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 button 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 or not 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
The box displays the SQL statement of the join conditions.
