Helper for the great plugin Cordova-sqlite-storage
This is a helper for plugin Cordova-sqlite-storage (https://github.com/litehelpers/Cordova-sqlite-storage). The goal is make more simple the use of the plugin (already excellent), because I like to use shorter more maintainable code.
Important In order to use this component, you must first install Cordova-sqlite-storage (https://github.com/litehelpers/Cordova-sqlite-storage).
<script src="db.js"></script>
In sqlscripts/setup:
CREATE TABLE IF NOT EXISTS
schools (
school_id int PRIMARY KEY ASC,
school_name text
);
// Variable to store the parameters, if any var params = {}; params['schoolId'] = 9901;
// Variable for store the function to apply // Expects an object, assoc array.
// prints: // [{ school_id: "9001", "school_name":"PABLO LIVAS"},{ school_id: "9002", "school_name":"ADOLFO PRIETO"}] var fn = function ( result ) { console.log( result ); };
// Call query db.query( sql, params, fn );
/* Anothe example */ // We can also declare params simply with ?
// Variable to store the sql var sql = "SELECT * FROM schools WHERE school_id = ?";
// Variable to store the parameters, if any var params = [9901];
// Variable for store the function to apply // Expects an object, assoc array.
// prints something like: // [{ school_id: "9001", "school_name":"PABLO LIVAS"},{ school_id: "9002", "school_name":"ADOLFO PRIETO"}] var fn = function ( result ) { console.log( result ); };
// Call query db.query( sql, params, fn );
To query with no parameters:
```js
db.query(
sql,
null,
fn
);
// Name of the table
var tableName = "schools";
// Object with data
var tableData = {
"shool_id": 9003,
"school_name": "MOISEIS SAENS";
};
// Array with list of key fields
var keyFields = ["school_id"];
// Call upsert
db.upsert(tableName, tableData, keyFields);
// Table name
var tableName = "schools";
// Object array (the data)
var tableData = [
{
"shool_id": 9003,
"school_name": "MOISEIS SAENS";
},
{
"shool_id": 9004,
"school_name": "JERONIMO SILLER";
}
];
// Array with a list of the key fields
var keyFields = ["school_id"];
// Call bulkUpsert
db.bulkUpsert(tableName, tableData, keyFields);
The use is simple, useful, short and elegant.
