PDO Parameterized Queries: Reusing Named Placeholders
When dealing with PDO parameterized queries, one may encounter a need to utilize the same value for multiple named placeholders in a single statement. For instance:
SELECT :Param FROM Table WHERE Column = :Param
Intuitively, one might attempt to bind the value to a named placeholder and expect it to be used for all occurrences. However, this approach is not possible in PDO.
The PDO::prepare documentation explicitly states:
"...you cannot use a named parameter marker of the same name twice in a prepared statement"
Therefore, it is not feasible to reuse named placeholders in this manner.
