• Find SQL hash value statements

  Oracle Database 10g
  Red Hat Linux
  
  One of our developers wants to recover the full 3 days sql statements. I have the hash value of statspack at this time.
  
  I get the following.
  
  Select SQL_FULLTEXT from v$ sqlarea where HASH_VALUE = 98832848;
  
  no selected line
  
  
  Is the statement that I used is the right? Is - this way? I get no return, does that mean that these SQL statements have aged?
  
  This database is only about 16 GB and SGA Total is only about 1.3 GB.

  If its 3 days it would be aged. Since you're on 10g, try mark dba_hist_sql_text who would be the oldest stored sqls provided your AWR retention period is in order.

• HASH value in a custom report

  Hello

  I created a custom report for Top SQL on a monitored by Foglight Oracle DB. During the creation, for the input data, I check the HASH value. OK, it shows HASH values, but the format is not identical to the database.

  In the database, I have for example 432647

  but in Foglight report I 45 M or 67G.

  I am amazed. What is the problem with my report?

  Thank you.

  It looks like an inappropriate rendering engine has been configured for this area of the custom report. Did you leave the default rendering engine? If so, try some of the other converters and see if you get a better result.

  Kind regards

• Updated with the hash values column

  Hi all

  I have a requirement to add a column to a table and fill it with the hash values. The table contains an xml column and hash value of this column need to be filled to newly added column. I think that the ora_hash function will not support the xml type column. Just tested with the following script and it works.

  update TBL_COMPONENT_XSL set hash_val = ora_hash((SELECT TCX.COMPONENT_XSL.getStringVal() FROM TBL_COMPONENT_XSL TCX where rownum =1));
  

  can you please suggest me how to fill the column with the hash values.

  SQL> desc TBL_COMPONENT_XSL
   Name                                      Null?    Type
   ----------------------------------------- -------- ----------------------------
   COMPONENT_XSL_ID                          NOT NULL NUMBER(18)
   LINE_OF_BUSINESS                          NOT NULL VARCHAR2(30)
   ORDER_SOURCE                              NOT NULL VARCHAR2(10)
   COMPONENT_NAME                            NOT NULL VARCHAR2(30)
   COMPONENT_SCHEMA_VERSION                  NOT NULL NUMBER(9)
   ACCESS_LEVEL                              NOT NULL VARCHAR2(30)
   COMPONENT_XSL                             NOT NULL SYS.XMLTYPE STORAGE BINARY
   DESCRIPTION                               NOT NULL VARCHAR2(200)
   HASH_VAL                                           NUMBER
  
  

  HASH_VAL is the newly added column.

  Thank you

  Mani

  What happens if you try with:

  update of TCX TBL_COMPONENT_XSL set hash_val = ora_hash (TCX.COMPONENT_XSL.getStringVal ());

  update of TCX TBL_COMPONENT_XSL set hash_val = ora_hash (TCX.COMPONENT_XSL.getClobVal ());

• Hash value of plan of

  Hello
  I'm in the database to version 10g, 10.2.0.4.
  and I have a query that uses sometimes ok execution plan and sometimes poor execution plan.
  Everyone that plans have different hash values.
  Can I somehow map this query for hash value of plan ok ok?

  You should see child_number different values for different plans. The creation of outlines is a simple:

  BEGIN
    DBMS_OUTLN.create_outline(
      hash_value    => 3909283366,
      child_number  => 0,
      category      => 'SCOTT_OUTLINES');
  END;
  /
  

  The example comes from Tim Hall's article: http://www.oracle-base.com/articles/misc/outlines.php.

  Ultimately, an outline is only a bunch of advice internal sql.

• Plan of the hash value for two queries!

  Hello
  DB: Oracle 11g (11.2.0.3.0)
  OS: RHEL 5
  
  I have two question:
  
  1. can two queries have the same hash value of the plan? I mean I have here are two queries:
  
  SELECT /+ NO_MERGE * / MIN (payor.next_review_date). *
  * Payer from *.
  * WHERE payor.review_complete = 0 *.
  * AND payor.closing_date IS NULL *.
  * AND payor.patient_key = 10; *
  
  and
  
  SELECT MIN (payor.next_review_date)
  * Payer from *.
  * WHERE payor.review_complete = 0 *.
  * AND payor.closing_date IS NULL *.
  * AND payor.patient_key = 10; *
  
  When I tried to examine the execution plan for the two motions, the hash value of the plan remains the same. This means that implementation plan for both queries are same? If so, then how Oracle includes or changes to the execution plan based on hint. If not, then what hash value of the plan represents?
  
  2. If the plan with suspicion, and without suspicion is identical except for a given query except the number of lines and bytes. Do you mean this query with fewer lines and scanned bytes is better?
  
  Thanks in advance

  >
  Yes - as already said - but it's not just because of tips.

  Here is the example code that I use to show that Oracle does NOT simply use a text version of the query that you propose and compute a hash of it.
  These two queries are radically different but have the same hash value; Oracle are not different at all.

• explain the analysis analyzed, plan implementation, the hash value code

  whts the hash value, code analysis, plan to run?
  can we see the hash value?

  The analysis is the first step in the treatment of any statement in an Oracle database. Statements are broken down into its components and so DML or DDL statement type is determined and different controls are carried out on this subject. A statement must be evaluated and validated before execution. Oracle evaluates statements for syntax, the validation of objects and the privileges assigned to the user.

  Oracle hash value will check privileges for any SQL statement, and then assigns a number called the hash value SQL for the SQL statement to check whether or not this statement exists in memory

  The statement execution plan, will select the best methods to access the SQL statement

  filed Bug 19844303 - SQL % ROWCOUN RETURNS a VALUE INCORRECTE

• The coldfusion.sql.QueryTable value cannot be converted to a number

  Hello

  I have two queries, in two different functions, who both return the SUM of a column based on the values of the arguments

  I need to subtract query from a query of 1 2.

  The arguments for the two motions are passed using the CreateObject function

  < cfset qry1 = createObject ("component", "components.adminobjects"). Func1(#argument1#,#argument2#) >

  < cfset qry2 = createObject ("component", "components.adminobjects"). Func1(#argument1#,#argument2#) >

  Queries executed accordingly and returns the results accordingly.

  The problem occurs when I try to calculate by subtracting the 2nd request form 1.

  So, to get the results I need, that's what I do:

  < cfset results = ' #qry1.sum # '-' #qry1.sum2 # ' >

  < cfoutput > #results # < / cfoutput >

  When I do this, it is said:

  The coldfusion.sql.QueryTable value cannot be converted to a number

  I don't understand, it is because when I exit #qry1.sum # or #qry1.sum2 # I get the numbers right and they are numbers, but when I do some math on them, I get the error.

  Any ideas?

  Thank you.

  Assuming that the qry1 object has a column named "sum1" and "sum2" try:

  Also note that the "sum" is a reserved word, try to change the column "sum" "sum1".
