INSERT Statements
To create new records, use INSERT statements.
INSERT Syntax
The INSERT statement specifies the columns to be inserted and the new column values. You can specify the column values in a comma-separated list in the VALUES clause, as shown in the following example:
INSERT INTO <table_name>
( <column_reference> [ , ... ] )
VALUES
( { <expression> | NULL } [ , ... ] )
<expression> ::=
| @ <parameter>
| ?
| <literal>
You can use the ExecuteNonQuery method to execute data manipulation commands and retrieve the rows affected, as shown in the following example:
C#
String connectionString = "AWS Access Key=xxx;AWS Secret Key=xxx;Domain=amazonaws.com;AWS Region=OREGON;"; using (AmazonDynamoDBConnection connection = new AmazonDynamoDBConnection(connectionString)) { int rowsAffected; AmazonDynamoDBCommand cmd = new AmazonDynamoDBCommand("INSERT INTO Account (Name) VALUES ('John')", connection); rowsAffected = cmd.ExecuteNonQuery(); }
VB.NET
Dim connectionString As [String] = "AWS Access Key=xxx;AWS Secret Key=xxx;Domain=amazonaws.com;AWS Region=OREGON;" Using connection As New AmazonDynamoDBConnection(connectionString) Dim rowsAffected As Integer Dim cmd As New AmazonDynamoDBCommand("INSERT INTO Account (Name) VALUES ('John')", connection) rowsAffected = cmd.ExecuteNonQuery() End Using
Retrieving Generated Ids
In order to retrieve the Id of the last inserted record, use the SCOPE_IDENTITY function, as shown in the following example:C#
cmd = connection.CreateCommand(); cmd.CommandText = "SELECT SCOPE_IDENTITY()"; Object returnedValues = cmd.ExecuteScalar(); String Id = (String)returnedValues;
VB.NET
cmd = connection.CreateCommand() cmd.CommandText = "SELECT SCOPE_IDENTITY()" Dim returnedValues As [Object] = cmd.ExecuteScalar() Dim Id As [String] = returnedValues
