• Can I omit THEN in a when then the clause of an insert statement multi-table?

  Example of a test of the demo:

  You have been appointed as the DBA for a National Bank that provides services of credit and debit cards to its customers. The records for these two types of card users are stored and preserved in the card_customers of Bank data table.
  
  You decide to create separate tables for credit card users and users of debit cards and then use the data in the card_customers table to populate the new tables. Information for clients who hold both types of card must be added to the time of the tables.
  
  Which of the two following options provide the most effective way of inserting the customer data in the credit_card_holders and debit_card_holders tables? (Choose two.)
  

  INSERT INTO credit_card_holders SELECT * FROM card_customers WHERE card_type = "Credit"; INSERT INTO debit_card_holders SELECT * FROM card_customers WHERE card_type = "flow";

  INSERT ALL IN credit_card_holders IN debit_card_holders SELECT * FROM card_customers;

  INSERT ALL WHEN card_type = 'Crédit' IN credit_card_holders WHEN card_type = 'Throughput' IN debit_card_holders SELECT * FROM card_customers;

  INSERT FIRST WHEN card_type = 'Crédit' IN credit_card_holders WHEN card_type = 'Throughput' IN debit_card_holders SELECT * FROM card_customers;

  Explanation:

  In this scenario, the following statement provides the most effective way of inserting data in the credit_card_holders and debit_card_holders tables:
  
  INSERT ALL
  When card_type = 'Crédit' THEN credit_card_holders
  When card_type = 'Throughput' THEN debit_card_holders
  SELECT * FROM card_customers;
  
  Le INSERT all THE statement verifies the conditions in the two clauses WHEN , regardless whether one of them is true or false. If a condition when is true, then the line corresponding to the INSERT statement is executed is inserted in the card_customers in the credit_card_holders table or the debit_card_holders table. If a customer has a credit card and a debit card, there will be two rows in the table card_customers for the same customer, one with card_type = 'Crédit' and the other with card_type = 'Throughput'. This statement inserts the correct lines in the tables in a single pass.

• By comparing the number of different records of different tables of databases with Production DB

  Hello

  I updated 6 paintings of DEVEOPMENT and QA database production databases.

  According to the request of the customer, I want to create a stored procedure to compare the number of tables with the number of Production DB records.

  Could you please suggest me a better way to do this.

  example: select count (*) in the emoployee@Devlopment_Database.  -I want to check with select count (*) from employee@Procuction_Database

  Select count (*) in the emoployee@QA_Database.                 -I want to check with select count (*) from employee@Procuction_Database

  If so, your question is asking how to create a database link?

• Comparison of the data of several rows in a table - based on the primary key

  Currently I have a select statement that returns hundreds of records.  Each returned record is linked to A NUMBER of ORDER this order number has a recipe.  (a bit like a cooking recipe).  Each recipe has many records in the database related to this order number and records should be compared to records in a table that bind to a specific primary key...  (I have already developed the logic to isolate what PK I need).  If all these records that are returned by the select statement below does not match all the records containing PK in the table below, I need to get the next PK and compare all these recordings for select statements return.

  See below for a better understanding. Need a good example detailed on how to solve my problem here.

  Just to help you understand:

  Each element of the recipe is 3 parts (side, ref_des, part_number).  1 single recipe can have several parts (where the part_number), and each of these pieces should be placed on the lower side or top of the Board that is there "side" comes into play.  Same thing with Ref_Des.

  What is going on

  Select statement returns the RECIPE of ORDER NUMBER A.  There will be multiple records returned by this query.

  Select the Return statement:

  • Side
  • Ref_Des
  • Part_Number

  Example of return:

  B c17 75145-2

  T f14 89242-8

  B s12 45123-3

  etc,

  In general - what I need to do:

  There is a table called AUTO_RECIPE_DETAILS.  I take all of the records returned by the select query above and compare for each record in this table relating to the recipe 30319-000001.  30319-000001 a number of records.  It is the primary key for a whole recipe as seen above.  This primary key is bound the number of data records in this table.  The comparison is to see if all records under RECIPE_NAME 30319 -000001 match all the records returned by the select statement.

  IF IT DOES NOT MATCH: recover the following recipe in this table below 30319 -000002 and make the same comparison.
  

  Here's a perfect example of what the table looks like: (AUTO_RECIPE_DETAILS)

  
  

  RECIPE_NAME SIDE REF_DES PART_NUM

  -30319-000001 C16 87595-1 B

  -30319-000002           T B14 74150-4

  -30319-000001 T B14 34251-2          

  -30319-000001            T F24 84180-7

  -30319-000002 T B12 13710-8

• Can I get the total number of records that meet the conditions of a query using the Table API?

  Hello

  A < row > TableIterator is returned when I ask operations using the index of tables. If I want to get the total number of records, I count one by one using the returned TableIterator < row >.

  
  

  Can I get the total number of records directly meets the conditions of the query?

  I can get the total number of records directly the request of the meeting of the conditions of CLI using the command Global table - name tableName - count - index index-name-field fieldName - start startValue-end endValue.

  Can I get the same results using the Table API?

  I used MongoDB and NoSQL Oracle for about a year. According to the experience of the use of these dbs, I think mongoDB querying interface is powerful. In the contras, the query interface is relatively simple, which results is a lot of work that is usually a long time in the client side.

  Hello

  Counting records in a database is a tricky thing.  Any system that gives you an accurate count of the records will have a hotspot of concurrency on updates, namely the place where the counting is maintained.  Such a count is a problem of performance in addition to competitive access problem.   The problem is even more difficult in a system widely distributed such a NoSQL database.

  The CLI has overall command that counts, but does so by brutal force - iterate keys that correspond to the parameters of the operation.  This is how you must do this within the API.  There is not a lot of code, but you have to write.  You certainly want to use TableIterator TableAPI.tableKeysIterator (), because a key iteration is significantly faster than the iteration of lines.  Just one iteration and count.

  If you use TableAPI.multiGet () and a key with a touch of brightness full then, in fact, count the results as they are returned in a single piece (a list).

• Nested set tables in select query "in the clause of" take long time

  -I had the question, query "SELECT COLUMN_VALUE FROM TABLE (v_circuitid)" that is used in code above is responsible for this.

  -Same code works fine in development and Test environments, but prod it continues to work on

  -I solved this problem by creating a temporary table, loading of all values in the collection in the temporary table and using this temporary table "in the clause" "

  -Can answer why his behavior like this when I use the collection where clause?

  -I use Oracle 9i

  Here is a summary of the question and the solution for this.

  -Nested type to collect multiple values

  CREATE or REPLACE the TYPE t_circuitid IS TABLE OF VARCHAR2 (100);

  Below the code will simply on the run.

  DECLARE
  v_circuitid t_circuitid;
  v_count NUMBER;
  BEGIN
  SELECT nal_name
  LOOSE COLLECTION v_circuitid
  OF fs_head
  WHERE groupid = 10;

  SELECT COUNT (1)
  IN v_count
  OF fs_attrib
  WHERE NAME IN (SELECT COLUMN_VALUE
  TABLE (v_circuitid));

  Dbms_output.put_line (v_count);
  END;
  /

  Cause:-SELECT COLUMN_VALUE TABLE (v_circuitid)); -This request is causing problem

  Why?  : - Because the CBO does not know how many lines is present in the collection, by default it takes 8168 lines

  Note:-always happens, it depends on the volume of data in the table, the path chosen by CBO. In my case, the table is huge on prod compared to DEV so he was causing a problem.

  -The following modified code works very well

  DECLARE
  v_circuitid t_circuitid;
  v_count NUMBER;
  BEGIN
  SELECT nal_name
  LOOSE COLLECTION v_circuitid
  OF fs_head
  WHERE groupid = 10;

  SELECT COUNT (1)

  WHERE NAME IN (SELECT / * + cardinality (20 t) * /)
  COLUMN_VALUE
  TABLE (v_circuitid) t);

  Dbms_output.put_line (v_count);
  END;
  /

  Solution:-used as cardinality hint below.

  SELECT / * + cardinality (20 t) * / t COLUMN_VALUE TABLE (v_circuitid);

  Using cadinality I am saying CBO which dataset contains 20 lines or less.

  If it is version of Oracle 10 g and more, we can use below code (CARD utility).

  SELECT COLUMN_VALUE TABLE (CARD ((v_circuitid))
