I need to filter out the Gemfire region based on date the query is
String queryString = SELECT * FROM /exampleRegion WHERE prcs_date =DATE $1;
QueryService queryService = cache.getQueryService();
Query query = queryService.newQuery(queryString);
Object[] params = new Object[1];
params[0] = "2018-05-03";
SelectResults results = (SelectResults)query.execute(params);
when i tried to execute it I am getting the following exception
QueryInvalidException: Syntax error in query: expecting StringLiteral, found '$'
But when I tried to run the hardcoded query select * from /exampleRegion where prcs_date= DATE '2018-05-03' I am able to get the results
I think the correct way to translate a string to a date is to use the to_date function. Here's an example:
SELECT * FROM /exampleRegion WHERE prcs_date = to_date($1, 'yyyy-MM-dd')

I have the following C# code to select a column from a table that is on a linked server:
var query2 = $#"select [FileName] from [AMS_H2H].[H2H].[dbo].[FileReconciliation] where ProductCode = #productCode";
LayZConnection(); //make the db connection
var candidates = _dbConnection.Query<int>(query2, new { productCode = "ACHDH" });
When running it, I get the following error:
"Input string was not in a correct format."
If my query is instead the following, where I select all columns, it works:
var query2 = $#"select * from [AMS_H2H].[H2H].[dbo].[FileReconciliation]
What is the correct format to select just the FileName. Btw, the first query works fine from MSSMS.
You're specifying a type of int in Query<int>, which will cause Dapper to try and map the result of the query to an integer, however your query is returning a filename in select [FileName], which would suggest that it is a string.
Changing the type Query<string> should solve the issue.
More information on Dapper's Query method is available in Dapper's documentation
I'm looking at doing some report development for one of our Training softwares. I finally got some queries working in FB Maestro, as I'm only familiar with SQL and Oracle.
I have the following query that works and returns results, but when trying to set up a parameter for the display name, the query runs (at least it returns no errors) however the dataset does not return any data. Has anyone worked with these before?
Here's the query:
Select CertStatus, DisplayName, Count(CertStatus) From ( With cte as (Select * From (Select COURSEVERSIONSWITHAGGREGATES.CourseTitle, COURSEVERSIONSWITHAGGREGATES.CourseNumber, "MaxTrainedCompletionDate", "Course_ID", PersonnelView.DISPLAYNAME, COURSEVERSIONSWITHAGGREGATES.RecertificationValue, COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONUNIT_ID,
CASE
WHEN COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONUNIT_ID = 3 THEN DATEADD(year, 1*COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONVALUE, MaxTrainingView."MaxTrainedCompletionDate")
WHEN COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONUNIT_ID = 2 THEN DATEADD(month, 1*COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONVALUE, MaxTrainingView."MaxTrainedCompletionDate")
WHEN COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONUNIT_ID = 1 THEN DATEADD(week, 1*COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONVALUE, MaxTrainingView."MaxTrainedCompletionDate")
WHEN COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONUNIT_ID = 0 THEN DATEADD(day, 1*COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONVALUE, MaxTrainingView."MaxTrainedCompletionDate") END
AS ExpirationDate
From MAXTRAININGVIEW
INNER JOIN PERSONNELVIEW ON (MAXTRAININGVIEW."Personnel_ID" = PERSONNELVIEW.PERSONNELID) INNER JOIN COURSEVERSIONSWITHAGGREGATES ON (MAXTRAININGVIEW."Course_ID" = COURSEVERSIONSWITHAGGREGATES.COURSEID)
WHERE Personnelview.DisplayName = 'Aaron')) Select CourseTitle, CourseNumber, "MaxTrainedCompletionDate", "Course_ID", DisplayName, RecertificationValue, Recertificationunit_ID, ExpirationDate,
CASE WHEN ExpirationDate > current_date Then 'Active' WHEN ExpirationDate < current_date Then 'Expired' END As CertStatus from cte) Group By CertStatus, DisplayName
This returns values with the static value of 'Aaron' in report builder. But trying to use a parameter, it does not throw an error in report builder, however it just does not return any data.
For example this:
WHERE Personnelview.DisplayName = '#DisplayName'))
I've got the parameter based off another data set query, and that seems to work (it gives me the option to select employees)
Here is an example of it passing 'Aaron' (with personal info removed)
Example of passing #FName Parameter:
If you want to pass the parameter in report, other type database might not recognize query like "where [field] in #parameter", so I think you could try to use filter to achieve this goal(create a filter in dataset, and create a parameter, then specify it in filter properties).
I am trying to update sum of particular amount from one table as a value in another table, but getting problem when the particular id does not exist in another table :
the hql i have looks like beow:
var session = SessionManager.GetCurrentSession();
var queryString = string.Empty;
queryString += #"update CLiner cl set cl.UnbilledDue =
(select sum(cu.UnbilledAmount) as UnbilledAmount from CUnbilled cu
where cu.AccountNo = cl.AccountNo and cu.FileDate = :fileDate)
where cl.FileDate = :fileDate ";
var query = session.CreateQuery(queryString);
query.SetDateTime("fileDate", new DateTime(2014, 10, 7));
query.ExecuteUpdate();
but its giving exception when the particular account no does not exist in child table and the sum is returned as zero.
i tried changing the subquery select to
select isnull(sum(cu.UnbilledAmount),0) as UnbilledAmount
which as expected is not supported by nhibernate hql. so there a way i can convert null to zero in hql select statement...
Try this:
coalesce(sum(cu.UnbilledAccount), 0)
Reason:
Normally when you wirte a SQL query to prevent NULL you must apply an ISNULL function over the SELECT, in this way:
ISNULL(SELECT sum(...., 0) or COALESCE(SELECT sum(...., 0) (return the same result but COALESCE can applied with more parameter, ISNULL has only two parameters)
but in HQL isn't possible, so you can use COALESCE function to prevent that behaviour.
I have this query :
$query = mysql_query ("SELECT *
FROM saledb.application
WHERE app_id = (
SELECT app_id
FROM saledb.applicationdetails
WHERE is_hot = '1'
) LIMIT $Kvet,$Zet
");
And I have the following error:
Unable to save result set in
/home/lemondo/lemondosales.itnovations.ge/content/tpl/gtpl/main.php on
line 68
When I changing select item with MAX(app_id) it works but i need show all results. i know where is problem mysql cant choose in one query meny ID but i need alternativ query.
Use the IN predicate instead of = like os:
SELECT *
FROM saledb.application
WHERE app_id IN
(SELECT app_id
FROM saledb.applicationdetails
WHERE is_hot = '1');
$query = mysql_query ("SELECT * FROM saledb.application WHERE app_id IN (SELECT app_id FROM saledb.applicationdetails WHERE is_hot = '1') LIMIT $Kvet,$Zet");
That should do the trick. If you leave '=' and the subquery returns more than one row, you wil get that error. To match all the lines in saledb.application that have the app_id in the result set you need to use "IN" :)
This is the only place that I get all answer ;)
I want to select :
SELECT
RTRIM(LTRIM(il.Num_bloc)) AS Bloc,
RTRIM(LTRIM(il.num_colis)) AS Colis,
cd.transporteur AS Coursier,
cd.origine AS Origine,
cd.destination AS Destinataire,
cd.adresse AS [Adresse Destinataire],
cd.poids AS Poids,
il.Signataire, il.num_cin AS CIN, il.date_livraison AS [Date Livraison]
FROM
dbo.cd
INNER JOIN
dbo.il ON cd.bloc = il.Num_bloc AND dbo.cd.colis = dbo.il.num_colis
WHERE
(il.Num_bloc = RTRIM(LTRIM(#ParamBloc)))
AND (il.num_colis = RTRIM(LTRIM(#ParamColis)))
In the way of getting result if the user put ether #ParamBloc or #ParamColis
Try using IsNull() function.
A simple query would go like this
Select * from yourTable
Where
Num_bloc = ISNULL(#ParamBloc, Num_block) AND
num_colis = ISNULL(#ParamColis, num_colis)
The second parameter would make the expression to true if the #parameter Bloc or Colis is null. This query would be useful for all 4 possible combination of these two parameter.
