To echo a query before execution in CodeIgniter, you can use the last_query() method of the $this->db object . This method returns the last executed query as a string. Here's an example:
$query = $this->db->select('*')
->from('my_table')
->where('column1', $value1)
->where('column2 >', $value2)
->get();
echo $this->db->last_query();
In this example, we are selecting all columns from a table named "my_table" where "column1" equals a certain value and "column2" is greater than a certain value. We use the get() method to execute the query and store the result in the $query variable.
We then echo the last executed query using $this->db->last_query().
To echo a query without execution in CodeIgniter, you can use the get_compiled_select() method of the $this->db object. This method returns the compiled SELECT query as a string, without executing it. Here's an example:
$query = $this->db->select('*')
->from('my_table')
->where('column1', $value1)
->where('column2 >', $value2)
->get_compiled_select();
echo $query;
In this example, we are compiling a SELECT query that selects all columns from a table named " my_table " where "column1" equals a certain value and "column2" is greater than a certain value. We use the get_compiled_select() method to retrieve the compiled query as a string and store it in the $query variable.
We then echo the compiled query using $ query .
Note that the get_compiled_select() method only works for SELECT queries, and not for INSERT, UPDATE, or DELETE queries.
