Hans Leidekker 6df6332198 msi: Reject greater than and less than string comparisons in WHERE clauses. 2009-12-15 11:45:04 +01:00
Nate Gallaher cc366e1282 msi: Add tablename tracking to VIEW_find_column.
This fixes the bug where multiple columns of the same name, but
different tables are members of a join. Any attempt to refer to these
columns will resolve to the first available column with that name,
irregardless of any tablename modifier.

Robert Shearman 9f487ba1de msi: Optimise WHERE operations.
Optimise WHERE operations on matching against strings by adding a new
function find_matching_rows to the views, which eliminates the need to
examine every record when executing a query. Implement this function
in the table using a hash table on the ID stored in the data.
