== (equals) operator
Filters a record set for data matching a case-sensitive string.
The following table provides a comparison of the == operators:
| Operator | Description | Case-Sensitive | Example (yields true) |
|---|---|---|---|
== |
Equals | Yes | "aBc" == "aBc" |
!= |
Not equals | Yes | "abc" != "ABC" |
=~ |
Equals | No | "abc" =~ "ABC" |
!~ |
Not equals | No | "aBc" !~ "xyz" |
For further information about other operators and to determine which operator is most appropriate for your query, see datatype string operators.
Performance tips
Performance depends on the type of search and the structure of the data.
For faster results, use the case-sensitive version of an operator, for example, ==, not =~.
