  Dear all,

  I have the following select statement:

  SELECT (column_name +' '+'('+data_type+ ' '+IsNull(CAST(character_maximum_length as varchar(5)), '')+')') AS columnInfo FROM INFORMATION_SCHEMA.COLUMNS WHERE (TABLE_NAME = 'test') ORDER BY COLUMN_NAME

  How can i select only the columns that are not autoincrement?

  Thanks in advance.

  the views from INFORMATION_SCHEMA stuff are missing a lot of info;

  to get theidentity or not,i would either use the ColumnProperty() function, or select from sys.columns instead.

  select * from sys.columns where is_identity=0

  select object_name(id),name,columnproperty(id,colid,'IsIdentity') from syscolumns
