Db2 Error Code 805
a null indicator. In DB2, a NULL is stored using a special one-byte null indicator which is attached to every NULLABLE column. If the column is defined as NULL, then the indicator field is used to record http://www.ibm.com/support/knowledgecenter/SSEPEK_11.0.0/codes/src/tpc/n305.html this. The indicator variable is transparent to an end user, but must be provided for when programming in a host language. A positive value or a value of 0 means the column is not null and any actual value stored in the column is valid. A negative value indicates that the column is set to null. If the value is -2 then the column was set to null as the result of a data http://www.allinterview.com/showanswers/13618/resolve-305-error-code-db2-and-also-please-let-know-codes.html conversion error. The default is null. There are two reasons for getting -305. 1) As said in the first answer if the table column is defined as NOT NULL (with no default) and if we try to insert a null value we get that. - This should be resolved by making sure the inserted value is not null. Null indicator cannot be used here since the column is defined as NOT NULL. 2) A table column is defined as NULL: The host variable has a not null value. The Null indicator is not set in the host program, so the null indicator is defaulted to a negative value. - This should be resolved by using a null indicator in the host program and moving the relevant value to the null indicator. Is This Answer Correct ? 53 Yes 5 No Answer / guest supose, one of ur DB2 table column is defined as NOT NULL, if u trying to insert null value on that column at that time , u will get this error. u can slove this error by handling the null indicator in ur program. define null indiactor workign stroage variable with s9(4) comp. Is This Answer Correct ? 44 Yes 12 No Answer / s If a column contains nulls and you dont include a
In DB2, the columns defined as NULL needs to be handled carefully else it will throw null exception error, in order to over come this error data type can be handled by using null indicator. NULL is stored using a special one-byte http://mainframestutor.in/305-db2-null-indicator/ null indicator that is "attached" to every nullable column. If the column is set to https://en.wikipedia.org/wiki/DB2_SQL_return_codes NULL, then the indicator field is used to record this. Using NULL will never save space in a DB2 database design - in fact, it will always add an extra byte for every column that can be NULL. The byte is used whether or not the column is actually set to NULL. The indicator variable is transparent to an db2 error end user Consider below Table : Create Table SAMP_TAB SN CHAR (10) SNAME CHAR (10) STATUS CHAR (2) NOT NULL BY DEFAULT CITY CHAR (10) NOT NULL Note :: Unless you specify NOT NULL, the default is to allow for NULL In above table SN and SNAME columns holds null values by default, in order to handle these null variables we need to have NULL-INDICATORS declares in the Program as S9(4) comp variable (A indicator variable is db2 error code shared by both the database manager and the host application. Therefore, this variable must be declared in the application as a host variable, which corresponds to the SQL data type SMALLINT) Let us declare the Null indicators for above two variables in application program as 02 SNAME-INDNULL S9(4) comp 05 SN-IN S9(4) comp What values Null indicators will hold : ‘-1’ : Field is having NULL value ‘ 0’ : Field is Not NULL value ‘-2’ : Field value is truncated How /Why to handling Null Values: When processing INSERT or UPDATE… statements, the database manager checks the null-indicator variable, if one exists. If the indicator variable is negative, the database manager sets the target column value to null, if nulls are allowed else it throws sql error code -305, we need null indicators to handle this situation. If the null-indicator variable is zero or positive, the database manager uses the value of the associated host variable. There are two reasons for getting -305 and Resolution : 1) If the table column is defined as NOT NULL (with no default) and if we try to insert a null value we get this error. Resoulution :This should be resolved by making sure that the inserted value is not null. Null indicator cannot be used here since the column is defined as NOT NULL. (validate the data, if its not nu
feature of DB2 programs is the error processing. The error diagnostic containing the SQL Return Code is held in the field SQLCODE within the DB2 SQLCA block. SQLCODE is no longer part of the SQL-standard. The SQL-standard replaced SQLCODE by the more detailed SQLSTATE. Contents 1 SQLCA 2 SQLCODE 2.1 Zero (Successful) 2.2 Negative values (Errors) 2.3 Positive Values (Warnings) 3 References SQLCA[edit] The SQL communications area (SQLCA) structure is used within the DB2 program to return error information to the application program. This information in the SQLCA and the SQLCODE field is updated after every API call for the SQL statement... SQLCA contains ERROR HANDLING data SQLCODE[edit] The SQLCODE field contains the SQL return code. The code can be zero (0), negative or positive. 0 means successful execution. Negative means unsuccessful with an error. An example is -911 which means a timeout has occurred with a rollback. Positive means successful execution with a warning. An example is +100 which means no rows found or end of table Here is a more comprehensive list of the SQLCODEs for DB2: Zero (Successful)[edit] 0 Successful Negative values (Errors)[edit] -007 The specified 'character' is not a valid character in SQL statements. -010 THE string constant beginning with string is not terminated properly. -029 INTO Clause required. -060 INVALID type SPECIFICATION: spec -084 Unacceptable SQL statement. -101 The statement is too long or too complex. -102 String constant is too long. -104 Illegal symbol encountered in the SQL statement. -117 The number of values in the INSERT does not match the number of columns. -122 Column or Expression in the Select List is not valid -180 Bad data in Date/Time/Timestamp. -181 Bad data in Date/Time/Timestamp. -188 The host variable in a DESCRIBE statement is not
