在Python或Java或任何高级语言中。dump不起作用。我们需要手工编写转换到CSV的代码。我给出一个Python的例子。其他，例子将会很感激:

from os import path   
import csv 

def convert_to_csv(directory, db_name):
    conn = sqlite3.connect(path.join(directory, db_name + '.db'))
    cursor = conn.cursor()
    cursor.execute("SELECT name FROM sqlite_master WHERE type='table';")
    tables = cursor.fetchall()
    for table in tables:
        table = table[0]
        cursor.execute('SELECT * FROM ' + table)
        column_names = [column_name[0] for column_name in cursor.description]
        with open(path.join(directory, table + '.csv'), 'w') as csv_file:
            csv_writer = csv.writer(csv_file)
            csv_writer.writerow(column_names)
            while True:
                try:
                    csv_writer.writerow(cursor.fetchone())
                except csv.Error:
                    break

如果你有“面板数据”，换句话说，许多带有id的独立条目将this添加到with look中，它还会转储汇总统计数据:

        if 'id' in column_names:
            with open(path.join(directory, table + '_aggregate.csv'), 'w') as csv_file:
                csv_writer = csv.writer(csv_file)
                column_names.remove('id')
                column_names.remove('round')
                sum_string = ','.join('sum(%s)' % item for item in column_names)
                cursor.execute('SELECT round, ' + sum_string +' FROM ' + table + ' GROUP BY round;')
                csv_writer.writerow(['round'] + column_names)
                while True:
                    try:
                        csv_writer.writerow(cursor.fetchone())
                    except csv.Error:
                        break 

您可以为.dump特殊命令指定一个或多个表参数，例如sqlite3 db "。Dump 'table1' 'table2' '”。

伸缩的答案应该是最接近的一个，但它并不适用于我的情况。一个插入查询中途中断，导出就停止了。不知道是什么原因。但是，它在.dump期间工作正常。

最后我写了一个工具来分解.dump生成的SQL:

https://github.com/motherapp/sqlite_sql_parser/

你可以获取.schema和.dump命令的不同。例如，使用grep:

sqlite3 some.db .schema > schema.sql
sqlite3 some.db .dump > dump.sql
grep -vx -f schema.sql dump.sql > data.sql

数据。SQL文件将只包含没有模式的数据，就像这样:

BEGIN TRANSACTION;
INSERT INTO "table1" VALUES ...;
...
INSERT INTO "table2" VALUES ...;
...
COMMIT;

在Python或Java或任何高级语言中。dump不起作用。我们需要手工编写转换到CSV的代码。我给出一个Python的例子。其他，例子将会很感激:

from os import path

def convert_to_csv(directory, db_name):

    cursor = conn.cursor()
    cursor.execute("SELECT name FROM sqlite_master WHERE type='table';")
    tables = cursor.fetchall()
    for table in tables:
        table = table[0]
        cursor.execute('SELECT * FROM ' + table)
        column_names = [column_name[0] for column_name in cursor.description]
        with open(path.join(directory, table + '.csv'), 'w') as csv_file:
            csv_writer = csv.writer(csv_file)
            csv_writer.writerow(column_names)
            while True:
                try:
                    csv_writer.writerow(cursor.fetchone())
                except csv.Error:
                    break

如果你有“面板数据”，换句话说，许多带有id的独立条目将this添加到with look中，它还会转储汇总统计数据:

        if 'id' in column_names:
            with open(path.join(directory, table + '_aggregate.csv'), 'w') as csv_file:
                csv_writer = csv.writer(csv_file)
                column_names.remove('id')
                column_names.remove('round')
                sum_string = ','.join('sum(%s)' % item for item in column_names)
                cursor.execute('SELECT round, ' + sum_string +' FROM ' + table + ' GROUP BY round;')
                csv_writer.writerow(['round'] + column_names)
                while True:
                    try:
                        csv_writer.writerow(cursor.fetchone())
                    except csv.Error:
                        break 

不是最好的方法，但至少不需要外部工具(除了grep，它是*nix盒子上的标准)

sqlite3 database.db3 .dump | grep '^INSERT INTO "tablename"'

但是您确实需要为您正在寻找的每个表执行这个命令。

注意，这不包括模式。
