Question

I have the following string which won’t compile:

String formLookupPull = @'SELECT value1, ''+tableName+'', ''+columnName+'' FROM lkpLookups WHERE ''table'' = '' + tableName + '' and ''field'' = '' + columnName + '';'; 

The offending sections are :

''table'' = 

and

''field'' =  

The compiler is getting all mixed up on the escape sequence. Can anyone see what’s wrong?

Answer 1

The problem is that not all the strings you are concatenating are verbatim string literals, only the first portion of the concatenation is.

In other words,

@'SELECT value1, '' 

is the only verbatim literal in the entire statement to build the final string.

You would need to add @ in front of the rest of your strings to make them all verbatim.

Which would make it look like:

String formLookupPull = @'SELECT value1, ''+tableName+ @'', ''+columnName+ @'' FROM lkpLookups WHERE ''table'' = '' + tableName + @'' and ''field'' = '' + columnName + @'';';
