Thank you. It works well as you suggested but:
cName = 'RAFAEL'
vDOB = NULL
cCmd = 'insert into mydatabase.dbo.employees(name,dob) values
(?cName,?vDOB)'
sqlexec(nHandle,cCmd)
the above works, the below construct does not:
Text to cCmd textmerge noshow flags 2 pretext 15
insert into mydatabase.dbo.employees(name,dob) values ('<<cName>>',<<vDOB>>)
endtext
sqlexec(nHandle,cCmd)
Why?
I use text.. endtext most of the time, especially when the statements are
very long and occupy several lines.
Character strings are surrounded with '<<>>', numbers are <<>> and dates
are '<<cDate>>' (dates are converted to the form YYY-MM-DD)
