Message Text |
The %S_MSG '%.*ls' on table '%.*ls' has %d column names in %S_MSG key list. The maximum limit for index or statistics key column list is %d. |
Explanation
The key column list for the specified index or statistics exceeds the maximum number of columns allowed.
User Action
Modify the key column list to include no more than the specified maximum number of columns.
For nonclustered indexes, consider using the INCLUDE clause in the CREATE INDEX statement to add columns to the index as nonkey columns. This method avoids exceeding the current index size limitation of a maximum of 16 key columns. For more information, see Index with Included Columns.
