Method Detail

escapeLikeExpression

public String escapeLikeExpression(String likeExpression)

Escaping like expressions so wildcards will not be evaluated. The HQL query should have the ESCAPE_EXPRESSION in it's suffix for this to work!!! The method returns an escaped expression, which would behave the same of all SQL repositories when adding escape with the ESCAPE_CHAR to the query. Note: 'like' expression are evaluated differently in MS-SQL. '[]' behaves similar to regex expression and we do handle it specifically in MS-SQL.

Parameters:

likeExpression - The like expression to be escaped.

Returns:

The escaped expression.
