What is the size of VARCHAR2 in Oracle?
…
Oracle Built-In Datatypes.
| Built-In Datatype | Syntax |
|---|---|
| character_datatypes | { CHAR (size [ BYTE | CHAR ]) ] | VARCHAR2 (size [ BYTE | CHAR ]) | NCHAR [ (size) ] | NVARCHAR2 (size) } |
What is the difference between VARCHAR and VARCHAR2 in Oracle?
The main difference is that VARCHAR is ANSI Standard and VARCHAR2 is Oracle standard. The VarChar2 data type is used to store the character values. It is a variable-length data type i.e we can change the size of the character variable at execution time. Hence, it is also called a Dynamic datatype.
What is the difference between VARCHAR2 and NVARCHAR2 in Oracle?
VARCHAR2 vs. NVARCHAR2. First, the maximum size of VARCHAR2 can be in either bytes or characters, whereas the maximum size of NVARCHAR2 is only in characters. In addition, the maximum byte length of an NVARCHAR2 depends on the configured national character set.
What does VARCHAR2 mean in Oracle?
The VARCHAR2 datatype stores variable-length character strings. When you create a table with a VARCHAR2 column, you specify a maximum column length (in bytes, not characters) between 1 and 2000 for the VARCHAR2 column.
What is the maximum size of VARCHAR2 in Oracle 12c?
Since Oracle Database 12c, you can specify the maximum size of 32767 for the VARCHAR2 data type. Oracle uses the MAX_STRING_SIZE parameter for controlling the maximum size. If the MAX_STRING_SIZE is STANDARD , then the maximum size for VARCHAR2 is 4000 bytes.
What is the maximum size of VARCHAR2 in Oracle 11g?
The VARCHAR2 datatype represents variable-length character strings. On most platforms, the maximum length of a VARCHAR2 value is 65535 bytes.
How many characters can VARCHAR2 hold in Oracle?
VARCHAR2(15 BYTE) – the column can hold string of up to 15 bytes, VARCHAR2(15 CHAR) – the column can hold string of up to 15 characters, simply VARCHAR2(15) – the semantics depend on the value of the NLS_LENGTH_SEMANTICS parameter of the session creating the table. By default yout table is created with byte semantics.
What does VARCHAR2 20 byte mean?
VARCHAR2(20 BYTE) : Allows only the specified number of bytes to be stored in the column, regardless of how many characters this represents. VARCHAR2(20 CHAR) : Allows the specified number of characters to be stored in the column regardless of the number of bytes this equates to.
ORA-01460: unimplemented or unreasonable conversion requested
When I run the following .Net code:
using (var c = Shared.DataSources.BSS1.CreateCommand()) { c.CommandText = “\r
Select c1, c2, c3, rowid \r
From someSpecificTable \r
Where c3 = :p0”; var p = c.CreateParameter() as Oracle.DataAccess.Client.OracleParameter; c.Parameters.Add(p); p.OracleDbType = Oracle.DataAccess.Client.OracleDbType.Varchar2; p.DbType = System.Data.DbType.AnsiString; p.Size = 20; p.Value = “007”; p.ParameterName = “:p0”; using (var r = c.ExecuteReader()) { r.Read(); } }
I get the following error:
ORA-01460: unimplemented or unreasonable conversion requested ORA-02063: preceding line from XXX
This is not my database, and I don’t have control over the select statements that I get, that table IS from a database link.
The funny thing is that if I add the following code just before the ExecuteReader it runs fine.
c.CommandText = c.CommandText.Replace(“\r
“, ” “);
Unfortunately that is not a good solution in my case as I can’t control to SQL nore can I change it that way.
As for the table itself, the columns are: c1 Number(5) c2 varchar2(40) c3 varchar2(20).
I know that ORA-02063 that comes after indicate something about a database link, but I looked in the synonim table and it didn’t come from any database_link, and also I don’t think that \r
should affect database link.
I tried running the query without bound parameters, and it did work – but again bad practice to do so in a general term.
The trouble is that a competing tool that is not .Net based, is working and thus it’s not a general problem.
I also couldn’t reproduce the problem in my own environment, this is a customer database and site. I am using instant client 11.1.6.20 and also tested it with instant client 11.2.3.0
The db is 10 and the db link is to an oracle v8 database
Any help would be appreciated
ORA-01460: unimplemented or unreasonable conversion requested tips
ORA-01460: unimplemented or unreasonable conversion requested tips Oracle Error Tips by Donald Burleson
Question: I am working on advancing my SQL knowledge, so I write bits of code, run them and see what they do. Recently, I have run into an ORA-01460 error.
ORA-01460 unimplemented or unreasonable conversion requested
I have researched this mysterious ORA-01460 error, but I cannot see the cause of it in my simple SQL.
What causes the ORA-01460 and how can I avoid it?
Answer: First, use the oerr utility to look up information on the ORA-01460:
ORA-01460 unimplemented or unreasonable conversion requested
Cause: The requested format conversion is not supported. Action: Remove the requested conversion from the SQL statement. Check the syntax for the TO_CHAR, TO_DATE, and TO_NUMBER functions to see which conversions are supported.
Oracle MOSC documentation reveals that on Oracle versions 8.0.3 and higher, ORA-01460 can be associated with bug 2735156 which is caused by “‘mixing’ PLSQL and SQL”.
There are other reported causes of the ORA-01460 as well:
Incompatible character sets can cause an ORA-01460
Using SQL Developer, attempting to pass a string to a bind variable value in excess of 4000 bytes can result in an ORA-01460
With ODP, users moving from the 10.2 client and 10.2 ODP to the 11.1 client and 11.1.0.6.10 ODP reported an ORA-01460 error. This was a bug that should be fixed by patching ODP to the most recent version.
It appears, according to information on bug 5872943, that the ORA-01460 associated with ODP.NET, while not an ODP error, persisted through database version 11.2 where it has been reported as fixed.
ORA-01460: unimplemented or unreasonable conversion requested
I got ” ORA-01460: unimplemented or unreasonable conversion requested ” error in Oracle database.
ORA-01460: unimplemented or unreasonable conversion requested
Details of error are as follows.
ORA-01460 unimplemented or unreasonable conversion requested Cause: The requested format conversion is not supported. Action: Remove the requested conversion from the SQL statement. Check the syntax for the TO_CHAR, TO_DATE, and TO_NUMBER functions to see which conversions are supported.
unimplemented or unreasonable conversion requested
This ORA-01460 errors are related with the requested format conversion is not supported.
To solve this error, you need to remove the requested conversion from the SQL statement.
Check the syntax for the TO_CHAR, TO_DATE, and TO_NUMBER functions to see which conversions are supported.
Or Incompatible character sets between Oracle Server and Client can cause this error, so check and fix the character set of Client.

231 TIMESTAMP ( fractional_seconds_precision ) WITH LOCAL TIME ZONE All values of TIMESTAMP WITH TIME ZONE , with the following exceptions: Data is normalized to the database time zone when it is stored in the database.
When the data is retrieved, users see the data in the session time zone.
182 INTERVAL YEAR ( year_precision ) TO MONTH Stores a period of time in years and months, where year_precision is the number of digits in the YEAR datetime field. Accepted values are 0 to 9. The default is 2.
