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 { EmployeeId = <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;OAuthClientID=YourClientId;OAuthClientSecret=YourClientSecret;CompanyId=YourCompanyId;";
using (PaylocityConnection connection = new PaylocityConnection(connectionString)) {
  int rowsAffected;
  PaylocityCommand cmd = new PaylocityCommand("UPDATE Employee SET LastName='John' WHERE EmployeeId = @myEmployeeId", connection);
  cmd.Parameters.Add(new PaylocityParameter("myEmployeeId","1234"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "InitiateOauth=GETANDREFRESH;OAuthClientID=YourClientId;OAuthClientSecret=YourClientSecret;CompanyId=YourCompanyId;"
Using connection As New PaylocityConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New PaylocityCommand("UPDATE Employee SET LastName='John' WHERE EmployeeId = @myEmployeeId", connection)
  cmd.Parameters.Add(New PaylocityParameter("myEmployeeId", "1234"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
