• 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" >

  < column name = "total_pk" type = 'INT8' >

  < 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.

  Why not to use pg_dump to extract the schema in a file of script that you can then 'change '?

• 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:
  

  select
  item1, -- this is of type LONG
  item_vat, 
  price_pc_tot,
  from xd_item_price_view 

  I tried to convert it into:
  

  select
  to_lob(item1) as item1_x, -- 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.

  >
  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.

• DATE in TIMESTAMP data type conversion

  Hello
  
  My 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!

• Control data type conversion

  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?

  If your arguments start_date and end_date DATE data type, then you can simply use TRUNC

  INSERT INTO temp1(no)
  SELECT CASE WHEN TRUNC(sysdate) BETWEEN TRUNC(start_date) AND TRUNC(end_date)
               THEN NVL(TO_NUMBER(org_id),0)

• 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
  Petra

  Not 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.

• Table data type conversion

  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?

• Data type conversion

  Hi experts,

  Try to convert the varchar2 systimestamp date

  EX:

  Entry (varchar2) - 26-FEB-14 02.22.45.231073 PM

  Thanks in advance

  Hello

  ... Target table:

  OUTPUT SHOULD BE:

  I need the output to the format MM/DD/YYYY HH24:MI:SS

  sample:

  26/02/2014 02:22:45

  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.

• Gets the data type variant for the selection of cases

  I don't ' know much about alternative, so I'll ask as many questions as possible on this subject.  If I have a table of varying, and each of these variations has been converted to a different data type.  This table will be the clue to a for loop and each item will be handled in a case inside the loop structure for.

  The issue is that I would like to take the variant data type, convert enum and use it to select the box on the structure of the case.  How do I do that?  Or what is the best way to do it?

• Variant to Boolean conversion

  Hello

  Also, we get a very unfortunate mistake of Boolean variable reading of a PLC register that is automatically converted to a Variant. And therefore, when wire us a Boolean indicator (led) it gives me the error 91: "the variant data type is not compatible with the data type of wired for the input type.

  Some people have had the same problem but I'm not a little to get around / solution !

  The intervening variable is down, "F3 BLOKKAGE SCHROEF 2 OK.

  Thanks for help

  In addition, you really should provide the data type during the conversion of a variant.  There is an entry on the top of the variant data Type node.

  

• variant data

  I have a data type variant. See attachament. I tried to use varying data for each values within the Variant.

  Is it possible to extract or obtain values of each in a variant data type? How do you usually?

  Thank you

  You must connect a data type to the variation of data to determine the conversion. /Y

• Scripting-Terminal of a "Data Type creation.

  I have a script function that is supposed to create a constant (think melting or Variant data type) a receiver provided. He then connects this constant to a designated terminal.

  I get this error when I try to catch the terminal of the object that I just created. (just before the error dialog box that I placed)

  

  I tried a handful of things, and I have a hypothesis for now. LabVIEW handed me a constant with a command reference.

  More specific error when I try to make a constant. Guess it makes sense because it does not move to the top or to the bottom of the tree.

  Has used the 'create data type' incorrectly? Is there a way to force the referral to continue to point to the object but to be recognized as a constant?

  Thank you

  This is a known bug with the creation of the method of Data Type. The workaround prescribed, it is exactly what you've done... convert the order for GObject reference, then convert this constant reference.

• Variant data vs Flattened to string

  Hi all

  I haven't worked a lot with the type of a variant in LabVIEW and after having read about a few items, I wonder what is the fundamental difference between a flattened chain and a variant data type.

  I read somewhere that the variant data types also contain metadata that includes the data type there and again we need to wire the data type to the function 'variant data. Why?

  What is the case of the use of the variant data type? I think essentially to a use case where flattened string cannot do a job which variant data type can do.

  Thank you

  Use the Set attribute varying function.
