Hi,
I have a .net applicaition whose data store are 50 old fpw26 free tables. UPDATES, INSERTS and DELETES are working just fine. One of my SELECT statements is a little slow and I am sure that it is because the VFP engine connected to ado.net does not like the lack of optimization. I build the pieces to my select statment on the fly just before I send it. tcLastNameFragment is passed to my GetListFromNameFragment method as a parameter.
DataSet GetListFromNameFragment(string tcLastNameFragment)
{
Ufrag = '%'+UPPER(tcLastNameFragment)+'%' ;
cnLEN = TRANSFORM(LEN(tcLastNameFragment));
SUBY = " SUBSTR(UPPER(title),1," + cnLEN + ") like '" ;
lcSelectStatement = "SELECT * From c:\patients.dbf WHERE" + SUBY + Ufrag + "'" ;
more code ........
If I pass "GOR" to the method, the select statement will return 3 the following 3 names as it should:
GORE
GORIN
GORY
If I pass in "T" to the method, every name that starts with "T" is found.
Select statement works but lacks opitimization.
Any thoughts?
Neil
