Who/what will populate the data into these tables?ĭo we need processes to automatically populate the tables?ĭata inception has to happen somewhere. How much data will be populated into these tables? This factor is often overlooked and can easily cause a database project to fail. If the data is not maintainable and kept up to date, then the design has already failed. Populating data should be part of the planning process too. But design is not the only factor to consider. It might be a good idea to draft a diagram showing the tables and how they are related. What will their parent/child relationships be? What tables will I need to fulfill those requirements? Get a free trial today and find answers on the fly, or master something new and useful.

When you create your own tables to support your business, it should not be done lightly. Sometimes, though, we will want to CREATE new tables, as well as INSERT, UPDATE, and DELETE records. A SELECT statement is a read-only operation. We have done analysis operations that read data and transform it in interesting ways, but none of this physically changes the data in the tables. So far in this book, we have only learned how to be consumers of data with the SELECT statement. This is Chapter 9 from "Getting Started with SQL," by Thomas Nield any cross-reference links to other areas of the book will be unavailable, as this chapter is excerpted from a larger work. Select the exported database file and open it directly.Thomas Nield will teach SQL Fundamentals for Data, a hands-on online training course for beginners on core database and SQL fundamentals, October 4-5, 2016, from noon to 3 p.m. Select the table to be converted directly to “OK” conversionĪfter the conversion, we open it with sqlitestudio, open SQlitestudio Database – Add database “SQLite DataBase File Path” : Select and create the converted SQLite DataBase File storage Path and nameĬlick “Start The Conversion Process” to Start The Conversion Process The list of available databases under this instance appears on the right side of “Select DB”. “that is, click the” Set “button to the right of the native schema database instance The conversion tool currently used is “Convert SQL Server DB to SQLite DB”.Įnter the SQLSERVER instance Address in “SQLSERVER Address” and use the default Address “. As the same part of the structure of the project still needs the original data table structure, in order to reduce repeated labor, the table in THE SQLSERVER was directly converted into SQLite. How to quickly import and export data in SQLite using SQlitestudio:įirst of all, as the.NET project was transferred to Android, the original database used SQLSERVER. How to use SQlitestudio to quickly import and export data in SQLite: Firstly, since the.NET project is transferred to Android, the original database USES SQLSERVER since the same part structure of the project still needs to use the original data table structure, in order to reduce repetitive labor, the tables in THE SQLSERVER are directly converted into SQLite, and the conversion tool currently used is Convert
