Create List of Tables/Columns/Data Types
I am new to Oracle (from SQL Server) and I am looking for a query that will create a list of tables, columns, data types, etc. (data dictionary) in an Oracle database -- one that I can import into, say, MS Access or use Crystal reports and create a report that shows the same.
I had a query to do this in SQL Server -- but it was specific to SQL Server. Does anyone have one to do the same in Oracle? I'm hoping not to have to re-invent the wheel.
Thanks!
Hi user653145!
The Data Dictionary has many queries to view informations. Some of these view are
dba_tables
dba_tab_columns
dba_views
etc.
Look for the "Oracle Database Referenc" in the Oracle Onlinedocumentation at
http://tahiti.oracle.com
to get a full list of all data dictionary views.
hope this helps!

Dear All,
We have one user contains more than 100 tables(Production). I need to change some of table columns data types without affect data's.
Please suggest me to do that.
Thanks in advance,
Moorthy.GSDear Sybrand,
Thanks for your reply.
I tried below ways to modify the datatypes.
1) Tried to modify datatype FLOAT to NUMBER while data is persists.
2) Tried to take a export of that user and import the dump without data's and modify the datatype. After that, i tried to import the dump with rows=y option. But it failed due to constraint problems.
Please advise...
Cheers,

Hi, i am using Sybase IQ 16.0
I have created a table, when I want to change one of the data type for a column for example from char to varchar, the list box is grey color and not allow me to change.
Right click table > Properties > Columns > Data Type
I have granted all permission for dba, but still not able to edit. (please see the attached file)
Any help?
Thanks.Hi Nelson.
You can not change the datatype of an existing column.
The doc reference is here: Altering Tables
"After you create a column, you cannot modify the column data type. To change a data type, drop the column and recreate it with the correct data type."
If you already have data in the column, you can try this:
create the new column with a slightly different name
copy the data in to the new column
drop the original column
rename the new column to the old column's name.

Can we create global internal table in data dictionary
help me
i want to know whether we can create global internal tables in data dictionaryHi Swathi,
The whole concept of internal table is to manipulate the data at runtime.
This replaces the concept of two dimentional array in other languages.
The power of internal tables is it gets lakhs of records at runtime. I mean it can accomodate lots of records at runtime.
So you can create a table type in DDIC and use it to declare your internal table.
Yes, You can create global internal tables for function modules.
By declaring the internal table in top include you can use this internal table all the function modules of that function group. So if one function module is filling the data another can use it as it is stored globally.
Hope this answers your curiosity.
Award points if useful else getback.

4.0 EA1 - Data Modeler does not show columns data types correctly
Data Modeler shows all columns data types as 'unknown'.
Hi,
you need to check "system data types" directory and it contents. Its default location in SQL Developer is sqldeveloper\sqldeveloper\extensions\oracle.datamodeler\types
Check "Preferences>Data Modeler>Default system data types directory" setting. If it's empty then copy defaultdomains.xml from previous installation to directory above.
If it's not empty then you need to copy types.xml and defaultRDBMSSites.xml from default location to directory set as "Default system data types directory".

Dear Team,
Japanese characters alone are not passing correctly (passing like ??? or some unreadable characters) to Adobe application when we create input variable as XML data type. The same solution works fine if we change input variable data type to document type. Could you please do needful. Thank youHello,

How to call a stored procedure that has Table Of data types in VB6?
Hi everyone,
I need to call a stored procedure that has a Table Of data type as an input parameter (possibly even several Table Of input parameters). I can't seem to find any example of how to do this in VB6 using ODBC. Is this even possible?
Thanks you!
SteveThanks,
but I need to test stored procedures that uses type defined in the package.
e.g.
if I have s.p.
PROCEDURE get_risultati_squadra
( in_squadra IN VARCHAR2,
out_serie OUT tab_varchar2_5,
out_tiporisultato OUT tab_varchar2_5,
out_n_giornata OUT tab_varchar2_5,
out_squadre OUT tab_varchar2_200,
out_risultato OUT tab_varchar2_10,
out_marcatore OUT tab_varchar2_50,
out_punti OUT tab_varchar2_3,
out_rimbalzista OUT tab_varchar2_50,
out_rimbalzi OUT tab_varchar2_3,
out_esito OUT tab_varchar2_2);
I have to define every type external to the package, in this case five new TYPE !!
Is there another way to solve this problem?

Error when insert data in Sql Server table(DateTime data type)
Hello all,
I have created a database link in oracle 11g to SQL Server 2008 using Sqlserver gateway for oracle,Oracle run on Linux and SQL Server run on Windows platform.
I have queried a table and it fetches rows from the target table.
I am using this syntax for insert a row in Sql Server table.
Insert into Prod@sqlserver (NUMITEMCODE, NUMPREOPENSTOCK, NUMQNTY, NUMNEWOPENSTOCK, DATPRODDATE , TXTCOMPANYCODE, "bolstatus", NUMRESQNTY )
Values (1118 , 1390.0 , 100.0 ,1490 , '2012-06-23 12:37:58.000','SFP' ,0 , 0 );
but it give me error on DATPRODDATE,The data type of DATPRODDATE column in Sql Server is DATETIME.
My Question is how can i pass the date values in INSERT statement for Sql Server DateTime data type.
RegardsJust as with Oracle, you have to specify the date using the to_date() function or use the native date format for the target database (if you can figure out what that is). This is good practice anyway and a good habit to get into.

Database adapter not importing table having data type as WF_EVENT_T
Hi All,
I have a requirement to import a table in the Database adapter. That table is having a column of data type “WF_EVENT_T”.
When I tried to import the table in database adapter I got the error as "The following tables are not supported in the Database Adapter and were not imported".
Then I modified the table by adding one more column with some other data type and tried to import that table.
It got imported successfully but I was not able to see the column with data type WF_EVENT_T in the table.
Any pointers to this would be of great help.
Thanks.Hi Harish
Thanks for your response.
I can create the table with the data type 'String'. However, the problem is when I try to update the table from a program in SE38 or a Function Module in SE37.
When I try to activate the PROGRAM or FUCNTION, I GET A MESSAGE THAT I MENTIONED EARLIER.
Here is the simple program that I have created that I am not able to activate
==========================================
REPORT ZTEST_STRING1.
tables: ztest.
ztest-zid = 2.
ztest-zstring1 = 'ABC'.
insert ztest.
===========================================
ztest has two fields
zid which is NUMC type
and zstring1 which is STRING type.
When I try to activate I get an error message as follows:
'ztest' must be a flat structure. You cannot use internal tables,
strings, references, or structures as components.

Target Site Column Data Type are Undefined Status
Hi,
When I created the mapping,there was a error about data type. Data types of columns were not changed, and datatypes status are undefined.
I take this error as below;
com.sunopsis.tools.core.exception.SnpsSimpleMessageException: The source datatype is null for the column: <ColumnName>, and the technology: Hyperion Planinng
ODI 10.1.3.5
SQL Server 2005
Hyperion Planning 11
How can I changed the datatypes? Is there a problem with hyperion planning site? How can assign the data types?
thanks.First of all the error you posted
"The source datatype is null for the column: <ColumnName>, and the technology: Hyperion Planinng"
Which points to Hyperion planning....
Anyway, if as you say it is file to SQL Server, check the DataStore for the reversed SQL server table, check the columns have a Type assigned to them
Cheers

Problem while creating with QUAN and CURR data type fields
I am trying to create a Z table. A couple of fields are of data type QUAN and CURR, which need to have reference table and reference field.
Field DataType Length Decimal
TOT_QTY QUAN 15 3
PRICE CURR 16 2
For reference table and fields, I found a Table HRPAD23 which has a field called N_QUANTITY (15,3) that matches my TOT_QTY field's data type and it also has a field called UN_PRICE that matches my PRICE field's data type. But when I use them as reference, and try to activate the table, I get an error "combination reference table/field does not exist". How do I fix this? Can anybody help me? Thanks in advance.
Chris
Edited by: martin99 on Aug 18, 2011 9:16 PMMartin,
I doubt that you need to add 2 extra fields in your table as suggested in the last post by John.
Your error is very CLEAR that you seem to be use wrong combination of reference table and field.
For QTY field,
use ref table - HRPAD23. ref field- UNIT
OR
ref table - VBAP ref field - VRKME
For PRICE field,
use ref table - PAD25 ref field - KWAER
OR
ref table - T77REFDOC ref field - CURRENCY
It should work.
