This example code was forked from CharlesMendes for ease, but other projects exhibit the same iOS SQLite failure after 500-1000 cycles.Īny input on the cause / fix is appreciated. Using collections will only increase the number inserts possible until failure.ģ - Remove the executeSql call so you have an empty transaction - failure still occurs.Ĥ - Replace the test with WebSQL - failure still occurs.ĥ - Switch between SQLite and WebSQL by chaning the DB open logic in app.js.Ħ - See issue filed with brodysoft/Cordova-SQLitePlugin: This should simulate real world use of an app lifecycle. > Watch the log file (or console in XCode) to see the callbacks stop and the plugin goes deaf.Ģ - Change loop count to 100 and repeat test by clicking Insert button multiple times. This is a required step if you want to create a performant application that doesn't block your UI if the database contains large amounts of data.Cd ionic-sqlite-1000-transactions-ios-bugĬat /ionic-sqlite-1000-transactions-ios-bug/platforms/ios/cordova/console.log executeSql(null) or transaction.executeSql(undefined) the plugin throws an exception while (WebKit) Web SQL indicates a transaction failure. Retrieve data from the SQLite database in small chuncks. In the next part, we are going to improve the data read operation by adding pagination so we can In this tutorial, we continued building our simple real world cross platform mobile application for managing products stock with Ionic 6 by implementing the SQLite CRUD (Create, Read, Update and Delete) operations. Public create ( tableName, item )įor now, we just use a select * SQL statement and we build the query with TypeScript string templates using the interpolation operator then we execute the query against the database with the executeSql(sqlText,values) method. Let's now see an implementation of the create() method which takes two parameters, tableName which refers to the name of the SQL table and item which holds the data to insert: See also how to use TypeORM with SQLite database and Ionic 6 Creating SQLite Data
