Is there any reason why Spark SQL supports "<column name>" ":" "<data
type>" while specifying columns ? eg. sql("CREATE TABLE t1 (column1:INT)")
works fine.
Here is relevant snippet in the grammar [0]:
```
colType
: identifier ':'? dataType (COMMENT STRING)?
;
```
I do not see MySQL[1], Hive[2], Presto[3] and PostgreSQL [4] supporting ":"
while specifying columns. They all use space as a delimiter.
