Copy selection to clipboardThis tab allows to compare text definition of database objects or text column values:
Vertical toolbar between two panels contains additional tab-specific actions:
Open Data diff for the current table/view
Open Data diff for the current table/view filtered only to new and changed records
Ignore case
Ignore leading and trailing whitespaces
Ignore all whitespaces
Ignore empty lines
Show tab and space characters
Show line numbers
Word wrap
Refresh diff (Ctrl+R), available only for editable object types (modules and form/report module-only view), active only if left or right panel is in the edit stateThe state of Show tab and space characters and Show line number toggles is common for the Text diff tab and other tabs having bottom text preview (Object list, etc.).
Main text area highlights new and changed lines (whole line highlighted), bottom panel shows selected line with per-character changes highlighted. Top panel shows text changes summary: total number of rows, new, changed, new+changed and unchanged line counts. Note that when you change text comparison options like ignore case or white spaces - changes highlight and new/changed totals can be changed because of different text comparison rules.
You can filter text lines to show only new, changed or new+changed lines. In this case most of the unchanged lines are collapsed and can be shown/hidden using the +/- buttons to the left of the text area. Number of unchanged lines shown by default is configured in ADD.LINES field in the right-top corner.
When Word wrap is enabled, horizontal scrolling is disabled, as it is no longer needed in this mode. To maintain visual alignment of wrapped lines between the two sides of the diff, the opposite line may be padded with a number of non-breaking space (NBSP) characters. These characters are not shown in Show tab and space characters mode, but will be present when selecting and copying text. In rare cases, word wrapping may cause the number of visual lines to differ between the two sides of the diff. If this disrupts readability, it is recommended to disable Word wrap for such texts.
For table data value each text changes summary panel contains buttons to manage the edit state:
Edit - enter in the Edit mode
Save edit changes to the database, opens Execute script dialog that will contain SQL script with desired action.
Cancel edit changes and reset text like it was before any edits, additional confirmation dialog shown.
