RE: SQL translation

John,

The ON phrase goes with the LEFT OUTER JOIN clause and specifies the
conditions used to "connect" the joined database with the other databases in
the statement. I've reformatted the SQL statement below to show the
different sections more clearly.

MONO (and FREE) are parameters to the @Prompt function. From what I've read
via Google, MONO means the user selects a single value.

Hope this helps!
Richard

Subject: SQL translation

I have been shown a rather complex SQL statement. My knowledge of SQL is
limited. I am attempting to translate the query to the language used by
Business Objects.

This is the SQL statement:


SELECT
count(dbo.VISIT.P_KEY),
datepart(mm,( dbo.VISIT.ARRIVALDT )),
TriageAcuityMstrLst.URGENCY
FROM
dbo.VISIT LEFT OUTER JOIN dbo.ACUITYASSESSMENT TriageAcuityAssessment ON
TriageAcuityAssessment.VISIT_FK=dbo.VISIT.P_KEY and
TriageAcuityAssessment.Acuity_SVC_FK = '00000000000A2'
LEFT OUTER JOIN dbo.ACUITYMSTRLST TriageAcuityMstrLst ON
TriageAcuityMstrLst.P_KEY=TriageAcuityAssessment.ACUITYMSTR_FK
WHERE
( dbo.VISIT.Status_SVC_FK != '00000000001JY' and dbo.VISIT.Status_SVC_FK
!= '00000000000AQ' )
AND (
( ( dbo.VISIT.ARRIVALDT ) >= @Prompt('Select Beginning Date', 'A',, MONO,
FREE) AND ( dbo.VISIT.ARRIVALDT ) <= (@Prompt('Select Ending Date', 'A',,
MONO, FREE) + ' 23:59:59') )
)
GROUP BY
datepart(mm,( dbo.VISIT.ARRIVALDT )),
TriageAcuityMstrLst.URGENCY


Questions:
1) On the FROm clause, what does the ON phrase mean? If that is part of
record selection, why isn't it on the WHERE clause?

2) On the WHERE clause what does MONO mean?
