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 { TradingAccountUUID = <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 = "URL=http://localhost:5493/sdata/accounts50/GCRM/{C4C863BE-B098-4A7D-A78B-D7A92B8ADB59};User=Manager;Password=xxxxxx;";
using (Sage50UKConnection connection = new Sage50UKConnection(connectionString)) {
  int rowsAffected;
  Sage50UKCommand cmd = new Sage50UKCommand("UPDATE TradingAccounts SET Name='Smith' WHERE TradingAccountUUID = @myTradingAccountUUID", connection);
  cmd.Parameters.Add(new Sage50UKParameter("myTradingAccountUUID","c2ef66a5-a545-413b-9312-79a53caadbc4"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "URL=http://localhost:5493/sdata/accounts50/GCRM/{C4C863BE-B098-4A7D-A78B-D7A92B8ADB59};User=Manager;Password=xxxxxx;"
Using connection As New Sage50UKConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New Sage50UKCommand("UPDATE TradingAccounts SET Name='Smith' WHERE TradingAccountUUID = @myTradingAccountUUID", connection)
  cmd.Parameters.Add(New Sage50UKParameter("myTradingAccountUUID", "c2ef66a5-a545-413b-9312-79a53caadbc4"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
