prepared-statement

i am using mysqli prepared statement to insert record in the table like this $link = mysqli_connect('localhost', 'my_user', 'my_password', 'world'); /* check connection */ if (!$link) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $stmt = mysqli_prepare($link, "INSERT INTO CountryLanguage VALUES (?, ?, ?, ?)"); mysqli_stmt_bind_param($stmt, 'sssd', $code, $language, $official, $percent); $code = 'DEU'; $language = 'Bavarian'; $official = "F"; $percent = 11.2; /* execute prepared statement */ mysqli_stmt_execute($stmt); if(mysqli_stmt_affected_rows($stmt) > 0){ //if insert

From Java, I'm calling a prepared statement in Postgresql with an insert that has a RETURNING clause for my identity column. In PG admin it comes right back, but not sure how to get it from my prepared statement: String insertStatement = "INSERT INTO person(\n" + " name, address, phone, customer_type, \n" + " start_dtm)\n" + " VALUES (?, ?, ?, ?, \n" + " ?)\n" + " RETURNING person_id;"; PreparedStatement stmt = connection.prepareStatement(insertStatement); stmt.setObject(1, perToSave.getName(null)); stmt.setObject(2, editToSave.getAddress()); stmt.setObject(3, editToSave.getPhone()); stmt

I have a table in the database: create table store ( ... n_status integer not null, t_tag varchar(4) t_name varchar, t_description varchar, dt_modified timestamp not null, ... ); In my stored function I need to execute the same select against this table multiple times: select * from store where n_place_id = [different values] and t_tag is not null and n_status > 0 and (t_name ~* t_search or t_description ~* t_search) order by dt_modified desc limit n_max; Here, t_search and n_max are parameters into the stored function. I thought it would make sense to use a prepared statement for this, but I

Problem How to call two MySQL stored procedures in the same mysqli connection using prepared statements (or another query method equally safe against SQL injections) without getting the following errors: Warning: Packets out of order. Expected 1 received 61. Packet size=7 in /... Warning: mysqli::prepare(): MySQL server has gone away in /... Got the code hooked up online at tutorialspoint Story I'm making a PHP backend with a MySQL database. I have two results that I want to get from one query: a list of weekly summaries, and a summary of all the weeks. ┌───────┬────────────┬────────────┬─────

Here's my current SQL statement: SEARCH_ALBUMS_SQL = "SELECT * FROM albums WHERE title LIKE ? OR artist LIKE ?;"; It's returning exact matches to the album or artist names, but not anything else. I can't use a '%' in the statement or I get errors. How do I add wildcards to a prepared statement? (I'm using Java5 and MySQL) Thanks! Paul Tomblin You put the % in the bound variable. So you do stmt.setString(1, "%" + likeSanitize(title) + "%"); stmt.setString(2, "%" + likeSanitize(artist) + "%"); You should add ESCAPE '!' to allow you to escape special characters that matter to LIKE in you inputs.

$Query = pg_query_params($db, 'SELECT username FROM users WHERE id = $1 AND password=(crypt(\'$2\',password)) LIMIT 1', array(33,'thepassword')); "bind message supplies 2 parameters, but prepared statement "" requires 1" The problem seem around the '$2' parameter, heredoc string doesnt works. Suggestions ? Single quotes are used in SQL for string literals. That means that this: '$2' is just a string that contains the characters $ and 2 rather than a placeholder. If you want a placeholder, you need to leave out the quotes: $Query = pg_query_params($db, '...password=(crypt($2,password))...',

I'm new to mysql and php and wanted to clarify something on prepared-statements. All the examples I've seen only add params for the actual data in the table, is it bad practice to paramaterise all the fields so there are less statements? e.g. UPDATE ? SET ?=? WHERE ID=? Thank you You cannot parameterize identifiers. You can only parameterize data . Otherwise the main point of parameterization, the separation between statement structure and data , is pretty moot. Understand that parameterization is not just fancy copy-and-paste, it's a technique to make sure the database has a clear separation
