A sintaxe para o
UPDATE declaração
é:
Update_set_clause ::=
Você não pode fazer:
UPDATE table_name
CASE WHEN ... THEN SET ...
WHEN ... THEN SET ...
Provavelmente será mais fácil dividi-lo em várias instruções:
UPDATE TEMP_PARSE_EXIST
SET ADT_ACT = 'CASE 1',
V_NUM = REGEXP_SUBSTR(REGEXP_SUBSTR(ADRS, '^\w+(\s?-\s?)\w+'), '\d+$')
WHERE ADT_ACT IS NULL
AND REGEXP_LIKE(REGEXP_SUBSTR(ADRS, '^\w+(\s?-\s?)\w+\s\w+', 'i'), '(ABBEY|ACRES|ALLÉE|ALLEY|AUT|AUTOROUTE|AV|AVE|AVENUE|BAY|BEACH|BEND|BLVD|BOUL|BOULEVARD|BYPASS|WYND)$', 'i')
AND REGEXP_LIKE(REGEXP_SUBSTR(ADRS, '^\w+(\s?-\s?)\w+'), '^\w+(\s?-\s?)\d+$');
UPDATE TEMP_PARSE_EXIST
SET ADT_ACT = 'CASE 2',
V_STREET_NAME = REGEXP_SUBSTR(REGEXP_SUBSTR(ADRS, '^\w+(\s?-\s?)\w+'), '\d+(ST|ND|RD|TH)$')
WHERE ADT_ACT IS NULL
AND REGEXP_LIKE(REGEXP_SUBSTR(ADRS, '^\w+(\s?-\s?)\w+\s\w+', 'i'), '(ABBEY|ACRES|ALLÉE|ALLEY|AUT|AUTOROUTE|AV|AVE|AVENUE|BAY|BEACH|BEND|BLVD|BOUL|BOULEVARD|BYPASS|WYND)$', 'i')
AND REGEXP_LIKE(REGEXP_SUBSTR(ADRS, '^\w+(\s?-\s?)\w+'), '^\w+(\s?-\s?)\d+(ST|ND|RD|TH)$');
...
Atualizar :
As expressões regulares podem ser simplificadas (ou pelo menos reduzir a duplicação e o aninhamento das expressões):
UPDATE TEMP_PARSE_EXIST
SET ADT_ACT = 'CASE 2',
V_STREET_NAME = REGEXP_SUBSTR( ADRS, '^\w+(\s?-\s?)(\d+(ST|ND|RD|TH))', 1, 1, 'i', 2 )
WHERE ADT_ACT IS NULL
AND REGEXP_LIKE( '^\w+(\s?-\s?)\d+(ST|ND|RD|TH)\s\w*(ABBEY|ACRES|ALLÉE|ALLEY|AUT|AUTOROUTE|AV|AVE|AVENUE|BAY|BEACH|BEND|BLVD|BOUL|BOULEVARD|BYPASS|WYND)', 'i' );
