I have a comments field that has certain values I want to extract into it's own field(new must be created). What is the syntax for doing this?
the data looks like this:
Comments
5321025 HOLLAND BL 60X210 20 Unts $5.91 Unt
5321032 HOLLAND BL 60X210 6 Unts $5.91 Unt
5321124 HOLLAND BL 120X210 13 Unts $8.64 Unt

it depends;

your limited example data implies an order to the comments, so you could use the DelimitedSplit8K function[/url]

to split the values out to related rows, and insert/update based on that.

With MyCTE (Comments)

AS

(

SELECT '5321025 HOLLAND BL 60X210 20 Unts $5.91 Unt' UNION ALL

SELECT '5321032 HOLLAND BL 60X210 6 Unts $5.91 Unt' UNION ALL

SELECT '5321124 HOLLAND BL 120X210 13 Unts $8.64 Unt'

)

SELECT

MyCTE.*,

T1.*

FROM MyCTE

CROSS APPLY dbo.DelimitedSplit8K(Comments,' ') T1

Sorry, I forgot to specify I only need the units and the amounts. ie

comments:

5321063 HOLLAND BL 90X210 10 Unts $7.27 Unt

5321070 HOLLAND BL 90X210 1 Unts $7.27 Unt

5321124 HOLLAND BL 120X210 13 Unts $8.64 Unt

my 2 new fields should be :

Units UnitPrice

10 $7.27

1 $7.27

13 $8.64

As Lowell already stated, if the comments have a consistent pattern you can use the DelimitedSplit8K function. Just need to add a where clause.

With MyCTE (Comments)

AS

(

SELECT '5321025 HOLLAND BL 60X210 20 Unts $5.91 Unt' UNION ALL

SELECT '5321032 HOLLAND BL 60X210 6 Unts $5.91 Unt' UNION ALL

SELECT '5321124 HOLLAND BL 120X210 13 Unts $8.64 Unt'

)

SELECT

MyCTE.*,

T1.*

FROM MyCTE

CROSS APPLY dbo.DelimitedSplit8K(Comments,' ') T1

where ItemNumber in (5, 7)

If your Comments column does not fit a consistent pattern this can be exponentially more difficult depending on the actual contents.
