Yeah, if you know that basic rule, it's obvious why exactly those limitations were listed.
Coming from the limitations is a bit more difficult to understand the "why". This discussion thread is closed Start new discussion. Solution to the halting Problem? DB2 Database. Problem with virtual method. When the value of the foreign key is updated, the update value of a foreign key must be equal to the value of the primary key of some row of the parent table of the associated relationship.
The object table is unchanged. The value of a primary key in a parent row cannot be updated if the parent row has any dependent rows. Examine the primary key of the object table and the foreign key of the dependent table to determine if the value of the specified row of the primary key should be changed.
If this does not expose the problem, examine the contents of the object table and the dependent table to determine the cause of the problem. The contents of the object table are unchanged. Examine the search condition of the subselect to make sure that no more than one row of data is selected. Examine the search condition of the UPDATE statement to make sure that no more than one row of the object table is selected to be updated.
The statement violates the rule that no column name can appear more than once in any such list. Correct the statement to specify unique names for each column. Either the keys do not have the same number of columns or their descriptions are not identical.
The requirement for identical descriptions includes data type, length attribute, and field procedure. Correct the statement so that the description of the foreign key conforms to that of the primary key of the indicated table. The statement cannot be executed Correct the statement so that the table nominated as a parent in the FOREIGN KEY clause references a table with a primary key, or define a primary key for the table nominated as a parent. Its definition is incomplete, and it cannot be used until a unique index is defined for the primary key the primary index and for each set of columns in any UNIQUE clause the required unique indexes.
Define a primary index or a required unique index on the table before referencing it. The statement cannot be executed Correct the statement and rerun it.
The resulting row violated the check constraint definition on the table. The contents of the table are unchanged. The data must be changed to satisfy the check constraint. Authorization ID 'auth id' attempted to perform 'operation' on object 'object name' without having been granted the proper authority to do so.
Ensure that 'authorization ID' has been granted the authority to perform the desired operation, that the 'object name' exists, and that 'authorization ID' is not trying to create a table with a different authorization ID. Installation Action: Check for an attempted authorization violation. Ensure that the authorization ID has been granted the authority necessary to perform the desired operation.
No privileges were granted. No privileges were revoked. No 'privileges' were revoked from any authorization ID. Check the appropriate authorization catalog tables to verify that the revokee 'authid2' possesses the privilege to be revoked. As an aid to the programmer,'keyword list' provides a list of the keywords that would be permitted in this context. No privileges were granted or revoked. No new object was created, and the existing object was not altered or modified Either the existing object must be dropped or another name must be chosen for the new object.
The specified index was not created. The index definition must be modified to conform to the system imposed column limit of Examine the data to ascertain whether or not the duplicate data is valid. Alternatively, consider creating a nonunique index. Alternatively, the specification of data type may be incorrect or invalid. The specified table was not created or altered. Correct the syntax, and resubmit the statement. You cannot insert into or delete from a DB2 catalog table.
Do not attempt to insert into or delete from a catalog table. Column names must be unique within an index, a table, or a view. The specified index,table, or view was not created. The specified table cannot be created or altered. Change the table definition to keep within the prescribed limits. The maximum length permitted is a function of whether the index is partitioned or not, whether the index is unique or not, and the number of subpages of the index.
For a nonpartitioned index with less than 8 subpages either unique or not , the maximum permitted key length is The definition for the index must be modified possibly by eliminating one or more key columns to reduce the length of the key to the permitted maximum.
For example, a storage group cannot be dropped if there are one or more existing table spaces that use that storage group. Execution of the specified DROP statement would drop object 'obj name1' of type 'obj type1' on which object 'obj name2' of type 'obj type2' is dependent. The specified object was not dropped. Verify that the object specified in the DROP statement was indeed the object to be dropped.
If so, all the existing objects that have a dependency on that object must be dropped first. The attempted 'operation' cannot be performed on system data bases.
No changes were made to the specified system database. Do not attempt to perform the requested operation on system databases. Correct and resubmit the statement. An inconsistency exists between the DB2 catalog and directory. No new object was created, and the existing object was not altered or modified.
Notify the system programmer. A given table can have only one cluster index. Check to determine the identity and validity of the existing cluster index on the object table.
The statement cannot be run. A table cannot have more than one primary key. The table is not generally available until a new primary index is created. The definition of the table is marked as incomplete. Attempts to run already bound plans referencing the table will result in SQL or with resource unavailable reason code 00CF. The SQL statement cannot be executed.
Stop the pageset before resubmitting the statement. The SQL statement cannot be executed Verify that the correct table or partition is specified. The primary and secondary space allocation of a user managed data set cannot be altered by means of an ALTER statement. The statement cannot not be executed. Change a column of the key to allow null values or change the delete rule. Change the delete rule.
The specified cluster index was not created. Correct the statement to eliminate all but one specification for the keyword. Add column definition to the statement. Only one table may reside in a partitioned or default table space. The specified table was not created. Do not attempt to create more than one table in a partitioned or default table space. Table spaces and indexes index spaces can only be assigned or reassigned to buffer pools that are currently activated. The specified table space or index space was not created or altered.
If so, ensure that the buffer pool is activated before resubmitting the statement for execution. The contents of the object table were not modified. Determine the requirements imposed by the edit or validation procedure for inserts and updates of the object table.
Verify that the correct table was specified in the statement. If so, ensure that the partitioned index for the table has been created successfully before attempting to execute any SQL manipulative statements that reference that table.
If so, the definition for the partitioned table space must be examined so that a proper definition for the cluster index for the table may be constructed. The definition for the cluster index for a partitioned table must contain exactly as many PART specifications as there are partitions in the table space in which that table resides.
Also, the part numbers must be valid and unique. Verify that the proper object table was specified in the statement. Correct the statement so that each PART specification contains exactly the same number of limit key value specifications as there are columns in the index key. The specified index or table space was not altered. Determine whether the table space or index you want to alter is partitioned. If it is partitioned, specify a PART clause that identifies the partition you want to alter.
If it is not partitioned, do not specify the PART clause. In the message, 'stmt verb' is the type of data definition language DDL statement, 'object' is the DB2 object type, and 'function' is a utility, the governor, or the distributed data facility DDF.
If the object is part of the communications database, it cannot be dropped while the DDF is active The statement was not executed. If the function is a utility, wait for the function to complete or stop and then resubmit the statement for execution. If the function is the governor, the statement cannot be executed until the resource limit facility is stopped or switched to a different resource limit control table. If the function is the DDF, the facility must be stopped before the object can be dropped.
The specified index was not dropped. If a table has an edit procedure, no columns can be added to it. The specified table was not altered. Do not attempt to ALTER the definition of a table that has an installation written edit procedure associated with it. The specified table was not dropped. The table of a partitioned table space can only be dropped implicitly when the table space itself is dropped.
The page size of the table space is determined by the buffer pool used by that table space. The object table was not created or altered In the case of CREATE TABLE, either 1 the row length of the table must be reduced by eliminating or reducing the lengths of one or more of the columns , or 2 the table must be assigned to a table space that uses the 32K byte buffer pool assuming that the row length of the table does not exceed that page size limit.
In the case of ALTER TABLE, either 1 the length of the column to be added to the table must be reduced or, 2 if the row length of the table is already at the maximum, the table cannot be altered to add any additional columns.
In the case of a row length that exceeds the page size of a workfile table space, eliminate columns from the result of the join. The table space definition was not altered. If, however, it is assigned to buffer pool BP32K, the buffer pool assignment cannot be subsequently altered. Correct the statement to specify a 4K byte buffer pool. If this error should occur during interactive execution of an SQL statement or execution of an application program, installation administration should be notified.
Installation Action: It may be necessary to reexamine the buffer pool storage strategy. Limit key value specifications must conform to the data type of the corresponding index key column. In this case, the 'literal' must be of data type 'data type' to conform to the data type of column 'column name'. Correct the statement so that each limit key value literal is of precisely the same data type as that of the corresponding index key column.
The specified object was not created. Create separate tables as required to hold the additional information. The 'reason code' and 'message token' are defined by the field procedure. They may give additional information to help determine the cause of the problem.
Return code Error 4 Invalid value on encode or decode or invalid column description on define 8 Invalid parameter value 12 Field procedure error on any function Use 'reason code' and 'message token' for additional information. If it is not a field procedure error, determine the requirements imposed by the field procedure. If it is a field procedure error, examine the field procedure.
Then, in general, the application should terminate. This is invalid. Data subtypes can only be specified for character string columns; and field procedures can only be specified for string columns that allow nulls or have no default value. The data type code denotes a long string or has an invalid value.
