You can use the following filter options to display specific schemas or objects. Choose Apply Filter after specifying the filters.

In Filter, type one or more letters to display only the objects that have names beginning with those letter or letters. You can also use SQL filter characters for the database that you are using. For example, on some databases, an underscore (_) matches any single character, and the percent sign (%) matches any sequence of characters.

In the text area, type a SQL statement that indicates what data to retrieve from the JDBC data source. Alternatively, drag tables, views, and columns from Available Items to the text area to insert their names in the SQL statement at the insertion point, as shown in Figure 3-2.
For some databases, if a table or column name contains spaces or SQL reserved words, you must enclose the name in quotation marks (" "). If you drag and drop tables and columns, and those items need to be enclosed in double quotation marks, select the Use identifier quoting option. When this option is selected, the data set editor inserts the quotation marks around a table or column name when you drop it in the text area.
