in thread Test if string is already quote()'d?
I use placeholders when possible, but I'm encountering difficulty in situations where I am building an SQL statement depending on various conditions.
The only way I have found to handle such a situation is to build the SQL statement into a scalar such as $sql and then do a prepare($sql) or do($sql). But then I have to figure out how to build the execute() so I can stick the bind values in. Since the statement I'm building will have a different number and placement of placeholders depending on the situation, the number and order of values to stick in execute() will vary, too.
I have tried a number of joins and mappings to make this all come out right, but it's nearly impossible to stuff all the values into the right order when the statement can vary drastically from one run to another.
Also, as I understood from the DBI docs, do() should prepare (including escape quoting) a statement -- but this only seems to be true if you're using placeholders. In other words, if I build a statement and stuff it into $sql (where $sql contains the full statement without any placeholders) and run do($sql), my strings are still naked.
