问题 I tried to set the dbms_output size to unlimited inside a stored procedure. But it gave me compilation errors. So I tried in the SQL*Plus prompt the below way. But still I get the buffer overflow error. How can I overcome this? set serveroutput on size unlimited; exec service_update; ORA-20000: ORU-10027: buffer overflow, limit of 30000 bytes ORA-06512: at "SYS.DBMS_OUTPUT", line 32 ORA-06512: at "SYS.DBMS_OUTPUT", line 97 ORA-06512: at "SYS.DBMS_OUTPUT", line 112 ORA-06512: at "ARBOR.SERVICE

问题 In MySql, the concept of pagination can easily be implemented with a single SQL statement using the LIMIT clause something like the following. SELECT country_id, country_name FROM country c ORDER BY country_id DESC LIMIT 4, 5; It would retrieve the rows starting from 5 to 10 in the result set which the SQL query retrieves. In Oracle, the same thing can be achieved using row numbers with a subquery making the task somewhat tedious as follows. SELECT country_id, country_name FROM (SELECT rownum

问题 In MS-SQL we can have the following constraint during table creation create table test ( WarningEnabled bit NOT NULL CONSTRAINT DF_WarningEnabled DEFAULT 1, ); as we can see, i have given a name for Default constraint. IS it possible to do this in oracle 回答1: No. Oracle does not implement a default value as a constraint so there is no way to name the constraint. You also won't be able to see the default constraint in the data dictionary views that relate to constraints (i.e. ALL_CONSTRAINTS ,

问题 I have 2 Oracle databases and I frequently copy data from prod DB to test DB using TOAD, by generating insert scripts for Prod DB and running it on the test DB later. I am trying to do it faster through a batch file. I think that I can use this solution but the DB has an auto-increment column. If I use this solution, would that column be affected? Do I need to change the script in some way? I haven't tried this so far as I have no access do the DB and would be able to test this only on Monday

问题 I'm having troubles at implementing and ASP .Net Application in IIS 6 Server. When the user tries to open a web page that access the database, iis server throws "Attempted to read or write protected memory" this is the StackTrace: System.AccessViolationException: Attempted to read or write protected memory.

问题 I have an Oracle DB package that is routinely causing what I believe is an ITL (Interested Transaction List) deadlock. The relevant portion of a trace file is below.

问题 I want to run 200+ select queries and append the results to a file. All queries are the same the only difference in the date-time variable. I don't have privileges to create a routine that's why I had to create all the queries. I don't have privileges to create a view or another table to store the results in. I don't have access to PL/SQL. Now I need to create a report with the results of each one of this queries (all results are integer numbers) but I don't seem to find another solution but

问题 I have a class representing a table on database that is defined: public class MyClass{ public int MyClassId{get;set;} public string Name{get;set;} public string LastNamw{get;set;} public DateTime From{get;set;} public DateTime To{get;set;} } On which I want to run some search query against oracle database. Now the question is : var list = context.MyClass .Where(x => x.From>= FromMyDate) .Where(x => x.To <= ToMyDate); var list = context.MyClass .Where(x => x.From>= FromMyDate && x.To <=

问题 I have an account, password and the URL. 回答1: Use: Connection connection = null; try { // Load the JDBC driver String driverName = "oracle.jdbc.driver.OracleDriver"; Class.forName(driverName); // Create a connection to the database String serverName = "127.0.0.1"; String portNumber = "1521"; String sid = "mydatabase"; String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid; String username = "username"; String password = "password"; connection = DriverManager

问题 Oracle server is not so smart to catch updated packages. so whenever I recompile my package. it throws existing package invalidate error. if is there any way so that I can refresh only my package on server. So I don't need to bounce server and stop server which is used by everyone. 回答1: Minimize public functions, procedures, and variables. Invalid objects and ORA-04068: existing state of packages has been discarded errors will decrease after minimizing public objects and minimizing the
