit;
- drop table t1;
- # End of 4.1 tests
