Query and Join Data Tables with JMP Query Builder

The JMP Query Builder option in the Tables menu enables you to query data tables and save selected data into a new data table. This feature is similar to using the Join command but lets you perform queries before saving the data. For example, you can query SAT data and save only data for 2004 test scores in a data table. You can also include a prompt that lets the user run the query and choose a subset of the 2004 test scores.

See Build SQL Queries in Query Builder for more information about features that also appear in Query Builder for databases.


To join data from different sources (for example, a database and Microsoft Excel), use Query Builder to import the database data into a data table; import the Excel data into a data table; and use JMP Query Builder in the Tables menu to query and join the tables.

When you open a query, data tables in the query open as hidden files that you can open from the JMP Home Window. You can also open the hidden files from the Table panel when you build the query.

If you try to query a Microsoft Excel file that has more than 255 columns, only 255 columns are imported. Instead, select File > Open to open the Excel file in the Excel Import Wizard, and save the file as a data table.
