Hello,
I am needing to create a table view that will return resutls for 7 different aliases from the same column.
Individual statements work as expected, how can I create a single statement to return all 7 values?
Or is there another approach I need to consider to accomplis this.
'char' fields ar varchar(160 and 'decimal' fields are decimal(21,6).
Thanks for any advice you can provide.

SELECT system_id, job_id, sub_job_id, sequence, free_field_char As [QAAuditSamples]
            FROM jobfreefield
            WHERE system_id = 'ABC' and sequence = 28
SELECT system_id, job_id, sub_job_id, sequence, free_field_decimal As [QAQtyInspected]
            FROM jobfreefield
            WHERE system_id = 'ABC' and sequence = 921
SELECT system_id, job_id, sub_job_id, sequence, free_field_decimal As [QASavesChecked]
            FROM jobfreefield
            WHERE system_id = 'ABC' and sequence = 922
SELECT system_id, job_id, sub_job_id, sequence, free_field_decimal As [QADefectsFound]
            FROM jobfreefield
            WHERE system_id = 'ABC' and sequence = 923
SELECT system_id, job_id, sub_job_id, sequence, free_field_decimal As [QAPiecesDefect]
            FROM jobfreefield
            WHERE system_id = 'ABC' and sequence = 924
SELECT system_id, job_id, sub_job_id, sequence, free_field_decimal As [QADefectCode]
            FROM jobfreefield
            WHERE system_id = 'ABC' and sequence = 925
SELECT system_id, job_id, sub_job_id, sequence, free_field_char As [QAVarianceApprovedBy]
            FROM jobfreefield
            WHERE system_id = 'ABC' and sequence = 926
SELECT system_id, job_id, sub_job_id, sequence, free_field_char AS [QAComments]
            FROM jobfreefield
            WHERE system_id = 'ABC' and sequence = 927

Maybe something like this?:

SELECT system_id, job_id, sub_job_id,
    MAX(CASE WHEN sequence =  28 THEN free_field_char END) AS [QAAuditSamples],
    MAX(CASE WHEN sequence = 921 THEN free_field_decimal END) AS [QAQtyInspected],
    MAX(CASE WHEN sequence = 922 THEN free_field_decimal END) AS [QASavesChecked],
    MAX(CASE WHEN sequence = 923 THEN free_field_decimal END) AS [QADefectsFound],
    MAX(CASE WHEN sequence = 924 THEN free_field_decimal END) AS [QAPiecesDefect],
    MAX(CASE WHEN sequence = 925 THEN free_field_decimal END) AS [QADefectCode],
    MAX(CASE WHEN sequence = 926 THEN free_field_char END) AS [QAVarianceApprovedBy],
    MAX(CASE WHEN sequence = 927 THEN free_field_char END) AS [QAComments]
FROM dbo.jobfreefield
WHERE system_id = 'ABC'
GROUP BY
    system_id, job_id, sub_job_id
ORDER BY
    system_id, job_id, sub_job_id
