What is the password to extract the 1.7G file of 2000W data in a hotel?
The basic definition of a hotel is a business organization that provides users with a safe and comfortable space for a short rest or sleep. Generally speaking, it is a place for guests to stay and eat. Specifically, a hotel is an organization that provides services to its guests through the sale of rooms, restaurants and comprehensive service facilities, taking its buildings as evidence, so as to obtain economic benefits.

Because sql20 12 can only be installed on win7 system. The software can be obtained from the download page. Just download and install.
Step 1: Open SQLservermanagementstudio.
Step 2: Right-click the red circle "Database"-"Restore Database"
Step 3: Confirm the import-wait for the completion, and the database will appear.
Step 4: Right-click the front 1000 line, and a diagram will appear on the right. As you can see, using these codes, you can display 1000 lines of information.
Step 5: Then we will remove top 1000.
Step 6: Then the most important thing is to add at the bottom.
Finally: Click "Execute" and the result will appear below. I use ssd to search, and it takes about 10 seconds to complete the search. Let's weigh it for ourselves.

Use of vacuum cleaner
The dust collector is mechanically connected with the power supply. The power supply drives the motor to rotate at high speed through the filter plate and the power switch, and the blades rotate, so that the air is discharged at high speed. However, the air in the dust suction part at the front end of the fan does not supplement the air of the fan, resulting in an instantaneous vacuum inside the machine and a negative pressure difference with the outside. Under the action of negative pressure difference, the machine sucks in dusty air and discharges clean air after being filtered by the dust filter.
1 Clean the sundries and all dust-collecting accessories in the bucket in time, and clean the dust-collecting bag after each work.
Check whether there is any perforation or air leakage, thoroughly clean the dust grid and dust bag with detergent and warm water, and blow dry. It is forbidden.
Dry dust bag.
2 Check whether the power cord and plug are damaged. After use, the power coil is wound into a bundle and hung on the hook of the headgear.
3 Check whether the air inlet is blocked or sundries after water absorption, otherwise it needs cleaning. Check whether the floating wave is damaged.
4 When using the machine, handle it with care, and do not use external force to impact the mobility.
6 When cleaning the machine, please wipe it with a wet cloth containing water or a neutral detergent. It is forbidden to immerse the main engine head in water for cleaning. Do not use it.
Gasoline, banana oil and other corrosive cleaning agents, otherwise it will lead to cracking of the shell.
7 Don't let the machine work continuously for a long time. Please control the continuous working time within 2 hours, otherwise it will
Affect machine life.
If the vacuum cleaner is used for a long time, the suction will decrease because the mesh of the filter screen is blocked. To prevent inhalation
Clean the filter screen and cloth bag with water regularly, and then use it to restore suction after drying in the shade.
If the main engine is hot, smells of burning, or has abnormal vibration and noise, it should be repaired in time. Don't use it reluctantly.
Do not bend the 10 hose frequently, and do not stretch and bend it excessively.
Folding suction inspection
How to detect non-suction: 1 First, separate the accessories from the barrel at the square mouth. Just don't assemble parts.
Start the machine and put your hand on the square mouth, if there is no suction.
Just check whether there is air leakage in the bucket, whether the bucket apron is damaged, whether the dustproof net is blocked, whether the motor is aging, and whether the floating wave blocks the air inlet.
You can replace it when you find it.
If suction is detected, it means that the joint is leaking, broken or damaged. Accessories include short connectors, hoses and long connectors.
Joints, steel pipes and dust covers should be installed in sequence, and then check their suction. If found, it can be replaced.
The reason why there is no suction in folding.
1 the inevitable problem of all machinery is wear and tear, which will age after a long time and the suction is not as good as that of the new machine. Of course, all companies are trying to do well.
The machinery in factories and enterprises has been blocked for a long time because there is no special person to clean it.
When the accessories are not well maintained, hoses, square mouths, steel pipes, joints, etc. They are all wear, cracking and porosity, which has a lot to do with suction.
On some uneven floors and carpets, some are heavy or difficult to suck, so they also need strong suction.
Of course, strong suction can be more efficient and save time, and cleaners can improve work efficiency.
For some special objects, such as cement, flour or sticky things, the requirements for suction are even greater.
7 Vacuum range hood must confirm whether the filter is installed when vacuuming. If it is a wet and dry vacuum cleaner, remove the filter screen when absorbing water.
Method of purchasing folding editing this paragraph
The rated input power of 1. must match the rated capacitance of the user's home, and it is generally better to be below 1500 watts. Commercially, it is 1500 watt.
2. Electrical nameplates should have complete electrical parameters.
3. The vacuum cleaner packaging boxes produced by regular manufacturers are neat and firm, and the instructions, certificates and warranty books must be complete, with complete accessories, flat appearance and elegant appearance.
4. All parts should be closely connected, especially the joint of dust collection part and power supply part. The inspection method is: turn on the power switch and put your hands near the intersection. If there is no feeling of air leakage, the sealing is good, otherwise the vacuum cleaner with poor sealing is not only poor in dust collection effect, but also consumes a lot of electricity.
5. The motor drags the blade to generate negative pressure. Therefore, when evaluating its dust removal performance, turn on the power supply and put your hand near the dust suction port, which has obvious suction. The greater the suction force, the better the vacuum or water absorption effect of the appliance. On the contrary, it is not.
6. At present, the power cord of horizontal vacuum cleaner has the function of automatic rewinding. Try to pull out a section of power cord and press the rewind button to check whether its action is sensitive and reliable.
7. The minimum noise of vacuum cleaner is better.
8. Check whether the vacuum cleaner to be purchased has 3C certification mark.
