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 { AccountId = <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;OrganizationUrl=https://myaccount.operations.dynamics.com/;";
using (D365FinOpConnection connection = new D365FinOpConnection(connectionString)) {
  int rowsAffected;
  D365FinOpCommand cmd = new D365FinOpCommand("UPDATE Accounts SET Name='John' WHERE AccountId = @myAccountId", connection);
  cmd.Parameters.Add(new D365FinOpParameter("myAccountId","'00000000-0000-0000-0000-000000000000'"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://myaccount.operations.dynamics.com/;"
Using connection As New D365FinOpConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New D365FinOpCommand("UPDATE Accounts SET Name='John' WHERE AccountId = @myAccountId", connection)
  cmd.Parameters.Add(New D365FinOpParameter("myAccountId", "'00000000-0000-0000-0000-000000000000'"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
