python 2.7 - mysql.connector, multi=True, sql variable assignment not working -


sql code (all in 1 file saved in python variable "query"):

select @dtmax:=date_format(max(dt), '%y%m') table_a; delete table_b  date_format(dt, '%y%m')=@dtmax; 

does mysql-connector allow use of variable assignment i've done in query above. i.e. take value of max(date) table_a , delete date table_b.

python code:

    c = conn.cursor(buffered=true)     c.execute(query, multi=true)     conn.commit()     conn.close() 

all know 2nd sql statement doesnt execute.

i can copy , paste sql code toad , run there without problems not through mysql.connector library. have used pandas legacy script written else , don't have time re-write everything.

i kindly appreciate help.

when use multi=true, execute() return generator. need iterate on generator advance processing next sql statement in multi-statement query:

c = conn.cursor(buffered=true) results = c.execute(query, multi=true) cur in results:     print('cursor:', cur)     if cur.with_rows:         print('result:', cur.fetchall()) conn.commit() conn.close() 

cur.with_rows true if there results fetch current statement.

this describend in documentation of mysqlcursor.execute()
