• 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 '?

• Table data type

  Is there any equivalent data type to create a table inside a stored procedure or a package, and the table is only valid in the stored procedure or package.
  Something like this [http://www.developer.com/db/article.php/3414331/Using-the-Table-Data-Type-in-SQL-Server-2000.htm] what we have in sql server.
  
  I'm pretty new in Oracle world.
  
  Any help will be much appreciated.
  
  Thanks in advance.

  Yes... You can declare a record type in the package body

  TYPE rec_type () IS RENDERING
  NUMBER of col1,
  col2 VARCHAR2 (2 CHAR)
  ....
  );

  then simply declare a type of table top the record type

  TYPE tab_type IS TABLE OF THE rec_type;

  You can make statements within the body to keep it private, or in the spec to make it public

  It could be that useful...

• 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?

• 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.

• Variant data type conversion

  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?

  Thanks for any help.

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

  I would recommend installation of this Package of VI because it adds these features to pallets:

  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.

• Data type conversion

  Hi experts,

  ... 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.

  SQL> column phone format 999999999999; 
  

  tells SQL * more to display a numeric column named PHONE that is selected using up to 12 digits before moving on to scientific notation. It's the same way that you can control the width of a column of basic text, i.e.

  SQL> column table_name format a10;
  SQL> select table_name from user_tables
  

  Displays the TABLE_NAME column using 10 characters per line. Assuming that you have a long table names, they will be wrapped to the next line.

• Change the length of a Table column (CHAR data type)

  Hi gurus,

  SQL > select * from version $ v

  BANNER

  ----------------------------------------------------------------

  Oracle Database 10g Release 10.2.0.3.0 - 64 bit Production

  PL/SQL version 10.2.0.3.0 - Production

  CORE Production 10.2.0.3.0

  AMT for Linux: release 10.2.0.3.0 - Production

  NLSRTL Version 10.2.0.3.0 - Production

  I need to increase the length of a CHAR of a table data type column (currently it's tank (3) and you want to change to char (4)). Here are more details on the table:-

  • Contains more than 20 million lines.
  • Table contains several indexes.
  • Table is referenced by several tables (about 60 tables) and it refers to several tables (about 3)
  • Table has 4 complex triggers. Triggers call procedures and packages.

  What I've tried so far

  
  

  1 disabled all triggers and ran ALTER statement to increase the length. It took hours and did not finish in a reasonable amount of time, even if no error, but it took more than 12 hours.

  2 tried DBMS_REDEFINITION package but it does not work with the standard version of Oracle 10 g.

  I think to try next

  I think same Optics:

  Say my name of the existing table is OLD_T1 where the length of column need to increase

  -Create a copy (with increased column length) table of OLD_T1, Say NEW_T1

  -Move data from in OLD_T1 to the new table NEW_T1

  -Lower OLD_T1 (or rename it to OLD_T1_TMP)

  -Rename NEW_T1 to OLD_T1

  -Create all indexes, triggers, constraints etc..

  I wish to confirm, if my approach is correct? Or someone has a better idea to do this?

  Please note: I know that the CHAR data type gives the problem but it is an old system and I don't have authority to change the design of database.

  Appreciate any comment/suggestion

  Thanks in advance

  > I mean, can any application break if it depends on fixed-length?

  Yes, because the code can be expected completed on the right areas.

• Tables and table data

  Hello-

  How is it when I create a node of a table property value and build a table of this node of property value, it gives me an annexed table?

  I tried indexing in this table twice for a single row of values, but when I try to compare the 1 index of this row in the table with the

  first index value from an array of the same size, the equal sign will not indent the table created index from the table. I see that the

  output wire is pink, which means that the value is considered as text... How can I convert that to a number so that I can compare the first value of a line

  in a table of the first value of a picture of a line to determine if they are equal? Array index is fed data points from

  a graph and once this 1st value of the array index is the first index value of the row in the table, I hope to have the index given in the table

  turns green when there is a football game. Thank you.

  Hello

  I'm not absolutely sure I knew you. Displaying a VI or a screenshot could be useful...

  However, attached, you will find a simple VI compare the first value of a table wanted the first value of a table row.

  Note that the table data type is string, not digital. No matter if you put numerical values in the table there are always string. A conversion is necessary to compare the values in array of numeric values.

  The values in the table are displayed as a 2D array in which the first dimension contains the lines (x).

  I hope I could help you with that.
