## Actual output
```sql
CREATE TABLE "t2"("b","c","_ROWID_",PRIMARY KEY("b","c","_ROWID_"))WITHOUT ROWID;
WARNING: writing to an imposter table will corrupt the "t1bc" index!
Braun|30|3
Wernher|10|1
von|20|2
Braun|30
Wernher|10
von|20
```
## Expectation
```sql
CREATE TABLE "t2"("b","c","_ROWID_",PRIMARY KEY("b","c","_ROWID_"))WITHOUT ROWID;
Braun|30|3
Wernher|10|1
von|20|2
Braun|30
Wernher|10
von|20
```
