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 = "Url = https://try.acumatica.com/ISV/entity/Default/17.200.001/;User=user;Password=password;Company=CompanyName;";
using (AcumaticaConnection connection = new AcumaticaConnection(connectionString)) {
  int rowsAffected;
  AcumaticaCommand cmd = new AcumaticaCommand("UPDATE Events SET location_displayName='Zenburger' WHERE Id = @myId", connection);
  cmd.Parameters.Add(new AcumaticaParameter("myId","Jq74mCczmFXk1tC10GB"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "Url = https://try.acumatica.com/ISV/entity/Default/17.200.001/;User=user;Password=password;Company=CompanyName;"
Using connection As New AcumaticaConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New AcumaticaCommand("UPDATE Events SET location_displayName='Zenburger' WHERE Id = @myId", connection)
  cmd.Parameters.Add(New AcumaticaParameter("myId", "Jq74mCczmFXk1tC10GB"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
