ISSUE: https://github.com/FirebirdSQL/firebird/issues/6416
|
||||
TITLE: Engine cant determine datatype in SQL: Unknown SQL Data type (32752) [CORE6168]
|
||||
DESCRIPTION:
|
||||
Test creates table with columns belonging to "new datatypes" family: int128, decfloat and time[stamp] with time zone.
|
||||
Also, one record is added into this table with values which are valid for numeric types in FB 4.x+ (time zone fields
|
||||
can remain null or arbitrary).
|
||||
This DB is them copied to another DB (using file-level call of shutil.copy2()).
|
||||
Another DB filename must match to the specified in the databases.conf (alias defined by 'REQUIRED_ALIAS' variable).
|
||||
Its alias has special value for DataTypeCompatibility parameter. Connection to this DB and query to a table with 'new datatypes'
|
||||
must return SQLDA with *old* types which are known for FB versions prior 4.x.
|
||||
|
||||
Then we repeat same query to 'initial' test DB and must get SQLDA with actual values for all new columns (known since FB 4.x).
|
||||
NOTES:
|
||||
[18.08.2022] pzotov
|
||||
1. One need to be sure that firebird.conf does NOT contain DatabaseAccess = None.
|
||||
2. Database file for REQUIRED_ALIAS must NOT exist in the QA_root/files/qa/ subdirectory: it will be created here.
|
||||
Content of databases.conf must be taken from $QA_ROOT/files/qa-databases.conf (one need to replace
|
||||
it before every test session).
|
||||
Discussed with pcisar, letters since 30-may-2022 13:48, subject:
|
||||
"new qa, core_4964_test.py: strange outcome when use... shutil.copy() // comparing to shutil.copy2()"
|
||||
3. Value of REQUIRED_ALIAS must be EXACTLY the same as alias specified in the pre-created databases.conf
|
||||
(for LINUX this equality is case-sensitive, even when aliases are compared!)
|
||||
|
||||
Checked on 6.0.0.438, 5.0.2.1479, 4.0.6.3142.
