Generates an insert string based on the data you supply, and runs the query. You can either pass an array or an object to the function.
Here is an example using an array:. Note: All values are escaped automatically producing safer queries. It can be used instead of passing a data array directly to the insert or update functions:.
If you use multiple function called they will be assembled properly based on whether you are doing an insert or an update:. To illustrate the difference, here is set used both with and without the escape parameter. Generates an update string and runs the query based on the data you supply. You can pass an array or an object to the function. You can optionally pass this information directly into the update function as a string:.
Generates an update string based on the data you supply, and runs the query. The first parameter will contain the table name, the second is an associative array of values, the third parameter is the where key. The first parameter is the table name, the second is the where clause. I feel is a good solution. Can exceptions contain links to the docs? That might be helpful, too. I also feel that the docs should clarify more specific which builder functions can be used in the model as a mixin and which should not.
I agree with Lonnie for the rest. The intention was godd but it is now causing confusion so this should be fixed by documentation. In a such case getCompiledSelect should be limited on the model since it is an instance of QueryBuilder class. It is a bit strange to have some methods working and some don't. In this moment getCompiledSelect can be used with no errors, but it does not take care of soft deletion. Soft deletion is functionality in the Model. Shouldn't the Model provide a way to get compiled SQL?
But I can't tell the correct usage of the Model. Here's how I think about it: use the Model methods where available, but the QB methods are there to supplement. The primary reason it got mixed it at all is so you didn't have to write custom methods in the model whenever you wanted to filter something, not just get all results. That's much better than CI3, but still requires lots of custom methods when you want only the students that went to a certain school.
With it mixed in, you can now do where and orderBy and limit without making a custom method, if you don't want to. And yes, I like , and approved it with one tiny comment. Skip to content. Star 3. If you intend to write your own queries you can disable this class in your database config file, allowing the core database library and adapter to utilize fewer resources. Runs the selection query and returns the result. Can be used by itself to retrieve all records from a table:.
Please visit the result functions page for a full discussion regarding result generation. This method simply returns the SQL query as a string. This is useful if you need a compound select statement where automatic escaping of fields may break them. You can optionally include a second parameter to rename the resulting field.
If you need a specific type of JOIN you can specify it via the third parameter of the function. Options are: left, right, outer, inner, left outer, and right outer. All values passed to this function are escaped automatically, producing safer queries. There are 2 possible syntaxes, 1 argument or If you are using a database that CodeIgniter escapes queries for, you can prevent escaping content by passing an optional third argument, and setting it to FALSE.
The second parameter lets you set the direction of the result. If you choose the RANDOM direction option, then the first parameters will be ignored, unless you specify a numeric seed value. Random ordering is not currently supported in Oracle and will default to ASC instead. Collectives on Stack Overflow. Learn more. Asked 5 years, 3 months ago.
