Yes, at least in this case. I found the missing clauses in the standard: <alter column definition> ::= ALTER [ COLUMN ] <column name> <alter column action> <alter column action> ::= <set column default clause> | <drop column default clause> | <add column scope clause> | <drop column scope clause> | <alter column data type clause> | <alter identity column specification> <alter identity column specification> ::= <alter identity column option>... <alter identity column option> ::= <alter sequence generator restart option> | SET <basic sequence generator option> <alter sequence generator restart option> ::= RESTART [ WITH <sequence generator restart value> ] <basic sequence generator option> ::= <sequence generator increment by option> | <sequence generator maxvalue option> | <sequence generator minvalue option> | <sequence generator cycle option> Adriano ------------------------------------------------------------------------------ Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!
