Create column

S

What is the code to create a new column to an existing table. I don't want to
manually create a column in the design view, I want the create or update
statement.

Yes, it is possible. Just use a Data Definition Query

- Create a new query, but don't add any tables.
- On the Menu Bar, select Query | SQL Specific | Data Definition
- Write your query to modify the table, using the ALTER TABLE syntax.

For example: "ALTER TABLE Tablename ADD COLUMN NewField TEXT(25);"

For more information about writing an ALTER TABLE query, search Help.

You could also use DAO or ADO to do this programmatically:

If you do some digging in the MS Knowledge Base or in other sources you
should be able to find some examples for doing this in ADO.

Hope that helps!

Click to expand...

ALTER TABLE tablename
ADD COLUMN newcolumname
datatype(size);

where datatype is YESNO, COUNTER, CURRENCY, DATETIME, SHORT, LONG,
SINGLE, DOUBLE, TEXT, MEMO, or OLEOBJECT and Size is the optional size
of a Text field.
