The function returns the extended information about the last
error.
Declaration
INT %GetLastExtErrorCode()
Description
Extended information about an error is adjusted by all
the actions for work with the database (DB_*, PG_*,
SQL_*, DBS_* + actions to control database transactions). Numerical value
of an error is gained directly from the database engine, therefore this
value depends on its type.
The implementation of database ESL action by D2000 DBManager
can be aborted before calling the database engine due to detection of error.
These errors are generated by D2000 DBManager and not by the database engine.
Internal errors, generated by D2000 DBManager, are basically negative:
Code
Msg
-70 001
<operation>: Column [row # <row_list>] in table <table_name> cannot be NULL! User defined constraint on D2000 table object was violated.
-70 002
<operation>: table <table_name>, column <column_name>, data length
<data_length>, column size in DB <column_size>, aborting operation.
-70 003
<operation>: table <table_name>, multirow update without keys, aborting operation.
-70 004
<operation>: table <table_name>, no columns to update in database, aborting operation.
-70 005
<operation>: use keys and <row_index>, row affected no rows in the table, aborting operation.
-70 101
Error when working with a file (DB_*_BLOB scrip actions).
-70 102
Error will be used when a return code of script action is _ERR_NO_DATA (PG_READ
or DB_UPDATE_BLOB).
or the error codes for DBManager, which are listed in
the table _ERR_NR_TRANS_EX
with reverse sign "-". For example, for
TOO_MANY_ROWS_IN_SELECT
the value, returned by the function, will be
-48. Or, for DBM_DATABASE_OFF,
the value will be -52.
