I'm running some queries, that print runtime stats from their execution.
It's done through
print('message')
used within the sql script.
I would want to see these messages while calling the procedures/scripts through pymssql.
conn = pymssql.connect(server, user, password, "tempdb")
cursor = conn.cursor()
cursor.execute("print('message')")
conn.commit()
Above script doesn't return anything, and I can't find any tips on how to get that print to show up in the console output.
Found a solution that let's me still use pymssql and get the print messages.
pymssql.Connection actually uses _mssql.MSSQLConnection internally.
This means that you can use this example by accessing that internal object.
connection = pymssql.connect(server='server_address', database='db_name')
connection._conn.set_msghandler(my_msg_handler) # Install our custom handler
where the my_msg_handler is the same type of object as in pmssql wiki. Accessing internal objects is not ideal, but it's the only way I've found if you don't want to use a different library and need to get the SQL prints.
I don't believe there is a way, but you can refactor your SQL. For example:
DECLARE @my_var AS VARCHAR(200)
PRINT 'Setting a variable...'
SET @my_var = 'this'
PRINT 'I am some output'
SELECT * FROM my_table WHERE this = @my_var
Could be refactored to be something like this:
DECLARE @my_var AS VARCHAR(200)
DECLARE @messages AS VARCHAR(MAX)
SET @messages = @messages + 'Setting a variable...'
SET @my_var = 'this'
SET @messages = @messages + 'I am some output'
SELECT @messages, * FROM my_table WHERE this = @my_var
Good luck!
In order to print something into the console in pymssql, you don't need to put the print inside the execute function. you can simply use
print("message")
so your code will be
conn = pymssql.connect(server, user, password, "tempdb")
cursor = conn.cursor()
print("message")
conn.commit()
