I am totally newbie to Access, I used to use Excel to handle my needs for a while.
But by now Excel has become too slow to handle such a big set of data, so I decided to migrate to Access.
Here is my problem
My columns are:
Number | Link | Name | Status
1899 | htto://example.com/code1 | code1 | Done
2 | htto://example.com/code23455 | code23455 | Done
3 | htto://example.com/code2343 | code2343 | Done
13500 | htto://example.com/code234cv | code234cv | Deleted
220 | htto://example.com/code234cv | code234cv | Null
400 | htto://example.com/code234cv | code234cv | Null
So I want a way to update Status of my rows according to numbers list.
For example I want to update Status column for multiple numbers to become Done
Simply I want to update "Null status" to become "Done" according to this number list
13544
17
13546
12
13548
13549
16000
13551
13552
13553
13554
13555
12500
13557
13558
13559
13560
30
13562
13563
Something like this
I tried "update query" but I don't know how to use criteria to solve this problem
In Excel I did that by "conditional formatting duplicates" -with my number list which I wanted to update-
Then "sort by highlighted color" then "fill copy" the status with the value
I know that Access is different but I hope that there is a way to do this task as Excel did.
Thanks in advance
From my understanding, You can try
Update TblA
Set TblA.Status="Done"
where Number in (13544,17,13546,....)
Or alternatively easy method is to pull these numbers in IN clause into its own table and use it like this
Update TblA
Set TblA.Status="Done" where Number in (select NumCol from NumTable )

After searching TDengine online documentation: https://www.taosdata.com/en/documentation/, I found the the command to change the default database parameter "keep", which indicates how long data will be preserved in databases. However after I have typed in that command from shell, "show variables" command still shows the old value. How would I know if changing this parameter is taking effect?
taos> alter database test keep 50;
Query OK, 0 of 0 row(s) in database (0.019087s)
taos> show variables;
name | value |

keep | 3650 |
the alter command is effective at the DataBase level, and show varibles is show the global parameters.
you can use show databases; to check the database's parameter.
if you want change the show variables;'s show, you should modify the config file /etc/taos.cfg
and there are only serval parameters can modify by alter command.
First off I am have a constraint the my solution must work from SQL Server 2008 R2
The problem that I'm trying to solve is that Excel converts the text value '002E9' to 2.00E+09. The task is to pass the original value '002E9' as text into a CSV file.
I have been passed a SSIS solution by a developer that has a the conversion as a SQL function. They have used
SELECT FORMAT(CAST(2.00E+09 AS FLOAT),'0E0');
This is fine in 2012 and above but does not work in SQL Server 2008 R2.
Is there a simple alternative? I'm happy to abandon SQL for a SSIS script if that's the best advice.
FORMAT doesn't exist in SQL Server 2008; but it's use is best avoided any way; it's an awfully slow function.
You can use CONVERT and the style 0 though:
SELECT REPLACE(CONVERT(varchar(10),CAST(2.00E+09 AS float),0),'+','');
This won't, however, give exactly the same format, and would return '2e009'. Based on the fact that you use the value '0E0' for the FORMAT function though (which would return '2E9' for your example value), I assume this is permissible.
Based upon the post Larnu made I arrived at this (note the REPLICATE function for getting the correct format from the stripped down string):
DECLARE #INPUTS AS table
(input_val varchar(100))
INSERT INTO #INPUTS
VALUES
('00923'),('00234'),('00568'),('00123'),('2.00E+09' ),('2.00E+34' ),('00RT1'),('001TL')
SELECT input_val
,REPLACE(REPLACE(REPLACE(input_val,'+',''),'0',''),'.','') paired_value
,REPLICATE('0',5-LEN(REPLACE(REPLACE(REPLACE(input_val,'+',''),'0',''),'.','')))
+REPLACE(REPLACE(REPLACE(input_val,'+',''),'0',''),'.','')+';' Converted_value
FROM #INPUTS
The results:
+-----------+--------------+-----------------+
| input_val | paired_value | Converted_value |
+-----------+--------------+-----------------+
| 00923 | 923 | 00923; |
| 00234 | 234 | 00234; |
| 00568 | 568 | 00568; |
| 00123 | 123 | 00123; |
| 2.00E+09 | 2E9 | 002E9; |
| 2.00E+34 | 2E34 | 02E34; |
| 00RT1 | RT1 | 00RT1; |
| 001TL | 1TL | 001TL; |
+-----------+--------------+-----------------+
Confirms the approach.
Thanks Larnu.
I have an SSRS report that was pointed to SQL Server views, which pointed to Oracle tables. I edited the SSRS report Dataset so as to query directly from the Oracle db. It seems like a very simple change until I got this error message:
System.InvalidCastException: Specified cast is not valid.
With the following details...
Field ‘UOM_QTY’ and it also says at
Oracle.ManagedDataAccess.Client.OracleDataReader.GetDecimal(Int32 i).
The SELECT statement on that field is pretty simple:
, (DELV_RECEIPT.INV_LBS/ITEM_UOM_XREF.CONV_TO_LBS) AS UOM_QTY
Does anyone know what would cause the message, and how to resolve the error? My objective is use to use the ORACLE datasource instead of SQL SERVER.

The error went away after adding a datatype conversion statement to the data selection.
, CAST(DELV_RECEIPT.INV_LBS/ITEM_UOM_XREF.CONV_TO_LBS AS NUMERIC(9,4)) AS UOM_QTY
Can anyone provide some information on why the original query would be a problem and why the CAST would fix these errors? I tried casting the results because someone on Code Project forum said...
why don't you use typed datasets? you get such head aches just because
of not coding in a type-safe manner. you have a dataset designer in
the IDE which makes the life better, safer, easier and you don't use
it. I really can't understand.
Here is an approach to fix this error with an extension method instead of modifying the SQL-Query.
public static Decimal MyGetDecimal(this OracleDataReader reader, int i)
{
try
{
return reader.GetDecimal(i);
}
catch (System.InvalidCastException)
{
Oracle.ManagedDataAccess.Types.OracleDecimal hlp = reader.GetOracleDecimal(i);
Oracle.ManagedDataAccess.Types.OracleDecimal hlp2 = Oracle.ManagedDataAccess.Types.OracleDecimal.SetPrecision(hlp, 27);
return hlp2.Value;
}
}
Thank you for this but what happens if your query looks like:
SELECT x.* from x
and .GetDecimal appears nowhere?
Any suggestions in that case? I have created a function in ORACLE itself that rounds all values in a result set to avoid this for basic select statements but this seems wrong for loading updateable datasets...
Obviously this is an old-school approach to getting data.
I have an XML column in SQL Server 2005 with the following simplified XML.
+----------+------------------+
| RecordID | ValueXML |
+----------+------------------+
| 1 | <value>x</value> |
| | |
+----------+------------------+
If I want to change that value to y, I use the following SQL statement.
update ValueTable
set ValueXML.modify('
replace value of (/value/text())[1]
with ("y")')
where RecordID = 1
That works fine. x becomes y. The problem happens if value is set to nothing.
update ValueTable
set ValueXML.modify('
replace value of (/value/text())[1]
with ("")')
where RecordID = 1
Once this happens, the table looks like this.
+----------+------------------+
| RecordID | ValueXML |
+----------+------------------+
| 1 | <value /> |
| | |
+----------+------------------+
Now, I can no longer set the value. The replace value query executes successfully, but makes no change.
How can I set the text for a closed XML element? Is it possible to "unclose" the element?
You can't insert a value like that because you are trying to replace the text but there is no text to replace, so it will execute but it will not work.
This seems to be the same problem you're having here.
Thanks #BoogaWooga for pointing me in the right direction. I was able to do my replace in two statements.
First, I ensured the element was closed. This statement works whether the element is closed or not.
update ValueTable
set ValueXML.modify('
replace value of (/value/text())[1]
with ("")')
where RecordID = 1
Now that I know the element is closed, I use insert text to insert a value into the closed element.
update ValueTable
set ValueXML.modify('
insert text{"x"}
into (/value[1])')
where RecordID = 1

I'd like to execute the stored procedures with DbSlim using Fitnesse (Selenium, Xebium)
now what I tried to do is:
!define dbQuerySelectCustomerbalance (
execute dbo.uspLogError
)
| script | Db Slim Select Query | !-${dbQuerySelectCustomerbalance}-! |
which gives a green indicator,
however Microsoft SQL Server profiler gives no actions/logging...
so what i'd like to know is: is it possible to use dbslim for executing stored procedures,
if yes
what is the correct way to do it?
By the way, the connection to the Database i've on 1 page, and on the query page i included the connection to the database. (is that ok?)
Take out the !- ... -!. It is used to escape wikified words. But in this case you want it to be translated to the actual query.
!define dbQuerySelectCustomerbalance ( execute dbo.uspLogError )
| script | Db Slim Select Query | ${dbQuerySelectCustomerbalance} |
| show | data by column index | 1 | and row index | 1 |
You can add in the last line which outputing the first column of the first row for testing purpose if your SP is returning some result (or you can create one simple SP just to test this out)
Specifying the connection anywhere before this block will be fine, be it on the same page or in an SetUp/SuiteSetUp/normal page included/executed before.
