The spacing of the gobo and the lens may be varied to alter the size and focus of the image. A gobo in a gobo holder, which goes in a stage lighting instrument. The discolored portion is oxidation of the stainless steel caused by the high temperature of the lamp, but the gobo is still usable.he spacing of the gobo and the lens may be varied to alter the size and focus of the image.

The column â%.*lsâ cannot be modified because it is either a computed column or is the result of a UNION operator. The column â%.*lsâ cannot be modified because it is either a computed column or is the result of a UNION operator.
First, I need to make sure the computed field is persisted and the caveat on that is that only deterministic values can be computed. Not only that, the computed field must be derived directly from columns in the table, rather than other functions that look at other tables.
