Through the Column Browser, you can use data quality bars and data type information to perform basic review of data across many columns. You can use these tools to select data of interest for display in the data grid or Column Details views or to prompt for suggestions of recipe steps.
You can select one or more columns in the browser and then perform actions on them.
You can apply one or more filters to limit the set of columns displayed in the browser. Click the Filter icon in the Transformer toolbar.
NOTE: Filters are additive and persist between the column browser and the data grid.
For more information, see Filter Panel.
You can manually select one or more columns or apply one of the predefined selections.
At the top of the column browser, you can use the toolbar to quickly build common transformations, filter the display, and other operations. See Transformer Toolbar.
For any individual column:
Click the Eye icon to hide/show of the column in the Transformer page. See Visible Columns Panel.
NOTE: Hidden columns are only removed from view in the Transformer page. They still appear in any generated output.
You can associate a target schema with a recipe. A target schema is information about the column names, data types, and order of the target dataset for which you are trying to build your recipe. For more information, see Overview of RapidTarget.
Actions taken based on the target schema are rendered as new steps in your recipe at the current location.
RapidTarget Panel in Column Browser
In the RapidTarget panel, a target schema that has been associated with your recipe is displayed as an extra set of columns on the left side:
|Left||Column from target|
|Right||Column from source (current recipe)|
Between the two sets of fields are a set of tags that describe the matching between the two columns in the order listed in each dataset. Each tag describes the match found for the corresponding target or source column.
Tip: Mouse over tags that are not solid green to learn the nature of the column mismatch. You can then click the tag to insert steps in your recipe to match the two columns.
|Match by Name||Match by Data Type||Match by Position||Icon||Description|
|No||-||-||Square - red outline|
Target column has no identifiable name match in source. Column appears to be missing from source.
|Yes||No||No||Square - blue outline||Source column name has a matching target column name, but it is in the incorrect location.|
|Yes||Yes||No||Square - green outline||Source column name and data type have a match in the target, but it is in a different position.|
|Yes||No||Yes||Arrow - blue outline||Source column and target column match in name and position, but have different types.|
|Yes||Yes||Yes||Arrow - green solid||Source and target columns match in name, position, and type.|
