The difference between execute and query methods in thinkphp _php tutorial

Both the Execute () and the query () methods in thinkphp can enter SQL statements directly into the parameters. The difference is that execute () is typically used to execute SQL statements such as INSERT or update, and query is commonly used to execute statements such as SELECT. The Execute () method returns the number of records affected, and if you execute a SELECT statement for SQL, the result will be the total number of records for the table.

Here are a few specific examples to illustrate:

$model =m ("MyTable");

$result = $model->execute (' select * from MyTable '); Total row count (number) will be returned

The query () method returns the data set, which returns False if the queries are incorrect or if there are no query results

$result = $model->query (' select * from MyTable '); Will return a two-dimensional result array or false
