I have a private variable:

private nValue as Long

When I use this value after it has been set in a string I keep getting mismatch errors:

    sSql = "SELECT Business_Entity_Name, Primary_Entity_ID, Entity_Type_ID, " + _
           "User_Rights.Business_Entity_ID AS Business_Entity_ID, User_Rights_ID " + _
           "FROM User_Rights, User_Info, Business_Entity WHERE User_Rights.User_ID = " + cstr(nValue ) + _
           " AND Business_Entity.Business_Entity_ID = User_Rights.Business_Entity_ID"

I have also tried
CInt( nValue )

it only works when I do this:
    sSql = "SELECT Business_Entity_Name, Primary_Entity_ID, Entity_Type_ID, " + _
           "User_Rights.Business_Entity_ID AS Business_Entity_ID, User_Rights_ID " + _
           "FROM User_Rights, User_Info, Business_Entity WHERE User_Rights.User_ID = 1" + _
           " AND Business_Entity.Business_Entity_ID = User_Rights.Business_Entity_ID"

any ideas why I have this problem?

It looks like your field "User_Rights.User_ID" is looking for an integer .. use CInt(nValue) instead of CStr(nValue).

The concatination operation is not +, it's & (if it isn't javascript code :) ). Try it.

sSql = "SELECT Business_Entity_Name, Primary_Entity_ID, Entity_Type_ID, " & _
           "User_Rights.Business_Entity_ID AS Business_Entity_ID, User_Rights_ID " & _
           "FROM User_Rights, User_Info, Business_Entity WHERE User_Rights.User_ID = " & nValue & _
           " AND Business_Entity.Business_Entity_ID = User_Rights.Business_Entity_ID"

The concatination is obviously not the problem, Yury, as he stated earlier, his second SQL string worked properly. The problem lies in converting the variable to the proper datatype - in this case either a number or integer.

Again, using CInt(nValue) should do exactly what you need, eric07.
