Most tables have an associated view 2174which displays the information in a more friendly way. Not all data for large tables is fetched 2175immediately. More records can be fetched using the Fetch bar provided. Columns can be sorted, 2176but that can be slow for large tables. 2177<p>There are also tables of database meta-information. 2178For SQLite3 databases, the sqlite_master table is included. 2179For PostgreSQL databases, information_schema.tables/views/columns are included. 2180<h3>Find</h3> 2181Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match. 2182Refer to Python documentation for the regular expression syntax. 2183All columns are searched, but only currently fetched rows are searched. 2184<p>N.B. Results are found in id order, so if the table is re-ordered, find-next and find-previous 2185will go to the next/previous result in id order, instead of display order. 2186""" 2187 2188# Help window
