PARSE
Updated: 31 July 2009
Use PARSE to find a word in a string based on its word position in the string.
Syntax
SELECT [wctString].[wct].[PARSE] (
<@Text, nvarchar(max),>
,<@Delimiters, nvarchar(4000),>
,<@WordNo, int,>)
Arguments
@Text
is the text value to be evaluated. The @Text argument can be of data types that are implicitly convertible to nvarchar or ntext.
@Delimiters
the value or values used to separate words. The @Delimiters argument can be of data types that are implicitly convertible to nvarchar or ntext.
@Wordno
the word number, relative to all other words, to be retrieved. The @Wordno argument can be an expression of types that are implicitly convertible to int.
Return Types
nvarchar(max)
Remarks
· You can enter multiple @Delimiters, separating them by a semi-colon (;). Usually space is a delimiter, but you might consider m-dash (CHAR(151)) or non-breaking space (CHAR(160)) as delimiters.
· If @Wordno < 1, then an error is returned.
· If @Wordno > NUMWORDS(@Text, @Delimiters), then a blank is returned.
· If @Text is NULL, then an error is returned.

wct.PARSE('Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal. Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. But, in a larger sense, we can not dedicate—we can not consecrate—we can not hallow—this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us—that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion—that we here highly resolve that these dead shall not have died in vain—that this nation, under God, shall have a new birth of freedom—and that government of the people, by the people, for the people, shall not perish from the earth.'
