SUMMARY
=======

If you upsize a table that contains a field with a default value that is the
value of another table's field value, you will receive an error 128. This
article explains how to create a default column value on SQL Server.

MORE INFORMATION
================

A default value for a column in SQL Server cannot reference the names of any
columns or other database objects. The default value must contain a valid
expression. For example, if you want to create a default value for a column
called State so that each new entry would use the default value WA, use the
following program:

     * Connect to a SQL server using a predefined datasource.
     xhandle = SQLCONNECT(DataSourceName, cUserID, cPassword)
     IF xhandle > 0
        WAIT WINDOW "Successful Connection. Handle = " + STR(xhandle)
     ELSE
        WAIT WINDOW "Bad connection"
        =errhand()
        RETURN
     ENDIF

     * Use the appropriate database.
     x = sqlexec(xhandle,"use pubs")
     IF x < 0
         =errhand()
         RETURN
     ENDIF

     * Create the default.
     x = SQLEXEC(xhandle,"create default mystate as 'WA' ")
     IF x < 0
        =errhand()
        RETURN
     ENDIF

     * Run a stored procedure to bind the default "mystate" to a
     * specific column.
     x = SQLEXEC(xhandle,"sp_bindefault mystate, 'authors.state' ")
     IF x < 0
       =errhand()
       RETURN
     ENDIF

     * Each new row inserted will contain the value 'WA' for authors.state
     * if a value is not supplied.

     * Disconnect
     x = SQLDISCONNECT(xhandle)
     IF x < 0
        =errhand()
        RETURN
     ENDIF

     PROCEDURE errhand
       =AERROR(myerror)
       CLEAR
       ? 'An error has occurred.'
       FOR n = 1 to 7
         ? myerror(n)
       ENDFOR
       = SQLDISCONNECT(xhandle)
     RETURN
