在Snowflake中,GMT时间字符串通常采用ISO 8601标准的格式,例如"2022-01-01T12:00:00Z"。要将这样的字符串转换为日期格式,可以使用Snowflake的内置函数TO_TIMESTAMP_TZ。 TO_TIMESTAMP_TZ函数接受两个参数:GMT时间字符串和时区。时区可以是具体的时区名称,也可以是时区偏移量。例如,对于GMT时间字符串"2022-01-01...

Snowflake stores all case-insensitive object names in uppercase text. In contrast, SQLAlchemy considers all lowercase object names to be case-insensitive. Snowflake SQLAlchemy converts the object name case during schema-level communication, i.e. during table and index reflection. If you use upper...
String constant stating the type of parameter marker formatting expected by the interface. The connector supports the "pyformat" type by default, which applies to Python extended format codes (e.g. ...WHERE name=%s or ...WHERE name=%(name)s). Connection.connect can override paramstyle to ...

enable the built-in staged copy using an interim Azure Blob storage instance. The staged copy feature also provides you with better throughput. The service automatically converts the data to meet the data format requirements of Snowflake. It then invokes the COPY command to load data into Snow...
