not-exists

问题 Background: For a SPRIDEN_id, sprhold_hldd_code may have one or more of several values or NO values. I need to select SP.SPRIDEN_ID, SP.SPRIDEN_LAST_NAME, SP.SPRIDEN_FIRST_NAME, SR.SHRDGMR_SEQ_NO, SR.SHRDGMR_PROGRAM Where (sh.sprhold_hldd_code = 'RH') does not exist. So far, no records are returned. I have found that if I put a code that is not in the list of possible values (such as Z) in sh.sprhold_hldd_code = 'Z', then it will return results. DATA: (column names abbreviated) SPRIDEN_ID

问题 In this table: |value_id|entity_type_id|attribute_id|store_id|entity_id|value |9289729 |4 |62 |0 |765985 |default value |9289730 |4 |62 |1 |765985 |value in spanish |9289731 |4 |62 |2 |765985 |value in dutch I need to get the value for the store_id (that can be 1, 2 or 3) or the default value (store_id = 0) if it doesn't exist. And it has to be included in a larger query composed of several INNER JOINS, which looks like this so far: SELECT DISTINCT `p2c`.`product_id`, `name_id`.`value` AS

问题 select id from license where not exists( select a.id from license a,version b, mediapart c where c.version_id = b.id and b.cntnt_id = a.cntnt_id and c.is_highdef=1); This query does not gives any rows in result set. Even on using different aliases for the outer license table and the inner one. However, this one using NOT IN works fine: select id from license where id not in( select a.id from license a,version b, mediapart c where c.version_id = b.id and b.cntnt_id = a.cntnt_id and c.is

问题 I have an issue with not exists sql query at w3schools I want to select all customers that work with shipperid = 1 BUT not shipperid = 3 . I tried the following: select o1.customerid, o1.shipperid from orders o1 where o1.shipperid=1 and not exists (select o2.customerid from orders o2 where o1.orderid=o2.orderid and o2.shipperid=3) order by customerid ; The above query gives all customers that work with shipperid = 1 and does NOT exclude customers who work with shipperid = 3 .

问题 To avoid clobbering existing variables, I have code like this window.x = typeof x != "undefined" ? x : {} Which seems like a very long winded way to define something, but necessary to avoid console errors. I tried this out instead, and it seems to work ok. Is it ok to define a variable like this? window.x=window.x||{} Or even in the global scope... x=this.x||{} 回答1: If you use this construct: window.x=window.x||{} And x is defined but has a falsy value (zero, the empty string, null, NaN,

问题 I am currently trying to delete from Table A where a corresponding record is not being used in Table B. Table A has Section, SubSection, Code, Text as fields, where the first three are the Primary Key. Table B has ID, Section, SubSection, Code as fields, where all four are the Primary Key. There are more columns, but they are irrelevant to this question...just wanted to point that out before I get questioned on why all columns are part of the Primary Key for Table B. Pretty much Table A is a

问题 I have many files in a directory A . Some of those files exist in a directory tree with sub-directories B/B1 , B/B2 , B/B3 , B/B4 , ... Note that some files have spaces in their names. For example: in directory A : there's a file named A/red file.png there's another named A/blue file.png and, in directory tree B : there's a file named B/small/red file.png In this example, I would like a script to tell me that the file blue file.png does not exist in the directory B . How can I write a script

问题 I'm trying to show add some filters on my store, but they have a nasty side effect. Suppose I have product type A and B. Now I want to only show A where color = blue/red. $collection = Mage::getResourceModel('catalog/product_collection') ->setStoreId($this->getStoreId()) ->addCategoryFilter($this) ->addAttributeToFilter(array( array('attribute' => 'color', 'in' => array(4, 6)), ) ); This does the trick, but now because product type B has no value assigned to color(since this attribute isn't

问题 My wish is to search docs where field_a exists, and fields_b doesn't exist. Is there a way to do this using the Lucene query syntax in Kibana (Search field in the Discover section of Kibana). I've tried using _missing_:field_b without success ( _exists_ works). I've found this but it doesn't help much: GET /_search { "query": { "bool": { "must_not": { "exists": { "field": "user" } } } } } 回答1: For lucene search syntax: _exists_:field_a AND !_exists_:field_b For elasticsearch search syntax: {
