MI true or false in SQL

[Nick Hall]

Dear L-ers,   I have a large MapInfo table that has a logical column (i.e. T or F).   When I come to query that field for the false rows (i.e. where Logical_column = "F") it selects all the true values (i.e. "T").   Also, if I ask the query the other way round and try to select all the rows that don't equal false it does select all the false records (i.e.where Logical_column <> "F").   Can anybody explain this please - it happens in V5, V5.5 and V6.   TIA   Nick Hall Dataview Solutions Ltd "Making Maps Work" Technology House, Lissadel Street Salford M6 6AP ENGLAND   Tel:  +44 (0)161 278 2556 Fax:  +44 (0)161 737 7700 E-mail:  [EMAIL PROTECTED]   WEB:  www.dataview-solutions.co.uk   **HAVE A LOOK AT OUR NEW DATA CATALOGUE ONLINE**   _______________________________________________________ WARNING - THIS E-MAIL TRANSMISSION IS CONFIDENTIAL.
