# 3320 Dropping a Column and Altering a Constraint in Same ALTER TABLE Statement Can Corrupt Tables

Executing the following SQL results in the error:

The column 882 does not exist in the table JaarBegrotingsregels

and afterwards the table cannot be opened (error #100).

ALTER TABLE "JaarBegrotingsregels"
ALTER CONSTRAINT "Primary" AS UNIQUE ("JaarInstellingID","Periode","Soort"),

Comments Comments
The problem with the opening of the table afterwards was due to the fact that the table files did not match the catalog file. You can always restore any prior version of the catalog (.edbcat) or table files (.edbtbl, .edbidx, .edbblb, .edbpbl) from their .old versions in order to correct an issue like this.
