if somebody is experiencing same errors in first steps with pyramid and ms sql server: I found the reason for "Pyramid is having a problem using your SQL database" SqlAlchemy tried to execute:
SELECT TOP 1 models.id AS models_id, models.name AS models_name, models.value AS models_value FROM models WHERE models.name = 'one' and got error : "The data types text and varchar are incompatible in the equal to operator" When I changed column "models.name" type from "text" to "nvarchar" it works my second question for legacy tables is still open for help :-) Dana srijeda, 1. listopada 2014. 22:08:37 UTC+2, korisnik Alen Cerovic napisao je: > thnx pb, made it partially working, after initialize_MyApp_db which > successfully created "models" table I still get error in browser "Pyramid > is having a problem using your SQL database" > > another question: how to define models for existing database tables and > tell pyramid not to alter my existing tables > > Dana srijeda, 1. listopada 2014. 20:04:42 UTC+2, korisnik pb napisao je: > >> Hi, >> >> I have 32bit python 2.7, 32 bit windows, pyodbc 3.0.6, and sqlalchemy >> 0.8, and my connection string >> is something like: >> >> mssql://username:password@hostname/dbname?driver=SQL Server Native Client >> 10.0;unicode_results=True >> >> where driver=... is the same text I found in the ODBC data source >> administrator on the tab Drivers. >> >> I didn't need any pymssql, as pyodbc uses odbc drivers.
