Question

我用python编写了一个程序，将读取的信息写到sqlite数据库。

我想逐行读取txt文件，当读取某些特定单词时，应在sql数据库中添加相应的值1。

但是当我使用更新方法时，会出现错误：“，”附近：语法错误。

    conn = sqlite3.connect(fname + '\\Static_Analysis.db')

    print fname + 'Static_Analysis.db'

    c = conn.cursor()
    c.execute('''CREATE TABLE MAIN
           (
           FOLDER_NAME           TEXT    NOT NULL,
           FILE_NAME             TEXT    NOT NULL,
           Error_NO          integer,
           Warning_NO         integer,
           Advice_NO          integer,
           Total          integer,
           Note           CHAR(50),
           PRIMARY KEY (FOLDER_NAME, FILE_NAME ));''')

    c.execute('''CREATE TABLE ERROR_REPORT
           (
           NAME           TEXT    NOT NULL,
           PRIMARY KEY (NAME));''')

    c.execute('''CREATE TABLE WARNING_REPORT
           (
           NAME           TEXT    NOT NULL,

    for dst in list:

像这样替换您的插入语句：

con sqs

您无需指定类型，仅使用conn.execute("""INSERT INTO MAIN (FOLDER_NAME, FILE_NAME, Error_NO, Warning_NO, Advice_NO, Total, Note) VALUES(%s, %s, %s, %s, %s, %s, %s)""" % (dst, str[0][9:], 0, 0, 0, 0, '')) python即可正确处理它。但是请确保您提供的参数值与表中的值一致。

您的更新还：

%s

您的conn.execute("""UPDATE MAIN SET Error_NO = Error_NO + 1, Total = Total + 1 WHERE FOLDER_NAME= %s and FILE_NAME = %s """ % (dst, str[0][9:]))子句应为where或WHERE FOLDER_NAME= %s and FILE_NAME = %s，并且不能带逗号。
