Specify a hit count

  • Artikkeli

Applies to: SQL Server

A breakpoint hit count is a counter that the Transact-SQL debugger increments each time the breakpoint is reached. If the specified hit count is reached and any specified breakpoint condition is satisfied, the debugger performs the action specified for the breakpoint.

Hit count considerations

By default, execution breaks every time a breakpoint is hit. You can choose between the following options:

  • Break always (the default)
  • Break when the hit count equals a specified value
  • Break when the hit count equals a multiple of a specified value
  • Break when the hit count is greater than or equal to a specified value

Breakpoint hit counts are incremented within the scope of a debugging session. All hit counts are set to zero at the start of each debugging session.

To track the number of times a breakpoint is hit, without breaking execution, specify a hit count with a high value so the breakpoint never breaks.

The default action for a breakpoint is to break execution when both the hit count and breakpoint condition are satisfied. For information about specifying other actions, see Specify a breakpoint action.
