What is the best way to bind decimal / double / float values with PDO in PHP?

Question

It appears the class constants only cover PDO::PARAM_BOOL, PDO::PARAM_INT and PDO::PARAM_STR for binding. Do you just bind decimal / float / double values as strings or is there a better way to treat them?

MySQLi allows the 'd' type for double, it's surprising that PDO doesn't have an equivalent when it seems better in so many other ways.

Answer 1

AFAIK PDO::PARAM_STR is the way to go.

Answer 2

You have to use PDO::PARAM_STR, but for SQLite and other engines this can have unpredictable behaviors. See this issue for one example: SQLite HAVING comparison error
