python库，用于从SQL语句中的子句中提取表名

Question

我有一个复杂的SQL如下。我正在寻找一个python(3+)库，可以提取从子句中包含的表名称。我正在映射客户端的数据库&的观点,报告，并且有几十个查询要映射，因此需要自动化作业。

已经看了Python-sqlparse, sqlparse，但我不确定他们是否能完成任务，我试图避免学习曲线

Answer 1

我创建了Sqlglot，它可以解析你的SQL。

import sqlglot
import sqlglot.expressions as exp
expression = sqlglot.parse_one(..., read=“oracle”)
list(expression.find_all(exp.Table))

Answer 2

您可以将sqlparse与递归生成器函数一起使用:

import sqlparse, re
def get_tables(d):
f = False
for i in getattr(d, 'tokens', []):
if isinstance(i, sqlparse.sql.Token) and i.value.lower() == 'from':
f = True
elif isinstance(i, (sqlparse.sql.Identifier, sqlparse.sql.IdentifierList)) and f:
f = False
if not any(isinstance(x, sqlparse.sql.Parenthesis) or 'select' in x.value.lower() for x in getattr(i, 'tokens', [])):
fr = ''.join(str(j) for j in i if j.value not in {'as', 'n'})
for t in re.findall('(?:w+.w+|w+)s+w+|(?:w+.w+|w+)', fr):
yield {'table':(t1:=t.split())[0], 'alias':None if len(t1) < 2 else t1[-1]}
yield from get_tables(i)
print(list(get_tables(sqlparse.parse(s)[0])))

输出:
