Objective Verify if it is true that insert records without PK/index plus create thme later is faster than insert with PK/Index. Note The point here is not about indexing takes more time (it is obvious), but the total cost (Insert without index + create index) is higher than (Insert with index). Because I was taught to insert without index and create index later as it should be faster. Environment Windows 7 64 bit on DELL Latitude core i7 2.8GHz 8G memory & SSD HDD Oracle 11G R2 64 bit Background I was taught that insert records without PK/Index and create them after insert would be faster than

This question is related to my original issue How to return an array from Java to PL/SQL ? , but is a more specific. I have been reading Oracle Database JDBC Developer's Guide and Creating ARRAY objects Server-Side Internal Driver oracle.jdbc.OracleConnection oracle.jdbc.OracleDriver but I still fail to write a minimum code where I can create ARRAY using ARRAY array = oracle.jdbc.OracleConnection.createARRAY(sql_type_name, elements); as instructed in Creating ARRAY objects .

I wanted to know if we have any technique by which we can calculate the value which needed to be set for a LIMIT clause of bulk collect operation. For example below, lets say our cursor has 10 Million records..What is the value which we can set for LIMIT clause to have optimum performance. Is there any way we can calculate it. decalre cursor c_emp is <some select query> var <variable> ; begin open c_emp; loop fetch c_emp bulk collect into var limit 2; exit when c_emp%NOTFOUND; end loop; close c_emp; end; Use an implicit cursor in a cursor FOR LOOP. It makes the code simpler and the default

Is there a way to pass column and table names dynamically to a query using bind variables? This could be done by using a simple concatenation operator || , but I would like a different approach by which this can be achieved. EDIT OPEN abc_cur FOR 'Select :column_name from :table_name' USING column_name,table_name; In this example I am passing column_name as empno,ename and table_name as emp But this approach is not working for me. Is it possible to have a different approach other that the traditional approach of concatenation? Table and column names cannot be passed as bind variables, no. The
