如何在c＃中組合一個sql查詢

Question

sql = "SELECT * " +                   
      "FROM memberTable " +
      "WHERE Hometown = 'St.Pete, FL' AND " +
      "DELETE Relationship FROM memberTable WHERE Relationship ='self'"+
      "ORDER BY LastName ASC, FirstName ASC, Relationship, Hometown;";

這是我的代碼，我正在編寫一個程序，它將刪除關系“self”並顯示Hometown = "St.Pete, FL" 。 我無法弄清楚如何添加到WHERE子句。

Answer 1

sql =
                "SELECT * " +
                "FROM memberTable " +
                "WHERE Hometown = 'St.Pete, FL' AND Relationship <> 'self'" +
                "ORDER BY LastName ASC, FirstName ASC;";

這就是我終於得到它的工作！

Answer 2

做這樣的事情

var deleteQuery = @" DELETE Relationship FROM memberTable WHERE Relationship ='self'";
var selectQuery = @"SELECT * FROM memberTable WHERE Hometown = 'St.Pete, FL' ORDER BY LastName ASC, FirstName ASC, Relationship, Hometown";
var combinedQuery = string.Format("{0};{1}", deleteQuery, selectQuery);
