HEllo Team,

I have the following Query.

SQL

select  ID,CUSTOMERLOANOCRID,FILELOGID,[FILENAME],BATCHID,RECORDNO,FIRSTNAME,
MIDDLENAME,LASTNAME,GENDER,FULLADDRESS,CUSTOMERADDR1,CUSTOMERADDR2,LANDMARK,CITY,STATE,
    PINCODE ,   LANDLINENO,     MOBILENO1 , MOBILENO2 , EMAILID ,   DOB ,   ADDRVERIFY ,
    PHOTOVERIFY ,   LOAN1AMT ,  LOAN1INTRRATE, LOAN2AMT,LOAN2INTRRATE,DATEOFEMI,RELEASEDATE,
    MOTHERNAME ,    HOUSETYPE ,COMPANYNAME,SALARY,IMAGENAME ,   IMAGERECORDNO,  QCTOVERIFY ,
    QCUSERID ,  CREATEDBY , CREATEDON , UPDATEDBY , UPDATEDON , DELETED ,QCUSERID ,QCTOVERIFY,
QCTOVERIFYREMARKS from CUSTOMERLOANDATA with(nolock)
where FILELOGID=(select top(1) filelogid  from CUSTOMERLOANDATA with(nolock)
 where  isnull (QCTOVERIFY , 0) and QCUSERID = 13 order by id asc) and isnull (QCTOVERIFY, 0)

I am getting the error

SQL

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

Kindly tell me where i am making the mistake.

You have no condition in the ISNULL part. ISNULL does not returns a true or false id the column passed to it is null, rather the second parameter.
In your case

SQL

ISNULL(QCTOVERIFY, 0)

Will return the value of QCTOVERIFY if it's not null and 0 it it is null.
So you have to change your ISNULL question like this:

SQL

ISNULL(QCTOVERIFY, 0) = 0

if you check for null

SQL

ISNULL(QCTOVERIFY, 0) <> 0

if you check for non-null
