The Query Tabular Galaxy tool loads any number of tabular datasets into a new or existing SQLite database allowing the full power of a SQL query to produce a new tabular output. Long, complicated workflows of Galaxy text manipulation tools can be replaced by Query Tabular in a single step.

The Query Tabular tool provides default names for tables: t1, t2, etc. and columns: c1, c2, etc., but a user can specify meaningful names for tables and columns. When specifying names for columns, a user can choose to load only those columns that are given names.

Regex functions are added to sqlite connections so that re.search, re.match, and re.replace functions are available for use in the SQL query.

Line filters can be applied while reading tabular input files to include, exclude, or modify lines before entering the values as rows in the database table. A column replace line filter can use a regex to change a date value to the SQLite recognized format. A normalize filter can convert list fields in the input to first normal form with an individual list item per row.
