Question

I’ve been assigned the task of changing some data columns in SQL tables (using Sql CE Server 3.5, if that matters).

The tables are populated from hundreds of Comma Separated Excel text documents.

The code makes a stab at determining the data type of the column and the table is created.

Later, I need the ability to come back in and say, “No, this column with ‘Y’ and ‘N’ need to be changed to a Boolean type instead of a Character type.”

I have found information on how to Alter the Table (drop a column and insert the new one), but would I be able to get the table’s column back to the same Column Index value that it had before, like “Insert At Index=X”?

Answer 1

You can just alter the column in place, then you won’t have to worry about ordering it.

ALTER TABLE myTable
ALTER COLUMN myColumn Boolean
