DEFAULT clause in ALTER TABLE statement resulting in syntax error
I am trying to execute the following statement using a SQL query within MS Access;
ALTER TABLE [table] ALTER COLUMN [column] SET DEFAULT 'default value'
However, I get a dialog displaying the error Syntax error in ALTER TABLE statement.
And when I click OK it highlights the word DEFAULT
. I also tried the following statement;
ALTER TABLE [table]
ADD CONSTRAINT [Default] DEFAULT 'default value' FOR [column]
And I get another error Syntax error in CONSTRAINT clause.
What is the correct syntax for setting a default value in MS Access? The db file is Access 2003 format.
Support for DEFAULT
was included in Access DDL with Jet 4 (Access 2000). However it can only be used in DDL executed from an ADO connection.
This worked with Access 2007.
CurrentProject.Connection.Execute "ALTER TABLE MyTable " & _
"ALTER COLUMN field2 SET DEFAULT ""foo"";"
Note if your db file is Access 97 or earlier, you won't be able to set a field DEFAULT
value from DDL.
