Abstract: {QDB} is a collection of {IDL} and {C} routines that provides a query interface to the Large Angle Spectrometric Coronograph (LASCO) databases maintained under the Sybase database management system. {IDL} widgets are used extensively to display the databases, tables, columns, and on-line help. This is a fully automated process---no code modification is required to reflect database changes such as adding/dropping databases, tables, or columns. Standard Query Language ({SQL}) is used to build a query based on the user selection. This query is then passed via Remote SHell (rsh) to two {C} routines that access the Sybase Open Client Database library to execute the query. The result is returned in an {IDL} structure. Another set of {IDL} routines optionally displays or manipulates the data in this structure.
