Today, I will talk to you about how to achieve full-text retrieval in the SQLServer database, many people may not know much about it. In order to make you understand better, the editor summarized the following content for you. I hope you can get something according to this article.

How to realize full-text Retrieval in SQLServer Database

(1) start the full-text processing function of the database (sp_fulltext_datebase)

(2) establish full-text catalogue (sp_fulltext_catalog)

(3) register tables that require full-text indexing in the full-text catalog (sp_fulltext_table)

(4) indicate the column names in the table that require full-text retrieval (sp_fulltext_column)

(5) create a full-text index for the table (sp_fulltext_table)

(6) populate full-text index (sp_fulltext_catalog).

How to realize full-text Retrieval in SQLServer Database

Start sqlserver's full-text search service, the microsoftsearch service, before executing the script.

Usepubs-- opens the database go

-- check if pubs supports full-text indexing, and if not, use sp_fulltext_datebase to turn on the feature.

If (selectdatabaseproperty ('pubs','IsFulltextEnables')) = 0 executespice fulltext database enable.'

-- establish a full-text catalog FT_pubs.

Executesp_fulltext_catalog'FT_pubs','create'

-- create a full-text index data element for the titles table.

Executesp_fulltext_table'titles','FT_pubs','UPKCL_titleidind'

-- sets the full-text index column name.

Executesp_fulltext_column'titles','title','add'executesp_fulltext_column'titles','notes','add'

-- establish a full-text index.

Executesp_fulltext_table'FT_pubs','activate'

-- populate the full-text index catalog.

Executesp_fulltext_catalog'FT_pubs','start_full'GO

-- check the filling of full-text catalogs.

WHILEFulltextCatalogProperty ("FT_pubs','PopulateStatus') 0BEGIN

If the full-text catalog is populated, wait 30 seconds and then check again.

WAITFORDELAY'0:0:30'END

-- after filling in the full-text catalog, use the full-text catalog for retrieval.

Query the name of a book that contains a database or computer string in the title column or the notes column.

SELECTtitleFROMtitlewhereCONTAINTS (title,'database') orcontains (notes,'database') orcontains (title,'computer') orcontains (notes,'computer')
