Oracle文本catsearch一个谓词中的多个
我有一个表,有两列,类型为varchar2 我创建了两个索引Oracle文本catsearch一个谓词中的多个,oracle,text,Oracle,Text,我有一个表,有两列,类型为varchar2 我创建了两个索引 CREATE INDEX DOC_IDX_1 ON DOCUMENTO ( column1 ) INDEX TYPE IS CTXSYS.CTXCAT ; CREATE INDEX DOC_IDX_2 ON DOCUMENTO ( column2 ) INDEX TYPE IS CTXSYS.CTXCAT ; 当我执行查询时 select * from table1 where CATSEARCH(colum
CREATE INDEX DOC_IDX_1
ON DOCUMENTO
( column1
)
INDEX TYPE IS CTXSYS.CTXCAT
;
CREATE INDEX DOC_IDX_2
ON DOCUMENTO
( column2
)
INDEX TYPE IS CTXSYS.CTXCAT
;
当我执行查询时
select *
from table1
where CATSEARCH(column1, 'AAA', NULL) > 0
AND CATSEARCH(column2 , 'BBBb', NULL) > 0
我得到以下错误
ORA-20000: Oracle Text error:
DRG-10849: catsearch non supporta il richiamo funzionale
DRG-10599: la colonna non è indicizzata
20000. 00000 - "%s"
*Cause: The stored procedure 'raise_application_error'
was called which causes this error to be generated.
*Action: Correct the problem as described in the error message or contact
the application administrator or DBA for more information.
英文译本如下:
$ oerr drg 10849
10849,0, "catsearch does not support functional invocation"
// *Cause: the query plan for your query is invoking a catsearch operator
// functionally rather than as an index rowsource. The catsearch
// operator does not support functional invocation
// *Action: add optimizer hints so that all catsearch operators are
// performed through index scans
// *Mnemonic: QE_CATSEARCH_FUNCINV
//

我怎样才能解决这个问题
谢谢

文档o
如果您做得不对,首先,在ctxsys模式中,您应该以以下方式设置首选项:
begin
ctx_ddl.create_preference('my_documents', 'MULTI_COLUMN_DATASTORE');
ctx_ddl.set_attribute('my_documents', 'COLUMNS', 'column1, column2');
ctx_ddl.create_preference('my_documents_lexer', 'BASIC_LEXER'); /* I strongly recommend you this preference*/
ctx_ddl.set_attribute('my_documents_lexer', 'BASE_LETTER', 'YES');
end;
/
select *
from documento
where contains(column1,'AAA WITHIN column1 AND BBBb WITHIN column2')>0
运行上述脚本后,即可创建索引:
create index DOC_IDX on DOCUMENTO(column1) indextype is ctxsys.context
parameters ('DATASTORE ctxsys.my_documents section group CTXSYS.AUTO_SECTION_GROUP LEXER ctxsys.my_documents_lexer SYNC(on commit)');
您的查询可能是这样工作的:
begin
ctx_ddl.create_preference('my_documents', 'MULTI_COLUMN_DATASTORE');
ctx_ddl.set_attribute('my_documents', 'COLUMNS', 'column1, column2');
ctx_ddl.create_preference('my_documents_lexer', 'BASIC_LEXER'); /* I strongly recommend you this preference*/
ctx_ddl.set_attribute('my_documents_lexer', 'BASE_LETTER', 'YES');
end;
/
select *
from documento
where contains(column1,'AAA WITHIN column1 AND BBBb WITHIN column2')>0
