Grails包括可搜索查询构建器中的空值检查

Question

We are using grails 2.1.1 and searchable - 0.6.3

We are trying to filter results using query builder . Our problem is that we cannot put a check on tupples having null in a field. We have gone through lots of documentation but couldn't find any solution.

Is there a way to put a null value check using query builder in grails searchable plugin .

using

mustNot(term('columnName',null))

or

mustNot(term('columnName','null'))

does not work.

Answer 1

Try this:

mustNot(gt("columnName", 0))
