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.
```ngql nebula> CREATE SPACE IF NOT EXISTS my_space (vid_type=FIXED_STRING(30)); nebula> use MY_SPACE;
```
Keywords and Reserved Words are Case-Insensitive¶
The following statements are equivalent since show and spaces are keywords.
ngql
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.
ngql
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 |
+----------+----------+-------------------+
