!endswith_cs operator

Filters a record set for data that doesn't contain a case-insensitive ending string.

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

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.
