Single quote in SQL pass through

I am having trouble with names that contain the apostrophe character when I use SQL pass through.

My SQL uses:
WHERE cont_sub_type LIKE '&IN_CONT_SUB_TYPE'

and the problem is &IN_CONT_SUB_TYPE evaluates to 'Bob's Place'.

You can pass 'Bob''s Place' to SQL (note the repeated single quote) and all is well. So how do I replace the single quote with double single quotes?
I can't use STRREP as all arguments are surrounded by single quotes which gets very confusing and I don't thik WebFOCUS likes double quotes around the arguments.

Did you try &IN_CONT_SUB_TYPE.QUOTEDSTRING ?

not sure i understand, but if you want to replace ' with ", that's easy.
CTRAN (character translation) function
ascii bytval for ' is 39
ascii bytval for " is 34
CTRAN(charlen, string, decimal, decvalue, outfield)
NEWVALUE/A30=(30,OLDSTRING,39,34,'A30');

NightOwl,

If you only have the possibility of one apostrophe then you could tokenise the variable and rebuild it -
-* File sql_apostrophe.fex
-SET &IN_CONT_SUB_TYPE = '''Bob''s Place''';

-SET &fst_token = GETTOK(&IN_CONT_SUB_TYPE, &IN_CONT_SUB_TYPE.LENGTH, 1, '''', &IN_CONT_SUB_TYPE.LENGTH, 'A&IN_CONT_SUB_TYPE.LENGTH');
-SET &lst_token = GETTOK(&IN_CONT_SUB_TYPE, &IN_CONT_SUB_TYPE.LENGTH, -1, '''', &IN_CONT_SUB_TYPE.LENGTH, 'A&IN_CONT_SUB_TYPE.LENGTH');
-SET &IN_CONT_SUB_TYPE1 = &fst_token || '''''' || &lst_token;

-? &IN_CONT_SUB_TYPE


Will give you output of -
 CURRENTLY DEFINED & VARIABLES STARTING WITH 'IN_CONT_SUB_TYPE':
 &IN_CONT_SUB_>= 'Bob's Place'
 &IN_CONT_SUB_>= Bob''s Place

With the second (suffixed 1) being the variable you would use.

Thanks all. I used STRREP and if you use enough single quotes then it actually works.
STRREP(&IN_CONT_SUB_TYPE.LENGTH, &IN_CONT_SUB_TYPE, 4, '''', 2, '''''', &IN_CONT_SUB_TYPE.LENGTH, 'A255');

This will replace all single quates with two single quates and then SQL is happy.

Scary stuff.

The .QOUTEDSTRING works better.

Thanks all.

N.Selph,

Very useful information, thankyou.

Where did you learn about the .QUOTEDSTRING extension? Any idea when it first appeared?

That snuck up on me too. It was mentioned in a case I had with IBI, and then I looked up the documentation. It is mentioned in the 5.3 New Features manual.

Interesting, though I think I need a drink after reading the doc!

And how this works in Dev Studio, I wonder.
