Identifier case sensitivity

Identifiers are Case-Sensitive

The following statements will not work because they refer to two different spaces, i.e. my_space and MY_SPACE.

nebula> CREATE SPACE IF NOT EXISTS my_space (vid_type=FIXED_STRING(30));
nebula> use MY_SPACE;
[ERROR (-8)]: SpaceNotFound:

Keywords and Reserved Words are Case-Insensitive

The following statements are equivalent since show and spaces are keywords.

nebula> show spaces;  
nebula> SHOW SPACES;
nebula> SHOW spaces;
nebula> show SPACES;

Functions are Case-Insensitive

Functions are case-insensitive. For example, count(), COUNT(), and couNT() are equivalent.

nebula> WITH [NULL, 1, 1, 2, 2] As a \
        UNWIND a AS b \
        RETURN count(b), COUNT(*), couNT(DISTINCT b);
+----------+----------+-------------------+
| count(b) | COUNT(*) | couNT(distinct b) |
+----------+----------+-------------------+
| 4        | 5        | 2                 |
+----------+----------+-------------------+
