    To filter cryptocurrency transactions using wildcard characters in SQL Server, you can use the LIKE operator along with the '%' wildcard character. For example, to search for transactions with a specific prefix in the transaction ID, you can use the following query: SELECT * FROM transactions WHERE transaction_id LIKE 'prefix%' This will return all transactions with a transaction ID that starts with 'prefix'. You can also use the '%' wildcard character at the end of the pattern to search for transactions with a specific suffix. Keep in mind that wildcard searches can be resource-intensive, especially if you have a large number of transactions. So, it's important to optimize your queries and use appropriate indexing to improve performance.

    If you want to search for transactions that match a specific pattern, such as transactions with a specific prefix or suffix in the transaction ID, you can use wildcard characters in SQL Server. The '%' wildcard character represents any sequence of characters, while the '_' wildcard character represents any single character. For example, to search for transactions with a specific prefix in the transaction ID, you can use the following query: SELECT * FROM transactions WHERE transaction_id LIKE 'prefix%' This will return all transactions with a transaction ID that starts with 'prefix'. Similarly, you can use the '%' wildcard character at the end of the pattern to search for transactions with a specific suffix. Remember to use appropriate indexing and optimize your queries to ensure efficient searching.
