// resetallruns.C
// ==============
//
// This macro resets the values of a column in the table RunProcessStatus. It
// is used by the script filesondisk to reset the values for the columns,
// which indicate the availability of the files.
//
// Usage:
//   .x resetallrun.C+("filename", "column")
// The first argument is giving a file, in which a list of runs can be found
// for which the column will be set to Now() by this macro. The second
// argument is giving the column, which has to be reset.
//
// Make sure, that database and password are corretly set in a resource
// file called sql.rc and the resource file is found.
//
// Returns 0 in case of failure and 1 in case of success.
//
