DELETE Statements
To delete information from a table, use DELETE statements.
DELETE Syntax
The DELETE statement requires the table name in the FROM clause and the row's primary key in the WHERE clause, as shown in the following example:
<delete_statement> ::= DELETE FROM <table_name> WHERE { Id = <expression> } [ { AND | OR } ... ]
<expression> ::=
| @ <parameter>
| ?
| <literal>
You can use the ExecuteNonQuery method to execute data manipulation commands and retrieve the number of affected rows, as shown in the following example:
C#
String connectionString = "APIKey=myAPIKey;";
using (LinearConnection connection = new LinearConnection(connectionString)) {
int rowsAffected;
LinearCommand cmd = new LinearCommand("DELETE FROM Issue WHERE Id = @myId", connection);
cmd.Parameters.Add(new LinearParameter("myId","fe9dfaf7-bbf7-4e34-abf8-4608880a9674"));
rowsAffected = cmd.ExecuteNonQuery();
}
VB.NET
Dim connectionString As [String] = "APIKey=myAPIKey;"
Using connection As New LinearConnection(connectionString)
Dim rowsAffected As Integer
Dim cmd As New LinearCommand("DELETE FROM Issue WHERE Id = @myId", connection)
cmd.Parameters.Add(New LinearParameter("myId", "fe9dfaf7-bbf7-4e34-abf8-4608880a9674"))
rowsAffected = cmd.ExecuteNonQuery()
End Using
