Looking for a damn-handy SQL parser in VBA

Does anyone have any code from a prior project that edits SQL statements?
------
I have a graph that's table-driven, where one of the fields is the SQL string. An example is...

SELECT tbl_time.txt_time_month_year AS [Month], tbl_indicators_data.sng_idata_value_1 AS [ALCOA]
FROM tbl_time INNER JOIN tbl_indicators_data ON tbl_time.lng_id = tbl_indicators_data.lng_month_id
WHERE tbl_indicators_data.lng_indicator_id = 32
ORDER BY tbl_time.lng_month_ID ASC;

The above SQL displays a graph with all values.

I have a business need to allow the user to edit the above to allow FROM and TO dates, like (note the WHERE-BETWEEN CLAUSE)...

SELECT tbl_time.txt_time_month_year AS [Month], tbl_indicators_data.sng_idata_value_1 AS [ALCOA]
FROM tbl_time INNER JOIN tbl_indicators_data ON tbl_time.lng_id = tbl_indicators_data.lng_month_id
WHERE tbl_indicators_data.lng_indicator_id = 32 AND tbl_time.lng_month_ID BETWEEN 200201 AND 200312
ORDER BY tbl_time.lng_month_ID ASC;

I can hack the big components of SQL okay, but getting the 'AND tbl_time.lng_month_ID BETWEEN 200201 AND 200312' clause is proving to be a pain.

Points given generously for anything I can build on.

TIA -Jim

(1) I have my dates formatted as longs in yyyymm format, since this is accounting summary stuff and everything is a month.
(2) In SQL code I'm reading the data, populating FROM and TO combobox.rowsources, and displaying the first and last months as the values.

Pretty damn slick if I do say so myself.

My problem is, every time I alter the SQL I need to read the existing SQL, determine if there's an existing BETWEEN clause (somewhat tough), if so wipe it out, and write a replacement (fairly easy).

Perhaps I'll include the BETWEEN clause in every SQL statement, even if it's redundant, just to make user changes like this easier.

Resolved it by re-writing the entire WHERE clause every time, instead of trying to hack multiple WHERE critera.

Wow. <sniff> You were the only one that cared...

You should have asked an easier question, like "How do I make my form go beep"...:-)

Still not entirely sure why you're dynamically change the WHERE clause though - there must be an easier way?

Don't tempt me... if there's a mad push for points, I can ask all sorts of silly questions...
