Join Options Dialog Box

You can use the Join Options dialog box to edit the conditions of a catalog pre-join or a query join. This topic describes the options in the dialog box.

Designer displays the Join Options dialog box when you double-click the join icon of the join.

You see the following options in the dialog box:

• Up
  Select to move the specified condition up to a higher level.

• Logical operator drop-down menu
  Specify the logical operator to apply for the specified condition lines. It can be "And", "Or", "And Not", or "Or Not".
• Text boxes
  Specify the objects to define the join condition. It can be a column in the two tables involved in the join, or a parameter or constant level formula in the current catalog data source. You can either select the ellipsis next to each text box to choose an object or type it in the text box. You should reference parameters and formulas in the format @ParameterName or :ParameterName.
• Operator drop-down list
  Specify the operator to compose the join condition.
• =
  Equal to
• >=
  Greater than or equal to
• >
  Greater than
• <
  Less than
• <=
  Less than or equal to
• !=/<>
  Not equal to
• [not] in
  The operator causes an enumerated list of values to appear in the WHERE clause predicate, and is used for evaluating for a true condition. For the operator "in" or "not in", you can use multiple values separated by comma (,).
• [not] like
  The like string pattern matching operator is used to compare the first expression string value to the pattern string (the second expression). If you want to use wildcard character in the pattern string, you can only use "_" and "%".
• [not] between
  The operator allows the system to evaluate whether data values are located between a range of values indicated in the predicate. For the operator "between" or "not between", Designer displays two value text boxes for inputting the same type of values.
• is [not] null
  The operator is used in the WHERE clause predicates to match null values occurring in a specified data field. For the operator "is null" or "is not null", Designer does not display the value text box.
• SQL Statement
  This box displays the SQL statement of the join conditions.
