CREATE TAG IF NOT EXISTS person(`_createTime` STRING,`specific_type` STRING,`key` STRING,`edges` STRING,`name` STRING)

error message

SyntaxError: syntax error near ``_create'

Sorry @Freeself

It's either not parsed properly or it's not supported (then we should have documented that) the underline cannot be in starting position.

(root@nebula) [basketballplayer]> CREATE TAG IF NOT EXISTS person(`createTime` STRING,`specific_type` STRING,`key` STRING,`edges` STRING,`name` STRING)
Execution succeeded (time spent 3066/45961 us)

Thanks!

@czpmango could you kindly help confirm if this is should be documented(as naming constraint) or fixed(that a prop name starts with _)?

The subsequent implementation will not be changed, and the variable naming rules follow the regular expression ([A-za-z][_A - za-z0-9]*).
