Insert
This method is used to insert a data entity object as a new row in the table.
Code Snippets
Below is the sample code to insert a row into the [dbo].[Person]
table.
using (var connection = new SqlConnection(connectionString))
{
var id = connection.Insert<Person, int>(new Person
{
Name = "John Doe",
Address = "New York",
DateOfBirth = DateTime.Parse("2020-01-01"),
IsActive = true,
DateInsertedUtc = DateTime.UtcNow
});
}
The result will vary from the value of the
GlobalConfiguration.Options
property KeyColumnReturnBehavior.
Targeting a Table
You can also target a specific table by passing the literal table like below.
using (var connection = new SqlConnection(connectionString))
{
var person = new Person
{
Name = "John Doe",
Address = "New York",
DateOfBirth = DateTime.Parse("2020-01-01"),
IsActive = true,
DateInsertedUtc = DateTime.UtcNow
};
var id = connection.Insert<Person>("[dbo].[Person]",
entity: person);
}
Or via Anonymous Type.
using (var connection = new SqlConnection(connectionString))
{
var person = new
{
Name = "John Doe",
Address = "New York",
DateOfBirth = DateTime.Parse("2020-01-01"),
IsActive = true,
DateInsertedUtc = DateTime.UtcNow
};
var id = connection.Insert("[dbo].[Person]",
entity: person);
}
Or via Dictionary<string, object>
or ExpandoObject.
using (var connection = new SqlConnection(connectionString))
{
var person = new Dictionary<string, object>
{
{ "Name", "John Doe" },
{ "Address", "New York" },
{ "DateOfBirth", DateTime.Parse("2020-01-01") },
{ "IsActive", true },
{ "CreatedDateUtc", DateTime.UtcNow }
};
var id = connection.Insert<int>("[dbo].[Customer]",
entity: person);
}
The library will add the newly created value of the identity column into the
Dictionary<string, object>
or ExpandoObject object (if not present).
Specific Columns
You can also target a specific columns to be inserted by passing the list of fields to be included in the fields
argument.
using (var connection = new SqlConnection(connectionString))
{
var person = new Person
{
Name = "John Doe",
Address = "New York",
DateOfBirth = DateTime.Parse("2020-01-01"),
IsActive = true,
DateInsertedUtc = DateTime.UtcNow
};
var fields = Field.Parse<Person>(e => new
{
e.Name,
e.DateOfBirth,
e.DateInsertedUtc
})
var id = connection.Insert<Person>(entity: person,
fields: fields);
}
Or via dynamics.
using (var connection = new SqlConnection(connectionString))
{
var person = new
{
Name = "John Doe",
DateOfBirth = DateTime.Parse("2020-01-01"),
DateInsertedUtc = DateTime.UtcNow
};
var id = connection.Insert("[dbo].[Person]",
entity: person));
}
And with the target fields.
using (var connection = new SqlConnection(connectionString))
{
var person = new
{
Name = "John Doe",
Address = "New York",
DateOfBirth = DateTime.Parse("2020-01-01"),
IsActive = true,
DateInsertedUtc = DateTime.UtcNow
};
var id = connection.Insert("[dbo].[Person]",
entity: person,
fields: Field.From("Name", "DateOfBirth", "DateInsertedUtc"));
}
Table Hints
To pass a hint, simply write the table-hints and pass it in the hints
argument.
using (var connection = new SqlConnection(connectionString))
{
var id = connection.Insert<Person>(person,
hints: "WITH (TABLOCK)");
}
Or, you can use the SqlServerTableHints class.
using (var connection = new SqlConnection(connectionString))
{
var id = connection.Insert<Person>(person,
hints: SqlServerTableHints.TabLock);
}
