When you execute a DBCC CHECKTABLE statement, the command may fail and the following error message occurs:
[Microsoft][ODBC SQL Server Driver][Named Pipes]ConnectionCheckForData (PeekNamedPipe()).
[Microsoft][ODBC SQL Server Driver][Named Pipes]Connection broken.
The error message occurs only if the following conditions are true:
  • A DBCC CHECKTABLE statement is executed on a table.
  • There are text or image columns in the table.
  • The clustering key for the table is at least 400 bytes long.


To work around this problem:
  1. Script out all the objects from the affected database.
  2. Create a new database, and then execute the scripts from step 1 to create all the tables and other database objects.
  3. Use the bcp utility to copy the data out into flat files. Use the bcp utility to copy the data from the flat files into the scripted database that you created in step 2.
  4. Drop all the AUTO_CREATE_STATISTICS indexes from the new database.
