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 { 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:

String connectionString = "SubscriptionKey=test;CountryVersion=2021.R2.AU;CompanyFile=Q:/CData Software.QBW;User=test;Password=test;InitiateOAuth=GETANDREFRESH;CallbackURL=http://localhost:33333;OAuthClientId=MyOAuthClientID;OAuthClientSecret=MyOAuthClientSecret;";
using (ReckonAccountsHostedConnection connection = new ReckonAccountsHostedConnection(connectionString)) {
  int rowsAffected;
  ReckonAccountsHostedCommand cmd = new ReckonAccountsHostedCommand("UPDATE Customers SET Name='Hook, Captain' WHERE Id = @myId", connection);
  cmd.Parameters.Add(new ReckonAccountsHostedParameter("myId","10456255-0015501366"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "SubscriptionKey=test;CountryVersion=2021.R2.AU;CompanyFile=Q:/CData Software.QBW;User=test;Password=test;InitiateOAuth=GETANDREFRESH;CallbackURL=http://localhost:33333;OAuthClientId=MyOAuthClientID;OAuthClientSecret=MyOAuthClientSecret;"
Using connection As New ReckonAccountsHostedConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New ReckonAccountsHostedCommand("UPDATE Customers SET Name='Hook, Captain' WHERE Id = @myId", connection)
  cmd.Parameters.Add(New ReckonAccountsHostedParameter("myId", "10456255-0015501366"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
