Error While Using Pdo Prepared Statements and Limit in Query

Error while using PDO prepared statements and LIMIT in query

Regarding to post LIMIT keyword on MySQL with prepared statement , the code below could solve my problem.

$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, FALSE);

Thanks Álvaro G. Vicario and Maerlyn

PDO Prepared Statement with % and Limit

bindParam requires a variable reference so it won't work with as

bindParam(":min", 0, PDO::PARAM_INT)

You could create one like $zero = 0, but this seems unnecessary so you can just use bindValue instead. Same for (int)$limiter which becomes a value rather than a variable.

My PDO Prepared Statement is not working with a fetchALL and Limit

replace the below line

$stmt->execute([$somequantity]);

with

$stmt->bindParam(1, $somequantity, PDO::PARAM_INT);
$stmt->execute();

PHP PDO Prepared Statement parameter causing error

Your $limit parameter is being escaped as one parameter, where it should be escaped as two. Your sql will currently look something like "limit '0, 8';" where it should look like "limit 0, 8";

To solve this, you should split your limit parameter into two. Edit the end of your SQL to look like:

LIMIT :offset, :limit

And your parameter list to look like:

$query_params = array (
    ':offset' => ($pagenum - 1) * $page_rows,
    ':limit' => $page_rows
);

As Mr Smith mentioned, you'll also have to add the line:

$db->setAttribute( PDO::ATTR_EMULATE_PREPARES, false );

To ensure the limit parameters are correctly handled as integers rather than strings.

PDO Prepare Statement Limit Not Working

Solved.

$sth->bindParam(':limit', $limit, PDO::PARAM_INT);

How to get total amount of rows while using limit when using PDO prepared statements?

You can use the SQL_CALC_FOUND_ROWS command to tell MySQL to return the total of the matching records

$sql = "SELECT SQL_CALC_FOUND_ROWS * FROM `tab`
WHERE `condition` = :condition 
LIMIT $page_size OFFSET $offset";

To get the total rows found you can run this query

SELECT FOUND_ROWS()

However, it is often faster to execute 2 separate queries than using SQL_CALC_FOUND_ROWS. Here is a benchmark to explain
