# Will test following scenarios:					#
# 1. Create/Drop of temp-table. (with and w/o explicit pk)		#
# 2. Truncate temp-table (result in table drop and recreate).		#
# 3. Alter of temp-table.						#
# 4. Import/Discard of temp-table (to check blocked action)		#
# 5. Renaming of temp-table						#
# 6. Creating temp-table with large prefix enabled.			#
# 7. Check Temp table info not stored in I_S datafile and tables	#
