• Using "between" for the literals inside the 'where' clause

  Hi all
  I have run the following queries in 10.g HR XE diagram example:
  The first query is limited by characters between 'I' and 's', where the second query is limited to words between "IT" and "Sales".
  
  My question is, how did the first query will not return not row "Sales" as it does in the second? I don't understand not how 'between' works on string literals. Help, please.
  
  Kind regards

  Imagine how these words are ordered in an encycopedia or a thesaurus.

  10. public relations
  11 purchase
  12 recruitment
  13 S
  14 sales
  15. management system

  "S" is ordered before "Sales". Between includes everything including the lower and the upper limit (row 1-13). It does not include things in order AFTER the upper limit (line 14 ++).

  So, if you want to find everything that begins with "S", then you have several options.

  (1) show all after including 'I' but before the "T" (not including T)

  select department_name
  from departments
  where department_name >=  'I'
  and department_name < 'T'
  order by department_name;
  

  or
  (2) show all what the first letter between "I" and "S".

  select department_name
  from departments
  where substr(department_name,1,1) between 'I' and 'S'
  order by department_name;
  

  Almost always, I would choose the first option. Usually it's faster as a clue to the name of the service can be used if there is a.

  There is a third option. But it's kind of stupid and incomplete. You could add the last string you can imagine as the upper limit of between it the function.

  select department_name
  from departments
  where department_name between 'I' and 'Szzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz'
  order by department_name;

• DECODE does not work in the WHERE clause when subquery returns more than one line

  Hi gurus,
  
  I want to write a query against the table CCENTERS (Script given below) and wait for the following result:
  
  1. in the transition from a value of 0 for the ID, it returns all the rows in the table.
  2. in the passage of one value other than 0, it returns the row corresponding to the given value and all its records of the child.
  
  CCENTER has parent-child relationship in the column ID and the BASE. I use a query with the DECODE function. but the function in the WHERE clause is not capable of managing the subquery with multiple lines of DECODE.

• by the way check box values in the WHERE clause

  Hello

  I created a data block - 'CONTACT' (block of data in database)

  and has an element of database - 'Code', 'Descr '.

  The number of records displayed has the value 5.

  When enabled - value 'Y '.

  Value when disabled - n

  Box mapping of other values - "unchecked."

  
  

  I write the code inside "WHEN the BUTTON PRESS. My main goal is to return the number of records from

  According to several conditions and one among them is the CODE which can be single or multiple based on the checked checkbox.

  The requirement is when I check one or more boxes, I should pass the "Code" element values in the WHERE clause.

  I tried to use the simple loop but things havmt worked as shown below.

  The next_record refers to the COCHEE BOX as well, and thus return all the eventhough lines if it is not checked.

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

  -LOOP
  

  IF: contact.cb = 'Y' THEN

  LOOP

  IF p_where is null then

  p_where: =: contact.code;

  on the other

  p_where: = p_where | «, » || : contact.code;

  end if;

  When the output: system.last_record = "TRUE";

  next_record;

  END LOOP;

  end if;

  -END LOOP;

  MESSAGE ("p_where :'|| p_where);

  MESSAGE (' ');

  END;

  
  

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

  And even if I write the LOOP before the first CASE, it returns me the current value and move to the last record.

  Please suggest

  Try something like this:

  FIRST_RECORD;
  
  LOOP
  
    IF :contact.cb = 'Y' THEN
      IF p_where is null then
         p_where := :contact.code;

• Try adding conditions to clause "and" stored in the table for the where clause, unknown syntax

  I am trying to add additional segments to the 'where' clause, and I don't know exactly how to proceed. I am currently using another table to search for keywords and sometimes there aren't everything. I use this table containing the key words to search the description and associate a symbol with a path.

  The code loops through the keywords with the keywords most associated and try to find links to a symbol then excludes those and search for symbols that correspond to those with less keywords and all. I am able to do this with 6 queries and manually changing the arguments, but I want to loop together so that if the changes need to be made in the future, I won't need to go digging in the code.

  Thanks, but that's ok. I already have a solution for this.

• using case when statement or decode unfavorable in where clause

  Hi the gems...

  I try to use when case statement in where clause of a select query.
  
  
  Select cr.customer_name. ' - ' || CR.customer_number as cust_name,
  CR. Salary salary
  of customer_details cr
  where (case when ' > ' = ' > ' then ' cr.salary > 5000')

  Another null
  (end);
  
  
  the expression in the when clause of the statement of the case, when comes from HQ and according to the choice I have to make the where clause.
  That is why, for the execution of the query, I put ' > ' in this place.
  
  If the original query will look like this (for reference):
  
  Select cr.customer_name. ' - ' || CR.customer_number as cust_name,
  CR. Salary salary
  of customer_details cr
  where (case when variable = ' > ' then ' cr.salary > 5000')

  When the variable = '=' and then 'cr.salary = 5000'
  Another null
  (end);
  
  
  so, in a real case, if the user selects ' > ' then the filter will be ' where cr.salary > 5000.
  If the user selects ' < ' then the filter will be ' where cr.salary < 5000.
  If the user selects '=', then the filter will be 'where cr.salary = 5000 '.
  
  but I get the error "ORA 00920:invalid relational operator.
  
  Help, please... Thanks in advance...

  Thank you all. Yes, the underside of the works.

  DELETE FROM TABLE1

  PS: Both COL1 and p_1 are string values. Would like to know how it works with out the quotes because it is a string.

  In addition I would like to follow the number of lines executed in each statement. Preference will have to use sql % rowcount. Are there other alternatives. Please let me know. Thanks in advance.

  Oracle 'knows' that the variable p_1 is a varchar2 data type and that col1 is a varchar2 data type, so he makes a comparison between them strinf. This is how variables work in any programming language that I am aware. The only time that you must provide a value is when you use a literal value (for example in an assignment variable, or as a parameter of a procedure).

  If you need to know the number of deleted rows, then sql % rowcount is the only sensible option. Just be aware that you need to get the value before committing yourself ot other options of SQL.

• Beginner: Get on the WHERE clause syntax error in SELECT

  I am very new to php and mySQL.  Use DW master/detail to generate Basic code I need.  One thing I have to do is to modify a select statement in the master to include a WHERE clause to limit the selection to a particular value in a field.

  I get a syntax error with the select statement in the WHERE clause, I add to the map.

  It's the part of the error message showing the location of the error:

  "WHERE group = 'Community' LIMIT 0, 10'"

  Php that generated the select is:

  $query_maps = "SELECT * FROM tblmaps ORDER BY tblmaps.» DispSeq ';

  $query_limit_maps = sprintf ("%s WHERE group =' LIMIT %s %d, %d", $query_maps, $selectGroup, $startRow_maps, $maxRows_maps);

  This approach to create the select statement is on the generated code for the master page.  He added the LIMIT clause.  I didn't add the ' WHERE group = '%s' and the variable $selectGroup, which comes from the old code.»  You can see that the $selectGroup variable is equal to the "community: group.»

  I scanned the web to see what syntax error, I could do, but haven't found anything that explains it.

  The resolved full select statement is:

  SELECT * FROM tblmaps ORDER BY tblmaps. WHERE DispSeq = 'Community' LIMIT 0,10 group

  What I don't see?

  Tom

  The group is a reserved word in MySQL. You could probably put single quotes around it, but I suggest to rename this column. Do not use reserved words for column names.

• Setting in the WHERE clause of the query

  Hi all
  
  I have 2 tables.
  
  TABLE_A contains 10 million documents.
  TABLE_B contains 100 records.
  
  I associate myself with these 2 tables
  
  Here's a.ID left

  SELECT A.*, B.*
  FROM TABLE_A a, TABLE_B b
  WHERE a.ID = b.ID;

  Here's b.ID left

  SELECT A.*, B.*
  FROM TABLE_A a, TABLE_B b
  WHERE b.ID = a.ID;

  My question is what query will give better performance? I thought that, if we put the column in the table with a lower number of lines on the left, then it will be faster than the other.

  In current versions of Oracle, it does not matter in what order you sum-up your predicates in the WHERE clause of a query: they will be optimized/executed in a way even.

• Execution of statement of UPDATE for the whole table even when the WHERE Clause is presentation

  Hi friends,
  
  I have a problem in a stored procedure where I wrote an update with a where clause clause statement. At some point only one line should be updated according to the unique identifier in where clause.
  
  But what is happening is that the Update statement is getting executed for all rows in the table to neglect the WHERE clause. I don't get any idea of why this is happening. Here is the stored procedure and the update statement is BOLD:-

  Thank you

  WHERE mdm_code = mdm_code

  This will always be value true - similar to WHERE 1 = 1.

  You typed it wrong or is the same as the variable column name? If they are the same test rename one of them.
