The Type number is not qualified with a namespace or alias.

[anand123]

I am working on DevArt Oracle Connect PoC for our existing application. Our application suppose to work in sql and oracle using EF. So we have two sets of (SSDL, CSDL, MSL) for oracle and sql. Now I am trying to use same oracle specific files with DevArt. Getting below error. we have few config settings for datatype mapping for Oracle.

Queries
1. Is there any such settings for DevArt.?

2. Is there any simple way in DevArt like just use the same sql files (csdl, msl, ssdl) for devArt with some configiration. what is the best approach you suggest.

1. Is there any such settings for DevArt.?

Here is a default mapping: http://www.devart.com/dotconnect/oracle ... pping.html.

If necessary, you can change default mapping:
1) via the Tools > Options > Servers' Options > Oracle menu (applied only for Entity Developer, *.edml)
2) using the Number Mappings connection string parameter (applied only for EDM Wizard, *.edmx)

2. Is there any simple way in DevArt like just use the same sql files (csdl, msl, ssdl) for devArt with some configiration. what is the best approach you suggest.

Usage of SQL Server and Oracle simultaneously in one application can be implemented in the following alternative ways:

1. Creating repositories for 2 models

2. Using mapping which is loaded dynamically:
2.1. With 2 *.edmx (or 2 *.edml). Only one of them generates the code of model and entity classes, another one is used as a source of XML resources (example: http://www.devart.com/efquerysamples.zip)
2.2. Only one model and database independent fluent mapping: http://blog.devart.com/entity-developer ... plate.html

3. Code-First approach: http://blogs.devart.com/dotconnect/enti ... qlite.html. This article includes reference to the sample "Code-First for All Databases" which shows the way how to access different databases with the same code.
Despite the approach you will choose, we recommend you to employ Devart Entity Model (*.edml): http://www.devart.com/entitydeveloper/ed-vs-edm.html.

If this doesn't help, please specify your call stack when "Error: VMOracle.ssdl(464,6) : error 0040: The Type number is not qualified with a namespace or alias." arises.

thanks for the input.

solved using second approach. code first also is better option, we will check with that.

thanks
