I have written a seemingly simple UDF for cleaning up data before an insert
or update statement (it trims the string, inserts null when necessary, wraps
string in single quotes if it's a char field):
<cfscript>
function checknull(ii,isint) {
if (isint) {
return iif(len(trim(ii)),de(trim(ii)),de("null")); }
else {
return
iif(len(trim(ii)),de(chr(39)&trim(ii)&chr(39)),de("null")); }
}
</cfscript>
Basically, my insert statement looks like:
Insert into tablename (intfield,charfield)
Values (#checknull(intfield,1)#,#checknull(charfield,0)#)
It works great except for when the charfield contains apostrophes. It
escapes them all and the result is that twice as many apostrophes get
inserted. I know that somewhere in here I should probably be using
preservesinglequotes() but everywhere I attempt to use it in the UDF I get a
JIT compilation error. I also get a JIT if I put the preservesinglequotes
function in the calling template
[preservesinglequotes(checknull(charfield,0))]
Any suggestions? Please? Unfortunately I used this function all through an
app before finding the bug, so I would be psyched to make repairs to the
function itself not all the code that uses it.
