Error using Query Parameters with cfscript query

Question

Here is my code:

var qryStr = \"
            UPDATE templates_email 
            SET title = :title, test_emails = :testEmail, body = :body
            WHERE         


        

Answer 1

ColdFusion can get confused when parsing the SQL string to use parameters. The easiest way to solve this shortcoming is to put a space after each of your parameters.

Since some text editors may remove trailing whitespace, like when saving, I include an empty comment after any space at the end of a line.

var qryStr = "
    UPDATE templates_email 
    SET title = :title , test_emails = :testEmail , body = :body /**/
    WHERE id = :templateID /**/
";

Answer 2

The parser for getting the params doesn't tokenize on return values, only on whitespace (which is really annoying). Try the following:

var qryStr = "
    UPDATE templates_email 
    SET title = ( :title ), test_emails = ( :testEmail ), body = ( :body )
    WHERE ( id = :templateID )
";

The ( and ) should remove any issue with where the parser not being able to recognise where the :params stop and start.

Answer 3

This error occurs because of the tab and line break characters found in your SQL statement. I normally run below function on my SQL statement to remove these characters.

string function cleanSQL(required string sqlStatement)
    output="false"
{
return trim(reReplace(arguments.sqlStatement, "\t|\n", " ", "all"));
}

So, your setSQL() can look like:

q.setSQL(cleanSQL(qryStr))

or simply:

q.setSQL(reReplace(qryStr, "\t|\n", " ", "all"))
