我有一个带有“ Neon”表的数据库。我正在尝试获取与与搜索字符串相关的表“ Neon”关联的所有关键字。
例：
Neon Records:
POLICY_NUM DAYS_TO_BOUND
0170254497 PL Rating
0755698054 PL Rating
1525668307 PL Rating
1525668312 Air
1525668314 Java
1525668356 Sand
而且我有一个搜索字符串
"Save the day by Sand and Java"
我想得到这样的结果
['Sand':'1525668356','Java':'1525668314']
完成的线索正在连接到数据库并提取表数据
import pandas as pd
import logging
import config
from sqlalchemy import create_engine # install mysqlConnector and PyMySql
def db_connection():
"""
:return:
"""
try:
engine = create_engine('mysql+pymysql://{0}:{1}@{2}/{3}'.format(config.database_config['user'],
config.database_config['password'],
config.database_config['host'],
config.database_config['database']))
return engine
except Exception as e:
logging.info(e)
finally:
pass
def extract_table(query):
"""
:param query:
:return:
"""
engine = db_connection()
sql_select_query = query
details = pd.read_sql(sql_select_query, engine)
return details
database_query = {
'select_query_for_data': 'select * from Neon'
}
请让我知道您对此的想法。
您在找这个吗？
DECLARE @DataSource TABLE
(
[POLICY_NUM] VARCHAR(16)
,[DAYS_TO_BOUND] VARCHAR(16)
);
INSERT INTO @DataSource ([POLICY_NUM], [DAYS_TO_BOUND])
VALUES ('0170254497', 'PL Rating')
,('0755698054', 'PL Rating')
,('1525668307', 'PL Rating')
,('1525668312', 'Air')
,('1525668314', 'Java')
,('1525668356', 'Sand');
DECLARE @DataString VARCHAR(4000) = 'Save the day by Sand and Java';
DECLARE @DataStringXML XML = '<a>' + REPLACE(@DataString, ' ', '</a><a>') + '</a>';
WITH DataSource ([rowID], [rowValue]) AS
(
SELECT ROW_NUMBER() OVER (ORDER BY T.c ASC)
,T.c.value('.', 'VARCHAR(256)')
FROM @DataStringXML.nodes('a') T(c)
)
SELECT '[' + STUFF
(
(
SELECT ',' + '''' + V.[rowValue] + ''':''' + D.[POLICY_NUM] + ''''
FROM DataSource V
INNER JOIN @DataSource D
ON V.[rowValue] = D.[DAYS_TO_BOUND]
ORDER BY V.[rowID]
FOR XML PATH(''), TYPE
).value('.', 'VARCHAR(MAX)')
,1
,1
,''
) + ']'
它产生：
['Sand':'1525668356','Java':'1525668314']
