Recently, some readers have encountered the well-known Oracle SQL Error 1480 error code. This issue can occur for several reasons. Now let’s talk about some of them.

Oracle error 1480 is thrown when trying to scan a box through 02524 (Reject Box) or even through the sorter interface. Oracle error 1480 is displayed when trying to scan a mailbox before 02524 (forwarder) or to the sort interface.
The message_id is the actual error ID for the role change failover event, possibly 1480. For an integer Job_id, you have the option to create a SQL Server Agent job that will run when this warning occurs. Job_id is always the job_id for a SQL Server Agent job.

The NVARCHAR2 column can contain up to 1000 characters.
However, the actual data is up to the maximum byte 4000.
Both size limits must be respected at runtime.
Impact on character encoding and semantic characters with NVARCHAR2 memory
are the NCHAR, NVARCHAR2, and NCLOB Unicode data types. Dates in reserved columns of Unicode date types are clearly stored exclusively in their own Unicode encodings
regardless of the database character set.
This Unicode encoding is determined by the NLS_NCHAR_CHARACTERSET database property.
The maximum size of nvarchar2 is 4000 bytes, NLS_NCHAR_CHARACTERSET will be AL16UTF16 or AL32UTF8
– AL16UTF16 is a suitably long character set where each type is represented by 2 bytes.
– AL32UTF8 is a variable length character set, each character is represented by one to 4 bytes.
If NLS_NCHAR_CHARACTERSET can be set to AL32UTF8, you can enter the string with the largest number of bytes of 4000 bytes in From nvarchar2, OpenEdge UTF-8 client, i.e. h.
4000 protected single-byte characters

If NLS_NCHAR_CHARACTERSET is also AL16UTF16, you can add a string with the maximum possible 4000 bytes to From nvarchar2, that is, OpenEdge UTF-8 client. H. Collection of up to 2000 characters.
NLS_LENGTH_SEMANTICS doesn’t even apply Unicode to datatypes (NCHAR, NVARCHAR2, CLOB and NCLOB columns, which are usually always character-based), only CHAR and VARCHAR2 columns
Error Messages < br>
The data server is literally unaware of the benefits of NLS_NCHAR_CHARACTERSET and sets the maximum length of the NVARCHAR2 field to 4000 characters in fact A schematic diagram of a data server.
For a data server, the unit of measure must be number of characters, not number of bytes.
Therefore, an error is generated immediately after this by all data servers if the string is compared 4000 characters longer and the SQL statement is not generated:
The smile on this line, inserted or just updated, is too big (4212)
If the entire string matches the condition within <= 4000 characters, the SQL statement is also generated by the data server, but sent to the database.
Oracle DB Vehicle Engine estimates the size of all strings in bytes. If the string length is> four thousand bytes in the encoding specified by the NLS_NCHAR_CHARACTER parameter, the Oracle client interface tends to return the following error to the generic DataServer engine:
ORA-01480: trailing zero missing directly from STR binding
However, the actual information can be up to 4000 bytes.
NCHAR, NVARCHAR2, and NCLOB are Unicode data types. Stored data columns for Unicode date types can only be stored in their own Unicode encodings
The maximum size of nvarchar2 is 4000 bytes, as evidenced by NLS_NCHAR_CHARACTERSET AL16UTF16 or AL32UTF8
– AL16UTF16 are constant length character sets where each element is represented by 2 bytes. AL32UTF8
– will be variable length character sets, each character is represented by up to 4 bytes.
If NLS_NCHAR_CHARACTERSET is probably set to AL32UTF8, you can use a string up to 4000 bytes in From nvarchar2, OpenEdge UTF-8 client, i.e. h.
If NLS_NCHAR_CHARACTERSET is typically set to AL16UTF16, you can search for a string up to 4000 bytes, that is, a string up to 2000 characters, in From nvarchar2, an OpenEdge UTF-8 client.
Both restriction zones must be observed simultaneously with execution.
Influence of character encoding and semantics on NVARCHAR2 garage capacity
NLS_LENGTH_SEMANTICS does not use Unicode data types (NCHAR, NVARCHAR2, CLOB, and NCLOB contents, which are always character-based), but applies directly to CHAR and VARCHAR2 columns
The data server does not know the value of NLS_NCHAR_CHARACTERSET and sets the maximum field length for NVARCHAR2 to 4000 characters when using the data server schema.
For data servers, the unit is the number of hits, not the number of bytes.
Therefore, a new tracking error is generated by the data server if the string is indeed longer than 4000 characters and every SQL statement is not generated:
This positioned or updatable line contains (4212)
If the string matches the condition within <= 4000 characters, the SQL report is generated by you, the data server, and sent to the database database.
The Oracle engine estimates the size of a character string in bytes. If the character string is longer than four thousand bytes in the encoding specified by the NLS_NCHAR_CHARACTER parameter, the Oracle client interface will return the following error so you can invoke the DataServer engine:
