How to check whether a column is autoincrement

    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
