I have all table ( all table scripts in single file ),Udds ( all udds in single file ),Stored procedures( separate file for each SPs ),Functions ( Separate file for each Functions ),Triggers and views scripts in.SQL file. Can anybody tell me how to create batch file for executing all these scripts in sql server? Batch file local variables sql. Is there any way to retreive the result set of a sql query in a local variable; the query is to be run in a batch file. What I am trying to do is something like this. I'm trying to declare and use a variable in my batch file. It looks like it should be simple. Is this the only way of using local-variables in batch scripts? – parasrish Jun 16 '16 at 9:01.

A number of low-cost powered USB hubs are known to have caused problems. Members of the Raspberry Pi forums have reported low power or no power at all in some cases. The following is a list of specific Powered USB Hubs which appear to be fault-free. Please note that these do not take into account powering the Raspberry Pi from the hub, in addition to its peripherals. If you use a powered hub and the Raspberry Pi PSU together consider powering them from the same power bar with switch, so you can turn them on simultaneously., especially if the HUB tries to feed the Raspberry Pi through their interconnect cable, due to the 100 mA limiting fuse in the Raspberry Pi, the Raspberry Pi will be partially powered which may cause problems (unwanted writes to the SD card). Contents • • • • • • • • • • Raspberry Pi Specific Hubs Recently, two new hubs have been designed and manufactured specifically for the Raspberry Pi. Guaranteed to provide no back power to the unit.

These are • from The Pi Hut •. One of the 4 USB ports supplies the Raspberry Pi with dedicated full 1 A power over a standard USB A to micro B cable. (Order cable separately.) See Raspberry Pi foundation September 9, 2013 news:.

This new USB hub was specifically designed to integrate with the Raspberry Pi Zero • from MSL Digital Solutions Working USB Hubs. USB hub Raspberry Pi power hookup schematic. On the left side a USB A to micro B cable supplies power from the hub to the Raspberry Pi. The thick red and gray overlays indicate the +5 V and ground sides of the power circuit from hub power adapter to Raspberry Pi micro B power port.

The thick red branch terminating at the hub diode emphasizes its role in preventing back-powering of the Raspberry Pi through the hub mini B port. On the right side a USB A to mini B cable provides the data path between the Raspberry Pi host and hub. The dashed lines indicate the differential signal path connecting pins 2 and 3 of the USB A and mini B ports. A powered USB hub is required to attach high power USB devices to the Raspberry Pi. In this case it may be desirable to power the Raspberry Pi from the USB hub instead of in the usual manner from a separate power supply. This power hookup requires two USB cables between Hub and Raspberry Pi, which are both shown on the power hookup schematic. The cable on the left side supplies power and that on the right is a standard USB cable that would be required to connect the Raspberry Pi to any USB hub or other USB device.

The schematic also shows two important features of the USB hub internal power wiring that are required to correctly power the Raspberry Pi. First, the hub coaxial power input directly connects to the USB A output ports. This allows the Raspberry Pi to skip the usual process of asking the hub to switch it from a 100 mA low power to a 500 mA high power device and to exceed even this high power limit so that it can meet its typical power requirements of 700 mA or more. Second, the hub diode prevents back-powering, that is, current cannot flow in the reverse direction from the hub coaxial power connector back out to the micro B input port and into the Raspberry Pi. USB hub power circuitry tests This section describes two tests that will verify that a USB hub has the correct power circuitry.
