![]() Please note, that PDO format numbers according to current locale. Once that is done for each returning rowset you will have access to the output parameters. Otherwise you need to process the rows, and then: If your stored procedure does not return any rowsets (no SELECT statements) then you are set, your output parameters will be ready as soon as the stored procedure is processed. When using bound output parameters with a stored procedure, the output parameters are updated AFTER the LAST rowset has been processed. If this was in the documentation, I didn't stumble across it. note: this will fail since $active is now "1" bindParam ( ":active", $active, PDO :: PARAM_INT ) This can cause problems when trying to compare values using the = operator. Note that when using PDOStatement::bindParam an integer is changed to a string value upon PDOStatement::execute(). This will fail ($val by value, because bindParam needs &$variable): $sth -> bindParam ( ':keyword', $keyword, PDO :: PARAM_STR ) Put the percentage sing on the keyword prepare ( 'SELECT * FROM `users` WHERE `firstname` LIKE :keyword' ) "SELECT * FROM `users` WHERE `firstname` LIKE :keyword" Īnd then add the percentages to the php variable where you store the keyword:Īnd finally the quotes will be automatically added by PDO when executing the query so you don't have to worry about them. ![]() The CORRECT solution is to leave clean the placeholder like this: ![]() "SELECT * FROM `users` WHERE `firstname` LIKE '%:keyword%'" If you use PDO bindParam to do a search with a LIKE condition you cannot put the percentages and quotes to the param placeholder '%:keyword%'. I know this has been said before but I'll write a note on it too because I think it's important to keep in mind: PDOStatement::bindValue() - Binds a value to a parameter.PDOStatement::execute() - Executes a prepared statement.PDO::prepare() - Prepares a statement for execution and returns a statement object.Print( "After pureeing fruit, the colour is: $colour " ) $sth -> bindParam ( 1, $colour, PDO :: PARAM_STR | PDO :: PARAM_INPUT_OUTPUT, 12 ) $sth -> bindParam ( 2, $colour, PDO :: PARAM_STR, 12 ) Įxample #3 Call a stored procedure with an INOUT parameter WHERE calories bindParam ( 1, $calories, PDO :: PARAM_INT ) $sth -> bindParam ( ':colour', $colour, PDO :: PARAM_STR, 12 ) Įxample #2 Execute a prepared statement with question mark placeholders WHERE calories bindParam ( ':calories', $calories, PDO :: PARAM_INT ) prepare ( 'SELECT name, colour, calories Returns TRUE on success or FALSE on failure.Įxample #1 Execute a prepared statement with named To indicate that a parameter is an OUT parameter from a stored procedure, you must explicitly set the length. To return an INOUT parameter from a stored procedure, use the bitwise OR operator to set the PDO::PARAM_INPUT_OUTPUT bits for the data_type parameter. data_typeĮxplicit data type for the parameter using the PDO::PARAM_* constants. Variable to bind to the SQL statement parameter. For a prepared statement using question mark placeholders, this will be the 1-indexed position of the parameter. For a prepared statement using named placeholders, this will be a parameter name of the form :name. ![]() Input/output parameters that both send in data and are updated to receive it. Some drivers support the invocation of stored procedures that return data as output parameters, and some also as ![]() Most parameters are input parameters, that is, parameters that are used in a read-only fashion to build up the query.
