Re: Sandwich Query For Employee Attendance using SQL Server 2005

9-Jun-21 12:36

I would do the as 3 queries:

1 get the first absent date date - store it in date1 variable
2 get the next absent date > date 1 - if it exists store it in date2 variable
If date2 is not null (more than 1 day)
3 set all records between date1 and date2 to absent

This covers multi day holidays.

But this will only work on 1 record at a time.

One Employee at a time, correct. So put it in a loop through all employees.

Hi,

I have implemented as per below query,If Employee is absent on Saturday and Monday the weeklyoff should be counted as Absent. I have passed the process date parameter in place of static date.

SELECT A.EmpCode,A.AttDate As Sundate FROM Attendance_Details A INNER JOIN (SELECT A.Empcode,A.AttDate As SatDate,A.AttStatus As SatStatus
FROM Attendance_Details A INNER JOIN (SELECT EmpCode,AttDate As MonDate,AttStatus As MonStatus FROM Attendance_Details
WHERE AttDate='2021-06-07' AND DATENAME(WEEKDAY, '2021-06-07') = 'Monday' and AttStatus IN ('A','HL'))T ON T.EmpCode=A.EmpCode
WHERE DATENAME(WEEKDAY, DATEADD(day,-2,'2021-06-07')) = 'Saturday' AND AttStatus IN ('A') AND AttDate=DATEADD(day,-2,'2021-06-07'))T1
ON A.EmpCode=T1.EmpCode AND DATENAME(WEEKDAY, DATEADD(day,-1,'2021-06-07')) = 'Sunday' AND AttStatus NOT IN('AL','SL','PL','ML','FL') AND AttDate=DATEADD(day,-1,'2021-06-07')

Please help to improve the above query...

Thanks & Regards
Mohammad Salmani

Load JSON file from network location

Hello,
I am trying to load a json file from network location into a table on sql server 2016. The domain account has access to both the file on network as well as the database.
I keep receiving this message:

Cannot bulk load because the file "\\<networklocation>\loaddata.json" could not be opened. Operating system error code 5(Access is denied.).

In the above error message, does the user not have access to file or to perform the "bulk load" action?

Much appreciated!

Also, I am using Windows authentication for SQL server, and this same user also has access to the share on network.

SQL Server 2010, smalldatetime insert

I think it means that the SQL Server identity (not the user) does not have access to the network drive. I always move the file to the SQL Server server or loaded it via c#.

Loading via c# I would put into a datatable EXACTLY matching the destination table and use BULKCOPY [^] to insert it into the destination

I'll swear I have this right
The field is smalldatetime. I'm just picking up the record and inserting it.

On select, I used

CONVERT(varchar(33), ADD_DATE, 121) AS ADD_DATE,

Oninsert, the sql looks like this

'1900-01-01 00:00:00.000'

I read up on sql date times and the different formats. If I pick it raw, and try o insert it, I get an object error.
In SQL Manager, I get

Conversion failed when converting character string to smalldatetime data type.

That is why you used parameterized queries instead of strings.

I guess the VALUES list does not correspond the fields list, so the value form ADD_DATE seems to be '0' rather than '1900-01-01 00:00:00.000'.

I thought about what you both said, and would like to say thanks and show gratitude as well.

I went back and keep the Select statement raw, took the convert out.
The dumped my CRUD function to add the record, and converted the calling function to SQL.
Then used PHP to convert the raw date object I picked up to a string, and declared it in SQL.

I suppose I could go back to my add CRUD function and do the conversion there instead

$result2 = sqlsrv_query($conn, $query2) or die(" setDbProjectCost " . LINE . " - " . $query2 . " - " . print_r(sqlsrv_errors()));
if (sqlsrv_has_rows($result2)) {
    $row2 = sqlsrv_fetch_array($result2);
    $addDateString = $row2[13]->format('Y-m-d H:i:s') . '.000';

    $query3 = "
    DECLARE @addDate AS VARCHAR(33) = '$addDateString';
    INSERT INTO [proj_cost] 
    VALUES ... @addDate

Get columns name

_Flaviu27-May-21 23:55

27-May-21 23:55

If I run a SQL statement, like this:

SQL

SELECT * FROM my_table

is there any SQL statement / trick to find the name of every column from '*' ?

Because if I write:

SQL

SELECT id, name, age FROM my_table

yes, I could extract the columns name, by text analyze. But how about '*' case ?

Yes, I know that, but the question is, how can I know the columns name for the following SELECT (programmatically):

SQL

SELECT * FROM table1, table 2 WHERE table1.id = table2.id;

I'd just do it the same way as for a single table:
- obtain column names for table1;
- obtain column names for table2;
- ...

_Flaviu3-Jun-21 20:37

So, you are saying that I need to do a static analyze on SELECT text and see what columns I have, if I enumerate the columns in the SELECT statement, then I have it, if I don't (I have '*') then I have to query the tables names / columns name and will find them. I thought there is a SQL trick to find the columns name in any circumstances.

Victor Nijegorodov3-Jun-21 21:48

3-Jun-21 21:48

I'd implement such a "trick" in a stored procedure that gets a query as an argument, then creates the temporary View, uses

SQL

SELECT [TABLE_NAME]
      ,[COLUMN_NAME]
  FROM [INFORMATION_SCHEMA].[COLUMNS]
  where TABLE_NAME = <your_temp_view>

to return the recordset with the tables/columns names,
then delete the temp view.

PS: this should work with SQL Server 2008 and above.

Sound good ! Because this solution should be cross server platform, it is available on the other SQL servers, like Oracle, Informix, MySQL, and so on ?
