Filters a record set for data that does not have a case-sensitive ending string.
has searches for indexed terms, where a term is three or more characters. If your term is
fewer than three characters, the query scans the values in the column, which is slower than looking up the term in the term index.
The following table provides a comparison of the
||RHS is a term suffix in LHS||No||
||RHS isn't a term suffix in LHS||No||
||RHS is a term suffix in LHS||Yes||
||RHS isn't a term suffix in LHS||Yes||
The following abbreviations are used in the table above:
* RHS = right hand side of the expression * LHS = left hand side of the expression
For further information about other operators and to determine which operator is most appropriate for your query, see datatype string operators.
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,
If you're testing for the presence of a symbol or alphanumeric word that is bound by non-alphanumeric characters at the start or end of a field, for faster results use
- T - The tabular input whose records are to be filtered.
- Column - The column to filter.
- Expression - Scalar or literal expression.
Rows in T for which the predicate is
