SQLite3Stmt::clear — Clears all current bound parameters
Clears all current bound parameters (sets them to null).
This method needs to be used with SQLite3Stmt::reset().
If used alone, any call to
SQLite3Stmt::bindValue() or
SQLite3Stmt::bindParam() will be of no effect
and all bound parameters will have the null value.
此函數沒(méi)有參數。
Returns true on successful clearing of bound parameters, false on
failure.
