Review Comment:
This table has schema equivalent to doing the following (note the `"` are
very important as they say to not normalize case):
```sql
CREATE TABLE test(
"Column1" varchar,
"COLUMN2" varchar,
"column3" varchar
)
```
And in that case, I would expect
```sql
"SELECT COLumn1, colUMN2, column3 FROM test WHERE TEst.COLUMN1='content1'
and column2='content2' and COLumn3='content3'"
```
to fail
