How to handle 0E-8 in Hive query - sql

I am running an Sql query and extracting the result in Excel.In Excel, particular column was showing as Exponential format(0E-8).Column datatype has Decimal(31,8).
I have tried below:
cast(column as double)
Result was showing as 0[If column has 0.00000000].
If my Excel need to be show like 0.00000000[Exact same has DB has],how we can handle in query.

Need to get a value till precision of 15 digit after decimal in DB2 Query

One of DB2 table column value is appearing as 0.3901369869709015 and we need to compare this value against my expected value as 0.390136986970901. I tried to get the value from DB2 by using Decimal/Dec method. With that the value is getting round off and appearing as 0.390136986970902. Could you please help me to correct the below query that i am using to extract data from my DB2 table.
SELECT DECIMAL(UV_FIELDSCOREMAP,15,15) AS UV_FIELDSCOREMAP From cvsinst.uv_occ WHERE CASEID = '20170720'
Use TRUNCATE(UV_FIELDSCOREMAP, 15) instead.

Excel connected dbf database with null/empty, SQL query not working

An old dbf have been succesfully ODBC-connected to Excel (2010). The following SQL query (through Microsoft Query) works as expected giving a single result.
Microsoft Query (Excel 2010) code
SELECT c.NDELNUM AS deliverynote, SUM(c.NQTY*a.CPREDEF2) AS Total
FROM DelCusL AS c, Article AS a
WHERE c.CREF = a.CREF AND ((c.NDELNUM=?))
GROUP BY c.NDELNUM
I am interested in getting also single value, but the following retuns NULL:
SELECT c.NDELNUM AS deliverynote, SUM(c.NQTY*(a.CPREDEF2+c.CPROP2)) AS Total
FROM DelCusL AS c, Article AS a
WHERE c.CREF = a.CREF AND ((c.NDELNUM=?))
GROUP BY c.NDELNUM
I guess this does not work because empty values are encountered in either a.CPREDEF2 or c.CPROP2. When an empty value is encounterd, I'd like it to be treated as 0. I have tried casting value functions available in Microsoft Query to not much avail.
Any idea on converting EMPTY values to 0s so that the operation is successful?
NQTY is a number and always non-empty. CPREDEF2 is treated as VARCHAR and can be EMPTY: when EMPTY it seems to be treated as NULL from other tests; CPROP2 is an alternative value to CPREDEF2 and can also be EMPTY, if filled it can be understood as number(like CPREDEF2). Both CPREDEF and CPROP2 are treated as VARCHAR rather than numerical values but when on their own are correctly multiplied and aggregated as numbers. (It fails when I try to add them together before the aggregate function).
Try to CAST before you add the values:
... * (CAST(a.CPREDEF2 AS DECIMAL(10,5))+CAST(c.CPROP2 AS DECIMAL(10,5))) ...

Access SQL Date Function

So I'm working on editing some SQL code and I've just began learning it. I'm trying to fix an update query so it updates a table's value5 column with a corresponding database value. The value type from the database is a number, which I want to convert to a date and place into my table. The database number is in yyyymmdd format so I've been trying to use datefromparts() which doesn't work. Anyone have any ideas?
UPDATE tbl INNER JOIN dB ON
(dB.value1= tbl.value1 OR
dB.value2 =tbl.value2 ) AND
(LEFT(dB.value3 ,5)=tbl.value3 ) AND
(dB.value4 =tbl.value4 )
SET tbl.value5 = DateFromParts(Left(dB.value5,4),Mid(dB.value5,5,2),Right(dB.value5,2))
WHERE tblInvoice.value5 IS NULL;
The current program uses the code
"SET tbl.value5 = dB.value5"
instead (it runs perfectly fine) and I am having another issue with testing the conversion SQL code (datefromparts()). Because I am converting from numbers to time/date, I have to go into the design view of the target table and change the input data type of the value5 column from numbers to time/date. When I run the query with the conversion SQL code, the query stalls for a bit and no values get updated, leaving me with just a blank value5 column. If I now want to fill in the original number values, I change the SQL code back into its original "SET tbl.value5 = dB.value5", change the input data type from time/date to numbers, and rerun the program. The query stalls and no values are updated, and I am again left with blank columns, even though the same code left me with the corrected update values before the modifications to the SQL and table input Data types. I come from a VBA background and I'm just really confused with how this is working. Any tips would be appreciated, thanks!
Have you tried with substring instead?
SELECT DATEFROMPARTS ( left('20101231',4), substring('20101231',5,2), right('20101231',2) ) AS Result;
MS Access (and MS Jet too) have no DateFromParts function. Using DateSerial instead.
SET tbl.value5 = DateSerial(Left(dB.value5, 4), Mid(dB.value5, 5, 2), Right(dB.value5, 2))
It's not clear if you work with T-SQL or Access SQL. In Access, you can use Format:
SET tbl.value5 = CDate(Format(dB.value5, "####\/##\/##"))
In T-SQL you could use a similar method.

PowerQuery - Using a cell in a table as part of the code in a query (dynamically or not)

I am trying to use a cell as a parameter in Excel powerquery. The query works without this, but I have to manually input the values, which I need to constantly change them in the query in other to get the results that I want.
Query (Advanced Editor):
let
Criteria01 = Excel.CurrentWorkbook(){[Name="Servers"]}[Content][ServerSearch]{0},
Criteria02 = Excel.CurrentWorkbook(){[Name="Servers"]}[Content][ServerSearch]{1},
Criteria03 = Excel.CurrentWorkbook(){[Name="Servers"]}[Content][ServerSearch]{2},
Source = Sql.Database("SERVERNAMEHERE", "DATABASENAMEHERE", [Query="SELECT DISTINCT [...........] AND (TABLEPREF.COLUMNHERE like '%MANUALVALUE01%' OR#(lf)TABLEPREF.COLUMNHERE like '%MANUALVALUE02%' OR#(lf)TABLEPREF.COLUMNHERE like '%MANUALVALUE03%' OR#(lf)TABLEPREF.COLUMNHERE like Criteria01)#(lf)#(lf)#(lf)order by 1 asc"])
in
Source
"Servers" is the table name and "ServerSearch" is the column header. If I check the step for Criteria01/etc it will show me the correct value of that table that I need to use.
Original query done in Sql-Server. I have no problems when running the query with only LIKE '%MANUALVALUES%' lines.
My main goal is to automatically get N values of "MANUALVALUES" from a table in a sheet, which will be used as an input for comparing WHERE TABLEPREF.COLUMNHERE like '%VALUEHERE%'. I must use this and I can't get the whole table/database because there are way too many results besides the ones that I want.
However for test purposes at this moment, I am trying to use only 1-3 values, the first 3 of this table (Criteria{0}{1}{2} in the query above). However, if I try to do something like TABLEPREF.COLUMNHERE like Criteria01 I get the following error:
DataSource.Error: Microsoft SQL: Invalid column name 'Criteria01'.
Details:
DataSourceKind=SQL
DataSourcePath=dalsql390;itdw
Message=Invalid column name 'Criteria01'.
Number=207
Class=16
So my questions are:
I am getting the table cell value by the right way? Meaning:
Excel.CurrentWorkbook(){[Name="Servers"]}[Content][ServerSearch]{0}.
How do I refer this value in my query? Since the way that I wrote
that query bought me that error.
Also please note that if change TABLEPREF.COLUMNHERE like
Criteria01 to CHG1.CI_Name like "Criteria01" I get the
following error:
Expression.SyntaxError: Token Comma expected.
After fixed 1 and 2, how can I use this dynamically? For
example, instead of getting values of index 1 2 3, what if I want to
use a whole table? I know that using
Excel.CurrentWorkbook(){[Name="Servers"]}[Content] will bring me the whole table of values (1 column, unknown number of rows), but
how do I use this table content 1 by 1 in my query?
That will get the value, but you can't refer to steps inside of text values by putting the step name inside of it.
You have a couple options for doing this dynamically.
Use Value.NativeQuery to create a parameterized query where you can pass in other values as parameters. For example, Value.NativeQuery(Sql.Database("SERVERNAMEHERE", "DATABASENAMEHERE"), "select #a, #b", [a = 1, b = "x"]) will return the table [1, x]. You can put in the step name in the record value to pass that it (e.g. replace "x" with Criteria01).
Add the text values directly in the query field, e.g. [Query = "select " & Criteria01 ";"]. This is highly discouraged since this can lead to SQL injection issues.
For the third question, it depends what you want to do with the list of values. At some point you will likely need List.Accumulate to turn them all into a single text value which can be placed in the query value, and maybe to turn them into a record to place into the parameters value.

SQL Query returns comma separated data

I am running the below query through MS Query on an ODBC connection:
SELECT oa_cstexpbal_0.costcentre, oa_cstexpbal_0.expensecode, oa_cstexpbal_0.yearno,
oa_cstexpbal_0.baltype, oa_cstexpbal_0.openbal, oa_cstexpbal_0.periodbal
FROM OPENACC.PUB.oa_cstexpbal oa_cstexpbal_0
WHERE (oa_cstexpbal_0.yearno='2016') AND (oa_cstexpbal_0.baltype='AV')
and it returns the below data into one column for periodbal:
406186.06;317084.39;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0
Is there a way I can separate out the periodbal data to stop it coming through as comma separated?
I am connecting to a sql 2008 Db call OPENACC.PUB and using the original query to pull through the data. The only column that is retuning with a ; is the periodbal. when dumped into excel this can be corrected through Text To Columns but ideally I want to try and do this in the query (if possible).
Assuming you use MS SQL Server you want to split data which are separated by semicolon in your column to rows so you handle them in SQL.
If that is correct, then you need to split them. As SQL server can not do this by default you have various way to do so.
See this post http://sqlperformance.com/2012/07/t-sql-queries/split-strings for some general informatione.
Here https://codereview.stackexchange.com/questions/15125/sql-server-split-function-optimized I posted once a split function, that works in SQL, too.
So one approach can be:
SELECT oa_cstexpbal_0.costcentre
, oa_cstexpbal_0.expensecode
, oa_cstexpbal_0.yearno
, oa_cstexpbal_0.baltype
, oa_cstexpbal_0.openbal
, oa_cstexpbal_0.periodbal
, s.value AS periodbal_as_rows
FROM OPENACC.PUB.oa_cstexpbal oa_cstexpbal_0
CROSS APPLY dbo.fn_Split(oa_cstexpbal_0.periodbal,';') AS s
WHERE (oa_cstexpbal_0.yearno='2016') AND (oa_cstexpbal_0.baltype='AV')
