如何修复Snowflake数据库写入错误：Snowflke.Connector.errors.ProgrammingError)001003(42000)

问题描述

ProgrammingError: (snowflake.connector.errors.ProgrammingError) 001003 (42000): SQL compilation error:
syntax error line 1 at position 13 unexpected 'sample'. [SQL: '
CREATE TABLE sample (
	"Business Address" TEXT
)

'] (Background on this error at: http://sqlalche.me/e/f405)

已安装必要的程序包：pip install --upgrade snowflake-sqlalchemy

from sqlalchemy import create_engine
engine = create_engine(
    'snowflake://{user}:{password}@{account}/SAMPLE_WORK/public?warehouse=****&role=myrole'.format(user='***',password='****',account='*****') 
)

df.to_sql('sample', engine, if_exists='replace', index=False)

推荐答案

SAMPLE is a reserved keyword在雪花(和Sql：2003)中，但snowflake-sqlalchemy方言似乎没有正确引用。一个捷径是将其注入保留字集合：

# Before creating the engine etc.
from snowflake.sqlalchemy.base import SnowflakeIdentifierPreparer
# The set uses lower case, though the source set upper.
SnowflakeIdentifierPreparer.reserved_words.add("sample")
