As we can see in the snowflake docs the COLLATE statement requires single quotes for the collation specification.
In case of running CREATE TABLE script with double quotes in the Snowflake Console it returns the result like
SQL compilation error: syntax error line 3 at position 24 unexpected '"SQL_Latin1_General_CP1_CI_AS"'.
After this PR
sqlalchemy.schema.CreateTable(some_table).compile
withdialect=snowflake.sqlalchemy.snowdialect.dialect()
will return i.e.name NCHAR(10) COLLATE 'SQL_Latin1_General_CP1_CI_AS'
instead ofname NCHAR(10) COLLATE "SQL_Latin1_General_CP1_CI_AS"
This PR just overriding _render_string_type method from SQLAlchemy GenericTypeCompiler class for Snowflake SQLAlchemy dialect.
Tested with Python 3.8.2
