Description
Program fails at Microsoft.Data.SqlClient.SqlException: 'Must declare the scalar variable "@InvoiceTemplateId".
Statement(s) could not be prepared.' The exception throws if Select statement contains field with another database column name as defined by model.
Program not throws the exception without Select statement which specified concrete columns.
Steps To Reproduce
string[] columns = new[] { nameof(InvoiceTemplateSettings.DocumentId), nameof(InvoiceTemplateSettings.TemplateName) };
IDbSet<InvoiceTemplateSettings> dbSet = _database.Query<InvoiceTemplateSettings>().Select(columns).AsDbSet();
var documentFlat = new InvoiceTemplateSettings() {
DocumentId = 7,
TemplateName = "zmenená šablónka"
};
dbSet.Edit(documentFlat);
await dbSet.CommitChangesAsync();
And the console show
UPDATE [InvoiceTemplateSettings]
SET [TemplateName] = @TemplateName
WHERE ([InvoiceTemplateId] = @InvoiceTemplateId)
WITH PARAMETERS (zmenená šablónka)
Model is
public class InvoiceTemplateSettings
{
/// <summary>
/// Invoice template ID.
/// </summary>
public long DocumentId { get; set; }
public string TemplateName { get; set; }
}
Model builder is
modelBuilder.Entity<Entities.InvoiceTemplateSettings>()
.HasTableName(DatabaseTableNames.InvoiceTemplateSettingsTableName)
.HasPrimaryKey(f => f.DocumentId)
.Property(f => f.DocumentId).HasColumnName("InvoiceTemplateId");
SQL
CREATE TABLE [dbo].[InvoiceTemplateSettings] (
[InvoiceTemplateId] [bigint] NOT NULL,
[TemplateName] [nvarchar](250) NOT NULL,
CONSTRAINT [UK_InvoiceTemplateSettings] UNIQUE NONCLUSTERED (
[InvoiceTemplateId] ASC
)
WITH (
PAD_INDEX = OFF,
STATISTICS_NORECOMPUTE = OFF,
IGNORE_DUP_KEY = OFF,
ALLOW_ROW_LOCKS = ON,
ALLOW_PAGE_LOCKS = ON,
OPTIMIZE_FOR_SEQUENTIAL_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]
)
If I replace the line with the query without .Select(columns)
statement:
IDbSet<InvoiceTemplateSettings> dbSet = _database.Query<InvoiceTemplateSettings>().AsDbSet();
the code runs success without exception.
Expected behavior
I think this is a bug because I must use the name of database column, not column of model. I would expect to use model column name.
