Does the code that you posted include the 218th line of your script "LMCE_Connector.pm" file? My guess is "no". That particular kind of sql error string results from trying to "prepare()" an sql statement that includes a perl variable (e.g. "select * from $table_name"), and the value of the variable is wrong for that slot in the sql statement.

From the content of the error report, it looks like you are passing a scalar that holds some sort of reference (hash or array ref), the sql statement is supposed to have some sort of string in that position, and perl is "stringifying" the value of the reference (a memory address).

Since the code you've shown involves string constants with no variables in the two "prepare()" calls, your sql error was not caused by either of those calls. The problem is somewhere else (hint: look at what is being passed to the prepare() call at line 218 in your code).
