I have a list of fields:
###FIELD_DOMAIN_ENG_VW +-------------+------------+-------------+ | TABLE_NAME | FIELD_NAME | DOMAIN_NAME | +-------------+------------+-------------+ | ENG.TABLE_1 | FIELD_1 | DOMAIN_ABC | | ENG.TABLE_1 | FIELD_2 | DOMAIN_XYZ | | ENG.TABLE_2 | FIELD_1 | DOMAIN_XYZ | +-------------+------------+-------------+
The view looks at all the tables in a geodatabase, and lists any fields that have a domain associated with them (a domain is the GIS equivalent of a lookup table/validation table).
The data tables look like this:
###TABLE_1 +--------------+--------------+ | FIELD_1 | FIELD_2 | | {DOMAIN_ABC} | {DOMAIN_XYZ} | +--------------+--------------+ | A | X | | B | Y | | C | zzzz | | BLACK SHEEP | | +--------------+--------------+
###TABLE_2 +--------------+--------------+ | FIELD_1 | FIELD_2 | | {DOMAIN_XYZ} | | +--------------+--------------+ | Z | ... | | Y | | | X | | | asdf | | +--------------+--------------+
The domains look like this:
###DOMAIN_VALUES_VW +------------+------+-------------+ | DOMAIN | CODE | DESCRIPTION | +------------+------+-------------+ | DOMAIN_ABC | A | EH | | DOMAIN_ABC | B | BEE | | DOMAIN_ABC | C | SEE | +------------+------+-------------+ | DOMAIN_XYZ | X | EX | | DOMAIN_XYZ | Y | WHY | | DOMAIN_XYZ | Z | ZEE | +------------+------+-------------+
The source is an xml column in a single system table; I've extracted all the domains into this view.
##Question
For validation purposes, I have made a query that will check if there are values in a field that do not match the corresponding domain:
INSERT INTO ENG.CV_ERRORS
(TABLE_NAME, FIELD_NAME, ERROR)
SELECT
'TABLE_1' AS TABLE_NAME
,'FIELD_1' AS FIELD_NAME
,FIELD_1 AS ERROR
FROM
ENG.TABLE_1
LEFT JOIN
(
SELECT CODE
FROM INFRASTR.D_CV_ENG_VW
WHERE DOMAIN = 'DOMAIN_ABC'
)
ON FIELD_1 = CODE
WHERE
FIELD_1 IS NOT NULL
AND CODE IS NULL
+------------+------------+-------------+
| TABLE_NAME | FIELD_NAME | ERROR |
+------------+------------+-------------+
| TABLE_1 | FIELD_1 | BLACK SHEEP |
+------------+------------+-------------+
However, this query is hardcoded to be run on a single field, in a single table at a time. I need to check all of the fields with domains, in all of the tables in the database - programmatically.
How can I do this? I'm pretty sure this can be done with PL/SQL and dynamic SQL, but I'm so new to PL/SQL that it is proving to be rather difficult.
