combine three records to one with a sql select()

combine three records to one with a sql select()

combine three records to one with a sql select()

I am facing a complete blackout, it seems, following code, which intents to combine the three records surname,insertion,famname into one record fullname, however somehow my coding is incorrect. Anybody to spot the error?

CODE --> vfp

lcLetter = 'K'
lcSQL = 'Select district, Alltrim(Alltrim(surname)+' '+Alltrim(insertion))+' '+famname As fullnaam, Id from NAW '+;
	IIF(Empty(m.lcLetter),'','where Substr(surname,1) = "'m.lcLetter)+'" order by 1 into cursor junklist nofilter' 

So the cursor should read e.g.
"Koen Piller","1"
"Kyle the Expert","2"



RE: combine three records to one with a sql select()

What does lcSQL contain after the assignment?

What's actually happening? An error? Nothing returned?


RE: combine three records to one with a sql select()


Error: "Command contains unrecognized phrase/keyword"



RE: combine three records to one with a sql select()

You get this error when executing the lcSQL = ... line, right?
You can't have single quotes within a string delimited by single quotes.

A simplified version of your error:


lcSQL = 'Select a+' '+b from Table' 

This has two string literals in this line:
1. 'Select a+'
2. '+b from Table'

And there is a space in between them. Let's say you had these strings in two variables x and y, then in short your code is:


lcSQL = x y 
Do you see what the parser doesn't see a valid phrase in there? Just because your string separation with a space is so short it doesn't look like the end of the string to you, the parser still strictly interprets the same string delimiter the string starts with as the end. There is no parsing in the way "Oh, the user meant it differently". You start a string with a single quote? Fine, the next single quote the parser encounters is the end of that string. Even if no operator follows, but the next single quote string delimiter is starting the next string, which is a phrase error, the parser will not get back into string mode parsing and mend its interpretation, this is simple and strict.

In general it helps to set up your syntax coloring to show strings red, but in this case, the small gap between two strings will not be noticeable by simple syntax coloring.

There is a simple way to get done with such errors in case of complex code like SQL or HTML, where you likely need to use all of VFPs string delimiters single quote, double quote and square brackets within the string: Use TEXT..ENDTEXT
