"""Empty Identifier Validation Test
|
|
|
|
Test empty identifier `` handling in 28 specific SQL statements and verify error code -2147473897:
|
|
|
|
1. Test [Table Operations] with Empty Identifiers
|
|
1.1 show create table `` - verify error -2147473897
|
|
1.2 show create table test.`` - verify error -2147473897
|
|
1.3 create table `` (ts timestamp, c1 int) - verify error -2147473897
|
|
1.4 drop table `` - verify error -2147473897
|
|
1.5 alter table `` add column c2 int - verify error -2147473897
|
|
1.6 select * from `` - verify error -2147473897
|
|
|
|
2. Test [Column and Tag Operations] with Empty Identifiers
|
|
2.1 alter table meters add column `` int - verify error -2147473897
|
|
2.2 alter table meters drop column `` - verify error -2147473897

|
2.3 alter stable meters add tag `` int - verify error -2147473897

2.4 alter stable meters rename tag cc `` - verify error -2147473897
|
|
2.5 alter stable meters drop tag `` - verify error -2147473897

|
|
3. Test [Data Manipulation] with Empty Identifiers
|
|
3.1 insert into `` select * from t0 - verify error -2147473897
|
|
3.2 insert into t100 using `` tags('', '') values(1,1,1) - verify error -2147473897

4. Test [View Operations] with Empty Identifiers
|
|
4.1 create view `` as select count(*) from meters interval(10s) - verify error -2147473897
|
|
4.2 create view ``.view1 as select count(*) from meters - verify error -2147473897

4.4 drop view ``.st1 - verify error -2147473897

5. Test [TSMA Operations] with Empty Identifiers
|
|
5.1 create tsma `` on meters function(count(c1)) interval(1m) - verify error -2147473897
|
|
5.2 create tsma tsma1 on `` function(count(c1)) interval(1m) - verify error -2147473897
|
|
|
|
6. Test [Stream Operations] with Empty Identifiers
|
|
6.1 create stream `` interval(10s) sliding(10s) from meters into st1 as select count(*) from meters - verify error -2147473897
|
|
6.2 create stream stream1 interval(10s) sliding(10s) from meters into `` as select count(*) from meters - verify error -2147473897
|
|
6.3 create stream stream1 interval(10s) sliding(10s) from meters into st1 as select count(*) from `` - verify error -2147473897

6.4 create stream stream1 interval(10s) sliding(10s) from meters stream_options(max_delay(100s)) into st1 as select count(*) from `` - verify error -2147473897

6.5 create stream stream1 interval(10s) sliding(10s) from `` stream_options(max_delay(100s)) into st1 as select count(*) from meters - verify error -2147473897
|
|
|
|
7. Test [Topic Operations] with Empty Identifiers
|
|
7.1 create topic `` as select count(*) from meters interval(10s) - verify error -2147473897
|
|
7.2 drop topic `` - verify error -2147473897
|
|
|
|
8. Test [Error Code Verification] for All Cases
|
|
8.1 Execute all 28 SQL statements with empty identifiers
|
|
8.2 Verify each returns exact error code -2147473897
|
|
8.3 Confirm error message consistency
|
|
8.4 Validate connection stability after errors
