DATE in TIMESTAMP data type conversion
HelloMy question is this:
1. I have a variable of type DATE, which I attribute the value of SYSDATE
mydatevar DATE:= SYSDATE;
2. I want to find * «today» *, truncated to DATE
TRUNC (mydatevar, 'DD')
TRUNC function returns the DATE data type. So I get to the point for example 2 *'2010-01-13 00:00:00 ' *.3. I want to assign the value of the point 2, to a variable of type TIMESTAMP
mytimestampvar TIMESTAMP := mydatevar;
implicitly that will convert the variable DATE to TIMESTAMP.Problem: when converting (implicit and explicit conversion with a format mask), I lose hours "00" and "00" minutes and receive something like this: "10 January 13 * 12 *. 00.00.000000000 AM.
Question: How can I convert a DATE to TIMESTAMP keeping the hours and minutes zeros?
Why I need this conversion: I have a table with one "column1" TIMESTAMP column (0) and I take only the rows of the table, where 'column1' is in the range of today 12:00 in the morning until now (what time it is).

I don't think you lose necessarily any information whatsoever. It is probably more a function of your NLS_TIMESTAMP_FORMAT and NLS_DATE_FORMAT. For example, your NLS_DATE_FORMAT could be default setup for a HH24 (24 hours) which would report to midnight as hours of "00". However, it seems that your NLS_TIMESTAMP_FORMAT is configured with "HH" format with a Meridian indicator that means 12 hours time.
Your comparisons should use date/timestamp data types anyway, so as long as the input value is correctly converted to date type that shouldn't matter in any case.
You can see what is actually stored by using the DUMP function:
SQL> SELECT DUMP(TO_TIMESTAMP(TO_CHAR(TRUNC(SYSDATE,'DD'),'MM/DD/YYYY HH:MI:SS AM'))) AS TSTAMP
2 , DUMP(TRUNC(SYSDATE,'DD')) AS DT
3 FROM DUAL
4 /
TSTAMP DT
--------------------------------------------------------------------------- --------------------------------------------------
Typ=187 Len=20: 218,7,1,13,0,0,0,0,0,0,0,0,0,0,3,0,0,0,0,0 Typ=13 Len=8: 218,7,1,13,0,0,0,0
As you can see the TSTAMP and DT store almost the same values (218,7,1,13), but the TSTAMP has more precision because of fractions of a second.
HTH!

Create another data base of Liquibase changelog: automatic data type conversion
I need to convert the structure of PostgreSQL databases to Oracle. In PostgreSQL, I a postgres database.
In Oracle, I have an empty database in which I want to write to postgres database in PostgreSQL.
Actually, I didn't need the data, only the structure (relationships).
For this, I use Liquibase. I get the changelog of PostgreSQL with the command:
Liquibase.
-driver = org.postgresql.Driver.
--classpath="C:\db_drivers\postgresql-9.3-1102.jdbc3.jar------.
--changeLogFile="./postgresql_changelog.Xml------.
-url = "" jdbc:postgresql://localhost:5432 / postgres "\"
-username = schema_name_here.
-password = *.
-logLevel = debug.
-defaultSchemaName = Ms.
generateChangeLog
After that, I try to create objects in the Oracle database:
Liquibase
-driver oracle.jdbc.OracleDriver =
--classpath="C:\db_drivers\ojdbc14.jar".
--changeLogFile="./postgresql_changelog.xml".
--URL="JDBC:Oracle:thin:@ip_here:orabeta".
-username = *.
-password = *.
Update
Does not work: ORA-00902
Here is a fragment of postgresql_changelog.xml:
...
< changeSet author = '(generated) Alexey' id = "1409146335011-53" >
< create table tableName = "TABLE1A" >

< forced nullable = "false" / >
< / column >
< column name = "form_fk" type = 'INT8' >
< forced nullable = "false" / >
< / column >
...
I also generate a pure SQL file:
Liquibase
-driver oracle.jdbc.OracleDriver =
--classpath="C:\db_drivers\ojdbc14.jar".
--changeLogFile="./postgresql_changelog.xml".
--URL="JDBC:Oracle:thin:@ip_here:orabeta".
-username = *.
-password = *.
updateSQL > update.sql
Here is a fragment of update.sql:
...
CREATE THE TABLE SCHEMA_HERE. TABLE1A (total_pk form_fk INT8 INT8 NOT NULL,.. .etc);
INSERT INTO SCHEMA_HERE. TABLE1A (ID, $form_id,... etc.)
...
I want to generate the file, in which all the data types correspond to the target database, that is to say I want to create. I can write a simple parser that replace the data types, but this isn't the right solution - can be a lot of data.
It is possible to get changelog from a database and update another database on a different server this changelog RDBMS? I need to get the automatic and Automatic data type conversion generate XML data / SQL output with the data types of target database.
Or maybe there is an option to generate output data types with "abstract"? That is to say with data types that are not in the actual databases, for example, instead of INT8 - whole, etc.
I would be very grateful for the information. Thank you all.

Problems with the Long data type conversion
With the help of Oracle 11 G.
I have a vision where one of the name of the column is of type long, I need to convert in varchar2. I tried using the to_Lob() function, but this error:
ORA-00932: inconsistent data types: expected - got LONG
I followed this article (step 1), which suggests to use to_lob()
My query is:
I tried to convert it into:select item1, -- this is of type LONG item_vat, price_pc_tot, from xd_item_price_view
I am confused about the "-", why he would expect that? Thanks for watching it.select to_lob(item1) as item1_x, -- this is of type LONG item_vat, price_pc_tot, from xd_item_price_view

Sorry mate, just realized that. Yep, this is the one I followed (step 1 using to_lob())

It's a case of 'use' along in a query or search.But you can use to_lob as part of creating a new table.

Topology Manager only allows me the conversion to data type of technology to another. SQL Server has a data type BIT. Default is to convert to a CHAR in Oracle. However, it coverts TANK (1) and the interface fails because the data contains "True" or "False" as values. This forces me to change manually (5) tank & then run again. How can I adjust the settings so that the BIT converts char (5) instead of char (1)?
Thank you
Dinesh.Hi dieng
Go to the topology, under Oracle and create a new data type, name char5 for example.
In the text box NAME and CODE OPPOSITE the word "TANK" in the CODE, let's CHAR5 text box
in the text box: CREATE the TABLE SYNTAX and SYNTAX of DATA WRITEBLE of writing type: char (5)
In the tab "Convet to", you can associate the SQL BIT for this new data type.
This help you?

Hi all
I use VI Scripting in LabVIEW 2010. I need to know the data type of the wire connected to a Terminal. Terminal wire reference gives a property called "Datatype". I thought that this will help me. But he is a variant and how do I actually convert the data to find out the data type. Specifically, I want to make use of data type of cluster. How do I know if the wire is of type cluster?

You want to use the 'GetTypeInfo.vi' VI "LabVIEW 20xx\vi.lib\Utility\VariantDataType\" folder for this!

MSSQL gateway nvarchar data type conversion
Hello
is there a way how to configure the MSSQL gateway to convert the data type nvarchar MSSQL in varchar2 Oracle instead of nchar? Because when converted to nchar, extra spaces are added as nchar is fixed-length, even if I load the data in varchar2 columns.
Thanks for help
PetraNot sure, but it looks like you're talking about Oracle TG4MSQL V10.
Please be aware that all versions of TG4MSQL until V10.2 were desupported by March 15. Thus no additional code changes is made for V10 and frees up the bridge earlier. Customers have to migrate their gateway to the V11 DG4MSQL product that is now available for many platforms of follow-up.
This DG4MSQL also has a mapping to change nchar/nvarchar/ntext data types, the extract of the manual here:
-> NCHAR NCHAR
NTEXT-> LONG (if the Oracle DB character set = Unicode. Otherwise, it is not supported)
NVARCHAR-> NVARCHAR
Nvarchar (max)-> LONG (if the Oracle DB character set = Unicode)Thos V11 gateways are certified with Oracle V9.2.0.8 database versions, 10.1.0.5 and 10.2.0.3 with a compatibility patch but in most applied to the database. This patch is already included in the 10.2.0.4 patches group.
Database v11 works right out of the box. -
Hi experts,

sample:

26/02/2014 02:19:11
This is contradictory.
The timestamps have no any format. (Or, to be excruciatingly correct, they all have the same format, which is nothing like ' MM/DD/YYYY HH24:MI:SS' or ' LUN-JJ-AA HH.MI.) SS. AM FF ' or something else that you use to display the values.) Only those channels have formats like ' MM/DD/YYYY HH24:MI:SS' and you certainly do not want to store information about the dates and times of a string column.
TO_CHAR display a TIMESTAMP in a given format. You can also use ALTER SESSION to change the default format, so that the timestamps are displayed in a given format (unless you are using TO_CHAR to convert them to strings).
For example:
ALTER SESSION SET NLS_TIMESTAMP_FORMAT = "DD/MM/YYYY HH24:MI:SS";
NLS_TIMESTAMP_TZ_FORMAT allows to do the programming for the TIMESTAMP WITH time ZONE SCHEDULE thing.
Your DBA can do something similar to change your system's default format.

What it says on the DATEs apply to parking meters as well.

I have a simple problem.
I have a string type 2D chart. The array is an array with the column names and the lines which are numbers.
I want to extract the lines, but I want them out in the form of numbers that I can make a mount for them online.
I have to select each item and convert the string to a number?
Is there a function that converts a string number (orange line) (pink line)?
Is there a smarter way?

Problem with the data type date

and please help me understand
Function TO_NUMBER to_char TO_DATE, I bit confused in this? Please you can get a few suggestion to laymensterm
Thank you
SureshIf you want to present a DATE data type in a specific format, you will use TO_CHAR.
If you want to transform a (varchar2) STRING to a DATE data type in a specific format, you will use TO_DATE.
Never compare strings to dates
Never compare strings to numbers
You never rely on implicit data type conversions

The code attached is supposed to focus on a cluster and read the name and the data type of each control of the cluster. When I put a timestamp control in the cluster it returns its data in the form of wave type, I thought timestamp has its own data type. I need to get the type of correct data I use this to a database. I need to be able to tell the difference between a timestamp data type and a waveform, because I do not want to insert a data with waveform data type in the database in the form of stamp and I do not want to insert a time stamp in a place where the waveform data must be. Any ideas?
One of the subVIs is password protected, and it is the one that generates the error.
Using the properties class ID and the name class seems to work OK, producing ID = 60 and the class name = AbsTime for the timestamp and ID = 47 and name = WaveformData for waveform control.

Whenever you have a question, please post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and the exact results you want from this data, so that people who want to help you can recreate the problem and test their ideas.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).
See the FAQ forum: Re: 2. How can I ask a question on the forums?
Maybe you want something like:
loged_date between TO_TIMESTAMP (' March 9, 2015 09:00 ")
, ' DD/MM/YYYY HH24:MI:SS.
)
and TO_TIMESTAMP (March 9, 2015 20:00 ')

ADF table filter - date column - in the table data type is timestamp
Hello
I want to filter adf table based on the time stamp column, but unable to do so.
Details.
- The data type of the column (dateAdded) in the database is timestamp.
- the type of this column in the mode attribute is oracle.jbo.domain.Timestamp. and the format is DD/MM/YYYY
- the part of the code in my page jspx is
< af:column sortProperty = filterable "DateAdded" = "true" width = '80' sortable = "true" headerText = "creation Date" id = "c6" >
< f: facet = name 'filter' >
< af:inputDate value = "#{vs.filterCriteria.DateAdded}" id = "id1" > "

< / af:outputText >
< / af:column >
4. everything by filtering this field giving entered in the format DD/Mm/yyyy, the query runs but no change in the result (the value of this field in the table lavel is 10.54.16.000000000 18 June 14 h)
Note: In the interface user, the value of the field is display in the format DD/MM/YYYY.

date and timestamp data type lengths

TIMESTAMP [(fractional_seconds_precision)]
Year, [...] setting. The size is 7 or 11 bytes, depending on the precision. This data type contains the datetime fields YEAR, MONTH, DAY, HOUR, MINUTE, and SECOND. It contains fractions of a second, but does not have a time zone.
However, if I create a table as follows:
create table t9 (timestamp (3) c1, c2 date);
and do:
insert into values t9 (systimestamp, sysdate);
commit;
Select length (c1), (c2) length, lengthb (c1), (c2) lengthb of t9.
I get
