Tip of the Day: New Rule Notification for Dropped Columns
Product.......: R:BASE X.5 and R:BASE X.5 Enterprise (Version 10.5)
Build.........: 10.5.4.20421 or higher
Sections......: Data Designer
Keywords......: Rule, Column, Table, Warning
Did you know that a notification will now appear after a column is
dropped from a table, where a rule is defined for that column?
After dropping a column, the rules are now checked. If a rule for the
table becomes invalid, an error message about the now dropped column
will be displayed, similar to the message when a table/view is
dropped and a view is dependent on that dropped table/view.
A rule is a condition placed upon a column, which R:BASE checks
during data entry to ensure that the data meets specific criteria.
Rules can be created with predefined options, or with custom rules.
Rules can be set to work with data entry and data deletion. A data
entry rule ensures that the data entered into a column meets the
criteria you specify. A data deletion rule ensures that data deleted
in a column also meets specified criteria.
When you enter/edit or delete data, R:BASE checks the data with the
corresponding rules. If the conditions of a particular rule are not
met, R:BASE displays the error message defined for that rule. Rules
can even be set to fail to meet conditions, and otherwise, R:BASE
displays the error message defined for that rule.
Rules may be turned ON and OFF on demand with the RULES setting.
Syntax.: SET RULES ON/OFF
Default: ON
SET RULES determines whether R:BASE checks data against all existing
rules during data entry and modification when you use the EDIT, EDIT
USING, ENTER, INSERT, LOAD, or UPDATE commands, or the import/export utility.
Very Best R:egards,
