It is a php variable.

NULL/Blank Collation After DB Restore

May 7, 2004

If a database's collation is blank under enterprise manager and NULL with SELECT DATABASEPROPERTYEX('<Database_Name>', 'Collation') does this mean it has the same collation as the server?

The reason I ask is that I restored a database with a different collation to my server and so I expected the different collation name to show up.
Its showing as blank though...
I thought databases kept their original collation even if restored to another server.
(The database was restored as a new database).

Blank Report Shows Up For Null Parameters.

Oct 29, 2007



I have created a report with a stored proc which takes a parameter whose default value is null. Now when I run my stored proc in Enterprise Manager without any params I get 4 rows otherwise with proper parameter I get 2 rows.

Now I set the params value to allow for Null and blank values. When I run the report if I provide parameter value it works fine but if i try to run it without any param it shows an empty report while the stored proc running without params shows 4 rows.

I have earlier sucessfully created reports where stored procs had 4 params out of which 3 where defaulted to null. And so I set the allow nulls, Allow Blanks values to be true for those params in Rep services. So when I selected value for 1st param and ran the report I got the desired report. But this time I have only one param which can be null. But its not working.

Thanks in advance.

Anyway To Check If A Text Field Is Blank (not Null But Just A Empty String '') ?

Oct 27, 2004

i have a trigger on a table right now... when fields are inserted, theres a text field inserted and i want to check if that text field = '' (the empty string, not NULL) and if it doesn't equal that, then perform some row updates on other tables, but if it is empty, to not do anything else in the trigger... right now i have this:


Code:


IF ((SELECT Note FROM XATPoDetail WHERE ReqNbr = (SELECT ReqNbr FROM Inserted)) LIKE(''))



Note is the text field, XATPoDetail is the table where its being inserted into. I had to do the select FROM the table because it wouldn't let me select a text data type from the "Inserted" virtual table

but it tells me me "Error 279: The text, ntext, and image data types are invalid in this subquery or aggregate expression"

thanks

SQL Parameter Update Not Updating Changed Null/blank Values

Oct 24, 2006

I am attempting to update a sql db using the update and parameter code in VB.net 2003 through MSDE for a web application. It updates changed data OK, but if the textbox value is deleted, the code does not update the sql db. I am new to this, and I'm sure it is something simple. Here is some sample code.

SqlConnection1.Open()

strSQLu = "UPDATE table1 " _
& "SET Field1Tag = @Field1Tag, Field2Tag = @Field2Tag " _
& "WHERE (Field1Tag = @Field1Tag) "

cmdCategoriesUpdate.CommandText = strSQLu

With cmdCategoriesUpdate
.Parameters("@Field1Tag").Value = txtFld1.Text
.Parameters("@Field2Tag").Value = txtFld2.Text
End With
cmdCategoriesUpdate.ExecuteNonQuery()
SqlConnection1.Close()

Default To NULL Instead Of Blank/empty String During Flat File Import

Aug 15, 2006

Hi,

In SSIS flat file import using fastload, I'm trying to import data into SQL 2005 previously created tables.

The table may contain column that are NULLable BUT there is NO DEFAULT for them.

If the incoming data from flat files contains nothing either between the delimeters, how can I have a NULL value inserted in the column instead of blank/empty string?

I didn't find an easy flag unless I'm doing something wrong. I know of at least two ways to do it the hard way:

1- set the DEFAULT(NULL) for EVERY column that needs this behaviour

2-set up some Derived Column option in the package to return NULL if the value is missing.

Both of the above are time consuming since I'm dealing with many tables. Is there a quick option to default the value to NULL WHEN there is NO data ELSE insert the data itself? So the same behavior that I have right now except that I want NULL in place of empty string/blank in the varchar(x) columns.



Thanks

Anatole

Integration Services :: SSIS Insert Non Null Value Into Null Rows

Jul 15, 2015

I have a flat file with the following columns

SampleID   Rep_Number   Product  Protein   Fat   Solids

In the flat file SampleID and Product are populated in the first row only, rest of the rows only have values for Rep_Number, Protein, Fat, Solids.

SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.

Bcp/BULK INSERT And Blank Lines

Jul 18, 2006

Does anyone know of a way to make BULK INSERT or bcp ignore blank lines in the file? I am having trouble with a bunch of data files coming back with 1 or 2 blank lines at the end, and it causes the entire bcp to fail.

I suppose I could write a utility to trim the files but that seems a bit overkill. Any thoughts?

I need to pass in null/blank value in the date field or declare the field as string and convert date back to string.

The mfg_start_date is delcared as a string variable

mfg_start_date = CStr(CDate(Mid(rs_get_msp_info(2), 3, 2) & "/" & Mid(rs_get_msp_info(2), 5, 2) & "/" & Mid(rs_get_msp_info(2), 1, 2)))

With refresh_shipping_sched
.ActiveConnection = CurrentProject.Connection
.CommandText = "spRefresh_shipping_sched"
.CommandType = adCmdStoredProc
.Parameters.Append .CreateParameter("ret_val", adInteger, adParamReturnValue)

SQL Server 2008 :: Non Blank / Non Null Value From Table To Update Same Table

Mar 13, 2015

Here is the sample data for table.

create table #sample (emp varchar(max),data1 varchar(max),data2 varchar(max), Rdate date)
insert into #sample (emp,data1,data2,rdate)
values('john','','',getdate())

insert into #sample (emp,data1,data2,rdate)
values('tony','','',getdate())

[Code] ...

I need to update the data1, data2 from yesterday or before but they should be non blank and non null and update to todays data.

It means, I can't update to 2015-03-12 values to 2015-03-13, as they are blanks or nulls.

So I need to go 2015-03-11 and check the values, if they are not blank , i need to update with todays values.

Before the update :

empdata1data2Rdate
john3/13/2015
tony3/13/2015
john3/12/2015
tony3/12/2015
johncd3/11/2015
tonyab3/11/2015

After the update:

empdata1data2Rdate
johncd3/13/2015
tonyab3/13/2015
john3/12/2015
tony3/12/2015
johncd3/11/2015

Insert When Null

May 12, 2008

Dear All,

I am populating some new tables from old tables, after I did some re-structuring to the database.

I have created a table with langID and langCode.

I also created a temptable, with the data being captured from an old table. The fields that are the most relevant at the moment are lid, and fk_langid.

In the old table, lid, has strings in it, for example en, fr, bg etc, and fk_langId will be the foreign key to the new table.

Now my problem is that there are some lid's which do not exist in the new table, and as so I need to hardcode an id for them in the new table.

So I was doing something like this:-

update #tempTable
SET fk_langid =
(
SELECT lid,
CASE
WHEN lid like '%sr%' THEN '1234'
END
FROM #tempTable
)

But I am getting an error:-

Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.

Can you help me out on how I can update the fk_langid in the temptable
