• convert long varchar use views

  I want to get varchar2 column search_condition (dba_constraints), but get an error:

  Return substr (l_data, 1, 4000);
  end;
  
  
  Can not you advide me how to convert.

  DBA_CONSTRAINTS is a view based on many SYS belonging to tables. So there is no own ROWID. This is why your code does not work. Now the combination of the owner, table_name, constraint_name is unique, so that you can change the function to use instead. Also, search this forum for other solutions with long

  SY.

• Long Varchar conversion?

  OK, so I'm trying to analyze the source code of compiled views. so I'm going with a simple:

  long value 1000000

  Select the text in dba_views where view_name = "DBA_VIEWS;

  I use DBA_VIEWS just to keep the results to short, because everyone has it... and it's mildly amusing to choose from to

  In reality, I will have a wider where clause.

  So, now I want to search the text for some references, diagrams and tables. So let's just look at "sys."

  Select text

  from dba_views

  where view_name = "DBA_VIEWS.

  and instr (text, 'sys') > 0;

  ERROR on line 4:

  ORA-00932: inconsistent data types: expected NUMBER got LONG

  Large.

  OK, so I'm doing a research to try to understand to get 'convert' a long varchar and each solution according to me, is to 'migration' of the data. In other words, it assumes that you have created your own TABLE with a LONG data type, and the need to MOVE in another TABLE. Which is not even close to what I'm doing here. I question the fair data.

  Then I come across this little gem:

  http://asktom.Oracle.com/pls/Apex/f?p=100:11:0:P11_QUESTION_ID:839298816582

  Candy!

  So I give that a try:

  (I've renamed its function, but has not changed any other logic, or another change of name).

  FUNCTION to CREATE or REPLACE f_long_to_varchar

  (p_tname IN VARCHAR2,

  p_cname IN VARCHAR2,

  Select f_long_to_varchar (text) in the dba_views where view_name = "DBA_VIEWS;

  ERROR on line 1:

  ORA-00997: illegal use of the LONG data type

  Large. So, does anyone have other ideas?

  How can I query the dba_views and sweep the text as a varchar field?

  Can it be done without moving the data to a temp table? Or the other case - how to do?

  I'm coming up absolutely empty on that.

  Thank you!

  Without creating additional objects, you can try the following query. It supports the content of greater than 32 KB size.

  However, it is quite slow.

  Select v.owner

  v.view_name

  x.text

  from dba_views v

  , xmltable ('/ LINES/LINES/VIEW_T ')

  passage (document xmlparse

  () DBMS_METADATA.get_XML

  schema-online v.owner

  , object_type-online "VIEW".

  name-online v.view_name

  )

  correct

  )

  path of clob columns text "TEXT".

  ) x

  where instr (x.text, 'QA') > 0

  - and v.view_name = 'DBA_STREAMS_COLUMNS. '

• Convert long DDMMYY

  Hello

  I am getting server date string in todays date DDMMYY format e.g. is 180811. I want to convert long. I used HttpDateParser, but it does support this format. How can we achieve this?

  Thank you

  @simon_hain: thank you. Now it works very well...

  String PROMOTIONDate = "20";
  Nouvelle_date = Nouvelle_date + date.substring (4, 6) + "-" + date.substring (2, 4) + "-" + date.substring (0, 2);

  but I'm not loving the manual scan.

• ODI - in collaboration with Long Varchar and CLOB

  Hi all

  I have a source table 'A' that contains a column of type LONG VARCHAR, I need to map to a CLOB column in the table target 'B '. The column can be mapped just without any type of 'distribution' of the LONG VARCHAR in the CLOB column?

  Thanks in advance

  Eduardo

  Even I don't think that you need the TO_CHAR.

  On what task it block in operator? What is the code generated for this task?

• procedure for converting long on the clob type

  Please you need to process long migrate on the clob, with variables type
  V_SRC_TABLE (LONG) to V_TRAGT_TABLE (CLOB)
  
  SOURCE AND TARGET HAVE TWO COLUMNS
  
  SOURCE_TABLE
  VARACHAR2
  LONG
  
  
  TARGET_TABLE
  VARACHAR2
  CLOB

  Hello

  Assuming you want to convert data always source_table target_table knowing the column names, let's say:

  SQL> CREATE TABLE source_table(col1 VARCHAR2(10), col2 LONG);
  
  Table created.
  
  SQL> CREATE TABLE target_table(col1 VARCHAR2(10), col2 CLOB);
  
  Table created.
  

  You can simply copy the data using SQL:

  INSERT INTO target_table SELECT col1, TO_LOB(col2) FROM source_table;
  

  Or, as a procedure:

  CREATE OR REPLACE PROCEDURE migrate_to_clob IS
  
  BEGIN
  
    EXECUTE IMMEDIATE 'INSERT INTO target_table SELECT col1, TO_LOB(col2) FROM source_table';
  
  END;
  

  It will be useful.

• CONVERT varchar into money

  Can someone help me with the syntax on how convert data type varchar data type money. I get the following error message:
  
  [Macromedia] [SQLServer JDBC Driver] [SQL Server] Denied the implicit conversion of the data type varchar data type money, table 'tableName', column 'columnName '. Use the CONVERT function to run this query.
  
  Any help would be appreciated! Thank you.
  SLL

  The error is caused by the use of single quotes around #form.price #. Single quotes tell sql server to deal with the #form.price # as a string (varchar) value. Although sql server can implicitly convert some values from one data type to another is not automatically converted to varchar in type money.

  Assuming that you have already validated the value #form.price #, get rid of the apostrophes or better to use cfqueryparam with the proper cfsqltype. (I think that's cf_sql_decimal)

  -It works
  Update @tblName
  fixed price = 10.00
  where id = 1

  -It works
  Update @tblName
  fixed price = cast (' 10.00 ' as money)
  where id = 1

  -It's not
  Update @tblName
  fixed price = '10 h 00'
  where id = 1

  -using the cfqueryparam
  Update @tblName
  package price =
  where id = 1

  Hello

  LONG is an old format with a lot of limitations that will make your life miserable. If you need to copy your table to another, take this opportunity to convert long on the CLOB type using the to_lob() function.

   create table t1(id long);
  
   create table t2 (id clob);
  
   insert into t2 (id) select to_lob(id) from t1;

• Why is there a long column in user_tab_partition?

  Hi all

  While I was working on a project of partitions, I realize that I had to work with long files.

  It turns out I realized that it was quite obsolete:

  "Why do you have a column of LONG data type?

  LONG data type has been deprecated since CLOB were introduced about 10 years ago. Oracle does not recommend you use LONG data type and it is there than to support backward compatibility. »

  Not all wrong, by the data dictionary seems full of craft:

  http://docs.Oracle.com/CD/B14117_01/server.101/b10755/statviews_1058.htm

  So I wonder, because the effort is given to discourage and de-motivate people from using LONG data types, why oracle is not refresh its data was thinking?

  Because I wanted to be to operate in this column (do a SHIFT to see the high value and low value of the previous score), I had huge problems to do.

  How could have out us of Oracle on the topic?

  Not being don't not an Oracle database designer, I can't speak for Oracle, but I see that the user_tab_partitions of view and it relies on the base tables have been designed well before that Oracle introduced the LOB data type.  Change the data type of a database table, we hear all code that refers to this column must be updated.  New SYS objects use LOBS, but most of the time Oracle has not returned and modified existing objects.  Maybe in version 20 (i.e. at some point remote in time).

  - -

  IMHO - Mark D Powell-

  PS - A change to a base table data type would be also means existing data on the upgrade will need to be converted.  Potentially existing a requirement of your time which is another reason to not change the data type.

• How to insert the value of a LONG data type?

  Hi all
  
  Developers what to change the type of data in the PRODUCTS table.

  Edit the product table change (long descr);
  Insert into select product * from product_bak;

  Use TO_LOB to convert long on the CLOB type, then use TO_CHAR to convert CLOB VARCHAR2.

• Query a date in a varchar field

  I'm doing a simple query...

  Count the number of records in a given month.

  I use variables in the URL and use this query (MSSQL)

  
  SELECT recorddate FROM sometable
  WHERE Year (recorddate) AS ' #Url.year # '.
  AND Month (recorddate) AS ' #Url.month # '.

  It should work in theory, I think, but the problem is that the date field is of type varchar (although all records have a time stamp that has been added as:)

  < INPUT type = "hidden" name = "recordate" value = "#Now () #" >

  I'm not advanced in ColdFusion, so I hope someone can help me... Is there a simple way to do this?

  Thank you!

  I agree with Dan Bracuk you need to store your date values in a date column.  It would be for SQL server DATETIME, SMALLDATETIME, or DATE depending on your version of the server and the requirements.

  As a quick fix, you can use a derived table that converts your varchar in date column values.  Note that this must be used as a work around until you can update your table to use a date column.  This request will probably not run well on large data sets.  You must also use the CFQUERYPARAM tag to avoid SQL injection vulnerabilities.

  
  
      SELECT recorddate
       FROM
       (
           SELECT CONVERT(DATETIME, recorddate) AS recorddate
           FROM sometable
       ) AS Q
       WHERE Year(recorddate) = 
           AND Month(recorddate) =
