Query?

Sorry Art, when I look again I have given you bad information here. It is
not possible to perform this at column level with a DELETE. To do this you
will have to use an UPDATE statement, either setting the column to an empty
value ie '' or to NULL (if the column is nullable).

For your information, when you issue a DELETE command in T-SQL, the
statement cannot modify the table structure in any way, it purely effects
the data within it. To alter/remove the columns etc you would need to use an
ALTER TABLE statement.

So this will delete all the entries in ColumnName. I just wanted to make
sure that it won't delete the column itself.

DELETE incl optional WHERE clause:

DELETE ColumnName
FROM YourTable
(WHERE ColumnName = 'YourVal')

UPDATE:

UPDATE YourTable
SET ColumnName = '777'
WHERE ColumnName LIKE '%666%'

By the way, I'm using query analyzer to do this.

I really just want to delete everything in that column but I was also
curious about a "Wildcard" too.

So first, how could I delete all in one column

Second, how can I UPDATE all those that are LIKE '%666%' to '777' ?

Thanks

You want to put update the column no matter what it is?

UPDATE TableName
SET ColumnName = '777'

You could introduce a condition

UPDATE TableName
SET ColumnName = '777'
WHERE whatever = whatever

I tried this on a dead table and it didn't do anything.

What could be used as a wild card for %%?
