List only bit fields?

In SSMS, i'm trying to list only the columns in a table that are bit fields. Reason being, there is a checkbox in our front end app that the customer wants "checked" (or set to '1') by default. Our engineers do not have a mapping that shows which sql field is mapped to that checkbox in their Delphi front end, and they are less than cooperative in providing the dba's with the info we need to get our job done, so we're left to use process of elimination go one by one and set the default values in sql to '1' until we see that box "checked" in the app. It would expedite things for me if i could produce a list of the bit fields in the tables that i suspect hold that column. Can this be done?

Second question: What's the best way to poison the coffee of an engineer without getting traced back to me?

select * from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME = 'tableName' and DATA_TYPE = 'bit'

[code]SELECT * FROM INFORMATION_SCHEMA.[COLUMNS] WHERE DATA_TYPE = 'bit'[/code]As for your second question, Siri has a brilliant answer, which I leave as an exercise to the reader.

i think your second question is easier than the first.

the key is to use the command in red


SET TRACE OFF

UPDATE CUP
SET    COFFEE = COFFEE + POISON
WHERE  OWNER  = 'ENGINEER'

SET TRACE ON

select 'alter table ' + TABLE_NAME + ' alter column ' + COLUMN_NAME + ' bit default(1)' from INFORMATION_SCHEMA.COLUMNS where DATA_TYPE = 'bit'
