sql - Syntax error while fetching table list from teradata using python

Question

For learning purpose, I am trying to fetch table list from Teradata in Python with the following code:

import jaydebeapi
import pandas as pd

try:
   conn = jaydebeapi.connect(jclassname='com.teradata.jdbc.TeraDriver',
                                      url="jdbc:teradata://10.10.10.10",
                                      driver_args=['@user','@pss'],
                                      jars=['/mnt/TERADATA/tdgssconfig.jar','/mnt/TERADATA/terajdbc4.jar'])

   print("Connection was successful")
except Exception as e:
        print(e)

 #df = pd.read_sql_query('SELECT Databasename,TableName FROM dbc.tables WHERE tablekind = \'T\'',conn)
  dfr = pd.DataFrame(df)
  print(dfr.head(3))

The above works fine but when I try to fetch the table list based on a Database name then things are not working:

 df = pd.read_sql_query('SELECT Databasename,TableName FROM dbc.tables WHERE tablekind = \'T\' and DatabaseName ='SALES'',conn)
 dfr = pd.DataFrame(df)
 print(dfr.head(3))

getting:

Error: Invalid Syntax

It has been couple of hours trying to figure it out but not able to get through it. Its very stupid to ask this but please advice where am I going wrong.

Answer 1

也许这只是一个 Python 语法的东西。我希望：

df = pd.read_sql_query("""SELECT Databasename, TableName FROM dbc.tables WHERE tablekind = 'T' and DatabaseName = 'SALES'""", conn)

正如您所写的，它SALES在字符串之外，无疑会导致语法错误。
