parameterized-query

I'm new to parametrized SQL. I've got a query in an .asp page that's getting one or more client names from a form. These are held in an array called clientArr and then passed through to SQL server as parameters. I'm escaping the ' as '' but this doesn't appear to be working. If I run the query with a client name like McDonald's , it returns no results. clientArr(y) = Replace(clientArr(y),"'","''" ... if qsClient > "" Then dim booComma booComma = false if mySQLwhere > "" Then mySQLwhere = mySQLwhere& " AND " End if mySQLwhere = mySQLwhere & " (p.client IN ( " for y = 0 to Ubound(clientArr) if

I am currently learning parametrized queries as there are advantages to using them. Could someone give some pointers by converting this block of code to a parametrized version? Thanks. if(isset($_GET['news_art_id']) && (!empty($_GET['news_art_id']))) { $news_art_id = htmlentities(strip_tags($_GET['news_art_id'])); $news_art_id = validate_intval($news_art_id); //echo $news_art_id; $_SESSION['news_art_id'] = $news_art_id; // Assign value to status. $onstatus = 1; settype($onstatus, 'integer'); $query = 'SELECT M.id, M.j_surname, M.j_points_count, M.j_level, A.j_user_id,A.id, A.jart_title, A.jart

Objective: Using C# and SQL2008 correctly setup a Parameterized SQL Insert statement Issue: The following statement is used in a for loop so the values must be cleared. Upon running this code it states there is a syntax error near 250. The code is as follows for (int i = 0; i < Rows.Count; i++) { cmd.Parameters.Clear(); struct Row = (struct)Rows[i]; sql = "@RowName varchar(250) = null " + "INSERT INTO " + "database.dbo.table" + "(database.dbo.tabe.RowName) " + "VALUES " + "(@RowName) "; cmd.CommandText = sql; cmd.Parameters.AddWithValue("@RowValue ", Row.RowName); } Thank you in advance for

I am trying to use a simple MySQL insert query with the parameters in array form. It keeps telling me the number of parameters are wrong. I have tried the following, all producing the same error: $stmt3 = $link->prepare('INSERT INTO messages VALUES(null, :room, :name, :message, :time, :color)'); $stmt3->execute(array(':room' => $Clean['room'],':name' => $Clean['name'],':message' => $Clean['message'],':time' => $time,':color:' => $Clean['color'])); and $stmt3 = $link->prepare('INSERT INTO messages VALUES(:null, :room, :name, :message, :time, :color)'); $stmt3->execute(array(':null' => null, '

I am attempting to run a parameterized query against a DB2 database from .NET using the Client Access ODBC Driver using the following code: var db2Cmd = new OdbcCommand("INSERT INTO presnlats (LAT) VALUES (@LAT)", db2Conn); db2Cmd.Parameters.AddWithValue("@LAT", insertValue); Console.Out.WriteLine(db2Cmd.ExecuteNonQuery()); When executed, an OdbcException is thrown: ERROR [42S22] [IBM][iSeries Access ODBC Driver][DB2 UDB]SQL0206 - Column @LAT not in specified tables. The internets seem to imply that parameterized queries are supported by the client access ODBC driver, but this error seems to

I've been trying to figure out why the following code is not generating any data in my ResultSet: String sql = "SELECT STUDENT FROM SCHOOL WHERE SCHOOL = ? "; PreparedStatement prepStmt = conn.prepareStatement(sql); prepStmt.setString(1, "Waterloo"); ResultSet rs = prepStmt.executeQuery(); On the other hand, the following runs properly: String sql = "SELECT STUDENT FROM SCHOOL WHERE SCHOOL = 'Waterloo' "; PreparedStatement prepStmt = conn.prepareStatement(sql); ResultSet rs = prepStmt.executeQuery(); The data type for SCHOOL is CHAR (9 Byte). Instead of setString, I also tried: String sql =
