Browsing debug information


Use tabs at the bottom of the debugger window to view miscellaneous debug information.

 

 

Parameters and Variables

This tab displays the list of procedure input and output parameters and variables (distinguished by respective icons) with their values and types.

 

Procedure Debugger - Debug info - Parameters and Variables

 

 

Double-click an item in the list to call the Modify Variable dialog allowing you to set the parameter/variable value.

 

Procedure Debugger - Debug info - Parameters and Variables - Modify Variable

 

 

Use the edit control to specify a value for the variable, or select the CheckBox Null option.

 

The controls vary according to the data type of the variable being edited:

  • for integral data types (SMALLINT, INTEGER), use the spinner control to specify the necessary value
  • for floating-point data types (FLOAT, NUMERIC, DOUBLE PRECISION, DECIMAL), type in or click the arrow-down button to call the Calculator popup window and set the necessary value
  • for string data types (CHAR, VARCHAR), use the editable area to input the necessary text
  • for temporal data types (DATE, TIME), type in or click the arrow-down button to call the Date editor popup window and set the required date value

 

 

Watches

Use this tab to manage watches for parameters and variables declared in the procedure being currently debugged.

 

Procedure Debugger - Debug info - Watches

 

 

The Watches list provides the following attributes of each parameter/variable of the procedure:

Name

Address (the name of the procedure to which the parameter or variable belongs)

Value

Type

Kind

 

Right-click an item in the list to call the context menu allowing you to select watches using the Add Watch dialog, to delete the selected watch, or to delete all watches.

 

The Add Watch dialog allows you to select the parameters and variables to add watch for.

 

Procedure Debugger - Debug info - Watches - Add Watch

 

 

To select a parameter/variable, you need to move it from the Available list to the Selected list. Use the Move all to Selected Move to Selected Move to Available Move all to Available  buttons or drag-and-drop operations to move the parameters and variables from one list to another.

Address (the name of the procedure to which the breakpoint belongs)

Line (the line number where the breakpoint is set)

Condition

Eval expression

Passes (the number of times the execution has already passed through the breakpoint)

 

Right-click an item in the list to call the context menu allowing you to enable/disable, to specify properties using the Breakpoint Properties dialog, to delete the selected breakpoint, or to delete all breakpoints.

 

The Breakpoint Properties dialog allows you to view/edit properties for each breakpoint set in the procedure.

 

Procedure Debugger - Debug info - Breakpoints - Breakpoint Properties

 

 

Conditions

 

Condition

This field should contain the correct SQL statement returning a boolean value. The execution will stop at this breakpoint if the statement is true, and skip the breakpoint if it is false.
