Hi,
Just another question about this subject.
It is possible to compare if these 3 PlpgSQL arrays have the same
number of elements? How to get the number of elements of an PLpgSQL
array?
NOTICE: file types: {image,image,image,image,image}
NOTICE: file details: {type,width,height,html_width_height,mime}
NOTICE: values: {jpg,343,515,"width=\"343\" height=\"515\"",image/jpeg}
Best Regards,
