I think some char is missing?
Thanks and regards!
Your query variable length is not sufficient, modify it as below. Also, schema name can accept only certain characters, colon is not allowed I guess.
declare #query NVARCHAR(max)
I'm using tSqlt to unit test a stored procedure. This stored proc joins to a table-valued function, the function takes no parameters and the results are filtered via the join on clause.
I'm writing multiple tests for the stored proc. Is there a way to to fake the function in such a way that I could return different results based on the test that is being run.
The only solution I can think of is to create a fake per test, which is possible but a little more than clunky.
I imagine an ideal solution would be some sort of variable exposed in tsqlt that would allow me to determine which test I'm in and use some sort of case statement or something.
I use following procedure for that. It is not ideal, but working:
CREATE PROCEDURE [tSQLt].[FakeFunction2]
#FunctionName VARCHAR(200)
, #SchemaName VARCHAR(200) = 'dbo'
, #tmpTableName VARCHAR(200)
AS
BEGIN
DECLARE #Params VARCHAR(2000);
DECLARE #NewName VARCHAR(MAX) = #FunctionName + REPLACE(CAST(NEWID() AS VARCHAR(100)), '-', '');
DECLARE #FunctionNameWithSchema VARCHAR(MAX) = #SchemaName + '.' + #FunctionName;
DECLARE #RenameCmd VARCHAR(MAX) = 'EXEC sp_rename ''' + #FunctionNameWithSchema + ''', ''' + #NewName + ''';';
DECLARE #newTbleName VARCHAR(200) = #SchemaName + '.tmp' + REPLACE(CAST(NEWID() AS VARCHAR(100)), '-', '');
DECLARE #newTblStmt VARCHAR(2000) = 'SELECT * INTO ' + #newTbleName + ' FROM ' + #tmpTableName;
EXEC tSQLt.SuppressOutput #command = #newTblStmt;
SELECT #Params = p.params
FROM
( SELECT DISTINCT ( SELECT p1.name + ' ' + type1.name + b.brk + ',' AS [text()]
FROM sys.types type1
JOIN sys.parameters p1 ON p1.system_type_id = type1.system_type_id
CROSS APPLY
( SELECT CASE WHEN type1.name LIKE '%char' OR type1.name = 'varbinary' THEN
REPLACE(
'(' + CAST(p1.max_length AS VARCHAR(5)) + ')', '-1', 'MAX')
WHEN type1.name IN ('decimal', 'numeric') THEN
'(' + CAST(p1.precision AS VARCHAR(5)) + ', '
+ CAST(p1.scale AS VARCHAR(5)) + ')'
WHEN type1.name IN ('datetime2') THEN
'(' + CAST(p1.scale AS VARCHAR(5)) + ')'
ELSE ''
END AS brk) b
WHERE p1.object_id = p.object_id
ORDER BY p1.parameter_id
FOR XML PATH('')) [parameters]
FROM sys.objects AS o
LEFT JOIN sys.parameters AS p ON p.object_id = o.object_id
LEFT JOIN sys.types AS t ON t.system_type_id = p.system_type_id
WHERE o.name = #FunctionName AND o.schema_id = SCHEMA_ID(#SchemaName)) [Main]
CROSS APPLY
(SELECT LEFT(Main.[parameters], LEN(Main.[parameters]) - 1) params) AS p;
EXEC tSQLt.SuppressOutput #command = #RenameCmd;
DECLARE #newFunctionStmt VARCHAR(MAX) = '';
SET #newFunctionStmt = 'CREATE FUNCTION [' + #SchemaName + '].[' + #FunctionName + '](' + COALESCE(#Params,'') + ')';
SET #newFunctionStmt = #newFunctionStmt + ' RETURNS TABLE AS RETURN (SELECT * FROM ' + #newTbleName + ');';
EXEC tSQLt.SuppressOutput #command = #newFunctionStmt;
END;
and usage:
INSERT INTO #table
(col1
, col2
, col3)
VALUES
('a', 'b', 'c'),
('d', 'e', 'f');
EXEC tSQLt.FakeFunction2 #FunctionName = 'function_name'
, #SchemaName = 'dbo'
, #tmpTableName = '#table';
now with any passed parameter to that function it will always return the values from #table temp table
I thought of one potential solution.
I create a table within the test class schema and populate it with the results I wish to be returned per test.
CREATE TABLE testcalass.fakefunction_Results
(
ID INT,
Value NUMERIC(12, 5)
)
GO
CREATE FUNCTION testcalass.fakefunction()
RETURNS #results TABLE
(
ID INT,
Value NUMERIC(12, 5)
)
BEGIN
INSERT INTO #results
SELECT ID, Value FROM testcalass.fakefunction_Results
END
GO
So basically, I can populate is functions results at the top of my tests during the assemble section.
I am writing a report based on parameters, utilizing a sql stored procedure. Problem is there are several 'optional' parameters, where the user can choose a value, or ignore that parameter altogether. I need to use the stored proc as a dataset in asp.net report. Only way I thought of doing it is to create a table from the results. But I'm clueless.
How do I turn this into a 'create table' stored proc?
Any assistance is greatly appreciated.

Rahul: as per you answer I updated like this but it still gives error......
set #query = #query + ' pivot(sum(cast(MarksObtained as int)) for Subject_Name in (' + #subjects + ')) as pvt'
I think it gives error because I am using the MarksObtained column (as varchar(10))...plz give me a suggestion how I can convert varchar to int so that summation of total MarksObtained can be done.
You can convert like this way:
SUM (CONVERT(int,<your varchar column>))
This will work if your varchar column actually holds numeric value. Otherwise, you can try casting it using cast function like:
sum(cast(varchar_column as int))
EDIT:
Created a sample table with just 2 column (name and marksobtained), both of type varchar(10) and inserted some data to it. So that my select * looks like
name marksobtained
Mr. Anil 30
Mr. sunil 70
Mr. patel 70
Summed the marks like
select SUM(cast(marksobtained as int)) as 'totalmarksobtained' from sampletab
Which returned 170.
What values does #subjects have? Post some sample.
you can use "cast" in your query
example:
select sum(cast(Enter_your_field_name as int)) from Table_name
Hope it works for you.
I have a large data set and i have to apply paging on that data set and after that the result set should be another data set. What is the reliable method to achieve that.
I have tried with 'PagedDataSource' class but i don't know how it is possible to convert to dataset or data table.
In my case i need a general solution. I have to bind to a control like gridview as well as i have to used it with normal html table.
