oracle11g

问题 We have a table in Oracle 11g with a varchar2 column. We use a proprietary programming language where this column is defined as string. Maximum we can store 2000 characters (4000 bytes) in this column. Now the requirement is such that the column needs to store more than 2000 characters (in fact unlimited characters). The DBAs don't like BLOB or LONG datatypes for maintenance reasons. The solution that I can think of is to remove this column from the original table and have a separate table

问题 I'm writing a database accessor in Java. The database is in Oracle 11g, of which I am absolutely not familiar, and I have JDK 1.6. Will ojdbc4.jar do for my program? We're not allowed to connect to the Internet in the office and I can't download ojdbc6.jar, which I've read is more compatible with my setup. What strings should I put in the Class.forName(String driver) and DriverManager.getConnection(String connectionURL)? I don't know the driver string and the connection URL since they

问题 I want to insert Indian Rupee symbol in oracle 11g. I have tried: insert into currency(name, symbol) values ('rupee', unistr('\20B9')); but its not working. SELECT ascii('₹') FROM dual; it gives ascii value for Rupee symbol but after insert it shows box in the row. here you can see SELECT chr(14844601) FROM dual; 回答1: Seems that you just need to change a font in SQL Developer. Check this SQLFiddle. There are two things wrong in your question text: to get unicode symbol from it's code nchr()

问题 I'm OK with either a PL/SQL solution or an Access VBA/Excel VBA (though Access VBA is preferred over Excel VBA) one. so, PL/SQL is the first choice, Access VBA is second and Excel VBA is third. This is a very tough problem to explain. Please ask any questions and i will do my best to answer them clearly. I have the following dataset in a table called NR_PVO_120. How do i pick out a number (which can change but let's say, 6) of UNIQUE OtherIDs without excluding any OtherIDs under any fax

问题 I understand that Oracle supports multiple character sets, but how can determine if the current 11g system where I work has that functionality enabled? 回答1: SELECT * FROM v$nls_parameters WHERE parameter LIKE '%CHARACTERSET'; will show you the database and national character set. The database character set controls the encoding of data in CHAR and VARCHAR2 columns. If the database supports Unicode in those columns, the database character set should be AL32UTF8 (or UTF8 in some rare cases).

问题 I would like to use ORA_HASH on xmltype datatype, and workarounds are straight forward solutions ? I am using oracle 11g r2 and binary xml as storage option for xmltype column Query which I used for creation of the table is create table samplebinary ( indexid number(19,0) , xmlcolumn xmltype not null) xmltype column xmlcolumn store as binary xml; 回答1: As you already know, ora_hash doesn't accept long or LOB values. You could pass in the first 4k or 32k of the XML content, but if you need to
