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 { <column_reference> = <expression> } [ , ... ] WHERE { Id = <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 = "OAuthClientID=myClientID;OAuthClientSecret=myClientSecret"; using (XeroWorkflowMaxConnection connection = new XeroWorkflowMaxConnection(connectionString)) { int rowsAffected; XeroWorkflowMaxCommand cmd = new XeroWorkflowMaxCommand("UPDATE Clients SET Name='John' WHERE Id = @myId", connection); cmd.Parameters.Add(new XeroWorkflowMaxParameter("myId","9d382fcf-7013-4d97-8dd8-c08e8b26a0b2")); rowsAffected = cmd.ExecuteNonQuery(); }
VB.NET
Dim connectionString As [String] = "OAuthClientID=myClientID;OAuthClientSecret=myClientSecret" Using connection As New XeroWorkflowMaxConnection(connectionString) Dim rowsAffected As Integer Dim cmd As New XeroWorkflowMaxCommand("UPDATE Clients SET Name='John' WHERE Id = @myId", connection) cmd.Parameters.Add(New XeroWorkflowMaxParameter("myId", "9d382fcf-7013-4d97-8dd8-c08e8b26a0b2")) rowsAffected = cmd.ExecuteNonQuery() End Using
