![]() ![]() This page is also a great reference to keep handy in case you forget how to do something like change the data type, or import tables. ![]() TakeawaysĬongrats! If you made it here, you now have a pretty good idea of how to use SQLite Browser. It’s important to remember to change the data types as soon as you import data into SQLite Browser. Notice it now only returns 61 rows! And these are the correct rows – with total budgets over $60,000. Tip: To change an existing primary key without creating a secondary index from that primary key, use DROP CONSTRAINT. there is no comma separating the two this can be resolved later with the Forensic Browser. insert into emp (empid, empname, empdept, empsalary. alter table emp add column deptid For confirmation add a single row as follows. ![]() Suppose a user needs to add a deptid column into the emp table at that time user can use the following statement as follows. Now go back to the Execute SQL tab and try running the query again (just click the triangle again to re-run it). The keen-eyed among you will have noted that the lat and long is actually a single column, i.e. Now we can perform the add column by using the following statement as follows. Finally, change the Type dropdown for the total_budget column to integer. You can tell you’ve selected it because it should be highlighted in blue. Go back to the Database Structure tab, and click on the ad_info table. Since SQLite Browser automatically imports all columns in all tables as TEXT, we need to manually change the data type of the non-text columns. Don’t worry, we can fix this! Modify the Column Types in the Tables So it isnt’ recognizing total_budget as a number, and therefore doesn’t know how to find values greater than $60,000. Why? DB Browser imports all columns as text columns by default. We still go the same number of rows in the result (149), and there are still rows that have a total_budget of greater than $60,000.
