Error 1065 'query was empty' in the python script

+1 vote
468 views

I have kept all the create table SQL querys in a text file. Using readLines i am trying to execute the sql commands as per the code mentioned.

file=open("TABLES.txt","r")
for sql in file.readlines():
self.cursor.execute(sql)

But I am getting Error 1065 ' Query was empty'. More Importantly the tables are being created in the database. The text file is like this.

CREATE TABLE TUserDetails (FirstName VarChar(50) NOT NULL, LastName VarChar(50) NOT NULL, Email_Id VarChar(50) NOT NULL,Type VarChar(50) NOT NULL,Department VarChar(50) NOT NULL,NoOfIncorrectAttempt Integer NOT NULL,Deleted Bit NOT NULL,UserID VarChar(50) NOT NULL,CONSTRAINT TUserDetails_PK PRIMARY KEY CLUSTERED ( UserID ))

CREATE TABLE TRequests(RequestID VarChar(50) NOT NULL,UserID VarChar(50) NOT NULL,Status SmallInt NOT NULL,TimeOfRequest Timestamp NOT NULL,Deleted Bit NOT NULL,Priority Integer NOT NULL,CONSTRAINT TRequests_PK PRIMARY KEY CLUSTERED ( RequestID ))

CREATE TABLE TUserDetailUSERs(UserID VarChar(50) NOT NULL, Type VarChar(50) NOT NULL,Deleted Bit NOT NULL,TimeOfCreation Timestamp NOT NULL,TimeLastUpdated Timestamp NOT NULL,Active Bit NOT NULL,PWDID VarChar(50) NOT NULL,RoleID VarChar(50) NOT NULL,OrganisationID Integer NOT NULL,CONSTRAINT TUserDetailUSERs_PK PRIMARY KEY CLUSTERED ( UserID ))

CREATE TABLE TOrganisations(OrganisationID Integer NOT NULL,OrganisationName VarChar(50) NOT NULL,TimeOfCreation Timestamp NOT NULL,TimeLastUpdated Timestamp NOT NULL, Deleted Bit NOT NULL, CONSTRAINT TOrganisations_PK PRIMARY KEY CLUSTERED ( OrganisationID ))

CREATE TABLE TPWDs(PWDID VarChar(50) NOT NULL,Code VarChar(50) NOT NULL,DateOfCreation Timestamp NOT NULL,DateLastUpdated Timestamp NOT NULL,TimeOfDeletion Timestamp NOT NULL, CONSTRAINT TPWDs_PK PRIMARY KEY CLUSTERED ( PWDID ))

CREATE TABLE TRoles(RoleID VarChar(50) NOT NULL,RoleName VarChar(50) NOT NULL,Description VarChar(50) NOT NULL,TimeOfCreation Timestamp NOT NULL, RoleLastUpdated VarChar(50) NOT NULL, Deleted Bit NOT NULL, CONSTRAINT TRoles_PK PRIMARY KEY CLUSTERED ( RoleID ))

I checked running each sql query individually, and it is qorking file. Now although the tables are being created in the database but i am getting error 1065 as mentioned above

Confused with the question are u using mysql or sql server, question is tagged as mysql and sqlserver both.

More importantly there are two question with similar content, can you clarify which is correct i.e this one or http://tech.queryhome.com/35942/mysql-error-1065-query-was-empty

Waiting for your response.
IT's MySQL. Sorry for tagging SQLServer
Please Help.....I already saw all the google links and posted it here
You are creating six tables so you must be getting "query was empty" six times. Please cross check in case you are receiving only one then one of the script is failing or mat be null at the end or something similar.
No, I am getting 'query was empty' only once. So according to you one script is failing? Can u please give me possible errors or mistakes which i am making.
OK, now narrow down which one is failing may be adding a print may tell which one is failing.
Now once we narrow down which one is failing it would be easy to debug...
I figured out what is the problem. It happening when reading the last line...Empty line...Now i am not getting how to check for empty line.
I used len(sql)==0, sql==""  sql[0]="\n" len(sql)==2 assuming "\n\r" as empty line. But none is working.
cool that's what I pointed out, anyway try to check the length of the string if it is zero or not...
Thanks Now it's working fine.
Another question is:
why  my code is giving warning for each sql query as mentioned above??
Warning (from warnings module):
  File "C:\Python27\CreateDatabase.py", line 21
    self.cursor.execute(sql)
Warning: Unknown table 'tuserdetails'

Warning (from warnings module):
  File "C:\Python27\CreateDatabase.py", line 21
    self.cursor.execute(sql)
Warning: Unknown table 'trequests'
and so on

Salil u may have missed -
There may be blank lines between the SQL statements and that may be the reason of Prakash is getting the 1065. Its a common problem.

What is the proper way in which I can execute dynamic MySQL queries in Python? I want to do dynamic queries for both CREATE and INSERT statement.
Here is my attempted code:

sql="create table %s (%%s, %%s, %%s ... )" % (tablename,''.join(fields)+' '.join(types))
cur.execute(sql) 

where 'field' is the fieldnames stored in a list and 'types' are the fieldtypes stored in a list.

I am using Python 2.7, MySQl 5.5, mysqldb(driver) and trying to connect to the mysql db using Python.

What I have tried

import MySQLdb
db = MySQLdb.connect(host="localhost",
                     user="root", # username
                      passwd="xxxxx", #  password
                      db="TEST") # name of the data base

Even tried 127.0.0.1 as local host

#ERROR
Traceback (most recent call last):
  File "C:/Python27/connect.py", line 6, in <module>
    db="prakash") # name of the data base
  File "C:\Python27\lib\site-packages\MySQLdb\__init__.py", line 81, in Connect
    return Connection(*args, **kwargs)
  File "C:\Python27\lib\site-packages\MySQLdb\connections.py", line 187, in __init__
    super(Connection, self).__init__(*args, **kwargs2)
  OperationalError: (2003, "Can't connect to MySQL server on 'localhost' (10061)")

I am new to python, please help how to proceed?
