If you wish to store a string which actually begins and ends with

single quotes, you must add a space or other non-single-quote character
|

to the beginning or end of the parameter, which will prevent the
|
||
parameter from being taken as a file name. If this is not an option,
|

then you must use another mechanism to store the string, such as

executing the query directly with <span class="function"><a href="odbc_exec.html" class="function">odbc_exec()</a></span>).
