I couldn't agree more, it would be nice to clean up some of these things.

Personally I would leave REPLACE alone and add a PATREPLACE.
I would also like to see CHARINDEX/PATINDEX changed to have an occurrence parameter, eg find the 2nd occurence of char in string starting from character 10.

On ISNUMERIC, Grant Saunders recently posted a nice little workaround for it.

I'd like also a SPLIT/JOIN function as in VB. So, given a tab/cr limited string the function returns a table and viceversa.
PURGECHAR removes a list of chars from a string.

There's plenty of ways to do the split (or indeed) thing for example a nice CTE way:
http://ole.michelsen.dk/blog/split-string-to-table-using-transact-sql/

Looking at your experience I'm guessing you did know that ;-) but think a built in way would be preferable. The only thing I might say is that the nuances of what you might want to do often vary for such tasks so maybe rolling your own is preferable? To me there may be better candidates for a renewal, I like the cut of Phil's jib on this one.

I really hate the search-y functions in SQL though - I know they are powerful and indeed flexible, but somehow still absolute pony IMHO.

I'd love to see a native Regular Expression support. I sometimes use a CLR for pattern matching, but it's a slow alternative to a natively incorporated function. Using Regular Expressions in pattern matching (and for building new strings from old) would be very powerful.

Top of my list is GROUP_CONCAT, closely followed by REPLACE with wildcards.

Agree with Phil on ISNUMERIC especially -- unbelievable the language doesn't have a working function for this!

ISNUMERIC('-') returns a 1. Discovered that this week (at an inconvenient time no less).

Nasty fast set-based string manipulation functions:
For splitting strings try DelimitedSplit8K or DelimitedSplit8K_LEAD (SQL Server 2012+)
To split strings based on patterns try PatternSplitCM
Need to clean or transform a string? try NGrams, PatExclude8K, PatReplace8K, DigitsOnlyEE, or Translate8K

I cant stress enough the importance of switching from a sequential files mindset to set-based thinking. After you make the switch, you can spend your time tuning and optimizing your queries instead of maintaining lengthy, poor-performing code. -- Itzik Ben-Gan 2001

I would like to see the TRIM available. And why not change ISNULL to work the same way COALESCE does. ISNULL just seems to be more descriptive of what it does, IMHO.
COALESCE by my Webster dictionary means "To grow or come together into one". You are not growing or merging data, you are returning the first not NULL.
