SQL Server 2000

Is a predicate used to search columns containing character-based data types for precise or fuzzy (less precise) matches to single words and phrases, the proximity of words within a certain distance of one another, or weighted matches. CONTAINS can search for:

  • A word or phrase.

  • The prefix of a word or phrase.

  • A word near another word.

  • A word inflectionally generated from another (for example, the word drive is the inflectional stem of drives, drove, driving, and driven).

  • A word that has a higher designated weighting than another word.

    ( { column | * } , '< contains_search_condition >'

< contains_search_condition > ::=
{ < simple_term >
        | < prefix_term >
        | < generation_term >
        | < proximity_term >
        | < weighted_term >
        | { ( < contains_search_condition > )
        { AND | AND NOT | OR } < contains_search_condition > [ ...n ]

< simple_term > ::=
    word | " phrase "

< prefix term > ::=
    { "word * " | "phrase * " }

< generation_term > ::=
    FORMSOF ( INFLECTIONAL , < simple_term > [ ,...n ] )

< proximity_term > ::=
    { < simple_term > | < prefix_term > }
    { { NEAR | ~ } { < simple_term > | < prefix_term > } } [ ...n ]

< weighted_term > ::=
        ( { {
                < simple_term >

                | < generation_term >
                | < proximity_term >
            [ WEIGHT ( weight_value ) ]
            } [ ,...n ]



Is the name of a specific column that has been registered for full-text searching. Columns of the character string data types are valid full-text searching columns.


Specifies that all columns in the table registered for full-text searching should be used to search for the given contains search condition(s). If more than one table is in the FROM clause, * must be qualified by the table name.


Specifies some text to search for in column.


Is a string of characters without spaces or punctuation.


Is one or more words with spaces between each word.

Note  Some languages, such as those in Asia, can have phrases that consist of one or more words without spaces between them.


Specifies a match for an exact word (one or more characters without spaces or punctuation in single-byte languages) or a phrase (one or more consecutive words separated by spaces and optional punctuation in single-byte languages). Examples of valid simple terms are "blue berry", blueberry, and "Microsoft SQL Server". Phrases should be enclosed in double quotation marks (""). Words in a phrase must appear in the same order as specified in <contains_search_condition> as they appear in the database column. The search for characters in the word or phrase is case insensitive. Noise words (such as a, and, or the) in full-text indexed columns are not stored in the full-text index. If a noise word is used in a single word search, SQL Server returns an error message indicating that only noise words are present in the query. SQL Server includes a standard list of noise words in the directory \Mssql\Ftdata\Sqlserver\Config.

Punctuation is ignored. Therefore, CONTAINS(testing, "computer failure") matches a row with the value, "Where is my computer? Failure to find it would be expensive."


Specifies a match of words or phrases beginning with the specified text. Enclose a prefix term in double quotation marks ("") and add an asterisk (*) before the ending quotation mark, so that all text starting with the simple term specified before the asterisk is matched. The clause should be specified this way: CONTAINS (column, '"text*"') The asterisk matches zero, one, or more characters (of the root word or words in the word or phrase). If the text and asterisk are not delimited by double quotation marks, as in CONTAINS (column, 'text*'), full-text search considers the asterisk as a character and will search for exact matches to text*.

When <prefix_term> is a phrase, each word contained in the phrase is considered to be a separate prefix. Therefore, a query specifying a prefix term of "local wine *" matches any rows with the text of "local winery", "locally wined and dined", and so on.


Specifies a match of words when the included simple terms include variants of the original word for which to search.

Specifies that the plural and singular, as well as the gender and neutral forms of nouns, verbs, and adjectives should be matched. The various tenses of verbs should be matched too.

A given <simple_term> within a <generation_term> will not match both nouns and verbs.


Specifies a match of words or phrases that must be close to one another. <proximity_term> operates similarly to the AND operator: both require that more than one word or phrase exist in the column being searched. As the words in <proximity_term> appear closer together, the better the match.

NEAR | ~
Indicates that the word or phrase on the left side of the NEAR or ~ operator should be approximately close to the word or phrase on the right side of the NEAR or ~ operator. Multiple proximity terms can be chained, for example:
a NEAR b NEAR c 

This means that word or phrase a should be near word or phrase b, which should be near word or phrase c.

Microsoft® SQL Server™ ranks the distance between the left and right word or phrase. A low rank value (for example, 0) indicates a large distance between the two. If the specified words or phrases are far apart from each other, the query is considered to be satisfied; however, the query has a very low (0) rank value. However, if <contains_search_condition> consists of only one or more NEAR proximity terms, SQL Server does not return rows with a rank value of 0. For more information about ranking, see CONTAINSTABLE.


Specifies that the matching rows (returned by the query) match a list of words and phrases, each optionally given a weighting value.

Specifies the <weighted_term> keyword.
WEIGHT (weight_value)
Specifies a weight value, which is a number from 0.0 through 1.0. Each component in <weighted_term> may include a weight_value. weight_value is a way to change how various portions of a query affect the rank value assigned to each row matching the query. Weighting forces a different measurement of the ranking of a value because all the components of <weighted_term> are used together to determine the match. A row is returned if there is a match on any one of the ISABOUT parameters, whether or not a weight value is assigned. To determine the rank values for each returned row that indicates the degree of matching between the returned rows, see CONTAINSTABLE.


Specifies a logical operation between two contains search conditions. When <contains_search_condition> contains parenthesized groups, these parenthesized groups are evaluated first. After evaluating parenthesized groups, these rules apply when using these logical operators with contains search conditions:

  • NOT is applied before AND.

  • NOT can only occur after AND, as in AND NOT. The OR NOT operator is not allowed. NOT cannot be specified before the first term (for example, CONTAINS (mycolumn, 'NOT "phrase_to_search_for" ' ).

  • AND is applied before OR.

  • Boolean operators of the same type (AND, OR) are associative and can therefore be applied in any order.


Is a placeholder indicating that multiple contains search conditions and terms within them can be specified.


CONTAINS is not recognized as a keyword if the compatibility level is less than 70. For more information, see sp_dbcmptlevel.

A. Use CONTAINS with <simple_term>

This example finds all products with a price of $15.00 that contain the word "bottles".

USE Northwind
SELECT ProductName
FROM Products
WHERE UnitPrice = 15.00
   AND CONTAINS(QuantityPerUnit, 'bottles')
B. Use CONTAINS and phrase in <simple_term>

This example returns all products that contain either the phrase "sasquatch ale" or "steeleye stout".

USE Northwind
SELECT ProductName
FROM Products
WHERE CONTAINS(ProductName, ' "sasquatch ale" OR "steeleye stout" ')
C. Use CONTAINS with <prefix_term>

This example returns all product names with at least one word starting with the prefix choc in the ProductName column.

USE Northwind
SELECT ProductName
FROM Products
WHERE CONTAINS(ProductName, ' "choc*" ')
D. Use CONTAINS and OR with <prefix_term>

This example returns all category descriptions containing the strings "sea" or "bread".

USE Northwind
SELECT CategoryName
FROM Categories
WHERE CONTAINS(Description, '"sea*" OR "bread*"')
E. Use CONTAINS with <proximity_term>

This example returns all product names that have the word "Boysenberry" near the word "spread".

USE Northwind
SELECT ProductName
FROM Products
WHERE CONTAINS(ProductName, 'spread NEAR Boysenberry')
F. Use CONTAINS with <generation_term>

This example searches for all products with words of the form dry: dried, drying, and so on.

USE Northwind
SELECT ProductName
FROM Products
G. Use CONTAINS with <weighted_term>

This example searches for all product names containing the words spread, sauces, or relishes, and different weightings are given to each word.

USE Northwind
SELECT CategoryName, Description
FROM Categories
WHERE CONTAINS(Description, 'ISABOUT (spread weight (.8), 
   sauces weight (.4), relishes weight (.2) )' )
H. Use CONTAINS with variables

This example uses a variable instead of a specific search term.

USE pubs
DECLARE @SearchWord varchar(30)
SET @SearchWord ='Moon'
SELECT pr_info FROM pub_info WHERE CONTAINS(pr_info, @SearchWord)
