sqlalchemy.exc.ProgrammingError: (pymysql.err.ProgrammingError) (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'fromt_user' at line 1")

報錯是這樣的，意思就是我的sql語法出錯了

今天在弄pandas連接mysql數(shù)據(jù)庫的時候，最后運行時出錯了

源代碼：

from sqlalchemy import create_enginedef query(table):host = 'localhost'user = 'root'password = '123456'database = 'ConstructionDB'port = 3306conn = create_engine('mysql+pymysql://{}:{}@{}:{}/{}'.format(user, password, host, port, database))sql = 'select * from' + tableresults = pd.read_sql(sql, conn)return results

通過debug發(fā)現(xiàn)，原來sql語句在拼接的時候沒有空格，導致sql最后的語法時

sql = [select * fromt_user]

沾一塊去了

def query(table):host = 'localhost'user = 'root'password = '123456'database = 'ConstructionDB'port = 3306conn = create_engine('mysql+pymysql://{}:{}@{}:{}/{}'.format(user, password, host, port, database))sql = 'select * from' +' ' + tableresults = pd.read_sql(sql, conn)return results

注意?sql語句?，把代碼中間? 拼接一個空格? 即可，問題解決
