Q. I ran the
sample code and the output tables were not created in my user schema.
What now?
A. The stored procedures
can fail if one or more of the following conditions are true:
-
The request specifies an output
location to which the user does not have Write permission. Verify
that you have access to the database that is specified in the output_table parameters.
-
The data quality stored procedures
are not installed correctly. Verify that the stored procedures are
in the SAS_SYSFNLIB database by executing the following command in
BTEQ:
select TableName from dbc.tables where databasename='SAS_SYSFNLIB'
and tablename like 'dq_%';
The command should
return a list similar to the following list (This is not a complete
list.):
TableName
------------------------------
dq_set_qkb
dq_match_parsed
dqi_drop_view_if_exists
dqi_get_option_default
dq_debug
dq_propercase
dqi_tbl_dbname
dqi_drop_tbl_if_exists
dq_set_option
dqt_error
dq_standardize
dq_standardize_parsed
dq_debug2
dqi_invoke_table
dq_lowercase
dq_set_locale
dq_extract
dq_uppercase
dq_list_bindings
dqi_replace_tags
dq_list_defns
dqi_call_ep
dqi_get_bool_option
dqi_gen_toktxt
dqt_codegen
dq_match
dq_parse
dqt_trace
dq_pattern
dqi_clear_tok_tbls
dqt_tokname_tmp
dq_format
dq_list_locales
dqi_invoke_scalar
dqi_invoke_preparsed
dq_bind_token
dq_gender
If the procedures are
absent, run the dq_install.sh script again, making sure that you are
logged in as Teradata system administrator.
-
Permission to the data quality
stored procedures is not granted correctly. Verify that the target
user name submitted to the dq_grant.sh script is a valid user account
in the Teradata database. Verify that the database server and granter
information in the dq_grant.sh shell script is correct.
-
The QKB is not in the correct location.
Look for subdirectories similar to the following in the /opt/qkb/default directory
on the Teradata nodes: chopinfo, grammar, locale, phonetx, regexlib, scheme,
and vocab.
-
Your SQL request does not use the
Teradata dialect. The stored procedures are invoked with the CALL
keyword from any product that supports the Teradata SQL dialect. When
you submit the data quality stored procedures in the SAS SQL procedure
using explicit pass-through, the database connection is made in ANSI
mode by default. You must specify the MODE= option to switch to Teradata
mode. Consult the SAS/ACCESS Interface to Teradata documentation for
more information about the MODE= option. Consult appropriate documentation
for how to set Teradata mode in other client programs.
