Incorrectly, you cannot select some values from the same table first, and then update the table (in the same statement). For example, the following SQL:Delete from the TBL where ID in(Select Max (ID) from TBL a where EXISTS(Select 1 from the TBL B where A.tac=b.tac GROUP by TAC has count (1) >1)Group BY TAC)Rewrite it to the following line:Delete from the TBL where ID in(Select a.ID from(Select MAX (ID) ID from tbl a where EXISTS(Select 1 from the TBL B where A.tac=b.tac GROUP by TAC has count (

When importing data from Excel to SQL Server, there is an error in importing due to the Long data in the table (if the data is not very long, within 255, no error occurs):Cause of Error:Import and export of SQL Server to determine the data table for each field type, take the first few rows of each field in the Excel table (3 rows) to distinguish. If the first 3 is a string of less than 255, it is set to the nvarchar (255) type, so if the number of characters in the fourth or later data is greate

, and the ID value is the maximum value of the table plus 1, so we will write about the following statement: MySQL>insertintovalues((selectmax from T1), ' You ' ); 1093 (HY000): You can"T1' for update in from clauseStill reported the same mistake.

Analysis reason: This is the start of the Shell editor when the problem occurs, I analyze he may be a server connection problem. Workaround: In the MONGO installation file, create a mongo.config file that reads as follows: If you start MONGO every time, it will be a very troublesome thing to start from CMD. It is co

In the form of batch file, first solve this problem really is not I am good at, thanks to warm uncle help me. Because I found out that the DOS code is quite different from the batch file. Here is my solution to this problem when the harvest, of course, without the help of small warm. Here are some of the absolute and relative paths written in the batch fileFirst I try the following method, which is written in the batch file below and then the DOS environment to assign the 1% parameterHowever, th

When you delete a scheduled task for a previously created SQL, the title error message pops up, and the reason for the error is that the SA password has changed, causing the error to occur because the SA password and the current password are incorrect when you delete it.Workaround:1. In the edit window of the scheduled task, locate the management connection2. Managing the SA connection when creating this scheduled task3. You can change it to "Use Windows NT ..." or you can fill in the Password b

Therefore, in the case of fixed camera, the background subtraction algorithm is used in most tracking algorit

reliable transmission of large amounts of data between host systems (initiator initiator) and storage devices (target targets) on TCP/IP networks.The topology of the complete iSCSI system is as follows:iSCSI simply means that the SCSI instructions are encapsulated in the TCP/IP protocol and transmitted over Ethernet. ISCSI enables the transfer and operation of the SCSI protocol over an IP network, enabling it to perform data access on such high-speed

Profile tracking Objects with complex shapes cannot be expressed in simple ry. The contour-based method provides a more accurate shape description. The main idea of this method is to use the target model created in the previous frame to find the target region of the current frame. The target model can be a color histogram, a

Use iSCSI Target to create centralized security storage (1) ISCSI is a block-level protocol used to share original storage devices through TCP/IP networks, you can use an existing IP address and ethernet address, such as a nic, vswitch, or vro, to share and access storage through the iSCSI protocol. ISCSI target is a remote hard disk provided by the remote iSCSI server (

After you use add_custom_target of cmake to create a custom target, you must add this target to the all dependency. Otherwise, the generated makefile will not execute the target content. This may cause a problem. If you need to compile the following directory: Exist, that is, there will be several add_custom_target (all. It may not matter if you enter a separate

After using CMake's add_custom_target to establish a custom target, the target must be added to all dependencies, otherwise the generated makefile will not execute the target content.
