Multi-DB Querier allows running the same SQL queries on multiple databases with similar structure at once. If running query returns resulting table, it can be exported to file of specified format. The tables from different databases can be either consolidated in one file or the result for each database can be exported to separate file. Possible output formats: Text (TXT), comma-separated values (CSV), dBase (DBF), XML, HTML, RTF, Microsoft Excel (XLS). Multi-DB Querier can work with databases via BDE or ADO. Multi-DB Querier was tested on databases of the following types: Paradox (via BDE), Interbase (via BDE), Microsoft Access (via ADO), dBase (via BDE and ADO) and Oracle (via BDE and ADO),. Theoretically, it can work also with other database types, supported by these two database engines. Connection parameters for each database are stored in the file of internal format, so if they are specified once, then there is no need to provide them again. The names of the most recently used SQL files are also stored. The program can run multi-statement scripts. Each statement must be separated by SQL terminating character or string, which is specified by the user. SQL queries are edited in convenient SQL editor with syntax highlighting. The most important operations can be performed also via command line.
