The DATETIME data type is used to store high-precision date and time information, ranging from 0001-01-01 00:00:00 to 9999-12-31 23:59:59.99999999, and the syntax is DATETIME(precision), where precision specifies the accuracy after the decimal point (0-7), and the default is 3. It supports sorting, calculation, and time zone conversion functions, but needs to be aware of potential issues when converting precision, range and time zones.

How to create tables using SQL statements in SQL Server: Open SQL Server Management Studio and connect to the database server. Select the database to create the table. Enter the CREATE TABLE statement to specify the table name, column name, data type, and constraints. Click the Execute button to create the table.

SQL IF statements are used to conditionally execute SQL statements, with the syntax as: IF (condition) THEN {statement} ELSE {statement} END IF;. The condition can be any valid SQL expression, and if the condition is true, execute the THEN clause; if the condition is false, execute the ELSE clause. IF statements can be nested, allowing for more complex conditional checks.

The DECLARE statement in SQL is used to declare variables, that is, placeholders that store variable values. The syntax is: DECLARE <Variable name> <Data type> [DEFAULT <Default value>]; where <Variable name> is the variable name, <Data type> is its data type (such as VARCHAR or INTEGER), and [DEFAULT <Default value>] is an optional initial value. DECLARE statements can be used to store intermediates

SQL paging is a technology that searches large data sets in segments to improve performance and user experience. Use the LIMIT clause to specify the number of records to be skipped and the number of records to be returned (limit), for example: SELECT * FROM table LIMIT 10 OFFSET 20; advantages include improved performance, enhanced user experience, memory savings, and simplified data processing.

There are two ways to deduplicate using DISTINCT in SQL: SELECT DISTINCT: Only the unique values of the specified columns are preserved, and the original table order is maintained. GROUP BY: Keep the unique value of the grouping key and reorder the rows in the table.

Common SQL optimization methods include: Index optimization: Create appropriate index-accelerated queries. Query optimization: Use the correct query type, appropriate JOIN conditions, and subqueries instead of multi-table joins. Data structure optimization: Select the appropriate table structure, field type and try to avoid using NULL values. Query Cache: Enable query cache to store frequently executed query results. Connection pool optimization: Use connection pools to multiplex database connections. Transaction optimization: Avoid nested transactions, use appropriate isolation levels, and batch operations. Hardware optimization: Upgrade hardware and use SSD or NVMe storage. Database maintenance: run index maintenance tasks regularly, optimize statistics, and clean unused objects. Query

Methods to judge SQL injection include: detecting suspicious input, viewing original SQL statements, using detection tools, viewing database logs, and performing penetration testing. After the injection is detected, take measures to patch vulnerabilities, verify patches, monitor regularly, and improve developer awareness.
