• Or

• <

• <=

• [not] in
  Causes an enumerated list of values which will appear in the WHERE clause predicate to be evaluated for a true condition. The [not] in operator supports multi-value parameters as the value.
• [not] like
  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, only "_" and "%" are supported.
• [not] between
  Allows the system to evaluate whether or not data values are located between a range of values indicated in the predicate. For operator ‘between' or ‘not between', there are two value input boxes for inputting the same type of values.
• is [not] null
  It is used in WHERE clause predicates to match null values occurring in a specified data field. For operator ‘is null' or ‘is not null', the value input box is hidden.

Value

Specifies the value of how to filter the field. You can either type in the value manually or click next to the text box to specify the value.

When you type in the value, if multiple values are required, they should be separated with ",", and if "," or "\" is contained in the values, write it as "\," or "\\".

When you click to specify the value, the Expressions dialog is displayed. The following are options in the dialog:

• Real Name tab
  Lists the tables added in the query on which the dataset is created with all their columns, also the formulas and parameters in the catalog. Double-click the required field to add it as the value.

  The following symbols at the bottom of the Expressions dialog allow you to modify the expression according to your requirements.

  • +
    Adds numbers or fields together.
  • -
    Subtracts numbers or fields together.
  • *
    Multiplies numbers or fields together.
  • /
    Divides numbers or fields together.
  • =
    Equates fields together.
  • "
    Places quotations on long character strings or name that have blanks in them. For example, you should place quotes on values such as "New York" or "Washington DC".
  • ||
    Places fields together in the same expression. For example, "New York" || "Washington DC".
  • ( )
    Places the fields in parentheses.
• Field Value tab
  Lists all column names of the related table, in which the field to be filtered is. Check the column name of the field to be filtered, click OK, then the values of the field will be displayed. Choose the required value and click Set to use it to filter the field.
