prepared-statement

Im currently scratching my head at how to implement SQL_CALC_FOUND_ROWS with prepared statements. I'm writing a pagination class and obviously i want to add LIMIT to the query but also find what the total number of rows would be. Heres an example from the class in question. $query="select SQL_CALC_FOUND_ROWS id,title,location,salary,employer from jobs where region=38 limit 0,3"; if($stmt = $connection->prepare($query)) { $stmt->execute()or die($connection->error); //execute query $stmt->bind_result($id,$title,$location,$salary,$employer,$image); while($stmt->fetch()){ $jobs[$x]['id']=$id;

We all know that we should rather reuse a JDBC PreparedStatement than creating a new instance within a loop. But how to deal with PreparedStatement reuse between different method invocations? Does the reuse-"rule" still count? Should I really consider using a field for the PreparedStatement or should I close and re-create the prepared statement in every invocation (keep it local)? (Of course an instance of such a class would be bound to a Connection which might be a disadvantage in some architectures) I am aware that the ideal answer might be "it depends". But I am looking for a best practice

As per my understanding the use of PreparedStatement in Java is we can use it multiple times. But I have some confusion using PreparedStatementCreator of Spring JDBC. For example consider following code, public class SpringTest { JdbcTemplate jdbcTemplate; PreparedStatementCreator preparedStatementCreator; ResultSetExtractor<String> resultSetExtractor; public SpringTest() throws SQLException { jdbcTemplate = new JdbcTemplate(OracleUtil.getDataSource()); preparedStatementCreator = new PreparedStatementCreator() { String query = "select NAME from TABLE1 where ID=?"; public PreparedStatement

Is there a way to do transactions with prepared statements? I mean can I use the following example with $mysqli->autocommit(FALSE); and $mysqli->commit( ); and $mysqli->rollback( ); //Preparing the statment $insert_stmt=$mysqli->prepare("INSERT INTO x VALUES(?,?)") or die($mysqli->error); //associate variables with the input parameters $insert_stmt->bind_param("is", $my_number,$my_string); //i=integer //Execute the statement multiple times.... for ($my_number = 1; $my_number <= 10; $my_number++) { $my_string="row ".$my_number; $insert_stmt->execute() or die ($insert_stmt->error); } $insert

Just last week, I was doing some PHP stuff. I worked a little solution to prevent SQL injections. PHP has been always my man, it has readily 3 solutions for use (maybe more). One is to enable "magic queries" using stripslashes() function. Another one (the recommended) is to use mysql_real_escape_string() function. That simple and my problem is solved. However, things don't seem to be that simple when it comes to JSP. I searched and didn't find any built-in function to strip slashes or do those sort of things (I believe such functionality can be implemented using basic JAVA functions but...).

Let's say I want to select records where Id = 30 . Prepared statements allow two ways of binding parameters: question marks $id = 30; $q = $conn->prepare("SELECT * FROM pdo_db WHERE id > ?"); $q->execute(array($id)); // Here above ID will be passed named parameters $sth = $conn->prepare("SELECT `id`, `title` FROM `pdo_db` WHERE `id` > :id"); $sth->execute(array( ':id' => 30 )); Both are working fine and give accurate results but I am not able to get the exact differences between these two nor when I should use one or another? Question mark parameters are called positional parameters.

Im building a large database call using PreparedStatement that has 2000+ parameter markers. Im getting this error Caused by: java.sql.SQLException: Prepared or callable statement has more than 2000 parameter markers. at net.sourceforge.jtds.jdbc.SQLParser.parse(SQLParser.java:1139) at net.sourceforge.jtds.jdbc.SQLParser.parse(SQLParser.java:156) at net.sourceforge.jtds.jdbc.JtdsPreparedStatement.<init>(JtdsPreparedStatement.java:107) Caused by: java.sql.SQLException: Prepared or callable statement has more than 2000 parameter markers. I tried searching the API Docs and google but couldnt find
