You can add patterns to one or more of the analyzed columns to validate the
full record (all columns) against all the patterns, and not to validate each column
against a specific pattern as it is the case with the column analysis. The results chart
is a single bar chart for the totality of the used patterns. This chart shows the number
of the rows that match "all" the patterns.
Warning: Before being able to use a specific pattern with a set of
columns analysis, you must manually set in the patterns settings the pattern definition
for Java, if it does not already exist. Otherwise, a warning message will display
prompting you to set the definition of the Java regular expression.
Before you begin
An analysis of
a set of columns is open in the analysis editor in the
perspective of Talend Studio.
Select the check boxes of the expressions you want to add to the
selected column, then Click OK.
The added regular expressions display under the analyzed columns in
the Analyzed Columns view and the
All Match indicator is displayed in the Indicators list in the Indicators view.
