An expression of non boolean type!!!

Posted on 2015-01-20

Hi all,

I have an SSRS project that has a dataset which includes the following where clause:

((@Resource IN ('Newhouse Section Fit out') and dbo.OPERATION_SCHED.RESOURCE_ID IN ('NE_BLAST',
(@Resource IN ('Newhouse TNT Fit out') and dbo.OPERATION_SCHED.RESOURCE_ID IN ('NE_BLAST02',
(@Resource NOT IN ('Newhouse Section Fit out','Newhouse TNT Fit out')  AND dbo.OPERATION_SCHED.RESOURCE_ID IN (@Resource)))
                      (dbo.OPERATION_SCHED.START_DATE <= @EndDate) AND (dbo.OPERATION_SCHED.SCHEDULE_ID = @ScheduleID)

Open in new window

@Resource is a parameter that allows multiple selection from a predefined dropdown.
@ScheduleID is a parameter that allows single selection from a predefined dropdown.
@StartDate & @EndDate are parameters that receive their value from calendar selections.

I believe the issue I have surrounds the @Resource parameter in this where clause... The problem is, I can't work out what it is!

I get an error as follows:

An expression of non-boolean type specified in a context where a condition is expected, near ','

This error only occurs when I select more than one option from the dropdown.

Can anyone point me in the right direction?

Thanks in advance.

Line 18 --> IN (@Resource)))
Looks like you have one too many right parens, or are missing a left paren somewhere.

Disregard the above.

>@Resource is a parameter that allows multiple selection from a predefined dropdown.
So ... you are expecting to pass a single comma-delimeted parameter such as 'CA, NY, FL', and insert it into a query.  Won't work that way.

I'll ping SQL Server expert ValentinoV and have him comment here, as he's dealt with this situation before in SSRS, and I can't find the article he wrote on it.

Hi Fmabey,

Here isssue with query not with ssrs report.

Check this first query:

WHERE ('a') IN ('a','b','c')

Open in new window

In above query consider 'a' as resource and query works well.But in below query resource value is ('a','b') - multiple value for this case query will fail.

WHERE ('a','b') IN ('a','b','c')

Open in new window

Error with query would be
An expression of non-boolean type specified in a context where a condition is expected, near ','.

To avoid this can you can use UNION ALL to fix problem.

I believe Jim is referring to the following article: Reporting On Data From Stored Procedures (part 2)

I know it might be a lot to go through but as you're using multi-valued parameters I believe it's worth the effort :)

Let me know if you have any further questions on that!
