  I have a short form that has optional fields. If the optional fields are not filled in the form, I want to leave the field with a Null value in the SQL db.

• Several lines in duplicate with the null value displayed in the combined analysis rpt

  Dear all,
  
  Our requirement is to display users open tasks (my open tasks) on the home page. So I created a report called open my tasks.
  
  The columns to display are subject, account name, due date, owner. If I use only the 'activities' notification area, and then I can not retrieve tasks that have NULL of the account name. SOD ignore and filter the tasks with the NULL account name if I display the name of the account.
  
  So I used a combined analysis of activity report activity with itself i.e. area statement. All columns except account name in one of them where I used "instead of the name of Account.Account.
  
  It now also displays tasks with NULL account name. But there is another question. These activities when there is an account name, display double - double rows - an account name and othet without account name (for example, NULL).
  
  Please can you help how to solve above or meet the requirement in an alternative way?

• How to use the NVL function to a parameter with comma delimited values

  Gurus,

  It is confusing to me.  I am trying to use the NVL function, but the setting that I'm passing in my cursor contains multiple values with commas.  The NVL function is confused when analyzing the values.

  'Where' cursor clause...

  and nvl (sn.c_attribute1,'x@#$%') in nvl (p_desig,'x@#$%'( )

  translated parameter values...

  and nvl (sn.c_attribute1,'x@#$%') in nvl ('SPRT''GOOD' 'BAD' 'x@#$%') -NVL does not parse the value correctly

  Any idea on how to get NVL recognize 'x@#$%' , if p_desig is null?

             OVER (ORDER BY  LPAD (col1, 2))     AS c2

  If you want to '2' and '3' in front of '10' and 11', then you might consider col1, a NUMBER, rather than a VARCHAR2, or add a constraint (and possibly a trigger) to make sure he always has 2 characters.

  Please include the information and sample version; It's very useful!
  You didn't say if you have Oracle 11.1 or 11.2. From 11.2, there is another way to specify IGNORE NULLS; but as noted above will work in both versions (or any version starting with Oracle 10.1).

• Find columns with only NULL values

  I have a list of tables around 30 in number. Among them i need to generate a report with Table Name and Column Names, for which all values are NULL.
  In other words, i need to find all the columns for which all the values are NULL.
  
  
  I thought of dealing it with cursors, and comparing the total count with null count in each column. But i need to loop "Number of columns" times. Is there any better way to do this?

  If your statistics are up to date, you can use the datadictionary:

  select tab.table_name
  ,      tab.num_rows
  ,      col.column_name
  ,      case
           when tab.num_rows = col.num_nulls then '*100% NULL*'
           else to_char(col.num_nulls)
         end num_nulls
  from   user_tab_columns col
  ,      user_tables tab
  where  col.table_name = tab.table_name
  and    tab.num_rows > 0
  and    tab.table_name IN (YOUR_TABLE NAMES)
  order by tab.table_name, column_id;

• Views of Oracle with parameter with default input values?

  Hello

  As in procedures, can we have a view of oracle which takes the parameter and if the calling routine does not pass the required number of parameter which can be set by default in the view. Thank you!

  1 SYS_CONTEXT - if I store the value of this variable, it will be specific session.

  What "variable" are you talking about?

  'CONTEXT' is NOT a variable - is a data region that contains the pair name = value.

  Contrary to what the other answering machine says that the context variables are "session specific" or not depends on how you create the context. You can create the specific context of the session (by default) or a GLOBAL context. Data in a global context is SHARED by all sessions of the Forum.

  See the diagram of CONTEXT to CREATE the syntax and description in the Oracle documentation

  http://docs.Oracle.com/CD/B28359_01/server.111/b28286/statements_5002.htm

  ACCESSIBLE WORLDWIDE

  This clause means that any context of the defined application namespace is accessible throughout the entire instance. This setting allows multiple sessions to share attributes of request.

  Aware that ALL the VALUES returned by a context using SYS_CONTEXT (see the function description in the documentation of the SQL language) are STRINGS.

  Make sure that you do NOT rely on implicit conversions when the context data items using a DATE value stored in a string.

• Number of rows in each partition is displayed with a NULL value for a table partitioned in user_tab_partitions. Why?

  I created a table and partitioned on the date of the entry and added a local partitioned index.

  Now, I use a query to extract "num_rows" of user_tab_partitions to know the number of rows in each partition.

  Getting this value as null num_rows, wonder why?

  After looking to explain the Plan after interrogation ("select * from my_table1 where entry_date = 1 January 2015" ;))

  to find out if she actually partitioned table and its data in different partitions, I interpreted in effect because the query plan had a line like Partition_range (Single).

  My Question is:

  (a) is actually partitioned data (have I misinterpreted the Explain plan)

  (b) why is the num_rows null column in the query (Pasted below)

  (c) also in addition what difference it would have been if I had created a Global Index instead of the Local Index in my case?

  The following code Snippet:

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

  create the table my_table1
  (
  roll_no number constraint my_table1_pk primary key,
  date of entry_date
  )
  partition of range (entry_date)
  (
  PARTITION data_p1 VALUES LESS THAN (TO_DATE (December 31, 2014 ',' DD-MM-YYYY ""));
  PARTITION data_p2 VALUES LESS THAN (MAXVALUE)
  );

  
  create an index only my_table1_indx on my_table1 (entry_date) local;

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

  I now insert two lines:
  insert into my_table1 values (1, to_date ('01-01-2015', ' dd-mm-yyyy'));
  insert into my_table1 values (2, to_date('01-02-2015','dd-mm-yyyy'));

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

  These have been inserted successfully, now using the query below shows num_rows column as null. I don't know why?

  SELECT table_name, num_rows, high_value, nom_partition
  Of user_tab_partitions
  where table_name = 'MY_TABLE1 '.
  ORDER BY table_name, nom_partition;

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

  
  

  (a) is actually partitioned data (have I misinterpreted the Explain plan)

  Yes, it is partitioned. You can query this particular partition SELECT * FROM my_table1 (data_p1) PARTITION to check that.

  (b) why is the num_rows null column in the query (Pasted below)

  As already mentioned that you have not collected statistics.

  (c) also in addition what difference it would have been if I had created a Global Index instead of the Local Index in my case?

  In fact, you have created two types of indexes without knowing (can be)! One is not partitioned (although this column is not partition key) and another is partitioned (LOCAL). They are MY_TABLE1_PK and MY_TABLE1_INDX. You can check that USER_INDEXES.

  You can read this article to get an early jump on the partitioning of decision. Partition: Partition decisions

• Remove data with null value

  Hello

  I'm using Oracle 11 g. I have a table with an id of 3, node, the value column. Combination of the column id and node, that must be taken account for deletion on the registers.

  Here, I need to delete lines with the NULL value in the value column. If for a combination of id and node with non-null values, then I need to delete rows with a null value for this combination.

  If the combination of id, node is not null value then this records should not delete.

  Below table, I need to remove the second row, for which is a value not zero VOICE CAL '10' is there, so I need to delete the row with null values. (VOICE, CAL, NULL)

  Network, FL, there is no value is non-null then I should NOT delete this line.

  This table is to have 100 s of this association, we can delete data in a single delete query?

  Or how I can delete rows with nulls for this combination.

  You can do this in a single DELETE statement (it is not a request), using an EXISTS or IN the subquery.  For example:

  REMOVE table_x m

  WHERE the value IS NULL

  AND THERE ARE)

  SELECT 0

  FROM table_x s

  WHERE s.id = m.id

  AND s.node = m.node

  AND s.value IS NOT NULL

  )

  ;

  If you would care to post CREATE TABLE and INSERT instructions for the sample data, and then I could test it.

• check NULL values with expressions

  I'm having a problem with an expression that I work with.

  I'm trying to produce a dynamic graph (among other information) that seems to be controlled by a stream - stream artificial is created by a handful of sliders and a wiggle expression.

  The chart is a simple graphic line which works very well. It is created with a null value (MarkPos) that the position is controlled by Captain wiggle expression that I've mentioned before, that follows.

  This next bit is where I have problems:

  I want to score minimum or maximum, the line has reached on the chart by moving a dotted line, one for weak points and the other for the top.

  Focus only on the bottom line;

  I have the following expression associated with the line, which brings together the current position of the value null (MarkPos) and compared with the current position of the line to see if it has all moved further away down, if she has it moving the line to the new pos are lower. However, all that happens is the line following the null value.

  x = thisComp.layer("MarkPos").transform.position.valueAtTime (time) [1];

  y = transform.position.valueAtTime (time) [1];

  z = transform.position.valueAtTime(time-thisComp.frameDuration) [1];

  If (x > y) {}

  [0, x]

  } else {}

  [0, z]

  }

  After a lot of debugging, I now know the issue is with the else statement - what his weight is compensating the to the high movement frame by frame 1 - so how do you define an order of "keep your current position in y ' in this case?

  [0.1] just it back to its original position and it is not possible to just have the ' if(x>y) {[0, x]} "bit without the"else {}.

  Suggestions fo how to fix this, or a better way to do it?

  This should give you the value of y min:

  p = thisComp.layer("MarkPos").transform.position;

  minVal = 999999;

  for (f = timeToFrames (time); f > = 0; f-) {}

  minVal = Math.min (digraph, p.valueAtTime (framesToTime (f)) [1]);

  }

  [value [0], minVal]

  and this should give you the most:

  p = thisComp.layer("MarkPos").transform.position;

  maxVal = - 999999;

  for (f = timeToFrames (time); f > = 0; f-) {}

  maxVal = Math.max (maxVal, p.valueAtTime (framesToTime (f)) [1]);

  }

  [value [0], maxVal]

• Restrict null values

  Hi all
  
  Can I restrict null values when passing parameters in procedures. can someone explain to me with a small example

  Hello

  Pascale says:
  The table does not allow null values. It throws an exception when the value null is passed IN parameter

  Are you talking about raising of arguments passed to a procedure or a table?

  If a column in the table has a NOT NULL constraint, an error will be reported in the world tries to add a NULL value in this column, or if someone tries to change an existing value with a NULL value.

  I don't know anyway auto to force an error when a procedure is called with a NULL argument. There may not be any built-in mechanism because it is so easy to test the NULL at the beginning of the procedure and explicitly to trigger an error.
