jdbcTemplate.execute("insert into tb_user(`name`,`password`) value (\"" + name + "\",\"" + password + "\")")

As an AI language model, I cannot execute code. However, the given code is a Java code snippet using the Spring Framework's JdbcTemplate to insert a new record into a database table named "tb_user" with columns "name" and "password". The values for the "name" and "password" fields are passed as parameters to the SQL statement using placeholders. The code is vulnerable to SQL injection attacks if the values for "name" or "password" are not properly sanitized. It is recommended to use PreparedStatement instead of execute method to prevent SQL injection.

jdbcTemplate.execute("INSERT INTO tb_user(`name`,`password`) VALUE(`name`,`password`)");

This line of code is using the Spring framework's JdbcTemplate to execute an SQL INSERT statement on a table called "tb_user". The statement is attempting to insert a new row into the table with two columns: "name" and "password". The values being inserted are the variables "name" and "password", but the syntax used is incorrect. The values should be enclosed in single quotes, like this:

jdbcTemplate.execute("INSERT INTO tb_user(`name`,`password`) VALUES ('" + name + "','" + password + "')");

This will properly insert the values of the variables into the SQL statement.

selectSql="select * from tb_monitor_data_15m"; List<Map<String, Object>> sqlList = jdbcTemplate.queryForList(selectSql); 循环遍历 实现分批每2000次插入数据

String insertSql = "insert into tb_monitor_data_15m (col1, col2, col3) values (?, ?, ?)";
int batchSize = 2000;
int count = 0;
List<Object[]> batchValues = new ArrayList<>();
for (Map<String, Object> sqlMap : sqlList) {
Object[] values = new Object[]{sqlMap.get("col1"), sqlMap.get("col2"), sqlMap.get("col3")};
batchValues.add(values);
count++;
if (count % batchSize == 0) {
jdbcTemplate.batchUpdate(insertSql, batchValues);
batchValues.clear();
}
}
if (!batchValues.isEmpty()) {
jdbcTemplate.batchUpdate(insertSql, batchValues);
}
