ColumnAttribute Name does not work about dbextensions HOT 8 CLOSED

How are you building the query? If you are using SqlBuilder or a plain string, you are responsible for the column to property mapping.

from dbextensions.

var query = SQL.SELECT("TOP (1) *").FROM("MyTableName"); var execution = _db.Map<MyTableName>(query)?.First();

Isn't this the correct way?

from dbextensions.

Try this:

var execution = _db.Table<MyTableName>()
    .First();

from dbextensions.

Try this:

var execution = _db.Table<MyTableName>()
    .First();

Gives the same result back as my previous code.
Seems like Column name property is not working correctly? Which is bad for me because there are some columns that start with numbers on my database and C# does not accept numbers as property names.

[Column(Name = "ColumnName")]

Are you using the Table attribute on the entity class?

from dbextensions.

Are you using the Table attribute on the entity class?

 [Table(Name = "MyTableName")]
 public class MyTableName
 {
 [Column(Name = "nOffer")]
public int Offer { get; set; }
 }

Yeah like this.

This code :

 var query = SQL.SELECT("TOP (1) *").FROM("MyTableName"); 
 var execution = _db.Map<MyTableName>(query)?.First();

and this one:

var execution = _db.Table<MyTableName>().First();

Returns a row but the Offer parameter is value 0. In the database nOffer value is 257.

from dbextensions.

I cannot reproduce the issue. If you call _db.Table<MyTableName>().GetDefiningQuery().ToString() what do you get? That way we can find out if it's using the column name or not.

from dbextensions.

Aha my bad it all makes sense right now.

DbExtensions uses the given Column name value to build SQL like:

SELECT [nOffer] AS [Offer]
FROM [MyTableName]

So if i build a query using DbExtensions SQL object i should type it as follow:

SQL.Select("TOP 1 [nOffer] AS [Offer]"); 

Which returns the correct database value.

Thank you very much for the support.
