Why can't I copy content from PDF in Microsoft Edge? Show me how resolve the issue.

Here are some examples of things I can help answer:

- Math problems and concepts (algebra, geometry, calculus)

- Sciences such as physics or chemistry questions

- English grammar rules and writing tips

- General knowledge inquiries (history, geography, literature)

- And much more! Just let me know what you have in mind and I'll see if I can provide the information that you need. ??

If there is no particular question, feel free to share a joke or ask about my day! Have a great one! :D How do you speed up selecting and computing from a large data set in sql server

To improve the performance of querying and computations on a large dataset in SQL Server, you can consider several best practices:

1. Indexes: Properly designing indexes for your tables is crucial as it significantly speeds up data retrieval by allowing the database engine to quickly locate the required data. Be sure that you have appropriate non-clustered indexes on columns used in your query's WHERE, JOIN conditions and ORDER BY clauses. You can use the Database Engine Tuning Advisor or DMVs (Dynamic Management Views) to help determine if indexes are needed and how they should be designed.

2. Partitioning: Large tables can benefit from partitioning, dividing them into smaller more manageable pieces based on a logical or physical boundary such as time or geographic location. This helps in faster data access and improves query performance by reducing the amount of data that needs to be scanned for a particular query.

3. Query optimization: Write efficient queries, making use of SQL Server features like JOINs instead of subqueries and using the EXISTS keyword over IN when checking for existence. You can also make use of query hints to optimize your queries or leverage SQL Server's built-in optimization features like Query Store and Automatic Plan Correction.

4. Memory management: Allocating enough memory to the server or specific query can help improve performance, as it allows SQL Server to cache more data in its memory and reduce disk I/O which is a bottleneck for large datasets. You can use tools like Memory Profiler or SQL Server Management Studio to monitor the server's memory usage and identify any potential issues.

5. Database design: A well-designed database, with appropriate normalization levels and denormalized data where necessary can help reduce the number of joins required in queries. This leads to faster query execution as fewer tables need to be accessed during a query, which ultimately reduces I/O and processing time.

6. Use of appropriate data types: Choosing the correct data type for each column is essential as it allows SQL Server to store, read and process your data more efficiently while reducing storage requirements. Avoid using large or unnecessarily complex data types like VARCHAR(MAX) for columns that don't require it, and make use of the built-in SQL Server date/time or numeric data types.

7. Hardware considerations: Upgrading your server's hardware, like adding more RAM, using faster solid-state drives (SSD), or utilizing parallel processing with multiple CPUs can help significantly improve the performance of querying and computations on large datasets. Why can't I copy content from PDF in Microsoft Edge? Show me how resolve the issue.

It seems that Microsoft Edge does not support direct copying of text or images from PDF files within its built-inPDF viewer. However, you can use an alternative method to work around this issue:

1. Save the PDF file on your computer or save it in OneDrive (if using a Microsoft account). Make sure you have the latest version of Adobe Acrobat Reader installed.

2. Open Adobe Acrobat Reader and open your PDF file from its saved location or OneDrive (if you've uploaded it).

3. Use the editing tools in Adobe Acrobat Reader to copy text, images or information as needed. You can use keyboard shortcuts such as `Ctrl + C` (or `Cmd + C` on Mac) to copy text and the right-click context menu for images.

4. Go back to Microsoft Edge, paste your copied content using keyboard shortcuts `Ctrl + V` (or `Cmd + V` on Mac) as needed in the text box where you want to insert it.

5. Save or submit your work with ease, now that you've successfully copied content from a PDF file using Adobe Acrobat Reader and pasted it into Microsoft Edge.

If saving the PDF or accessing it through OneDrive is not an option, consider alternative methods such as printing to a text file (File > Print > Save As PDF) from within Adobe Acrobat Reader or using more specialized tools like CamelCamelCamel for extracting text.

Keep in mind that some PDF files may be protected by digital rights management (DRM) or other security measures, which can prevent copying even with external tools.
