My contribution to the insanity.. INSERT statements made easy:
$genericQY = "INSERT INTO MOD_LMGR_Leads ("; $genericQYvalues = " VALUES (";
$genericQY .= " FirstName,"; $genericQYvalues .= " 'John',";
$genericQY .= " LastName"; $genericQYvalues .= " 'Smith'";
$genericQY .= " )"; $genericQYvalues .= " );";
$genericQY .= $genericQYvalues;
$genericRS = mysql_query($genericQY);
I use this structure so if I decide that I don't need certain data I can comment out a single line to remove the column name and corresponding value. Also helpful for making updates to column/value pairs and not worry about the dreaded error involve # of columns not matching.
Only things you have to watch for:
1. Make sure you don't have a comma on the last item
2. Make sure you have spaces where appropriate so when it concatenates the strings, you don't get stuff crammed together (not really an issue with the INSERT statement, but I try to keep a consistant practice with all my queries so I don't slip up.. SELECT columnsFROM tableWHERE something = something is where it really gets ya if you forget spaces.. just as an example)
3. Make sure to remember to concatenate the "query" and "values" parts
I like to think this is a little "outside the box" thinking since common practice is "one command, one line" or "total chaos" hah.
Any comments on improving this or other unique stylistic ways people like to design their code?

I meant ONLY the SELECT part on a single line.
Only a moron would cram the FROM and all that into the same line.
:-)
$query = "SELECT blah1, blah2, blah3, ... blah147 ";
$query .= " FROM table1 ";
$query .= " LEFT OUTER JOIN table2 ";
$query .= " ON blah7 = blah42 ";
$query .= " WHERE blah16 ";
$query .= " AND blah42 ";
$query .= " ORDER BY blah9, blah8 desc, blah6 ";
is what I go for.
The SELECT line is the only one that ever gets all that long, really...
