Nervosa About SOQL query and date comparing.
Greetings to everybody out there!
So here is the question. There is a SOQL query that being formed like this:
date mysearchdate=date.valueOf(searchDate);
string sortFullExp = sortExpression + ' ' + sortDirection;
if(searchText != null) {
searchstr = 'WHERE Name LIKE \'%' + searchText + '%\' order by ';}
if(searchDate != null) {
searchstr = 'WHERE Name LIKE \'%' + searchText + '%\' and CreatedDate >=: mysearchdate order by ';}
items = Database.query('Select id, Name, Item_Price__c, CreatedDate from Item__c ' + searchstr + sortFullExp);Well, the main problem is in this -
CreatedDate >=: mysearchdate
part of code. It doesn't work when i need to perform accurate comparison:
CreatedDate =: mysearchdate
Why?
Thanks in advance.
Finally I've found an answer! It is SOQL function DAY_ONLY()
date mysearchdate=date.valueOf(searchDate);
string sortFullExp = sortExpression + ' ' + sortDirection;
if(searchText != null) {
searchstr = 'WHERE Name LIKE \'%' + searchText + '%\' order by ';}
if(searchDate != null) {
searchstr = 'WHERE Name LIKE \'%' + searchText + '%\' and DAY_ONLY(CreatedDate) =: mysearchdate order by ';}
items = Database.query('Select id, Name, Item_Price__c, CreatedDate from Item__c ' + searchstr + sortFullExp);

Well, I guess it's all because of datetime format of system field CreatedDate - it is different with mysearchdate. So here is one more question - can I compare just Day, Month and Year?
