Usage

• Update entities, without result for best performance:

await connection.BulkUpdateAsync(data);

• Inserts entities, without result for best performance:

connection.BulkInsert(data);

await connection.BulkInsertAsync(data);

• Inserts and returns inserted entities:

var inserted = connection.BulkInsertAndSelect(data);

var inserted = await connection.BulkInsertAndSelectAsync(data);

Default Conventions

• TableName is TypeName + s. When Interface I is removed.
• Key is Id property (case-insensitive)

Custom Conventions

TableName - somewhere before usage call.

TableMapper.SetupConvention("tbl", "s")

Attributes

We do not rely on specific attributes. This means you can use whatever attributes with following names:

• TableAttribute - Must have string Name property. Exists in System.ComponentModel.Annotations Nuget.
• ColumnAttribute - Must have string Name property. Exists in System.ComponentModel.Annotations Nuget.
• KeyAttribute - Marking only attribute. Exists in System.ComponentModel.Annotations Nuget.
• ComputedAttribute - Marking only attribute. For fields returned from Db.
• NotMapped - Marking only attribute. For ignored fields.

// Table Cars by default convention 
public class Car
{
    // Identity by convention
    public int Id { get; set; }
    
    public string Name { get; set; }

}

// Supported in v1.2+
public enum CarType : int
{
    Classic = 1,

    public int CarId { get; set; }
    
    public string Name { get; set; }
	
    public CarType CarType { get; set; } //SQL Data Type should match Enum type
