What is the SQLERRM error message?
It is different from the ORA codes, which you may also get when working with Oracle databases. The SQLERRM function returns the error message that relates to the error number provided. This function is similar to the SQLCODE function, where the only real useful place for it is inside an exception handler in PL/SQL.
What is the SQLCODE function?
The SQLCODE function returns the number code of the most recent exception. This number code is an ANSI-standard code, which means it is the same for all relational databases. It is different from the ORA codes, which you may also get when working with Oracle databases.
What is the SQLERRM length?
What Is The SQLERRM Length? The maximum length of the SQLERRM function return value is 512 characters. This is useful if you want to store the value in a table when you log an error.
What is the use of Sqlerrm?
The function SQLERRM returns the error message associated with its error-number argument. If the argument is omitted, it returns the error message associated with the current value of SQLCODE . SQLERRM with no argument is useful only in an exception handler.
What is SQLCODE in Plsql?
The function SQLCODE returns the number code of the most recent exception. For internal exceptions, SQLCODE returns the number of the associated Oracle error. The number that SQLCODE returns is negative unless the Oracle error is no data found, in which case SQLCODE returns +100 .
What is Sqlerrm in db2?
This SQLERRM scalar function takes a message identifier, locale and token input and returns the short or long message in the specified locale. If the input locale is not supported by the server, the message is returned in English.
What is the datatype of SQLCODE?
SQLCODE is a database state function that returns an INTEGER data type with a default value of 0 (zero).
What does SQLCODE 1 mean?
For user-defined exceptions, SQLCODE returns +1 , or a value you assign if the exception is associated with an Oracle error number through pragma EXCEPTION_INIT . Syntax. Description of the illustration sqlcode_function.gif. Usage Notes. SQLCODE is only useful in an exception handler.
What is the maximum length of Sqlerrm in Oracle?
512 bytesSQLERRM returns a maximum of 512 bytes, which is the maximum length of an Oracle Database error message (including the error code, nested messages, and message inserts, such as table and column names).
What is Sqlca in Db2?
A program that contains executable SQL statements and is precompiled with option LANGLEVEL SAA1 (the default) or MIA must provide exactly one SQLCA, though more than one SQLCA is possible by having one SQLCA per thread in a multi-threaded application.
What is Sqlstate?
SQLSTATE is a code which identifies SQL error conditions. It composed by five characters, which can be numbers or uppercase ASCII letters. An SQLSTATE value consists of a class (first two characters) and a subclass (last three characters).
What is embedded SQL in mainframe?
Embedded SQL statements are used in COBOL programs to perform standard SQL operations. Embedded SQL statements are preprocessed by the SQL processor before the application program is compiled. COBOL is known as the Host Language. COBOL-DB2 applications are those applications that include both COBOL and DB2.
What SQLCODE 100?
If SQLCODE = 100, "no data" was found. For example, a FETCH statement returned no data because the cursor was positioned after the last row of the result table. If SQLCODE > 0 and not = 100, execution was successful with a warning. If SQLCODE < 0, execution was not successful.
What is ref cursor in Oracle?
A REF CURSOR is a PL/SQL data type whose value is the memory address of a query work area on the database. In essence, a REF CURSOR is a pointer or a handle to a result set on the database. REF CURSOR s are represented through the OracleRefCursor ODP.NET class.
What is Pragma Exception_init in Oracle?
The pragma EXCEPTION_INIT associates an exception name with an Oracle error number. You can intercept any ORA- error and write a specific handler for it instead of using the OTHERS handler.
What does SQLERRM return?
If the argument is omitted, it returns the error message associated with the current value of SQLCODE. SQLERRM with no argument is useful only in an exception handler. Outside a handler, SQLERRM with no argument always returns the normal, successful completion message. For internal exceptions, SQLERRM returns the message associated with the Oracle error that occurred. The message begins with the Oracle error code.
Can you use SQLERRM in SQL?
You cannot use SQLERRM directly in a SQL statement. Assign the value of SQLERRM to a local variable first, as shown in Example 13-6. When using pragma RESTRICT_REFERENCES to assert the purity of a stored function, you cannot specify the constraints WNPS and RNPS if the function calls SQLERRM.
What does the SQLERRM Function do?
The SQLERRM function returns the error message associated with the most recently raised error exception. This function should only be used within the Exception Handling section of your code.
Example
Since EXCEPTION HANDLING is usually written with the following syntax:
