Want to understand difference between Concat function and "||" operator. I am getting the same result for both. Below is the test case for your reference.
Select 'H '||' S' From Dual;
--Output H S
Select Concat('H ',' S') A From Dual;
--Output H S
Select Length('H '||' S') A From Dual;
--Output 6
Select Length(Concat('H ',' S')) A From Dual;
--Output 6

View 2 Replies View RelatedI know difference between procedure and function.if we want a return value from procedure, we can have OUT parameter. Similarly with function, in addition to returning a value from function, it can also send an OUT parameter value as a return value. That means, in one or the other way we are able to get a return value from both program units. Normally, I would fill a OUT variable with error message when an exception occurs. I use this varaible,after procedure call, to detect if an exception occurred or not. Similar task can be performed by a function, it returns a true/false and a value thru OUT variables.
both program units return values in the form of OUT parameters. Where exactly should we use a function, where exactly should we use a procedure?
difference between Procedure and Function.We Know that Procedure is Basically Used to perform Actions and Functions are Basically Used for Calculations but what would be the exact difference since Actions/Calculations can be done in both Procedure and Functions.Which factors decide whether we need to write a Procedure and in which cases we need Function.

From java point of view are there any guidelines when to prefer one over the other(betn stored procedure and function).
SELECT COUNT(*) FROM APP.Big_table; Number of record--222653402
This is a big table to get the it's taking 8 minutes time, so that I tried the following SQL to get the count quickly.
SELECT num_rows FROM all_tables WHERE table_NAME='BIG_TABLE'
and owner='APP'; --Number of records 237213998
But I got the different count for the two SQLs. Why there is a difference in the count. Which one is correct.
Explain with the best example for difference between translate and replace function.

OK I got three different Tables

As you see, I only need the Customer one time followed by part, amount and address - separated hyphen - comma, next part, amount, address and so on ...I've tried the PIVOT way and STRAGG (wm_concat) but all failed so far.The main problem is that when one customer fits more than one condition, ora throws: ORA-01427: single-row subquery returns more than one row

View 15 Replies View RelatedI'm trying to concatenate a local phone number field. The LDAP system only has the last 5 digits but for the directory database we need all 7 digits.I've tried every combination I can think of to get the concatenation to work but every combination results in just the first two digits being imported, e.g.,
LOCAL_NUM "'20'||:local_num",
results in just 20 being imported. Every iteration I've tried that didn't result in an error imported only the 20 and ignored the ||. I've also tried calling the CONCAT directly, e.g.,
LOCAL_NUM "CONCAT('20', :local_num)",
result is the same.The problem seems to be that the loader is ignoring the concatenate statement all together. I've tried the statements outside of the loader via sqlplus with expected result so I'm confused as to why it's not working within the loader.

Will the above query solve my purpose?
