Description:
ORA-01435 user does not exist
Cause:
This message is caused by any reference to a non-existent user. For example, it occurs if a SELECT, GRANT, or REVOKE statement specifies a username that does not exist. Only a GRANT CONNECT statement may specify a new username. All other GRANT and REVOKE statements must specify existing usernames. If specified in a SELECT statement, usernames must already exist.
Description:
ORA-01436 CONNECT BY loop in user data
Cause:
The condition specified in a CONNECT BY clause caused a loop in the query, where the next record to be selected is a descendent of itself. When this happens, there can be no end to the query.
Description:
ORA-01437 cannot have join with CONNECT BY
Cause:
A join operation was specified with a CONNECT BY clause. If a CONNECT BY clause is used in a SELECT statement for a tree-structured query, only one table may be referenced in the query.
Description:
ORA-01438 value larger than specified precision allows for this column
Cause:
When inserting or updating records, a numeric value was entered that exceeded the precision defined for the column.
Description:
ORA-01439 column to be modified must be empty to change datatype
Cause:
An ALTER TABLE MODIFY statement attempted to change the datatype of a column containing data. A column whose datatype is to be altered must contain only NULL values.
Description:
ORA-01440 column to be modified must be empty to decrease precision or scale
Cause:
An ALTER TABLE MODIFY statement attempted to decrease the scale or precision of a numeric column containing data. In order to decrease either of these values, the column must contain only NULL values. An attempt to increase the scale without also increasing the precision will also cause this message.
Description:
ORA-01441 cannot decrease column length because some value is too big
Cause:
An ALTER TABLE MODIFY statement attempted to decrease the size of a character field containing data. A column whose maximum size is to be decreased must contain only NULL values.
Description:
ORA-01442 column to be modified to NOT NULL is already NOT NULL
Cause:
An ALTER TABLE MODIFY statement attempted to change a column specification unnecessarily, from NOT NULL to NOT NULL.
Description:
ORA-01443 internal inconsistency; illegal datatype in resultant view column
Cause:
An internal error occurred in referencing a view.
Description:
ORA-01444 internal inconsistency; internal datatype maps to invalid external type
Cause:
This is an internal error message not normally issued.
