Char to Varchar type Conversion

• Table attached using CHAR and VARCHAR data indicator type

  Hi all
  
  I would like to bring together 3 tables, but I am unable to get a perfect match (using =) between the CHAR and VARCHAR data type.
  
  A command exists to get impartially all data treated as CHAR or VARCHAR?
  
  Thank you in advance for your help!

  Apart from the fact that it's the wrong forum...
  Just use:
  Trim (your_char_column) = TRIM (your_varchar2_column)
  However, it is bad practice because it is a showstopper for the optimizer and will probably lead to poor performance.
  Consider re-thing your data model PK - FK relationships.

• 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.

  Please, help me understand.

  ACCESS (Index Scan) - Oracle tries to use an index one try to access a table row that they are interested.

  FILTER (full table scan) - Oracle has no any tool to directly get to the table of ranks it is interested in, so it must pass all the lines and then filter the rows that match the main condition.

• 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?

• Lack of Audio in DV file Type conversion in Streamclip

  Hi all

  Thanks in advance for your help.

  I would ask your opinion on the conversion of VOB files from a file type that I can edit with Adobe Premier elements v13 software:

  My goal is to use a file type that will provide the best video quality while being effective to change.  I use "MPEG Streamclip", and when I convert in the file type "DV" I lose sound completely.  When I converted to "MPEG with MPEG2 audio" the sound is OK but I understand that this type of file will be less effective to change.

  Do you know why I'm losing audio when converting to the file type "DV"?

  How can I get the converted file to the recommended with the audio intact preserved DV file type?

  Thank you

  Scott

  Try my suggestion. I think that you will find it easier and better.

  With respect to the duty to work with several VOBs, which can be simplified to. In the future, when you want to use the video to a DVD, place the DVD in the hard disk of your computer and use Add Media / camera DVD or disc to "rip" files from the drive on your computer. You can even choose to have all files on the disc directly added to your calendar. It is much simpler and it helps you to avoid dealing with the VOB files that do not include the video you want or don't include any video at all.

  Of course, I guess that the video that you are ripping the DVD is not a commercial DVD. Protected DVDs, commercial have other issues.

• 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())

• What is the point of type conversion of forms, rather than just flattening at required resolution?

  OK, this may seem a stupid question. Lets say that I see a three-pronged in Photoshop. The printer asks that the drawings are conducted on a 300 dpi resolution.

  What is the point in the conversion of any type of forms before the registration or embed fonts when I can flatten just my design at 300 dpi as a whole? Don't go printing do anyway... flatten just my design? Or they print type at a resolution higher than the portions of the frame of the drawing or model? He mistook me for too long. I hope someone can clarify this. Thank you

  300 ppi measurement is used for the midtones (aka filtered) images. Text is often not tracked so this resolution does not apply. You want a higher resolution (obtained by keeping the text in vector format) to keep a clear text.

  When sending art to a printer or to the bottom of the page-assembly line, it is ideal to save in PDF format that it will retain the direct type of Photoshop as a material of vector fonts.

• 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!

• USB Type C to Type conversion

  Hi all. I just bought a hard drive Seagate Innov8 USB powered. The Innov8 has only a USB port 3.1 Type C and my Mini Mac has USB 2.0 inputs Type A. I have connected to them using the converter, but Seagate red light remains lit, indicating low battery, and the Seagate drive does not appear in the Finder. Y at - it some technical problem here I'm not aware of, or is it likely to drive Seagate is broken? USB is backward compatible, but it is possible the Mac Mini isn't providing enough power for the Seagate

  Thanks for any help.

  What model Mini?

  What specific "converter"?

  Yes, some USB ports do not provide sufficient power. The USB 3 / 3.1specs require the port to provide more energy than a USB 2 port.

• Table data type conversion

  I have a simple problem.
