endswith operator

  • Article

Filters a record set for data with a case-insensitive ending string.

The following table compares the endswith operators using the abbreviations provided:

  • RHS = right-hand side of the expression
  • LHS = left-hand side of the expression
Operator Description Case-Sensitive Example (yields true)
endswith RHS is a closing subsequence of LHS No "Fabrikam" endswith "Kam"
!endswith RHS isn't a closing subsequence of LHS No "Fabrikam" !endswith "brik"
endswith_cs RHS is a closing subsequence of LHS Yes "Fabrikam" endswith_cs "kam"
!endswith_cs RHS isn't a closing subsequence of LHS Yes "Fabrikam" !endswith_cs "brik"

For more information about other operators and to determine which operator is most appropriate for your query, see datatype string operators.

Performance tips

Note

Performance depends on the type of search and the structure of the data. For best practices, see Query best practices.

For faster results, use the case-sensitive version of an operator. For example, use endswith_cs instead of endswith.
