sqlite3.OperationalError：靠近「CSV1」：語法錯誤

Question

嗨，我有這樣的Python腳本。我在Python版本3.4.2中運行它。

import csv 
import sqlite3 

def createTable(cursor, rows, tablename): 
    tableCreated = False 
    for row in rows: 
     if not tableCreated: 
      sql = "CREATE TABLE %s(ROW INTEGER PRIMARY KEY, " + ", ".join(["c%d" % (i+1) for i in range(len(row))]) + ")" 
      cur.execute(sql % tablename) 
      tableCreated = True 
     sql = "INSERT INTO %s VALUES(NULL, " + ", ".join(["'" + c + "'" for c in row]) + ")" 
     cur.execute(sql % tablename) 
    conn.commit() 


conn = sqlite3.connect(":memory:") 
cur = conn.cursor() 

for filename, tablename in [("in1.csv", "CSV1"), ("out1.csv", "CSV2")]: 
    with open(filename, "r") as f: 
     reader = csv.reader(f, delimiter=',') 
     rows = [row for row in reader] 
    createTable(cur, rows, tablename) 

sql = """WITH 
MATCHES AS(SELECT  CSV2.* 
       , CSV1.ROW as ROW_1     
       , CSV1.C4 as C4_1 
       , CSV1.C5 as C5_1 
    FROM  CSV2 
    LEFT JOIN CSV1 
    ON   CSV1.C4 LIKE '%' || CSV2.C2 || '%'  
), 
EXACT AS(CSV1.C4 = CSV1.C5 
    SELECT  * 
    FROM  MATCHES 
    WHERE  C4_1 = C5_1 
), 
MIN_ROW AS(SELECT  C1 
       , min(ROW_1) as ROW_1 
    FROM  MATCHES 
    WHERE  C1 NOT IN (SELECT C1 FROM EXACT) 
    GROUP BY C1, C2, C3, C4, C5     
) 
SELECT  * 
FROM  EXACT 
UNION 
SELECT  MATCHES.* 
FROM  MIN_ROW 
INNER JOIN MATCHES 
ON   MIN_ROW.C1 = MATCHES.C1 
AND   (MIN_ROW.ROW_1 = MATCHES.ROW_1 OR MIN_ROW.ROW_1 IS NULL) 
ORDER BY C1""" 
for row in cur.execute(sql): 
    print (row) 

運行此腳本給我

Traceback (most recent call last): 
    File "script.py", line 55, in <module> 
    for row in cur.execute(sql): 
sqlite3.OperationalError: near "CSV1": syntax error 

我一直對這個劇本相當長的一段時間了，我完全失去了。我真的很感激，如果有人能通過一個工作腳本讓我擺脫這個困境。請找到下面的示例CSV文件。

數據庫抱怨在EXACT定義多餘CSV1.C4 = CSV1.C5。
