Let’s explore this topic together and improve your skills in the field of Java!
Question content
_______ object is used to execute static SQL statements and obtain their results.
- a) Statement
- b) Database
- c) Result set
- d) sql
According to me the correct answers are "statement" and "result set", but when I argued to sir that both of these are correct answers, he denied this and said that the only correct answer is "statement". Can someone give a proper explanation why they are both correct, the answer should be SQL since it has both Statement and Resultset.
Solution
ResultSet
Does not execute the SQL statement. there has never been.
Statement.execute()
Called to execute the SQL statement and return ResultSet
. therefore:
- It executes the SQL statement, and
- It gets the result in the form of
ResultSet
.
So if you need to choose one of these four options:
- a)
Statement
is the correct answer; see above. - c)
ResultSet
is not the correct answer; see above. - b) and d) are not correct answers because there is no such thing as "sql object" or "db object" in the JDBC model.
And Statement
ResultSet
is not an option. If this were an option, it would also (arguably) be correct.
In short, "Sir" is correct and you are wrong. Just accept it.
The above is the detailed content of _______ objects are used to execute static SQL statements and obtain their results.. For more information, please follow other related articles on the PHP Chinese website!

Most users use Excel to process table data. In fact, Excel also has a VBA program. Apart from experts, not many users have used this function. The iif function is often used when writing in VBA. It is actually the same as if The functions of the functions are similar. Let me introduce to you the usage of the iif function. There are iif functions in SQL statements and VBA code in Excel. The iif function is similar to the IF function in the excel worksheet. It performs true and false value judgment and returns different results based on the logically calculated true and false values. IF function usage is (condition, yes, no). IF statement and IIF function in VBA. The former IF statement is a control statement that can execute different statements according to conditions. The latter

Oracle database log information can be queried by the following methods: Use SQL statements to query from the v$log view; use the LogMiner tool to analyze log files; use the ALTER SYSTEM command to view the status of the current log file; use the TRACE command to view information about specific events; use operations System tools look at the end of the log file.

To query the MySQL database storage structure, you can use the following SQL statement: SHOW CREATE TABLE table_name; this statement will return the column definition and table option information of the table, including column name, data type, constraints and general properties of the table, such as storage engine and character set.

Export query results in Navicat: Execute query. Right-click the query results and select Export Data. Select the export format as needed: CSV: Field separator is comma.

MySQL transaction processing: the difference between automatic submission and manual submission. In the MySQL database, a transaction is a set of SQL statements. Either all executions are successful or all executions fail, ensuring the consistency and integrity of the data. In MySQL, transactions can be divided into automatic submission and manual submission. The difference lies in the timing of transaction submission and the scope of control over the transaction. The following will introduce the difference between automatic submission and manual submission in detail, and give specific code examples to illustrate. 1. Automatically submit in MySQL, if it is not displayed
