Question

我寫了這個程序：

con=kinterbasdb.create_database("create database 'D:/ThirdTask/test.db' user 'sysdba' password 'masterkey'") 
conn=kinterbasdb.connect(host='localhost',database='D:/ThirdTask/test.db', user='sysdba', password='masterkey') 
cur=con.cursor() 
s=""" 
create table CLIENTS 
    (  
    ID FMTBCD PRIMARY KEY, 
    COMPANY CHAR(50), 
    LAST NAME CHAR(50), 
    FIRST NAME CHAR(50), 
    E-MAIL ADDRESS CHAR(50), 
    JOB TITLE CHAR(50), 
    BUSINESS PHONE CHAR(25), 
    HOME PHONE CHAR(25), 
    MOBILE PHONE CHAR(25), 
    FAX NUMBER CHAR(25), 
    ADDRESS MEMO, 
    CITY CHAR(50), 
    STATE/PROVINCE CHAR(50), 
    ZIP/POSTAL CODE CHAR(15), 
    COUNTRY/REGION CHAR(50), 
    WEB-SITE CHAR(25), 
    NOTES MEMO, 
    INCLUDING BLOB 
    )""" 
    print s 
    cur.execute(s) 
    con.close() 
    conn.close() 

編譯器給出了以下錯誤：

create table CLIENTS 
(
    ID FMTBCD PRIMARY KEY, 
    COMPANY CHAR(50), 
    LAST NAME CHAR(50), 
    FIRST NAME CHAR(50), 
    E-MAIL ADDRESS CHAR(50), 
    JOB TITLE CHAR(50), 
    BUSINESS PHONE CHAR(25), 
    HOME PHONE CHAR(25), 
    MOBILE PHONE CHAR(25), 
    FAX NUMBER CHAR(25), 
    ADDRESS MEMO, 
    CITY CHAR(50), 
    STATE/PROVINCE CHAR(50), 
    ZIP/POSTAL CODE CHAR(15), 
    COUNTRY/REGION CHAR(50), 
    WEB-SITE CHAR(25), 
    NOTES MEMO, 
    INCLUDING BLOB 
    ) 

Traceback (most recent call last): 
File "D:\ThirdTask\connect.py", line 119, in <module> 
     cur.execute(s) 
ProgrammingError: (-104, 'isc_dsql_prepare: \n Dynamic SQL Error\n SQL error code = -104\n Token unknown - line 6, column 16\n CHAR') 

可能是什麼錯誤的原因是什麼？

Answer 1

您正在使用空格定義列名以及使用-破折號和\斜槓。把這樣的名字在雙引號：

s=""" 
create table CLIENTS 
    (  
    ID FMTBCD PRIMARY KEY, 
    COMPANY CHAR(50), 
    "LAST NAME" CHAR(50), 
    "FIRST NAME" CHAR(50), 
    "E-MAIL ADDRESS" CHAR(50), 
    "JOB TITLE" CHAR(50), 
    "BUSINESS PHONE" CHAR(25), 
    "HOME PHONE" CHAR(25), 
    "MOBILE PHONE" CHAR(25), 
    "FAX NUMBER" CHAR(25), 
    ADDRESS MEMO, 
    CITY CHAR(50), 
    "STATE/PROVINCE" CHAR(50), 
    "ZIP/POSTAL CODE" CHAR(15), 
    "COUNTRY/REGION" CHAR(50), 
    "WEB-SITE" CHAR(25), 
    NOTES MEMO, 
    INCLUDING BLOB 
    )"""
