For sql_select_query = 'select * from table', you can use pymysql python module to connect to MySql database and cursor.description to extract values.
def conn():
myDb=pymysql.connect(server,user,password,database)
return myDb
dbc = conn() #database connection
dbCursor = dbc.cursor() # cursor
# gathers all column field names and their type
field_names_and_type = [desc[:2] for desc in dbCursor.description]
Example output:
print(field_names_and_type)
[('ItemId', 1), ('ItemName', 3)]
type 1 is nvchar
type 3 is int
Question: how to i map these? I've checked pymysql docs but could not find the mapping for cursor.description output.
