Oracle Details:- Oracle 10g Enterprise Edition Host running XP x32 I use scott tiger for logging with SQL* Plus . I dont provide any HOST STRING . How can i setup Oracle to accept Host String ? i am asking this because i guess the problem is related to this IP : 192.168.17.132 , Hostname : vmxp1 tnsnames.ora file:- GLOBALDB = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = vmxp1)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = globaldb) ) ) EXTPROC_CONNECTION_DATA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC)) ) (CONNECT_DATA = (SID =

We have 2 very simple SELECT statements: SELECT value from table where date between DATE1 and DATE2 SELECT value from table where date between DATE3 and DATE4 We need a way to write a single SQL statement which will get the difference of the "value" that is returned from these two SQL statements. We tried the following but it was not successful: SELECT value from table where date between DATE1 and DATE2 minus SELECT value from table where date between DATE3 and DATE4 Any suggestion is highly appreciated. Untested but should work: SELECT (SELECT value from table where date between DATE1 and

I am attempting to get Oracle sqlplus (10.2) to spool out Unicode data on a Linux machine. I have found several discussions of this issue, but no clear answers, other than to check locale settings and set NLS_LANG to AL32UTF8. All locale info is set to "en_US.UTF-8", I'll post the full output upon request. The OS (vi, etc.), will recognize and accept Unicode characters without issue. However, when using sqlplus, all non-ASCII characters are changed to ? characters. The Oracle DB has NLS_CHARACTERSET set to AL32UTF8, and NLS_NCHAR_CHARACTERSET set to AL16UTF16. Am I missing some setting or

Rephrased, given I use date like so: date'2010-04-10' , could the outcome be anything but April 10th 2010 (e.g. October 4th 2010)? UPDATE I hear what you, and the docs, say. But... When a batch job runs, with hard-coded date'yyyy-mm-dd':s, it fails for some (non-deterministic) calculations. Running the failing SQL statements in PL/SQL Developer never yields the same, incorrect, value. First, I ran the same calculations (hundreds of thousands) with the date'' date literals replaced with the to_date('', '') function, and everything worked just fine. Then, I used NHibernate and its LINQ provider,

If I used the following expression, the result should be 1. regexp_instr('500 Oracle Parkway, Redwood Shores, CA','[[:digit:]]') Is there a way to make this look for the last number in the string? If I were to look for the last number in the above example, it should return 3. If you were using 11g, you could use regexp_count to determine the number of times that a pattern exists in the string and feed that into the regexp_instr regexp_instr( str, '[[:digit:]]', 1, regexp_count( str, '[[:digit:]]') ) Since you're on 10g, however, the simplest option is probably to reverse the string and

I have some code: @Id @SequenceGenerator(name = "SOMETHING_SEQ") @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SOMETHING_SEQ") @Column(name = "SOMETHING", nullable = false) private Long id; How is hibernate providing my id? I see in my database there a single sequence named 'hibernate_sequence' and no other hibernate 'special tables'. Actually, here your SOMETHING_SEQ is the name of sequence you configured somewhere in your hibernate config. And hibernate_sequence is the sequence name in the database. In configuration it would be looking something like below, <sequence

for example i have this table: itemgroup | description | price A, a, 10 A, b, 12 A, c, 14 B, g, 11 B, h, 16 now i want to select the rows with the highest price in one group like this: A, c, 14 B, h, 16 The SQL query (is fully functional) wich gets me near this is: SELECT itemgroup, MAX( price ) FROM table GROUP BY itemgroup A, 14 B, 16 By trying this I get an "not a GROUP BY expression"-error: SELECT itemgroup, description, MAX( price ) FROM table GROUP BY itemgroup I need something like this pseudo query: SELECT itemgroup, IGNORE( description), MAX( price ) FROM table GROUP BY itemgroup I

SELECT col1 'COLUMN 1' FROM TABLENAME I am getting an error 'from keyword not found where expected' How can you give column alias in Oracle 10g some examples are appreciated Shepherdess Use double quotes: SELECT col1 "COLUMN 1" FROM TABLENAME Shepherdess is correct - you can't use single quotes here. If the alias doesn't have spaces, you could just type the name without any quotes: SELECT col1 column1 FROM TABLENAME Single quotes is not allowed here .Either you have to use double quotes or not quots between column1.Careful about column1 because it doesn't supported any spaces between column1.

I want to store a short array of 64 bytes in Oracle database (a password hash). I thought char(64 byte) is what I need, but it seems like it doesn't work. In Microsoft SQL, I use binary and varbinary types. What type do I need to use in Oracle? Every example I've found uses blob to store binary data, but I suppose blob is intended only for large objects, not for fixed size short arrays. When updating the data, is the code like this appropriate: byte[] passwordHash = GenerateHash(); using (OracleCommand updateHash = new OracleCommand("update A set passwordHash = :hash where EntryId = :id",
