Access Query to Oracle Query conversion

I am converting an Access database to Oracle 8.1.6.
There are lot of reports in Access. HOw can I convert the Access
query to Oracle equivalent query??? Is there any tool available
for conversion???

FYI,
Microsoft Access is using ANSI SQL. And Oracle has introduced ANSI SQL from Oracle 9i so, it is also in 10g.
Oracle 10g does not stop backward compatibilty so, It is depends on person. And I am not forcing you to migrate query from ACCESS to Oracle. I have simply answer the question which you have asked. Whether you want to perform efficiently or not it's your choice.
But one thing is sure, ORACLE (9i or 10g) provides ANSI SQL and MS ACCESS is using ANSI sql so, this task is feasible. No doubt about it.

Help needed in changing Access query to Oracle query

hello folks,
I have already posted this question and got some help previously but i have additional query being added to the previous one so thought of seeking some help.here it goes
Am having an access report which comes from a query. the current query behind the report is a consolidated one and comes from quite a few tables . My requirement is to develop a crystal report( which comes with a native oracle db driver) which should look same as the access report. But am unable to use the access query becoz of its format or something. So anyone please throw some light on this. Any help would be kindly appreciated.
SELECT Debtor . EVENT_ID,
Debtor . MEDCAP#,
Debtor . Client Name,
Debtor . CLIENT,
Debtor . Provider ID,
Debtor . GROUPNUMBER,
"OPEN" AS Status,
(IIf(clip_file = "Y", "Clip", "Open")) AS clipStatus,
IIf(collect_only = "Y", "Collection Only", "Regular Collections") AS Collect ?,
IIf(IsNull(Principal), 0, principal,
IIf(IsNull(PAR_FLAG), "N", IIf(PAR_FLAG <> "N", "P", PAR_FLAG)) AS PAR_NPAR_FLAG,
Right(PatientMemberID, 2) AS Patient Suffix
FROM Period, Debtor
INNER JOIN LOB_subtypes ON Debtor . SUBTYPE = LOB_subtypes . SUBTYPE
WHERE (((Debtor . CLIENT) = "CV1") And ((Period . PeriodName) Is Not Null) And
((Debtor . STATUS) = "OPEN") And ((LOB_subtypes . LOB) = "PBA"));
Thanks

The expression...
IIf(IsNull(Principal), 0, principal) - IIf(IsNull(PRORATED_TRANAMT), 0, prorated_tranamt)...is equivalent to...
NVL(PRINCIPAL, 0) - NVL(PRORATED_TRANAMT, 0)Does that answer your question?
As for...
IIf(IsNull(PAR_FLAG), "N", IIf(PAR_FLAG<>"N", "P", PAR_FLAG))...you might try...
CASE
    WHEN PAR_FLAG IS NULL THEN 'N'
    WHEN PAR_FLAG != 'N' THEN 'P'
    ELSE 'N'
END

MS Access Query to Oracle

Hi Gurus
I am trying to convert a MS Access query to Oracle query, Having some trouble Need some help Please.
This is the MS Access Query:
Sum(IIf(LOAD1!ARRIVDATE<+Date()+7,LOADLINE1!QTY,0)/ITEM1!UOM) AS Loadtbl
What would be the Oracle Query???
Thank you

Hello,
well, the problem is the name of the column, ARRIVDATE< - while MS Access allows the "<" inside a column name, Oracle doesn't if you don't be careful. Please see this:
SQL> create table testtab1 (arrivdate varchar2(100));
Table created.
SQL> desc testtab1
Name Null? Type
ARRIVDATE VARCHAR2(100)
SQL> create table testtab2 (arrivdate< varchar2(100));
create table testtab2 (arrivdate< varchar2(100))
ERROR at line 1:
ORA-00902: invalid datatype
But this works:
SQL> create table testtab2("ARRIVDATE<" varchar2(100));
Table created.
SQL> desc testtab2
Name Null? Type
ARRIVDATE< VARCHAR2(100)
So your query might work if you put ARRIVDATE< in double quotes:
Sum(DECODE(LOAD1."ARRIVDATE<"+SYSDATE+7,LOADLINE1.QTY,0)/ITEM1.UOM) AS Loadtbl
Regards
Wolfgang

Access Query to Oracle View Tool

We have a Access Database which creates forms and reports. It has lots of queries. we want the similar funtionalities in Oracle. Is there any tool that will convert these access queries to Oracle views. I used Migration workbench to convert the database but it can't convert the query.

How to run a MS Access Query from Servlet

Is there a way to execute an MS Access query from a servlet. I have a query that is doing an INSERT into the database. I tried to code the servlet to directly do the query itself, but it keeps locking the database and hanging. I would appreciate any help.
Thanks,

r u refering to the query saved inthe MSACCESS, if so then it may not be possible, bcoz it is not a pure RDBMS. otherwise the u can do it as inthe above mention thread.

Email access query from powershell

I am trying to utilise the DoCmd.SendObject command, from powershell... I have the script launch the required database but I cannot get it to export the query information into Xl format and email it...
This ran the macro that I had produced in Access but I was then required to manually click on an Outlook warning box so it has not resolved the issues.
I just need to get this query data out of access either to save it locally and then send it via email or send it automatically...
Does anyone have any experience of this?
Your help will be most appreciated!
Regards
Richard

Hi Richard,
If you want to export the access query to excel format and send the excel report, have you tried the
DoCmd.OutputTo
Method, please also note I haven't tested
$db = New-Object -ComObject Access.Application
$db.OpenCurrentDatabase("foo.accdb")
$db.DoCmd.OutputTo(1,"The_Report","YourQueryName", "Excel Workbook (*.xlsx)", , True)
Refer to:
Powershell Interaction with Access 2007, how to Save Report as PDF?
DoCmd.OutputTo in xlsx (Excel 2007+) Format
If there is anything else regarding this issue, please feel free to post back.

Help with Converting an Access query

Hello:
First time poster and would appreciate some help in converting this Access query into T-SQL so I can use in a Stored Procedure. I don't need help in resolving the syntax for the variables as parameter in the second query, but stuck in writing the first query
in T-SQL . I assume I need some type of nested query with a left join to another query in T-SQL.
How do I convert this from Access into MS-SQL
SELECT TBL_MONTH.L_Month, TBL_MONTH.L_MonthName
FROM TBL_MONTH LEFT JOIN qry_MonthCheck ON TBL_MONTH.L_Month = qry_MonthCheck.L_Month
WHERE (((qry_MonthCheck.L_Month) Is Null));
qryMonthCheck in Access is defined as
SELECT TBL_MONTH.L_Month, TBL_SIGNOFF.SO_YEAR, TBL_SIGNOFF.SO_USER, TBL_SIGNOFF.SO_LOCATION
FROM TBL_MONTH RIGHT JOIN TBL_SIGNOFF ON TBL_MONTH.L_Month = TBL_SIGNOFF.SO_MONTH
WHERE (((TBL_SIGNOFF.SO_YEAR)=[forms]![frm_signoff]![cboyear]) AND ((TBL_SIGNOFF.SO_LOCATION)=[Tempvars]![tmpVarUserLOC]));

It is very much up to personal taste. For tables I use no prefix at all. Or suffix. I prefer plural: categories, products, etc. For junction tables, I drop the plural in the first entity, for instance productcategories. As for the case, many people prefer
initial uppercase, while I go for lowercase only. But initial uppercase has its points, particularly in documentation. I am a staunch advocate of using case-sensitive collation for metadata. I don't see any point in mixing productcategories, Productcategories,
ProductCategories etc. That can only cause confusion.
As for either entities, I don't use views much, and I don't have any prefix for these either. In fact, several views I've been involved used to be tables once upon a time.
If you want to add a marker to the object name, I recommend using a suffix. It is much easier to find objects in the version control system and other browser, when not everything is cluttered on the same letter. For instance, I typically add _sp at the end
of stored procedure names.

How changing the criterion for an access query in java?

Hi @ all
I would like to change a criterion for an access-query in java. I know how to run a access-query in java. How can I change the criterion in my access query in java without running the query it selfs? Can anybody help me?
Thx

You can't.
The database processes the query and then returns the result to you. Thus to change the query you must run the query again.
You can of course add code do do the same thing. But unless it is very simple it is going to take a lot of code and might even be slower than doing the database call.

Random results with random access query

Hi,
when I execute a random access query
(fetchConfig.setResultSetType(ResultSet.TYPE_SCROLL_INSENSITIVE);
fetchConfig.setFetchDirection(ResultSet.FETCH_UNKNOWN)) and iterate over the
result set twice, the second time the objects are retrieved in a different
order, also when I set the ordering of the objects. This only happens if the
first loop touches the last item. If not, everything works fine. I am using
MS Sql Server, microsoft driver, kodo 3.4
regards,
Christiaan

Hi,
I am using datastore identity. I do implement equals and hashcode in the
super class, not sure whether that is of any impact. The order of the items
look random to me, however it stays constant after the second loop. The same
order is also produced when I re-start the test application. The output
shows the index of the object I am retrieving, the description of the object
(which is also the order in which the items are created) and their order
attribute. The query sorts on the order attribute. As you can see the first
loop is correct. I now and then have the situation where the last item in
the first loop (retrieve 7) results in the first item (item nr 0) being
retrieved. Same behaviour applies for both jtds and microsoft driver.
first loop:
retrieve 0: item nr: 0 order: 0
retrieve 1: item nr: 1 order: 1
retrieve 2: item nr: 2 order: 2
retrieve 3: item nr: 3 order: 3
retrieve 4: item nr: 4 order: 4
retrieve 5: item nr: 5 order: 5
retrieve 6: item nr: 6 order: 6
retrieve 7: item nr: 7 order: 7
second loop
retrieve 0: item nr: 3 order: 3
retrieve 1: item nr: 6 order: 6
retrieve 2: item nr: 7 order: 7
retrieve 3: item nr: 0 order: 0
retrieve 4: item nr: 5 order: 5
retrieve 5: item nr: 4 order: 4
retrieve 6: item nr: 2 order: 2
retrieve 7: item nr: 1 order: 1
third loop
retrieve 0: item nr: 3 order: 3
retrieve 1: item nr: 6 order: 6
retrieve 2: item nr: 7 order: 7
retrieve 3: item nr: 0 order: 0
retrieve 4: item nr: 5 order: 5
retrieve 5: item nr: 4 order: 4
retrieve 6: item nr: 2 order: 2
retrieve 7: item nr: 1 order: 1

Christiaan-
My first guess is are you using application identity, and if so, are you
correctly implementing the equals() and hashCode() method? Failure to do
so may conceivably cause this problem.
Otherwise, can you provide some details about how the results are our of
order? It it exactly reverse or something, or are elements in random
order?

SSMS Addin - How To Access Query Results Grid

Hi,
I want to access Query Result Grid(Results) in SSMS addin but I did'nt found anything.
How can I access Query Result Grid, Rows, Columns and Cells when I executed a script?
Thanks.

SQL Server Management Studio currently supports query execution results to be displayed in three different ways: Results to Grid,
Results to Text and Results to File.
By default SQL Server Management Studio is configured to display query results in
Grid format. If you want to change the default to some other option follow these steps.
1. In SQL Server Management Studio, under Tools menu, click
Options as shown in the snippet below.
2. In the Options dialog box, expand Query Results, expand
SQL Server and then select General as shown in the snippet below. In the right side panel choose one of the three options shown below in the
Default Destination for results drop down list and click
OK to save the changes as shown in the snippet below. The changes will go into effect once you open a New Query window.
Query Result Options for Results to Text
In this format you have the option to display the results in a different tab as well as setting different output options.
In the Options dialog box, expand Query Results, expand
SQL Server and then select Results to Text tab as shown in the snippet below. In the right side panel first select the checkbox for
Display results in a separate tab and then select the checkbox for
Switch to results tab after the query executes and then click
OK. If you would like to also display the column name in the result set then choose the option Include column headers in the result set
as shown in the snippet below.
The options you can use in the Text format are:
Output format: - In the above snippet you could see that by default the output is displayed as columns aligned. Some of the other options that are available are Comma Delimited,
Tab Delimited, Space Delimited and Custom Delimited. If you choose the Custom Delimited option in the Output format drop down list then you need to specify a character of your choice for the delimiter in the
Custom delimiter text box.
Include column headers when copying or saving the results: - If this option is selected, then whenever the results are copied to clipboard or it is saved to a file the column headers are also copied along with the results.
Include the query in the result set: - The text of the query is displayed as part of query output under the messages tab.
Scroll as results are received: - If this option is selected, then the display focuses on the most recently returned records at the end of the results set.
Right align numeric values: - If this option is selected, then numeric values will be aligned to the right of the column.
Discard results after query executes: - If this option is selected, then the query results are not displayed in the reviewing pane.
Display results in a separate tab: - If this option is selected, then the result set after query execution will be displayed in a new tab instead of at the bottom of the query window.
Switch to results tab after the query executes: - If this option is selected, then after the query execution the screen focus will be set to the results tab.
Maximum number of characters displayed in each column: - This sets the maximum characters to display for any one column. So if you have a column that is 500 characters this will only show the first 256 if you keep the default setting.

MS Access Crosstab to Oracle SQL

Gurus,
I am trying to convert MS Access Query to Oracle SQL, What would be the Oracle query for this MS Access Crosstab Query?
I am working on Oracle 10g so, I can't take advantage of oracle PIVOT function.
Thank you

if your crosstab columns are static you can use well-known technique like
select tablespace_name,
sum(case segment_type when 'TABLE' then bytes end) TABLES_BYTES,
sum(case segment_type when 'INDEX' then bytes end) INDEXES_BYTES,
sum(case segment_type when 'LOBSEGMENT' then bytes end) LOB_BYTES
from dba_segments
group by tablespace_name;
for dynamic crosstab columns you require to build this query dynamically in application

How to connect access database through oracle sql prompt

i want to connect access database via oracle , i am trying to import all the data in Access table into oracle table how it is possible .
A.R

The simplest way, if You have already created tables in Oracle DB, is to open the Access MDB, link Oracle tables via ODBC and build a query to append rows reading from Access tables to Oracle tables.
Hope this helps

Convert IIF Access SQL to Oracle SQL...

Hi, Simon,
Welcome to the forum!
An Oracle equivalent of
IIf(TEMP_ACTION_DISCIPLINE Is Null,"UNALOCATED",TEMP_ACTION_DISCIPLINE) AS ACTION_DISCIPLINEis
CASE
     WHEN TEMP_ACTION_DISCIPLINE Is Null
     THEN 'UNALOCATED'
     ELSE TEMP_ACTION_DISCIPLINE
END          AS ACTION_DISCIPLINE, This assumes that temp_action_discipline is a string. (All THEN and ELSE clauses must return the same data type, or at least compatable types.)
CASE is the most general way of doing IF-THE-ELSE logic in Oracle SQL.
For certain special situations, there may be shorter ways.
Testing a variable to see whether it is NULL or not is one of those situations, so you could also say
NVL2 ( TEMP_ACTION_DISCIPLINE
     , TEMP_ACTION_DISCIPLINE
     , 'UNALOCATED'
This site noramally compresses whitespace. Whenever you post formatted text here (and code should always be formatted), type these 6 characters:
(all small letters, inside curly brackets) before and after formatted sections.
Edited by: Frank Kulash on Jan 21, 2010 10:41 AM
After reading Bluefrog's answer, I realized that you're testing and possibly returning the same thing, temp_action_discipline.
In that case, NVL, like Bluefrog suggested, is the best thing to do. CASE and NVL2, as shown above, will give the right results, but they're more complicated than you need for this job.

Access to linux oracle migration

Hi. I have a huge access application and database that I am
trying to migrate from access to the linux version of oracle 8.
I have the access application and database in seperate mdb files.
Is there a way I can convert this db to oracle 8 for linux and
preserve all the rules in my database. Also what will happen to
any of my queries that use directsql. Thank you very much.

hi Birju,
You can download the MS Access conversion kit from this web site
and this will migrate application and database to Oracle on any
supported platform (including Linux).
Log onto http://technet.oracle.com
Go to Technologies
Go to Migration technologies
Go to Migration Toolkits
and pick the MS Access kit for Oracle 8.1.5
We hope to have a plugin that will allow users to migrate from
Access to Oracle8i (on any supported platform) in the very near
future. This plugin will work with the Oracle Migration
Workbench.
