MesaSQLite makes creating, designing, and altering an SQLite3 database easy. We also use it to edit, summarize, and analyze data for ourselves and clients. Although we build new databases most days, we spend more of our time viewing and editing data. MesaSQLite is set up for this in mind.

MesaSQLite uses the SQLite3 database engine. Here is an overview of MesaSQLite features:

Connections:

Connect to any database visible on a volume
Open a new connection with each new window
Do both of the above at the same time

Structure:

View, add, duplicate, rename, and delete tables
View, add, duplicate, rename, edit, and delete fields on tables
Specify field type, length, nullable, default value, and autoincrement
Add and delete indexes on tables
View the Create Table sql syntax for your tables

Viewing and Editing Content:

Select encoding for viewing your data - encodings: UTF8, Win Arabic, Win Baltic Rim, Win Cyrillic, Win Greek, Win Latin 1, Win Latin 2, Win Vietnamese, K018-R, Shift-JIS, ISO Arabic, SO Cyrillic, ISO Greek, ISO Hebrew, ISO Latin 1, ISO Latin 2
Limit the number of records that load upon table selection
Suppress autoloading of records upon table selection
Build query to limit records using dropdown menus
Limit a recordset from a table by selecting a record count and a starting record
Set a "Load Last" limit that will load the last "n" records in the table
Limit the columns returned in a recordset
Sort a recordset by multiple fields
Make global changes to many records in a showing recordset
Reset column widths for easier viewing after a recordset loads with one click
View totals of numeric columns in a recordset with one click
Add and edit records directly in the listbox view
Delete records directly from the listbox view
Multi-select adjacent or non-adjacent rows for deletion or global editing
Click and drag in the recordset listbox to select cells and make them available to the clipboard
Reorder columns of data using click-and-drag without changing the structure of the table

Special Queries:

Type any query into the custom query field
Read errors and rows returned associated with a custom query
Store favorite queries and keep a history of recent queries

Forerign Keys:

SQLite3 Trigger technology is used to create Foreign Keys whose syntax is stored in the CREATE TABLE suntax of the table. Three triggers are created for each key in order to create and preserve referential integrity between tables
Create, view, and edit your Foreign Keys in the Foreign Key tab

Exporting and Importing Data:

Drop a file containing REALBasic code to generate the database you have built in MesaSQLite
Export a proprietary dump to back-up the structure and content of the database
Export the content screen, custom query result, or table as a csv, tab, or xls file
Import a proprietary dump that can recreate the database from a single file
Import any csv, tab, or xls file into a given table
