SELECT UUID_SHORT(); -> 92395783831158784Note UUID_SHORT() does not work with statement-based replication. UUID_TO_BIN(string_uuid), UUID_TO_BIN(string_uuid, swap_flag) Converts a string UUID to a binary UUID and returns the result. (The IS_UUID() function description lists the permitted string UUID formats.) The return binary UUID is a VARBINARY(16) value. If the UUID argument is NULL, the return value is NULL. If any argument is invalid, an error occurs. UUID_TO_BIN() takes one or two arguments: The one-argument form takes a string UUID value. The binary result is in the same order as the string argument. The two-argument form takes a string UUID value and a flag value: If swap_flag is 0, the two-argument form is equivalent to the one-argument form. The binary result is in the same order as the string argument. If swap_flag is 1, the format of the return value differs: The time-low and time-high parts (the first and third groups of hexadecimal digits, respectively) are swapped. This moves the more rapidly varying part to the right and can improve indexing efficiency if the result is stored in an indexed column. Time-part swapping assumes the use of UUID version 1 values, such as are generated by the UUID() function. For UUID values produced by other means that do not follow version 1 format, time-part swapping provides no benefit. For details about version 1 format, see the UUID() function description. Suppose that you have the following string UUID value: mysql> SET @uuid = '6ccd780c-baba-1026-9564-5b8c656024db'; To convert the string UUID to binary with or without time-part swapping, use UUID_TO_BIN(): mysql> SELECT HEX(UUID_TO_BIN(@uuid));+----------------------------------+| HEX(UUID_TO_BIN(@uuid)) |+----------------------------------+| 6CCD780CBABA102695645B8C656024DB |+----------------------------------+mysql> SELECT HEX(UUID_TO_BIN(@uuid, 0));+----------------------------------+| HEX(UUID_TO_BIN(@uuid, 0)) |+----------------------------------+| 6CCD780CBABA102695645B8C656024DB |+----------------------------------+mysql> SELECT HEX(UUID_TO_BIN(@uuid, 1));+----------------------------------+| HEX(UUID_TO_BIN(@uuid, 1)) |+----------------------------------+| 1026BABA6CCD780C95645B8C656024DB |+----------------------------------+ To convert a binary UUID returned by UUID_TO_BIN() to a string UUID, use BIN_TO_UUID().

This tool allows you to easily generate GUIDs/ UUIDs for your projects or any other purpose. Simply use the default GUID/UUID generated on page load or generate multiple GUIDs/UUIDs as needed. Generate More? Generate in Uppercase Please exercise caution when using these GUIDs. Their uniqueness and suitability are not guaranteed or assured in any way. Use at your own discretion. What is a GUID/UUID? A GUID is a 128-bit identifier used in software applications to ensure uniqueness across different systems and environments. How are GUIDs generated? GUIDs are generated using random numbers combined with predefined formats to ensure their uniqueness. Types of UUID Version Generation Method Key Features Version 1 Generated using timestamp and node ID (e.g., MAC address) Includes time and node-specific information Version 2 Similar to V1, but includes POSIX UID/GID Used for security domain identification Version 3 Generated using MD5 hash of namespace and name Deterministic; same inputs produce the same UUID Version 4 Random or pseudo-random numbers Most common; highly unique Version 5 Generated using SHA-1 hash of namespace and name Similar to V3 but uses stronger hashing Version 6 Reordered timestamp and random data Improves database indexing by preserving timestamp order Version 7 Generated using Unix epoch timestamp and random data Optimized for time-based ordering Version 8 Custom format defined by implementers Provides flexibility for unique use cases How to Identify UUID Version The version of a UUID can be determined by looking at the 13th hexadecimal digit (first digit of the 7th byte) in the UUID string. For example: UUID Structure UUID Format A UUID is typically represented in the following format: 8-4-4-4-12 Example: 123e4567-e89b-12d3-a456-426614174000Uuid Factory Cracked License Key (Updated) - Download

Specific Binary SubtypesMongoDB defines multiple binary subtypes to categorize the binary data. Each subtype suggests how the binary data might be utilized. A common subtype is ’04’ for UUIDs.Inserting and Retrieving UUIDsEnforcing the UUID subtype can ensure applications interpret binary data as intended:// MongoDB JavaScript Shellconst { Binary, UUID } = require('mongodb')// Create UUID instanceconst uuid = UUID();// Save UUID to MongoDBdb.collection('uuids').insertOne({ uniqueId: new Binary(uuid, Binary.SUBTYPE_UUID)});// Retrieve UUID from MongoDBconst document = db.collection('uuids').findOne();const myUuid = new UUID(document.uniqueId.buffer);In these examples, we manipulate the binary data as an UUID object. When retrieving the data, we ensure that the application correctly interprets it as a UUID, not just a set of bytes.Handling Larger FilesFor larger binary files (such as images or video clips), it may be more efficient to use MongoDB’s GridFS specification, which avoids issues with the size limits of BSON documents by storing files in chunks.Using GridFS to Store Large FilesThe gridfs module allows for the streamlined storage and retrieval of large files in MongoDB:// JavaScript using MongoDB Driver with GridFSconst { MongoClient, GridFSBucket } = require('mongodb');const fs = require('fs');// Connect to the MongoDB clientconst client = new MongoClient('connection_string');async function uploadFile(path) { const db = client.db('database_name'); const bucket = new GridFSBucket(db); // Read the file stream and upload fs.createReadStream(path).pipe(bucket.openUploadStream(path.split('/').pop())) .on('error', function(error) { console.log('Error:', error); }) .on('finish', function() { console.log('File uploaded successfully.'); });}uploadFile('/path/to/large/file');Likewise, downloading a file is simply a matter of streaming the file from the database back to the local file system or to another destination.Best Practices for Managing Binary DataHere are some best practices to follow when working with binary data in MongoDB:Use the appropriate binary subtype to aid in data interpretation.Leverage GridFS for storing files larger than the BSON document size limit, which is currently 16MB.Be cognizant of memory usage when working with large binary data in your application.When possible, save references to binary data if the data is reused across documents, rather than duplicating the data itself.ConclusionBy following this tutorial, you should be more comfortable storing, retrieving, and managing binary data in MongoDB. Leveraging BSON’s capabilities and MongoDB’s GridFS, managing binary data alongside traditional JSON documents is efficient and practical for a wide variety of application needs..

Enabled: SELECT age FROM t GROUP BY age-1; To cause MySQL to accept the query, use ANY_VALUE(): SELECT ANY_VALUE(age) FROM t GROUP BY age-1; ANY_VALUE() can be used for queries that refer to aggregate functions in the absence of a GROUP BY clause: mysql> SELECT name, MAX(age) FROM t;ERROR 1140 (42000): In aggregated query without GROUP BY, expression#1 of SELECT list contains nonaggregated column 'mydb.t.name'; thisis incompatible with sql_mode=only_full_group_by Without GROUP BY, there is a single group and it is nondeterministic which name value to choose for the group. ANY_VALUE() tells MySQL to accept the query: SELECT ANY_VALUE(name), MAX(age) FROM t; It may be that, due to some property of a given data set, you know that a selected nonaggregated column is effectively functionally dependent on a GROUP BY column. For example, an application may enforce uniqueness of one column with respect to another. In this case, using ANY_VALUE() for the effectively functionally dependent column may make sense. For additional discussion, see Section 14.19.3, “MySQL Handling of GROUP BY”. BIN_TO_UUID(binary_uuid), BIN_TO_UUID(binary_uuid, swap_flag) BIN_TO_UUID() is the inverse of UUID_TO_BIN(). It converts a binary UUID to a string UUID and returns the result. The binary value should be a UUID as a VARBINARY(16) value. The return value is a string of five hexadecimal numbers separated by dashes. (For details about this format, see the UUID() function description.) If the UUID argument is NULL, the return value is NULL. If any argument is invalid, an error occurs. BIN_TO_UUID() takes one or two arguments: The one-argument form takes a binary UUID value. The UUID value is assumed not to have its time-low and time-high parts swapped. The string result is in the same order as the binary argument. The two-argument form takes a binary UUID value and a swap-flag value: If swap_flag is 0, the two-argument form is equivalent to the one-argument form. The string result is in the same order as the binary argument. If swap_flag is 1, the UUID value is assumed to have its time-low and time-high parts swapped. These parts are swapped back to their original position in the result. A term-uuid function-factory actor. Comunica Term Function Uuid Function Factory Actor.

When retrieving the data, we ensure that the application correctly interprets it as a UUID, not just a set of bytes.Handling Larger FilesFor larger binary files (such as images or video clips), it may be more efficient to use MongoDB’s GridFS specification, which avoids issues with the size limits of BSON documents by storing files in chunks.Using GridFS to Store Large FilesThe gridfs module allows for the streamlined storage and retrieval of large files in MongoDB:// JavaScript using MongoDB Driver with GridFSconst { MongoClient, GridFSBucket } = require('mongodb');const fs = require('fs');// Connect to the MongoDB clientconst client = new MongoClient('connection_string');async function uploadFile(path) { const db = client.db('database_name'); const bucket = new GridFSBucket(db); // Read the file stream and upload fs.createReadStream(path).pipe(bucket.openUploadStream(path.split('/').pop())) .on('error', function(error) { console.log('Error:', error); }) .on('finish', function() { console.log('File uploaded successfully.'); });}uploadFile('/path/to/large/file');Likewise, downloading a file is simply a matter of streaming the file from the database back to the local file system or to another destination.Best Practices for Managing Binary DataHere are some best practices to follow when working with binary data in MongoDB:Use the appropriate binary subtype to aid in data interpretation.Leverage GridFS for storing files larger than the BSON document size limit, which is currently 16MB.Be cognizant of memory usage when working with large binary data in your application.When possible, save references to binary data if the data is reused across documents, rather than duplicating the data itself.ConclusionBy following this tutorial, you should be more comfortable storing, retrieving, and managing binary data in MongoDB. Leveraging BSON’s capabilities and MongoDB’s GridFS, managing binary data alongside traditional JSON documents is efficient and practical for a wide variety of application needs.
