问题 I'm working with Oracle database 11g with PL/SQL. program is written in C#, .NET 4. I have a table with a varchar(4000) column, and I want to store in DB a text in Thai language. I found that when I try to store text in Thai that its length is longer than 1333 Oracle throws an exception, although the maximum length is 4000: ORA-01461: can bind a LONG value only for insert into a LONG column I also noticed that when I work with smaller limitation it works as expected. i.e.: varchar(10) -

问题 I'm using WebLogic 10.3.3 with Oracle 11g and face a weird problem with Spring Batch as soon as I'm switching from Spring ResourcelessTransactionManager (which is mainly for testing) to the productive DataSourceTransactionManager. First I used WebLogics default driver oracle.jdbc.xa.client.OracleXADataSource but this one fails because Spring can't set the isolation level - this is also documented here. I'm fine with that since I don't need global transactions anyway so I switched to oracle

问题 This question already has answers here : Search All Fields In All Tables For A Specific Value (Oracle) (15 answers) Closed 5 years ago . I need to search all tables in an oracle database for a specific string and return all the records where that string is found. I am working with SQL Developer. There are several really useful scripts and stored procedures that have been posted online that provide a way to search the entire database and they all seem to be able to return the table name and

问题 I have got a backupset of an Oracle 11g database which was created with RMAN. Now I want to import/restore the backupset onto a new and empty database server. I know that the command to create the backupset was run { backup as compressed backupset database tag "FULLBACKUP" format "/orabackup/rman/backup/FULL_%d_%T_%U"; backup as compressed backupset archivelog all tag "ARCHIVELOGS" format "/orabackup/rman/backup/ARCH_%d_%T_%U" delete all input; } but I cannot find out how to make the files

问题 I saw this link and this: If you specify a date value without a time component, then the default time is midnight. If you specify a date value without a date, then the default date is the first day of the current month. Oracle DATE columns always contain fields for both date and time. If your queries use a date format without a time portion, then you must ensure that the time fields in the DATE column are set to midnight. The solution is to put a constraint on column with the date data-type

问题 is there any way to write query with following functionality, add where clause as a conditional way, select e.emp_id, emp.admin_user from employees e if emp.admin != 'Y' then query run with where clause else query run without where clause ? 回答1: Using a CASE expression in the WHERE clause should do the trick. When you say you don't need the where clause if condition is not met, then all you want is a condition like WHERE 1 = 1 , i.e. when condition is not met then return all rows. So, you

问题 I need to search over a DB table using some kind of fuzzy search like the one from oracle and using indexes since I do not want a table scan(there is a lot of data). I want to ignore case, language special stuff(ñ, ß, ...) and special characters like _, (), -, etc... Search for "maria (cool)" should get "maria- COOL" and "María_Cool" as matches. Is that possible in Oracle in some way? About the case, I think it can be solved created the index directly in lower case and searching always lower
