Yes IE supports Java. Let me check on the failure to load.

RE: MI SQL question
Hi Fran, Not sure what you are after - if it is the SQL syntax used by Mapinfo/MapBasic try this: 1. Create an ODBC SQL link to a database using MapInfo (menu = File>Open ODBC table) 2. Save the table 3. Open the newly created .tab file in notepad or other text editor The table definition includes a Query statement - this is in effect the SQL eg. "\DATALINK\Query" = "select `DataSet_ID`, `Dataset_name`, `Dataset_creation_date`, `Dataset_author`, `Dataset_owner` from `C:\Userdata\mat\Database\MAT`.`TblDataSets` where (`DataSet_ID` = 15) and (`Dataset_name` like 'test')" Similarly, if you create an SQL query of a table using Mapinfo (menu = Query>SQL select) and save the workspace, you can view the workspace file in a text editor to see the select statement. However, I suspect that you are trying to find out the syntax to be used in the MapInfo Query>SQL select dialogue (to avoid the dreaded errors that you get when you try to verify your syntax!), and the only method I have found is trial and error or looking at one that worked previously!

RE: MI SQL question
Fran, The MapBasic help file gives you this sort of information. I have attached the following excerpt which relates to SQL selections (using MB, but same principles apply). Also from the MB help, on the like statement: The pattern_string parameter can contain the following wild-card characters: _ (underscore) matches a single character % (percent)matches zero or more characters I agree that this is not well documented in the MapInfo help. If you search for wildcards, this info is under the heading "Comparison Operators". This is in the index under "Operators" - so the indexing is pretty poor.

Re: MI SQL question Obtaining counts
Fran: I believe what you are looking for is the "group by" column. If you "group by" school, then the count of 0s and 1s will be grouped by school.
