UPDATE Statements
To modify existing records, use UPDATE statements.
Update Syntax
The UPDATE statement takes as input a comma-separated list of columns and new column values as name-value pairs in the SET clause, as shown in the following example:
UPDATE <table_name> SET <select_statement> | {<column_reference> = <expression> [ , ... ]} WHERE { ContactId = <expression> } [ { AND | OR } ... ]
<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 = "InitiateOAuth=GETANDREFRESH;"; using (XeroConnection connection = new XeroConnection(connectionString)) { int rowsAffected; XeroCommand cmd = new XeroCommand("UPDATE Contacts SET Name='John Doe' WHERE ContactId = @myContactId", connection); cmd.Parameters.Add(new XeroParameter("myContactId","c27221d7-8290-4204-9f3d-0cfb7c5a3d6f")); rowsAffected = cmd.ExecuteNonQuery(); }
VB.NET
Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;" Using connection As New XeroConnection(connectionString) Dim rowsAffected As Integer Dim cmd As New XeroCommand("UPDATE Contacts SET Name='John Doe' WHERE ContactId = @myContactId", connection) cmd.Parameters.Add(New XeroParameter("myContactId", "c27221d7-8290-4204-9f3d-0cfb7c5a3d6f")) rowsAffected = cmd.ExecuteNonQuery() End Using
