In a model based on a SAS target server, you use the SAS tab in the Table Column Editor to manage the data type, null option, and other properties for the selected column.
Note: The options described here are the basic options available for most physical data types. There can be more options available depending on the physical data type you assign to the table column. We recommend that you refer to your SAS documentation for more information about using these properties.
To define SAS table column properties
The SAS Table Column Editor opens.
Note: Click New on the toolbar to create a new column. Use the Enter filter text box to filter a very large list of columns to quickly locate the one that you want to define.
Lets you select a data type from the drop-down list to apply to the selected column. If the selected data type requires a value for precision, scale, or both, enter the value inside the data type parentheses. For example, you can select the DECIMAL() data type and specify a precision of 2 and a scale of 10 inside the parentheses to assign the data type DECIMAL(2,10) to the selected column.
Lets you specify a null option for the selected column.
Lets you enter the estimated percentage of nulls used for that column if the option is available. For example, you can estimate a variable width ADDRESS 2 column assigned a width of 50 characters, to be NULL about 30 percent of the time. Use whole numbers. You can later use the Volumetrics dialog to calculate table and database size estimates based on these and other values.
Lets you enter the SAS display format information for column data output.
Lets you enter a name that identifies the column values in SAS applications. By default, the column name with a colon appended is inserted (for example, customer_name:).
Lets you enter the SAS display informat information used for reading column data.
Lets you enter the name that designates the SAS database.
SAS table column properties are defined and the SAS Table Column Editor closes.
