Bug description:PDO::prepare - First argument does not have to be a valid SQL statement
Description:
------------
statement
This must be a valid SQL statement for the target database server.
---
From manual page: http://www.php.net/pdo.prepare
---
In fact, as the text above explains, if parameters are used, the first
argument must contain a string similar to a SQL statement, but which is
not a valid SQL statement (for example, "SELECT name, colour, calories
FROM fruit WHERE calories < ? AND colour = ?"). There is a
terminological challenge here - perhaps "statement template" would
appropriately describe what the argument actually contains.
The text above is less misleading, but is also incorrect:
The SQL statement can contain zero or more named (:name) or question
mark (?) parameter markers for which real values will be substituted
when the statement is executed. You cannot use both named and question
mark parameter markers within the same SQL statement; pick one or the
other parameter style.
By the way, this does not specify what named parameter markers are, and
the manual apparently never does that. Quite clearly, these start with a
colon, but there is no specification of what constitutes a name.
Visibly, names cannot contain a dot, although the error message leaves
me wondering whether that is a bug ("PHP Fatal error: Uncaught
exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or
access violation: 0 [Sybase][ODBC Driver][SQL Anywhere]L'expression
près de ':?.nomdossier' est incorrecte", while the parameter marker I
tried using is ":dossr.nomdossier").
